'''''Wario Land 4''''', known in Japan as '''''Wario Land Advance: Yōki no Otakara''''' (ワリオランドアドバンス ヨーキのお宝, meaning '''''Wario Land Advance: The Treasure of the Golden Diva''''')<ref>[http://themushroomkingdom.net/games/wl4 <nowiki>http://themushroomkingdom.net/games/wl4</nowiki>]</ref>, is a platform game released for the [[Game Boy Advance]] in 2001. It was later re-released for the [[Nintendo 3DS]] system on December 16, 2011 via the Nintendo 3DS Ambassadors program, just after its ten year anniversary as well as the downloadable Virtual Console game for the [[Wii U]] on May 8, 2014. It is the fifth game overall in the [[Wario Land (series)|''Wario Land'']] series, which is a spin-off of the [[Super Mario Land (series)|''Super Mario Land'' series]]. It is also the final ''Wario Land'' game to be released on a handheld system and the last ''Wario Land'' game for seven years until ''[[Wario Land: Shake It!]]''. In the game, [[Wario]] travels to the [[Golden Pyramid]] after reading a [[:File:WL4-newspaper.PNG|newspaper article]] about a rumor of a [[Legendary Treasure]] hidden inside. His intention is to rob the Pyramid, but he accidentally goes on a quest to save the legendary [[Princess Shokora]] from the money-crazed [[Golden Diva]], evil ruler of the [[Golden Pyramid]]. The game features 2-D graphics with linear transformations (similar to ''[[Super Mario World]]'' and ''[[Super Mario World 2: Yoshi's Island]]''). ''Wario Land 4'' has received very positive reviews from websites and game critics alike, enjoying praise for its soundtrack, collectibles throughout the game, and level design. 

==Story==
[[File:WL4-newspaper.PNG|frame|The newspaper article shown in the game's intro, with the [[Black Cat|Black Cat's]] shadow.]]
[[File:WL4-BlackCat2.gif|frame|left|The [[Black Cat]] almost getting run over in the game's intro.]]
<blockquote>Does [[Wario]] smell treasure again? Oh yes he does! Whilst reading his morning paper and picking his nose, he reads about the legendary [[Golden Pyramid|Pyramid]] of [[Princess Shokora|Shokora]]! With no delay, and even forgetting to take his mid-morning nap, Wario hops into his fantastic [[Wario Car|car]] and heads off to find the Golden Pyramid.

&ndash; Story from the official European ''Wario Land 4'' website
</blockquote>
Sometime before the events of the game, the legendary Golden Pyramid was discovered deep within a jungle. Expeditions were mounted to find the Pyramid's treasure, but a series of accidents prevented anything from being found. The game's story proper begins one morning with Wario reading the newspaper in his house. He reads an article about the Golden Pyramid and all the treasure within, and decides to go steal it for himself. He then hops in his car and heads towards the pyramid, almost running over a [[Black Cat]] on the road.

[[File:WL4-WarioFalling.PNG|frame|left|[[Wario]] falling down a precipice within the Pyramid.]]
Upon arriving at the Pyramid, Wario climbs the outer stairs and heads inside, where he finds the same Black Cat that he almost ran over earlier. The Cat leads Wario deeper into the Pyramid and down a hole. Wario lands in a room near the center of the Pyramid, and proceeds to complete the challenges of its five [[#Passages|Passages]], thus opening the way to the [[Inner Pyramid]], where the evil ruler of the Golden Pyramid, the [[Golden Diva]], resides.

After exploring the [[Golden Passage]] inside the Inner Pyramid, Wario comes face to face with the Golden Diva. The Black Cat then jumps in front of Wario and attacks the Golden Diva, to no effect. The Cat gets swallowed by the Diva, who proceeds to fight Wario. 

After the Golden Diva's defeat, the Pyramid begins to crumble. Grabbing his treasure, and with the Black Cat in tow, Wario hurries to escape the Pyramid. They both make it out, and watch the Pyramid crumble to the ground from a distance. The Golden Diva's jewelry then flies out of the treasure sack and toward the Black Cat. This causes the Cat to change form into Princess Shokora, the ancient ruler of the Golden Pyramid who was turned cursed by the Golden Diva. With the Diva's defeat, the curse could be broken, and the princess thanks Wario by kissing him on the cheek. She is taken away by angels, and Wario takes his treasure to his car and heads home.

[[File:WL4-Shokora Ending.PNG|frame|The black cat transforms into Princess Shokora in front of Wario.]]

The ending cutscene shows Wario speeding through the city, almost running over a cat once more. A newspaper flies into the cat's face, with an article that reads: ''"STEAKS! EAT AS MUCH AS YOU CAN!!"''. The game ends with gold bars forming the words ''THE END''.

==Gameplay==
{{WL4 Golden Pyramid Map}}
[[File:WL4-boss door.PNG|frame|left|Four [[Pyramid Jewel]]s need to be collected in each main [[#Passages|Passage]].]]
Upon creating a new save file, the player can select a [[#Game modes|game mode]] to play as. There are Normal, Hard and S-Hard. The most difficult mode, S-Hard, is unlocked upon completing Hard mode. Gameplay begins in the [[Entry Passage]] which includes [[Hall of Hieroglyphs|one level]] and a boss, [[Spoiled Rotten]]. On completion, the next four areas of the game are revealed. This consists of four more Passages, each with four levels relating to a different theme with a [[#Bosses|boss]] at the end. The four Passages are the [[Emerald Passage]], [[Ruby Passage]], [[Topaz Passage]] and [[Sapphire Passage]]. These can be completed in any order. Once each boss of the five Passages have been cleared, an inner pyramid, (the [[Golden Pyramid]]) is revealed on the main map. This includes one last level, (the [[Golden Passage]]) and the final boss; the [[Golden Diva]].

Unlike [[Wario Land (series)|previous installments]] in the series, Wario is given a Heart Meter, which contains a total of eight hearts. Wario can collect hearts throughout the stages. Collecting one replenishes one heart of the meter. Wario loses a heart by touching a threatening part of an [[#Enemies|enemy]], spikes, etc. He can also fully replenish his meter by opening a [[Heart Box]]. Below the Heart Meter is the Heart Gauge. Most enemies drop a [[Little Heart]] when defeated. Each Little Heart collected fills the gauge by an eighth. Filling it gives Wario an extra heart, and the gauge is then emptied.
                      
Each of the eighteen levels contains four [[Jewel Piece]]s, found within [[Jewel Piece Box|boxes]], that need to be collected. When four Jewel Pieces are joined, they form a [[Pyramid Jewel]]. The color of the Jewels varies on the Passage they are collected in. The player must collect all Jewel Pieces in a Passage to gain access to the boss. A [[Keyzer]] must be collected to unlock the next level. Without the Keyzer, the four Jewel Pieces in that level can still be collected, but the door to the next level remains locked. 
[[File:WL4-Puzzle Room.PNG|frame|left|A [[Puzzle Room]] in [[Palm Tree Paradise]].]]
[[File:Soundroom.PNG|frame|The completed [[Sound Room]].]]
When Wario enters a level, he enters through a [[vortex]], which closes behind him. The only way to open it again is to find the [[Switch (Wario Land 4)|switch]] somewhere in the level. This reopens the vortex and allows Wario to return to the map screen. A [[#List of Time Limits|time limit]] is given to return to the vortex. The player should focus on finding the four Jewel Pieces and the Keyzer before hitting the switch. However, there are some areas that can only be accessed by hitting the switch. This is achieved through the [[Frog Block]]s. The Frog Blocks can be found either solid or transparent. When the switch is hit, all transparent blocks become solid, while all solid blocks become transparent. This opens up new areas that can only be accessed when the switch is hit, so there may be some other Jewel Pieces or maybe even the Keyzer to find in that new area. As soon as the switch is hit, a timer appears on screen. The amount of time given to reach the vortex varies on the level and game mode. If the time runs out, the player's score quickly decreases and the level becomes black and white. When the score reaches zero, Wario is sent back to the main map and must start the level again. In the [[Golden Passage]] (the last level of the game), the switch is placed at the beginning directly under the vortex, so Wario lands on it upon entering the last level. This can make the last level more difficult, as he must recover all four Jewel Pieces and the Keyzer within a time limit.

[[File:WL4-Treasure Restored.PNG|frame|left|[[Legendary Treasure]] and [[Treasure Chest (Wario Land 4)|Treasure Chests]] being restored to the [[Golden Pyramid]].]]
There are two [[Puzzle Room]]s in each level (excluding the [[Entry Passage]] and [[Golden Passage]]). Each one is found in a [[Purple Pipe]], and contains either a [[Diamond (Wario Land 4)|Diamond]] worth 1000pts., or an amount of [[Coin (Wario Land 4)|coins]] that are worth roughly 1000 points when combined. Wario must solve some sort of puzzle to obtain these points, usually using [[Mad Scienstein|Arewo Shitain-hakase]] as an object to throw. Completing these rooms is optional and is not necessary to complete the game, but rather if the player wants to earn a few extra points. Likewise, the player never sees a [[Jewel Piece]] or a [[Keyzer]] is a Puzzle Room, but a [[Heart Box]] can be seen in some rooms.
[[File:WL4-Frog Switch HoH.png|frame|Wario about to exit a level through a [[vortex]].]]
There is also an additional bonus challenge to complete. In every level except for the [[Entry Passage]] and the [[Golden Pyramid]], there is a hidden [[CD]] that can be collected and played in the [[Sound Room]], each containing a different soundtrack. There is a total of sixteen CDs to collect. A [[Karaoke (Medamayaki)|Karaoke]] can also be unlocked, a full song with Japanese vocals. It can be unlocked by getting 10,000 or more points in each of the eighteen levels.

}}
The game records the player's best score (points collected) in each level. The amount of points obtained in a level affects what icon appears on the map screen when standing at the entrance of that level, next to the best score. A score of above 10,000 shows a Gold Crown. 8000 to 9990 show a Silver crown, and a score of 6000 to 7990 shows a Bronze Crown. A score of below 6000 shows no crown.

There are a total of twelve [[Treasure Chest (Wario Land 4)|Treasure Chests]] in ''Wario Land 4''. Three of them are found in each of the four main boss rooms, embedded into the wall in the background. They cannot be touched by Wario at this point. During the boss battle when the time starts to run low (usually under a minute), the Treasure Chests in the background begin to disappear, one by one. Once Wario defeats the boss, the Treasure Chests that are left over are collected and stored in the Golden Pyramid for the final boss against the [[Golden Diva]]. The amount of Treasure Chests collected does not affect the main game. However, the more Treasure Chests Wario obtains on the game's completion, the more beautiful [[Princess Shokora]] appears in the game's ending cutscene.

==Mini-Game Shop==
{{quote2|Have some fun, why don’t cha! Play [[Minigame|mini-games]]!|[[Wario]]|[[Wario Land 4]] instruction manual}}

Prior to the boss room of each passage, there is a [[Mini-Game Shop]] where Wario can play one of three [[Minigame#Wario Land 4|mini-game]]s. If Wario receives a certain amount of points in each of the mini-games, he can earn [[Frog Medal]]s which can be spent at the [[Item Shop (Wario Land 4)|Item Shop]] for items to assist him to defeat the boss of that Passage. The three [[Game Bot]]s run the shop, each hosting a different mini-game. Each mini-game costs 5000 points to play (not including the [[Entry Passage]], which is discounted to 2000.) Points can be earned during normal gameplay.

There are three three mini-games, and they are;
*[[The Wario Hop]]
*[[Wario's Homerun Derby]]
*[[Wario's Roulette]]

There are three different colored Game Bots, each hosting a different mini-game.

==Item Shop==

{{quote2|You thought you could just FIND items? The world doesn't work that way, kid!!|[[Wario]]|[[Wario Land 4]] instruction manual}}

The [[Item Shop (Wario Land 4)|Item Shop]] in ''Wario Land 4'' is a place where Wario can spend his [[Frog Medal]]s in exchange for items. These items assist him in defeating a [[#Bosses|boss]] by dealing pre-damage at the battle's start. The [[Item Shopkeeper|shopkeeper]] is a form of the [[Black Cat]]. This character is very similar to the later-occurring [[Mr. Game & Watch]]. However, a major difference between the two characters is the Item Shopkeeper has eyes in ''Wario Land 4''. 

A table of the nine items and their descriptions is shown below.

|align="center" |[[File:Apple Bomb.png]]
|align="center" |[[Apple Bomb]] 
|The Apple Bomb is an apple with colored stripes across the bottom half. It disguises a [[Bomb (item)|bomb]] that is concealed inside.

She throws the bomb at the boss to inflict a small amount of damage.
|-
|align="center" |[[File:WL4-Blast Cannon.PNG]]
|align="center" |[[Blast Cannon]]
|The Blast Cannon is a grey cannon with multicolored stripes along the barrel. When purchased, it is wheeled to the boss room by the Item Shopkeeper. She then snaps her fingers, causing a bomb to be blasted as a projectile out of the cannon. It hits the boss to inflict a small amount of damage.
|-
|align="center" |[[File:Vizorman.png]]
|align="center" |[[Vizorman]]
|The Vizorman is a seemingly inanimate being that wears a vizor with a white suit with a cape. There is a letter "V" on its chest, with legs bearing multicolored stripes.

|-
|align="center" |[[File:WL4-Bugle.PNG]]
|align="center" |[[Bugle]] 
|The Bugle is a golden bugle with multicolored stripes across the lower half of the tube. It is carried to the boss room by the Item Shopkeeper. She then starts playing a tune on the Bugle, releasing many music notes which fly around the room, eventually hitting the boss and inflicting an average amount of damage. 
|-
|align="center" |[[File:Black Dog.PNG]]
|align="center" |[[Black Dog]]
|The Black Dog is a dog with a huge jaw and bright yellow eyes. It is one of the four items where the Item Shopkeeper transforms into the actual item.

|-
|align="center" |[[File:WL4-LargeLipsSprite.PNG]]
|align="center" |[[Large Lips]]
|The Large Lips is a being with oversized lips, which replace the whole head. The Item Shopkeeper follows Wario to the boss room. She then transforms into the Large Lips, which violently kisses the boss and deal a large amount of damage.

|-
|align="center" |[[File:WL4-BlackDragon.PNG]]
|align="center" |[[Black Dragon]]

|-
|align="center" |[[File:WL4-Smile.PNG]]
|align="center" |[[Smile]]
|The Smile is the only item in the Item Shop that is free. However, it is a joke item. Selecting it only causes the Item Shopkeeper to smile and make a sound effect towards the player. This is a reference to the Japanese McDonald's menu which includes a "Smile" for free.<ref>https://blogs.wsj.com/japanrealtime/2015/05/21/despite-hard-times-mcdonalds-japan-plans-to-smile-again/</ref>

The more effective the item has on damaging a boss, the more Frog Medals it is likely to cost. The price of the items also varies on the [[#Game modes|game mode]], e.g. an item in [[#Game modes|hard]] mode is more expensive than the same item in [[#Game modes|normal]] mode. All items and prices are as follows:

{{quote2|When you find the [[CD]]s thrown around the stages, you'll be able to hear some weird music! Collect 'em all and maybe people will like you!|[[Wario]]|[[Wario Land 4]] instruction manual}}

The [[Sound Room]] is a place found on the main map of the Golden Pyramid, where the player can listen to any [[CD]] that they have collected within the sixteen main passage levels. Each of the sixteen CDs have a unique track recorded on it. A bonus [[Karaoke (Medamayaki)|Karaoke]] can be unlocked by getting 10,000 or more points (a gold crown) in all eighteen levels. The Karaoke may also be temporarily unlocked by pressing Start, Select, Up, L and R together at the same time, while in the Sound Room.

Many of the CDs features remixed audio which was originally elsewhere in the game, such as the [[Switch (Wario Land 4)|Switch]] sound effects in the [[So Sleepy]] CD.

==Game modes==
[[File:WL4 Screenshot - Game Mode Selection.png|frame|Selecting "Hard" mode upon a new save file. Note that "S-Hard" mode is not yet present as an option.]]
Upon creating a file, the player is asked which game mode they prefer to play. The available game modes are as follows:
*[[File:WL4-Normal Mode Sprite.PNG]]
*[[File:WL4-Hard Mode Sprite.PNG]]
*[[File:WL4-S-Hard Mode Sprite.PNG]] (unlockable, by completing Hard mode)

The chosen game mode affects the location of the [[Jewel Piece]]s, how many [[#Enemies|enemies]] are seen in the levels, and the health the player begins with upon entering the level. For example, on S-Hard mode Wario enters the level with only one health point. The game mode also affects the time given to get back to the [[vortex]] after the player hits the [[switch]] (refer to table in the section below). In a few levels on some difficulties, the switch even changes its location. Purchasing items from the Item Shop costs more [[Frog Medal]]s on more difficult modes. The difficulty of [[Mini-Game Shop|Mini-Games]] are generally unchanged across difficulty levels. However, on S-Hard mode, the [[Wario's Homerun Derby|baseball mini-game]] uses a cheerleader who throws very difficult pitches, compared to the lower level modes.

==Wario's Reactions==
{{quote2|Even the powerful Wario gets into some embarrassing situations in this game! I eat too much and get all chubby, a bee stings my face and makes it swell like a balloon, my body catches fire, and all kinds of other bad things happen to me!!|[[Wario]]|[[Wario Land 4]] instruction manual}}

All of Wario's reactions return from the last two games. Wario has a total of ten different reactions in the game, all having a different purpose to assist Wario in progressing through the level. This can include turning into a Bat to reach a high place, or catching fire to break [[Bonfire Block|certain blocks]]. All of the reactions have been based on [[Wario Land (series)|previous games]] in the series, but they are put to more use in ''Wario Land 4''. Wario is invincible in all forms, but touching an enemy merely knocks it aside and not destroy it.  

Below is a table describing all of the reactions (exception: normal Wario).

{|width=100% cellspacing=0 border=1 cellpadding=3 style="border-collapse:collapse;"
|-
!Image 
!Name
!Description
|-
|align="center" |[[File:WL4 Wario1.png]]
|align="center" |[[Wario]]
|Wario in his standard form. He can perform a [[#Controls|ground-pound]], ram [[#Enemies|enemies]] or [[block]]s, crawl to get through thin spaces and throw small objects like enemies or rocks.
|-
|align="center" |[[File:WL4 Wario2.png]]
|align="center" |[[Puffy Wario]]
|Wario after getting stung by a [[Beezley]], or getting struck by the arrow of a [[Bow Balloon]]. His cheeks puff up in a supposed allergic reaction, and he is able to float continually upwards, until Wario hits a ceiling, at then Wario turns back into his normal form.
|-
|align="center" |[[File:WL4 Wario3.png]]
|align="center" |[[Flaming Wario]]
|Wario after catching fire from a [[Kaentsubo]]. He runs without stopping while the fire spreads but the player can still make Wario jump by pressing {{button|gba|A}}. He runs in the opposite direction when he hits a wall, and any [[Bonfire Block]]s touched turns into ash. Falling into water returns Wario to his normal form.
|-
|align="center" |[[File:WL4 Wario4.png]]
|align="center" |[[Flat Wario]]
|Wario after being crushed by a [[Compressor]]. His body becomes flat light. If he leaves the ground or jumps, he falls back slowly, swaying side to side, just like a feather. He can get into small spaces. Wario can turn back into his normal form by entering a [[Decompressor]].
|-
|align="center" |[[File:WL4 Wario5.png]]
|align="center" |[[Fat Wario]]
|Wario, only fatter. He can turn into this form by eating [[Apple]]s thrown by a [[Ringosukī]]. Wario is invulnerable to enemy attacks, enemies are killed by only touching them. Due to Wario's increased weight he cannot jump high and he walks slow until Wario walks a certain distance. 
|-
|align="center" |[[File:WL4 Wario6.png]]
|align="center" |[[Bubble Wario]]
|Wario after touching an underwater [[bubble]]. He can float upwards until he reaches the surface. This effect is useless unless there is a water current. Wario can access areas that are otherwise inaccessible because the bubble is unaffected by these currents. 
|-
|align="center" |[[File:WL4 Wario7.png]]
|align="center" |[[Snowman Wario]]
|Wario after a mound of snow falls on him from a ceiling. Snow sticks to Wario around his belly area and he is greatly weighed down. Wario turns into a huge snowball and start rolling, breaking any [[Snowman Block]]s that get in his way if he starts walking from a slope. 
|-
|align="center" |[[File:WL4 Wario8.png]]
|align="center" |[[Frozen Wario]] 
|Wario after getting hit by a [[Yeti]]'s sneeze. He becomes immobile and start sliding backwards. The ice breaks once Wario hits a wall or object. 
|-
|align="center" |[[File:WL4 Wario9.png]]
|align="center" |[[Bouncy Wario]]
|Wario when a [[Menhanmā]] strikes him with his hammer. He curls up into a spring and transform into Bouncy Wario. The player is able to make Wario bounce to incredible heights by pressing {{button|gba|A}}. If left alone, the bounce gains power. After jumping, Wario transforms back into his normal form by hitting solid ground.  
|-
|align="center" |[[File:WL4 Wario10.png]]
|align="center" |[[Zombie Wario]]
|Wario when a [[Skeleton Bird]] throws him goo. He moves slow, and jumping above a thin platform causes him to fall through the floor by pressing {{button|gba|A}}, reaching otherwise inaccessible places. Like ''[[Wario Land 3]]'', he is still able to jump, but he cannot jump higher. Wario can transform back by either touching water, or being exposed to bright light.
|-
|align="center" |[[File:WL4 Wario11.png]]
|align="center" |[[Vampire Bat Wario]]
|Wario after being hit by a [[Minicula]]. In this form, Wario takes on the appearance of a Bat, and is able to fly by repeatedly pressing {{button|gba|A}} in order to reach high places. Unlike ''[[Wario Land 3]]'', he cannot transform into an actual vampire. Returning to normal form can be achieved by touching water or being exposed to bright light, like with Zombie Wario.

==Wario's moves==
{{quote2|How 'bout it? You can even do this stuff!|[[Wario]]|[[Wario Land 4]] instruction manual}}

Wario has several different moves in ''Wario Land 4''. Mastering each one of them is essential for progressing in the game.
{|width=100% cellspacing=0 border=1 cellpadding=3 style="border-collapse:collapse;" 
!Image 
!Name
!Description
|-
|align="center" |[[File:WL4-ram.PNG]]
|align="center" |Attack
|Wario can shift his body weight to ram into objects. He can hit the weak spot of [[#Enemies|enemies]] to destroy them, or break blocks to make a path. He also runs a tad faster than normal.
|-
|align="center" |[[File:WL4-S-ram.PNG]]
|align="center" |Dash Attack
|Just like the regular Attack, but with more power. Wario must run for a short distance to build up momentum. Once he does, he runs at terrific speed and is able to break stronger, more solid blocks. 
|-
|align="center" |[[File:WL4-GroundPound.PNG]]
|align="center" |Smash Attack 
|A stronger version of the [[Ground Pound|classic move]] that is mainly used in the [[Mario (franchise)|''Mario'' franchise]] can be used in ''Wario Land 4''. Wario can use it to break blocks below, or defeat enemies.
|-
|align="center" |[[File:WL4-S-GroundPound.PNG]]
|align="center" |Smash Attack (powered)
|Similar to the normal Smash Attack but with more strength. Triggered by continuously ground pounding for a certain amount of time without hitting the ground. Wario can break the more solid blue blocks by performing this move. The move won't cancel until he hits the ground.
|-
|align="center" |[[File:WL4-Roll.PNG]]
|align="center" |Roll
|On a 45º degree slope in the floor, Wario can begin to roll. He can jump while moving, destroy blocks and defeat enemies by using this move. He stops rolling if he either hits something solid or fall into water.
|-
|align="center" |[[File:WL4-Swim.PNG]]
|align="center" |Swim
|Wario is able to swim when he is in a body of water. He can move forward, as well as upward and downward. However, he is unable to swim against water currents.
|-
|align="center" |[[File:WL4-Crawl.PNG]]
|align="center" |Crawl
|When Wario has a small space to squeeze through, he can crawl to pass through. He can also jump while crawling.
|-
|align="center" |[[File:WL4-Throw.PNG]]
|align="center" |Throw
|If Wario picks up an enemy, rock or [[Pinball]], he is able throw it upwards or sidewards. He can also break blocks from a long distance away.

|-
| align="center" rowspan=2 style="background:#D0A0D8" |[[File:WL4-Entry Passage Symbol Artwork.png|70px]]<br>'''[[Entry Passage]]'''
| align="center" style="background:#D0A0D8" |[[File:WL4-Icon01.png]]<br>[[Hall of Hieroglyphs]]
| style="background:#D0A0D8" | The very first level in the game. It consists of a very simple layout, with hieroglyphs of the [[Item Shopkeeper]] on the walls that teach Wario his basic moves. Weak enemies such as [[Marumen]] and [[Spear-Mask]]s appear in this level. In the [[#Game Modes|Normal]] and [[#Game Modes|Hard]] game modes, the [[Switch (Wario Land 4)|switch]] is right at the end of the level (thus making it far easier to reach the [[vortex]] in time). However, in [[#Game Modes|S-Hard]] mode, the Switch is found near the beginning.
|-
| align="center" style="background:#D0A0D8" |[[File:WL4-Icon02.png]]<br>[[Spoiled Rotten]]
| style="background:#D0A0D8" | The boss of the Entry Passage is a purple, eggplant-like creature called Spoiled Rotten. It seems to be quite young, as it carries a blanket and toy doll. Accompanying it are two [[Eggplant Warrior]]s that act as body guards. They behave exactly like [[Totsumen]] and they can be defeated in the same way. Spoiled Rotten is at first defenseless on its own. But after Wario [[#Wario's Moves|ram]]s it a few times, it will reach a point where its health is quite low. Spoiled Rotten will then throw a tantrum, bearing teeth that harm Wario on contact. He will then need to attack from behind. Defeating Spoiled Rotten will grant access to the four main Passages.
|-
| align="center" rowspan=5 style="background:#B8E8B0" |[[File:WL4-Emerald Passage Symbol Artwork.png|70px]]<br>'''[[Emerald Passage]]'''
| align="center" style="background:#B8E8B0" |[[File:WL4-Icon03.png]]<br>[[Palm Tree Paradise]]
| style="background:#B8E8B0" | The first level of the Emerald Passage is very straightforward and of extremely low difficulty. It takes place on a tropical setting with lots of palm trees. [[Marumen]] and [[Spear-Mask]]s in low numbers patrol the grounds of this level. The level's path has no alternate routes for the player to take. The [[Switch (Wario Land 4)|switch]] is at the end, and the player must go back the way they came to reach the [[vortex]]. The level's theme is a shortened version of the [[Karaoke (Medamayaki)|Karaoke]] soundtrack.
|-
| align="center" style="background:#B8E8B0"|[[File:WL4-Icon04.png]]<br>[[Wildflower Fields]]
| style="background:#B8E8B0" | The level Wildflower Fields takes place in a sunny field blossoming with wild flora. Throughout the stage, there are many [[Money Flower]]s that are pollinated by [[Beezley]]s, which will swell and release [[Coin (Wario Land 4)|coins]]. The Beezleys can also sting Wario and transform him into [[Puffy Wario]], which will enable him to reach greater heights in the level. A lot of the level's structure is made up of giant sunflowers, which are hollow so Wario is able to pass through them.
|-
| align="center" style="background:#B8E8B0" |[[File:WL4-Icon05.png]]<br>[[Mystic Lake]]
| style="background:#B8E8B0" | The Mystic Lake is a location of great beauty, with lush grasses and cool lakes. A large part of the level is underwater, where Wario must [[#Wario's Moves|swim]] most of the way. The waters are abundant in [[Goggley-Blade]]s and [[Utsuboankō]], which are enemies that harm Wario. In the mid-way point of the level, a [[Togenobi]] guards the [[Keyzer]], which is essential for progressing to the next level. After hitting the [[Switch (Wario Land 4)|switch]], the upper part of the level is unlocked, which mainly consists of blocks and falling boulders. 
|-
| align="center" style="background:#B8E8B0" |[[File:WL4-Icon06.png]]<br>[[Monsoon Jungle]]
| style="background:#B8E8B0" | The Monsoon Jungle takes place in a swampy setting with lots of water. The water is vastly infested with [[Tobawani]], which will snap at Wario if he swims nearby. Swinging Platforms are in abundance above the water, which are used to allow Wario to safely cross without harm from the Tobawani. However, the swing is often difficult to time and the player may often find themselves falling in the water. After hitting the [[Switch (Wario Land 4)|switch]], Wario will gain access to the underground area of the level, where he will make his final progress before exiting.
|-
| align="center" style="background:#B8E8B0" |[[File:WL4-Icon07.png]]<br>[[Cractus]]
| style="background:#B8E8B0" | The boss of the Emerald Passage is Cractus, a possessed venus flytrap with a huge head that can skewer Wario with its claws and drool a poisonous liquid on him, turning Wario into [[Zombie Wario]]. Wario can deal damage by [[#Wario's Moves|ground pounding]] its head. After taking a certain amount of damage, Cractus will stand upright which will make it harder for Wario to inflict damage on the creature. He will then have to climb a vine above the plant. Defeating Cractus restores the [[Legendary Treasure|Crown]] to the [[Golden Pyramid]].
|-
| align="center" rowspan=5 style="background:#E08080" |[[File:WL4-Ruby Passage Symbol Artwork.png|70px]]<br>'''[[Ruby Passage]]'''
| align="center" style="background:#E08080" |[[File:WL4-Icon08.png]]<br>[[The Curious Factory]]
| style="background:#E08080" | The Curious Factory is a level full of machinery; such as conveyor belts, [[Compressor]]s and [[Decompressor]]s (which will transform Wario into [[Flat Wario]] and back again). Flat Wario can be used to enter tiny places. [[Togerobo]]s make their unique appearance in this level, being a strange creature that has a spiked ball for a head. [[Kaentsubo]]s also make their first appearance here. Hitting the [[Switch (Wario Land 4)|switch]] will open up the underground area of this level, which is much more challenging than the overworld because of the abundance of rotating platforms that Wario will have to cross.
|-
| align="center" style="background:#E08080" |[[File:WL4-Icon09.png]]<br>[[The Toxic Landfill]]
| style="background:#E08080" | The Toxic Landfill is a filthy, polluted level that is mainly made up of toxic water and garbage that take the shape of [[block]]s, which Wario must [[#Wario's Moves|ram]] to destroy and make a path. [[Bow Balloon]]s and [[Ringosukī]] are the main enemies that appear in this level. The arrows of the Bow Balloon will transform Wario into [[Puffy Wario]], and the [[Apple]]s of the [[Ringosukī]] will transform him into [[Fat Wario]]. Both [[#Wario's Reactions|reactions]] are crucial for progressing in the level. After hitting the [[Switch (Wario Land 4)|switch]], Wario must make his way through the underground part of the level to reach the [[vortex]].
|-
| align="center" style="background:#E08080" |[[File:WL4-Icon10.png]]<br>[[40 Below Fridge]]
| style="background:#E08080" | The level 40 Below Fridge, as the name suggests, takes place in a very cold fridge. The level is mainly made up of ice. The snow creature [[Yeti]] are in abundance in this level. They have the ability to transform Wario into [[Frozen Wario]] by sneezing on him. Falling Snow from the ceiling transforms him into Snowman Wario if they land on him. In this form, if Wario walks on a 45° platform, he will start rolling into a snowball and he will be able to break [[Snowman Block]]s. 
|-
| align="center" style="background:#E08080" |[[File:WL4-Icon11.png]]<br>[[Pinball Zone]]
| style="background:#E08080" | Pinball Zone is a funky, colorful and noisy level with many things going on at once. It takes place inside a pinball machine, where the main focus is throwing [[Pinball]]s into slots to break the [[Pinball Block]], which will allow access to the next room. This is the only level to feature the [[Spike Cannon]]s, which is an undefeatable [[#Enemies|enemy]] that shoots spikes at Wario. The level's background displays a new theme in every room. The themes vary from forests, robots, dragons, ect.
|-
| align="center" style="background:#E08080" |[[File:WL4-Icon12.png]]<br>[[Cuckoo Condor]]
| style="background:#E08080" | The boss of the Ruby Passage is Cuckoo Condor, which is what appears to be a giant cuckoo clock. It can grab Wario and shoot gears and electricity at him. After taking a fair amount of damage, the cuckoo clock will fall apart, revealing a giant bird (presumably a condor) within. In this form, Cuckoo Condor can lay eggs that hatch into [[Black Duck|self-destructing chicks]] to damage Wario. Wario can counter this attack by catching and [[#Wario's Moves|throwing]] the eggs at the Condor's head. Defeating Cuckoo Condor restores the [[Legendary Treasure|Earrings]] to the [[Golden Pyramid]].

| align="center" style="background:#F8F098" |[[File:WL4-Icon13.png]]<br>[[Toy Block Tower]]
| style="background:#F8F098" | The first level of the Topaz Passage takes place in a toy castle, with lots of toy blocks found throughout the level. Several unique items appear in this level. There is the [[Triangle Toy Block]] (which Wario must [[#Wario's Moves|throw]] into the slot on a [[Toy Block Door]] to open the door), and the [[Rolling Toy Block]]; which Wario can [[#Wario's Moves|ram]] to move along the ground and use as an object to stand on. The [[Pig Head Statue]] is also unique to this level. It is a pig head that is fixed to a wall in the background. It spits out fire which flares up on the ground below, transforming Wario into [[Flaming Wario]] if he come into contact with it. 
|-
| align="center" style="background:#F8F098" |[[File:WL4-Icon14.png]]<br>[[The Big Board]]
| style="background:#F8F098" | The Big Board is the only level to feature the [[chance wheel]], which is an object with a rotating number counter that Wario can stop by hitting the blue button below the block. When it stops on a certain number, it will have numerous effects such as producing [[Giant Diamond]]s, [[Dice]] and transforming Wario into many of his [[#Wario's Reactions|reactions]]. The very last chance wheel is blue instead of green. It will not disappear after the first hit, but will allow Wario to keep hitting it. This will eventually release the [[Keyzer]]. The level has a general relaxed feel to it. It contains many [[Toy Car]]s, being the main [[#Enemies|enemy]] found here. 
|-
| align="center" style="background:#F8F098" |[[File:WL4-Icon15.png]]<br>[[Doodle Woods]]
| style="background:#F8F098" | The Doodle Woods is a level with a very up-beat feel to it. It is the only level to feature [[Hoggus]], an untouchable [[#Enemies|enemy]] that loves to draw. It has a sketchbook, where it will produce drawings of [[Butatabi]]s and [[Denden]]s which come to life and try to harm Wario. There are also many prominent features of the level related to drawing such as pencils and erasers that act as platforms. Later in the level after the switch has been hit, Wario will come across an area that he must keep climbing upwards. There are several pictures of [[Deburina]]s on the walls that may have been drawn by Hoggus. The pictures will come to life once Wario comes near them.
|-
| align="center" style="background:#F8F098" |[[File:WL4-Icon16.png]]<br>[[Domino Row]]
| style="background:#F8F098" | Domino Row is the only level in the game to feature the use of Dominoes, which are found in increasingly long rows throughout the level. If Wario is to brush past a beginning of a row, they will begin to fall, bringing the ones in front down with it. At the end of the row is a switch. If the dominoes are to reach the switch first, a blue flag with a ''D'' will be raised. However, if Wario is to beat the dominoes to the switch and he hits it first, then a yellow and purple flag will be raised with a ''W'' on it. In result, this will open up a path that would be more convenient for Wario to take, such as shortcuts or paths with more [[Coin (Wario Land 4)|coins]].
|-
| align="center" style="background:#F8F098" |[[File:WL4-Icon17.png]]<br>[[Aerodent]]
| style="background:#F8F098" | The boss of the Topaz Passage is Aerodent, a rat that hides in a giant inflatable teddy bear. It throws down [[Tack Soldiers]], which Wario can [[#Wario's Moves|throw]] to deflate the teddy bear. This will cause it to flip upside down and expose the rodent, its weak spot. Wario can then [[#Wario's Moves|ram]] the rodent to inflict damage. When Aerodent has taken a considerable amount of damage, the Teddy will drop flames which do not harm Wario, but instead transforms him into [[Flaming Wario]]. He will catch fire and run around the screen for a while, wasting valuable time. Defeating Aerodent restores the [[Legendary Treasure|Necklace]] to the [[Golden Pyramid]].

| style="background:#C8D0F8" | Crescent Moon Village takes place in a haunted, moonlit village. The first level of the Sapphire Passage introduces the many ghostly enemies that are native to the horror-themed levels, such as the [[Skeleton Bird]] and [[Men'ono]]. Most of the level takes a straight path, with many blocks and posts as obstacles. A notable enemy appearance in such areas is [[Yūrei]], who, similar to [[Hoggus]], appears in the level's background and cannot be touched. Unlike Hoggus, Yūrei does not harm Wario. Instead, he watches from afar as Wario makes his progress. Whenever Wario defeats an [[#Enemies|enemy]] or breaks a block, [[Coin (Wario Land 4)|coins]] will be produced, which will scatter across the ground. Yūrei's obsession is money, and he will dive and gather up as much money as he can if they are left unattended. Also, once Wario obtains the Keyzer, Yūrei will try and steal it. If he succeeds, Wario will have to chase him to retrieve it, thus wasting valuable time. 
|-
| align="center" style="background:#C8D0F8" |[[File:WL4-Icon19.png]]<br>[[Arabian Night]]
| style="background:#C8D0F8" | Arabian Night is set in an abandoned Arabian village, with Indian-style buildings and unique [[Magic Carpet]]s. Most of the level requires Wario to ride one of these Magic Carpets by jumping, causing the carpet to rise below his feet. [[Mayu Bird]]s are in abundance in the sky's, where they will harm Wario if he is to make contact with their fangs. The level consists of two parts, the indoor and outdoor areas which link to each other via building entrances. While the inside areas are situated in the buildings that Wario can enter, the outside is quite literally everywhere else. Wario can also turn into his zombie form and his [[Vampire Bat Wario|bat form]] in this level.
|-
| align="center" style="background:#C8D0F8" |[[File:WL4-Icon20.png]]<br>[[Fiery Cavern]]
| style="background:#C8D0F8" | Fiery Cavern takes place is an underground cavern with many pools of lava. Wario is able to swim in this lava in the same way as he swims in water, but he will take a great deal of damage. An [[#Enemies|enemy]] that is unique to this level is [[Iwao]], a primate that hurls giant boulders that damage Wario if he happens to be in its path. Wario can only defeat these creature by performing a [[#Wario's Moves|ground pound]] to the head. Wario will come across these creatures in great numbers throughout the first half of the level. In the second half when Wario hits the unavoidable switch, everything in the level will freeze over, including the lava and even the Iwao. In result, Wario is now able to safely travel over the cooled lava (which is now solid ice). The Iwao, when frozen over, quickly thaws and evolves into [[Yeti]]. These creatures have a white coat and always appear to be sneezing, casting icicles that will transform Wario into [[Frozen Wario]].
|-
| align="center" style="background:#C8D0F8" |[[File:WL4-Icon21.png]]<br>[[Hotel Horror]]
| style="background:#C8D0F8" | This level takes place in an old, run down hotel that has multiple floors and many rooms (some are initially locked). Wario enters the level on the first floor, at room 101. Every room in the hotel is accessible, but not always straight through the front door. All rooms link to each other some way or other. Most rooms consists of two floors, so there are two entrances. To the far left of the hotel is a giant bird cage, where a [[Skeleton Bird]] hangs around the area. Wario can access each floor's left side by climbing the steps in the bird cage, but the Skeleton Bird should generally be avoided as it releases a green goo that transforms Wario into [[Zombie Wario]], sending him falling through the floor. Enemies that populate the level's corridors are ghostly creatures such as [[Men'ono]] and [[Minicula]]. When the switch is hit, all doors with a [[Frog Block|frog sign]] on the front will be unlocked.The very last level is very different in terms of gameplay. For starters, the [[switch (Wario Land 4)|switch]] appears at the beginning of the level directly above the [[vortex]], regardless of the [[#Game Modes|game mode]]. This forces Wario to complete the whole level within a [[#List of Time Limits|time limit]]. The whole underground area of this level consists of a river with a strong current that pulls Wario back towards the beginning of the level. In some of the overworld areas, there are places that Wario can fall, thus causing him to travel back to a certain location due to the water's current. The enemies that appear here all first seen in the [[#Sapphire Passage Enemies|Sapphire Passage]]. If the player is to use an [[Wikipedia:Action Replay|Action Replay]] or some other similar hacking device, they can avoid hitting the switch and a hidden theme will play as the [[:File:Unused Wario Land 4 Music Golden Passage.oga|level's true theme]], instead of the [[:File:Wario Land 4 music- Hurry Up!.oga|normal switch music]].
|-
| align="center" style="background:#C8D0F8" |[[File:WL4-Icon22.png]]<br>[[Catbat]]
| style="background:#C8D0F8" | The boss of the Sapphire Passage is Catbat. It is essentially a large, ghostly-like cat with a statue of a bat on his head, which is his weak spot. Catbat has ears that act as bat wings, and likewise it is able to fly during the battle. There is a pool of water below the unstable flooring where a [[Mechanical Fish]] patrols by swimming back and forth. The drill on the creature's head will harm Wario if he is to make contact. Catbat creates waves which must be jumped over. Wario can also balance on top of these moving waves to jump and [[#Wario's Moves|ram]] the bat's weak spot. Once he does so, Catbat will take damage. In retaliation, it will spit out orange and purple spikes, which either damage Wario or turn him into [[Puffy Wario]], respectively. The latter's purpose is to waste time. Defeating Catbat restores the [[Legendary Treasure|Bracelets]] to the [[Golden Pyramid]].

At the beginning of the battle, the [[Black Cat]] is brave enough to confront the Diva. The Golden Diva swallows the feline whole and Wario is left to battle by himsellf. The Golden Diva has several different attacks, much more than previous bosses. She begins by hiding her face behind her fan. Wario will have to throw ghostly heads at her. Then she will cast several different enemies, one at a time, in an attempt to harm Wario. They are the [[Green Enemy]] (which Wario can [[#Wario's Moves|throw]]), the [[Big Ball]] (he must [[#Wario's Moves|ram]]), the [[Black Duck]] (also throw), and the [[Tonkachi‎]], which he must throw up in the air so it lands back on top of him, transforming him into [[Bouncy Wario]]. He must then throw himself upward to strike the Diva, and thus damaging her. A few sequences of these enemies will bring the Golden Diva to a low point in her HP. She then unleashes her final phase, where her head grows to a fearsome size and she starts destroying the ground. Wario must [[#Wario's Moves|ram]] the side of her head to bring her to the last few points of HP. On the very last point, simply none but her [[Diva's Lips|Lips]] will remain. A simple attack to these Lips will free the swallowed Black Cat. The ending cutscene follows.

==Allies==
Within the [[Golden Pyramid]], there are a few characters who are willing to help Wario. They all have different purposes and their personalities and traits may differ, but they all have the same goal; to rid the Pyramid of the money crazed [[Golden Diva]] and to restore it to its former glory.

==Bosses==
Each of the six bosses guards a different Passage in the Pyramid. [[Item Shop (Wario Land 4)|Items]] can be purchased with [[Frog Medal]]s to weaken bosses at the battle's beginning.

Spoiled Rotten is, at first, defenseless on its own. But after Wario damages it a few times, it reaches a point where its health is quite low. Spoiled Rotten then throws a temper-tantrum, bearing teeth that harm Wario on contact. Wario hurts it by attacking it from behind. Defeating Spoiled Rotten grants access to the four main Passages.

==Enemies and other characters==
{{quote2|Taking care of most of my enemies is easier than taking candy from babies – which I highly recommend, by the way!!|[[Wario]]|[[Wario Land 4]] instruction manual}}

During his adventure, Wario encounters more than three dozen kinds of enemies. While some can be found in more than one passage, many enemies are only unique to a certain passage. The enemy's characteristics usually go by the passage theme. Each enemy also drops an assigned value of [[Coin (Wario Land 4)|Coins]].

*An asterisk (*) next to the enemy name signifies that they transform Wario in some way.
*''N/A'' under "Coins dropped" signifies that the enemy cannot be defeated.

===Common enemies===
The following enemies may be found in multiple passages. No enemy appears in all six passages.

==Reception==
The game received generally positive reviews. The <i>"portable masterpiece"</i> received praise and excellent review scores on its [[List of Wario Land 4 media|soundtrack]], collectibles throughout the game and its general thrill of satisfaction. One gaming website commented about even on its ten year anniversary, it <i>"still remains the best portable ''Mario'' game to date"</i>.<ref>[http://www.1up.com/features/wario-land-4-remains-best-portable-mario Why Wario Land 4 remains the best portable Mario game]</ref> [[Wikipedia:IGN|IGN]] gave ''Wario Land 4'' a nine out of ten, or "Outstanding", citing its well thought out level design and replayability, and how the game <i>"puts a lot more emphasis on action"</i> compared to its [[Wario Land (series)|predecessors]].<ref>[http://au.gameboy.ign.com/articles/165/165422p1.html IGN Wario Land 4 review]</ref> Praise was also given to how much attention the developers paid to the sounds and music. It was not given a full ten because the game does not necessarily push the performance power of the Game Boy Advance in regards to animation design. The website quoted that <i>"it's a little disappointing to see that Wario isn't much of a step beyond his [[Game Boy Color|GBC]] adventure in terms of art and animation...other than the sprite effects, it could have been done on the 8-bit handheld"</i>.

''Wario Land 4'' was first announced at [[Wikipedia:Electronic Entertainment Expo|E3]] 2001. The first released screenshots were very different from the final game. Wario had a darker, more orange skin tone. A lot of the enemies were also shown to have a different color scheme. A notable difference from the final game is how Wario originally had a [[Garlic]] meter, serving as a replacement for the heart gauge below the heart meter. The [[Mini-Game Shop]] was going to be called the Game Corner, and Wario originally needed a [[Key]] to unlock a [[Jewel Piece Box]].

==Quotes==
{{main|List of Wario Land 4 quotes}}
In ''Wario Land 4'', there is not a large amount of quotes within the game itself. But there are many notable quotes within the game's instruction manual, where Wario describes to the reader many aspects of gameplay and a few [[#Enemies|enemy]] descriptions. Some of the most notable are shown below.

Quotes found in the game;
*''"[[Golden Pyramid|Legendary Pyramid]] discovered deep in Jungle!! [[Legendary Treasure]] nearly found, but accidents hindered findings."'' &ndash; [[:File:WL4-newspaper.PNG|Newspaper article]] seen in the game's opening cutscene.
*''"Welcome to the [[Item Shop (Wario Land 4)|Item Shop]]."'' &ndash; The [[Item Shopkeeper]] welcoming Wario to the Item Shop.
*''"Oh no, no! Hurry up!"'' &ndash; Wario, when he hits the [[Switch (Wario Land 4)|switch]] in a [[#Passages|level]].

Quotes found in the game's manual;
*''"I ain’t normal! And I don’t mean that I’m stupid! I can do aaalllll kinds o’ stuff that normal humans can’t, you know what I mean? How ‘bout that? Amazing, huh?"'' &ndash; Wario informs the reader of his skills.
*''"Rumour has it that no one who’s entered the [[Golden Passage]] have ever come out alive! Scary!"''&ndash; Wario warning the player of the dangers found in the Golden Passage. 
*''"Yeahhhhh, that’s ME!!! More gorgeous than any Hollywood star! Get a good look at me while you can!!"'' &ndash; Wario describing himself. 
*''"I don’t always speak so crudely, you know. I’m just worried about you because you play so badly!! Why do I care? Because I’m the one that feels it when you screw up, that’s why!!! So just try to get better at this game, OK?! I’m begging you!"'' &ndash; Wario, worried that the player will lead Wario into some danger.
*''"Haven’t you kids ever done something that made you look stupid? Oh, is that right? Well, FINE then! But even the powerful Wario gets into some embarrassing situations in this game! I eat too much and get [[Fat Wario|all chubby]], a bee stings my face and makes it [[Puffy Wario|swell like a balloon]], my body [[Flaming Wario|catches fire]], and all kinds of other bad things happen to me!! But I’m a tough guy, so I keep coming back for more! You wimps could learn something from me!"'' &ndash; Wario gives examples of his tough times.

==Trivia==
*Part of the vocals used in the game's title track were taken from the first track of [[Wikipedia:Zero-G Ltd|Zero-G]]'s ''Vocal XTC'' audio sample compilation. The specific vocal lines in question are ''"Your time is over, I've had enough! Here I come! Look out, here I come!"'', sung by British session singer Helen Binding.<ref>[http://www.zero-g.co.uk/store/vocal-xtc-wav-acid-p431.php Zero-G ''Vocal XTC'' product page] (accessed on September 24, 2016)</ref><ref>[http://www.zero-g.name/CD_Booklets/Vocal_XTC_CD_Booklet.pdf ''Vocal XTC'' CD booklet] (accessed on September 24, 2016)</ref>
