'''''Super Mario Bros. 2''''' is the second game in the ''[[Super Mario (series)|Super Mario]]'' series outside Japan and the third entry overall.<ref name=encyclopedia>Kazuya Sakai (Ambit), kikai, Akinori Sao, Junko Fukuda, Kunio Takayama, and Ko Nakahara ({{wp|Shogakukan}}) (ed.). ''[[Super Mario Bros. Encyclopedia|Encyclopedia Super Mario Bros.]]'' Milwaulkie: [[Dark Horse Comics|Dark Horse Books]], 2018. ISBN: 978-4-09-106569-8.</ref> It is a 2D [[Genre#Platform games|platform game]] originally released for the [[Nintendo Entertainment System]] in North America in 1988. In the years that followed, it has been ported to many other systems, including a release on the [[Wii]]'s [[Virtual Console#Wii|Virtual Console]] in 2007, the [[Nintendo 3DS]]'s [[Virtual Console#Nintendo 3DS|Virtual Console]] in 2012, and the [[Wii U]]'s [[Virtual Console#Wii U|Virtual Console]] in 2013. As a result of Japan already having a ''Super Mario Bros. 2'' (known in English as ''[[Super Mario Bros.: The Lost Levels]]'' and ''[[Super Mario Bros. Deluxe#Super Mario Bros. for Super Players|Super Mario Bros. for Super Players]]''), the game did not make its debut in the country until after the release of ''[[Super Mario World]]'', on September 14, 1992, making it Japan's fifth installment of the series.

''Super Mario Bros. 2'' came about after [[Nintendo]] of America deemed ''Super Mario Bros.: The Lost Levels'' too difficult for Western audiences,<ref>McLaughlin, Rus. (September 13, 2010) [https://www.ign.com/articles/2010/09/14/ign-presents-the-history-of-super-mario-bros?page=3 IGN Presents: The History of ''Super Mario Bros.''] ''IGN''. Retrieved August 2, 2017.</ref> which led Nintendo to redevelop the [[Family Computer Disk System]] game ''[[Yume Kōjō: Doki Doki Panic]]'' into a ''Super Mario Bros.'' game for the international release. After its release, the game became a commercial success, and eventually the game became well received enough that it was also released in Japan. After performing well both critically and commercially, ''Super Mario Bros. 2'' has been rereleased as one of the four games featured in ''[[Super Mario All-Stars]]'', as well as having its own [[reissue|remake]] in ''[[Super Mario Advance]]''. Many enemies introduced in ''Super Mario Bros. 2'' have become common recurring enemies in the ''[[Super Mario (franchise)|Super Mario]]'' franchise, such as [[Bob-omb]]s, [[Pokey]]s, [[Shy Guy]]s, and more, while the gameplay mechanic of picking up various items and tossing them has been reused in several later games.

When Mario opened a door after climbing a long stair in his dream, another world spread before him and he heard a (faint)<ref>[https://themushroomkingdom.net/smb2_proto.shtml ''Super Mario Bros. 2'' Prototype - The Mushroom Kingdom]</ref> voice call for help to be freed from a spell.

There are seven worlds in this game. The first six has three levels apiece, and the seventh has two. At the end of each world, the player encounters one boss. [[Mouser]] is encountered at the end of World 1, [[Tryclyde]] in World 2, Mouser again in World 3, [[Fryguy]] in World 4, [[Clawgrip]] in World 5, Tryclyde again in World 6, and Wart himself at the end of World 7.

|align="center"|{{nowrap|[[Mask Gate]]}}<br>[[File:SMB2 Mask Gate sprite.png]][[File:SMB2 Mask Gate sprite 2.png]]

|Found at the end of each level (or, in boss levels, just before the boss room), Mask Gates will open once the level's Crystal Ball (which is either dropped by Birdo or found out in the open) has been picked up. When entered, the level ends (or, in boss levels, the boss room is entered).

===Enemies===

{|class=wikitable width=80%

|align="center"|[[Albatoss]]<br>[[File:Albatoss SMB2 Sprite.png]]

|Albatosses fly only horizontally. They can drop Bob-Ombs on players, but they can also be ridden. Unlike other enemies, they cannot be picked up, but they are defeated as with any other enemy.

|align="center"|[[Autobomb]]<br>[[File:Autobomb SMB2 Sprite.png]]

|Shyguys often ride Autobombs. Autobombs shoot projectiles, but if the Shyguy is removed, they simply move. Players can ride on Autobombs, but Autobombs must be destroyed with an item.

|align="center"|[[Beezo]]<br>[[File:SMB2 Red Beezo Sprite.png]]

|Beezos fly down and attempt to run into the player with their bidents. Players can jump on them and pick them up.

|align="center"|[[Bob-omb|Bob-Omb]]<br>[[File:Original Bomb.png]]

|Bob-Ombs run back and forth and eventually self-destruct if they are near a player. If they self-destruct, they can harm players. Players can pick them up and throw them.

|align="center"|[[Cobrat]]<br>[[File:Cobrat SMB2 Sprite.png]]

|Cobrats are seen roaming on the ground, but they can also hide in jars. If they spot a player, they may jump and shoot a single projectile. Cobrats can be picked up and thrown.

|align="center"|[[Flurry]]<br>[[File:Flurry SMB2 Sprite.png]]

|Flurries are found only in ice levels. Here, they attempt to run into the player. They move faster than average, but they are prone to slipping.

|align="center"|[[Hoopster]]<br>[[File:Hoopster SMB2 Sprite.png]]

|Hoopsters crawl slowly on vines or trees aimlessly, speeding up whenever descending. They harm players if they make contact with them from above or the side. Players can jump on and ride them like an elevator, and even pick them up and throw them.

|align="center"|[[Ninji]]<br>[[File:Ninji SMB2 Sprite.png]]

|Some Ninjis are stationary enemies that simply jump while others charge and jump into the player. They can be picked up and thrown.

|align="center"|[[Ostro]]<br>[[File:Ostro SMB2 Sprite.png]]

|Ostros are often seen being ridden by Shyguys. If the Shyguy is removed, they travel in a straight line. They can be picked up and thrown, but they do not bounce off enemies.

|align="center"|[[Panser]]<br>[[File:Panser SMB2 Sprite.png]]

|Pansers shoot fireballs at the player. Red varieties are stationary and shoot three fireballs. The green/gray variety patrols and shoot fireballs straight up. Pink varieties chase the player and shoot three fireballs.

|align="center"|[[Phanto]]<br>[[File:Madmask.png]]

|Phantos are normally dormant enemies, but if players pick up a key, they attempt to fly into the player. If the player drops or uses the key, they deactivate. They cannot be picked up and there are limited methods to destroy them.

|align="center"|[[Pidgit]]<br>[[File:Pidgit SMB2 Sprite.png]]

|Pidgits are always seen on carpets. Pidgits attempt to dive bomb into the player, but players can jump on them, pick them up, and throw them. Once the Pidgit has been removed, players can ride the carpet and control it for a brief amount of time.

|align="center"|[[Pokey]]<br>[[File:Pokey SMB2 Sprite.png]]

|Pokeys attack players by moving slowly into them. Pokeys can be various heights. They can be defeated by having objects thrown at them or their body segments being removed one by one.

|align="center"|[[Porcupo]]<br>[[File:Porcupo SMB2 Sprite.png]]

|Porcupos cannot be jumped on, so to defeat them, players must throw an object at them.

|align="center"|[[Shy Guy|Shyguy]]<br>[[File:SMB2 Red Shyguy Sprite.png]]

|The basic enemies of the game, Shyguys walk back and forth, harming the player if they run into them. They can be picked up and thrown. Red Shyguys walk off cliffs while pink Shyguys turn at the ledges.

|align="center"|[[Small Fry Guy]]<br>[[File:Small Fry Guy NES.png]]

|Small versions of Fryguy that bounce in the player's direction. They appear when Fryguy is defeated. They cannot be picked up or thrown, and must have an item thrown at them to be defeated.  

|align="center"|[[Snifit]]<br>[[File:Snifit SMB2.png]][[File:Snifit SMB2 Sprite.png]]

|Snifits shoot projectiles at players, but they act similar to Shyguys. Gray/green Snifits jump and fire projectiles while the other variants walk. The pink Snifit turns around at ledges while a singular red Snifit in [[World 3-3 (Super Mario Bros. 2)|World 3-3]] walks off ledges.

|align="center"|[[Spark]]<br>[[File:Spark SMB2 Sprite.png]]

|Sparks circle around platforms or hover in the air. Sparks can harm the player if they touch them.

|align="center"|[[Trouter]]<br>[[File:Trouter SMB2 Sprite.png]]

|Trouters jump from below and fall back. Players can use them as platforms to jump across gaps, but Trouters can harm players if players touch them at the sides.

|align="center"|[[Tweeter]]<br>[[File:Tweeter.png]]

|Tweeters, although they have wings, are found hopping across the ground. They can be picked up and thrown.

|align="center"|[[Whale]]<br>[[File:Whale SMB2 Sprite.png]]

|Not typical enemies, whales serve generally as platforms. Their bodies and their tails can be jumped on. Their waterspouts can also carry players, but the waterspouts can harm players if players touch them at the sides.

====Mini-bosses====

{|class=wikitable width=80%

|align="center"|[[Birdo]]<br>[[File:SMB2BirdoSprite.png]][[File:Birdo Red SMB2 Sprite.png]]<br>[[File:Birdo Gray SMB2 Sprite.png]][[File:Birdo Green SMB2 Sprite.png]]

|Birdo is a recurring mini-boss, appearing at the end of every first and second level in the worlds. Birdo comes in three varieties. The pink one shoots simply eggs, which can be picked up and thrown at it. The red one shoots randomly eggs or fireballs (which harms players if they touch them). The remaining type appears green or gray depending on location (but are assigned to the same palette) and shoots only fireballs; these ones must be defeated with [[Mushroom Block]]s.

====Bosses====

{|class=wikitable width=80%

!Image

|align="center"|[[Mouser]]<br>[[File:SMB2 Gray Mouser Sprite.png]][[File:Mouser Green NES.png]]

|Mouser is the first true boss players encounter. He attacks by throwing bombs. The bombs sit for a while before they explode, enabling players to pick them up and throw them at Mouser. If the bomb explodes on Mouser, he takes damage. There are two variants of Mouser: one with pink ears and one with green ears. A {{media link|DDP Albino Mouser.png|white and red variant}} was replaced by Clawgrip when ''Yume Kōjō: Doki Doki Panic'' was remade into ''Super Mario Bros. 2''.

|align="center"|[[Tryclyde]]<br>[[File:Tryclyde SMB2 NES sprite.png]]

|Tryclyde shoots a series of fireballs that harms the player if the player touches them. Players must throw several Mushroom Blocks at Tryclyde to defeat him.

|align="center"|[[Fryguy]]<br>[[File:Fryguy SMB2 Sprite.png]]

|Fryguy shoots fireballs at players. Players must throw Mushroom Blocks at him to damage him. Once he takes enough damage, he bursts into [[Small Fry Guy]]s. These take one hit from a Mushroom Block to be defeated, and destroying these enemies clears the level.

|align="center"|[[Clawgrip]]<br>[[File:Clawgrip SMB2 Sprite.png]]

|Clawgrip throws rocks at players. These rocks can be picked up and tossed at Clawgrip, inflicting damage on him. Once he is hit five times, he is defeated.

|align="center"|{{nowrap|[[Mask Gate]]}}<br>[[File:SMB2 Mask Gate sprite 3.png]]

|Although most Mask Gates are harmless and allow completion to the level, the Mask Gate within the dream factory is aggressive, attacking the players by flying into them. Players must attack it with [[Mushroom Block]]s to stun it for a short period. Once it is stunned, it allows entry into Wart's room.

|align="center"|[[Wart]]<br>[[File:Wart SMB2 Sprite.png]]

|Wart is the final boss of the game. He moves back and forth and shoots harmful bubbles at the player. A [[Dream Machine|machine]] nearby spawns vegetables. To defeat Wart, players must throw these vegetables at Wart when Wart's mouth is open. Wart takes six hits to defeat.

{|class=wikitable width=80%

!Image

|align="center"|[[1-Up Mushroom|1 UP]]<br>[[File:SMB2 1-Up Mushroom Sprite.png]]

|When players collect this item, they receive an extra life.

|align="center"|[[Bomb]]<br>[[File:Bomb SMB2 Sprite.png]]

|Bombs can be found normally, from plucking vegetables, or from Mouser. They eventually explode, destroying [[brick wall]]s as well as harming nearby enemies and players.

|align="center"|[[Brick wall]]<br>[[File:Brick wall SMB2 NES.png]]

|Brick walls can be destroyed by explosions created by bombs and [[Bob-omb]]s, which is often necessary to progress.

|align="center"|[[Cherry]]<br>[[File:SMB2 Cherry Sprite.png]]

|Found scattered throughout levels, cherries can be collected. If players collect five, a [[Super Star|Starman]] appears.

|align="center"|[[Coin]]<br>[[File:CoinSMB2.png]]

|Coins are found only in [[Subspace|Sub-space]]. When players pluck vegetables, they receive coins. Coins are used in the [[Bonus Chance]] at the end of a level for extra lives.

|align="center"|[[Crystal Ball]]<br>[[File:Crystal Ball SMB2 Sprite.png]]

|Found at the end of the level or by defeating Birdo, Crystal Balls enable the Mask Gate to open so players can complete the level.

|align="center"|[[Dream Machine]]<br>[[File:Dream_Machine_SMB2_sprite.png]]

|A machine belonging to the Subcons, which produces the dreams that form the land of Subcon itself. In stealing it, Wart is able to force it into producing minions for his cause. During the battle with Wart, it creates Vegetables, Wart's weakness, for the player to use against him.

|align="center"|[[Birdo's Egg|Egg]]<br>[[File:Birdo Egg SMB2 Sprite.png]]

|Pink Birdos always spit out eggs, while Red Birdos sometimes spit out eggs (and sometimes spit out fireballs instead). Players can pick these eggs up as they travel through the air, then throw them at Birdo to inflict damage on it.

|align="center"|[[Magic carpet|Flying carpet]]<br>[[File:Magic Carpet SMB2 Sprite.png]]

|After Pidgits are defeated, players can ride and control their Magic Carpets for a short time.

|align="center"|[[Grass]]<br>[[File:SMB2 Red Grass Tuft.png]]

|The player can pull tufts of grass to reveal objects, mainly vegetables.

|align="center"|[[Jar]]<br>[[File:Vase SMB2 Sprite.png]]

|Jars, as with [[Warp Pipe]]s, can be entered by ducking. Jars contain usually some items, including POWs, Turtle Shells, and keys. Jars also contain some enemies, such as Shyguys.

|align="center"|[[Key]]<br>[[File:Key SMB2 Sprite.png]]

|Keys open locked doors, granting access to another part of the level. Phantos guard it, however.

|align="center"|[[Magical Potion|Magic Potion]]<br>[[File:Magic Potion SMB2 Sprite.png]]

|Found after being plucked, a Magic Potion creates a door depending where the player tosses them. This door leads to Sub-space.

|align="center"|[[Mushroom]]<br>[[File:Mushroom smb2.png]]

|Found only in certain spots of Sub-space, Mushrooms give an extra vitality point once they are picked up. This vitality remains for the rest of the level. The Mushroom also restores any lost health.

|align="center"|[[Mushroom Block]]<br>[[File:MushroomBlock1.png]][[File:MushroomBlock2.png]][[File:MushroomBlock3.png]]<br>[[File:MushroomBlock4.png]][[File:MushroomBlock5.png]]

|Mushroom Blocks are simple throwing items. They can be used as weapons or get stacked so players can reach higher places. Mushroom Block designs vary from world to world; the first design is used in Worlds 1 and 3 in all versions (and World 5 in the SNES and GBA versions), the second design is used in Worlds 2 and 6, the third design is used in World 4, the fourth design is used in World 5 exclusively in the NES version, and the fifth design is used in World 7.

|align="center"|[[POW Block|POW]]<br>[[File:POW Block SMB2 Sprite.png]]

|POWs can be thrown to create a powerful quake. This quake defeats most enemies in the screen.

|align="center"|[[Rocket]]<br>[[File:Rocket SMB2 Sprite.png]]

|Rockets are found in grass. If a rocket is found, it automatically transports players to the next part of the level.

|align="center"|[[Small heart]]<br>[[File:Small Heart SMB2 Sprite.png]]

|For every eight enemies defeated, a small heart appears. Small hearts restore any HP a player has lost. If the player is in [[Small Mario|small form]], the heart grows the player to [[Super Mario (form)|Super form]].

|align="center"|[[Super Star|Starman]]<br>[[File:Starman SMB2 Sprite.png]]

|A Starman appears after players collect five cherries. Once players have collected a Starman, they become invincible for a short amount of time, enabling them to defeat most enemies that they touch.

|align="center"|[[Stop Watch]]<br>[[File:Stopwatch SMB2 Sprite.png]]

|Found by plucking four ripened vegetables from the grass, then plucking what would otherwise be a fifth, the Stop Watch stops all enemy movements for a brief time.

|align="center"|[[Red Shell|Turtle Shell]]<br>[[File:Red Shell SMB2 Sprite.png]]

|Turtle Shells are found in grass. Once they are thrown, they slide across the ground, defeating any enemy it touches. Once it hits a wall, it is destroyed. If players attempt to land on the shell, they can ride on it.

|align="center"|[[Vegetable]]<br>[[File:SMB2 Sprout 1.png]][[File:SMB2 Sprout 2.png]][[File:SMB2 Sprout 3.png]][[File:SMB2 Sprout 4.png]][[File:SMB2 Veggie 1.png]][[File:SMB2 Veggie 2.png]][[File:SMB2 Veggie 3.png]][[File:SMB2 Veggie 4.png]][[File:SMB2 Veggie 5.png]][[File:SMB2 Veggie 6.png]]

|The basic weapon in the game, vegetables are plucked from grass tufts and can be thrown at enemies to defeat them. Vegetables bounce after they hit an enemy, which can lead to consecutive hits on enemies. If one vegetable defeats enough enemies, extra lives may be rewarded. While unripened vegetables (Sprouts) have no additional effects, plucking four fully ripened vegetables, then going to pluck a fifth, will instead result in the player plucking a Stop Watch.

''Super Mario Bros. 2'' started out as a prototype ''Super Mario''-style platform game developed by Kensuke Tanabe, a developer for Nintendo. The prototype game emphasized vertically scrolling levels and throwing blocks. It was originally intended to be a two player co-op game, allowing players to toss each other around. However, the technical limitations of the Nintendo Entertainment System made it difficult to produce a polished game with these elements. It was decided to add more Mario-like elements, such as horizontal levels (although many vertically oriented levels were retained in the final project).<ref>[https://www.wired.com/2011/04/super-mario-bros-2/ The Secret History of ''Super Mario Bros. 2'', Wired.com]</ref> Some time later, the {{wp|Fuji Television}} Company requested that Nintendo create a video game using Yume Kōjō mascots, and Tanabe developed the prototype into ''[[Yume Kōjō: Doki Doki Panic]]'', which became one of the best-selling games for the [[Family Computer Disk System]].

*The NES version of the game was released on the Wii [[Virtual Console#Wii|Virtual Console]] for 500 points in 2007.

*The NES version of the game was released for the Wii U [[Virtual Console#Wii U|Virtual Console]] in 2013.  

Additionally, at least three versions of the North American manual exist. One version provides the full description of Birdo ("Ostro") as "''He thinks he is a girl and he spits eggs from his mouth. He'd rather be called "birdetta."''{{sic}},<ref>[https://www.digitpress.com/library/manuals/nes/Super%20Mario%20Bros%202.pdf ''Super Mario Bros. 2'' instruction booklet] PDF scan available on digitpress.com.

The NES ''Super Mario Bros. 2'' manual reuses enemy sprites and artwork from the ''Yume Kōjō: Doki Doki Panic'' manual (with the notable exception of the [[Pokey]] artwork, as well as the omission of a gray Shyguy and addition of [[Tweeter]], [[Flurry]], [[Spark]], and [[Clawgrip]]<ref name="DDP"/>). Thus, it uses the designs of [[Albatoss]] and [[Phanto]] from ''Yume Kōjō: Doki Doki Panic''.<ref>[https://www.digitpress.com/library/manuals/nes/Super%20Mario%20Bros%202.pdf ''Super Mario Bros. 2'' instruction booklet, pages 24-25.]</ref>

During the ending celebration sequence in the NES version, there are common mistakes in the number of levels each hero completes.

In the game's prototype, there is a different color palette for the in-game title, which includes tans and oranges, which contrasts with the final version's reds and blues. Princess Toadstool is shown to have more hair. Characters need to use a [[Magic Lamp]] to access [[Subspace|Sub-space]], similar to ''Yume Kōjō: Doki Doki Panic''. The characters also lack the whites of their eyes and the ability to run.

''Super Mario Bros. 2'' has been received positively, with IGN editor Lucas Thomas praising the graphics, sound and replay value,<ref>[http://wii.ign.com/articles/801/801793p1.html ''Super Mario Bros. 2'' Review - Wii Review at IGN]</ref> although he insisted that Western gamers could have gotten into the Japanese version of the game. GameSpot critic Alex Navarro agreed, and commented that the game "...shows that veering from the beaten path of a franchise's standard game design isn't always a bad idea".<ref>[https://www.gamespot.com/reviews/super-mario-bros-2-review/1900-6173644/ ''Super Mario Bros. 2'' Review for Wii - GameSpot]</ref>

*''[[zeldawiki:The Legend of Zelda (Game)|The Legend of Zelda]]'': The sound effect of Birdo spitting an egg is taken from the sound effect that plays when a magic projectile is fired from [[Link]] holding the [[zeldawiki:Fire Rod|Fire Rod]] or from a [[zeldawiki:Wizzrobe|Wizzrobe]].<ref>https://youtube.com/watch?v=shPepPVugos=27s</ref>

*''[[Wario's Woods]]'': Toad's strength returns in this game, and he picks up, carries, and throws Bombs and his enemies as he did in ''Super Mario Bros. 2''. Some enemies (such as the [[Spud]]) also vaguely resemble the vegetables from ''Super Mario Bros. 2''. Birdo also makes her first reappearance in the ''Super Mario'' franchise through this game.

*''[[Super Smash Bros. Brawl]]'': Peach retains her moveset from ''Melee'', and there's another trophy of Birdo. Also, Wart and Birdo's names appear in the random name selection. Finally, ''Super Mario Bros. 2'' is available as a [[Masterpiece]] to play. The character the trial starts out with is Peach (but it is possible to play as another character if one gets a Game Over before the trial ends). Snifit and Mouser appear as stickers. To unlock it, one must win five brawls with Peach.

*''[[Donkey Kong Country: Tropical Freeze]]'': The ability to pluck items out of the ground (using [[Item Handle]]s) and the ability to carry specific enemies were brought over from ''Super Mario Bros. 2'', according to [[Kensuke Tanabe]].<ref>''Nintendo''.

*''[[Super Mario Bros. Wonder]]'': The [[Crouching High Jump|Power Squat Jump]] move reappears as the Crouching High Jump badge, and Luigi's high jump and [[Scuttle]] return as the Floating High Jump badge. Peach's [[Floating Jump]] returns as another badge.

*On the [[Nintendo Entertainment System]] / [[Family Computer|Famicom]], all sprites are limited to three colors per sprite. Despite this, [[Mario]], Luigi and [[Princess Peach|Princess Toadstool]] have white in their eyes along with three additional colors. This effect is achieved by a white rectangle hidden behind the character's sprite, while the eyes are transparent. This is part of the reason why their eyes flicker when entering a door or overlapping with another sprite.<ref>Retro Game Mechanics Explained (November 3, 2020).
