'''''Mario & Luigi: Partners in Time''''' ('''''Mario & Luigi RPG 2×2''''' in Japan) is a turn-based action [[Genre#Role Playing|RPG]] video game for the [[Nintendo DS]], developed by [[AlphaDream]] and published by [[Nintendo]], and it is the second title in the [[Mario & Luigi (series)|''Mario & Luigi'' series]]. The story of the game involves [[Mario]] and [[Luigi]], time-traveling between their present and past times, and teaming up with their infant selves, [[Baby Mario]] and [[Baby Luigi]], to stop the invasion in the past by the enemy alien species called the [[Shroob]]s. The English and Spanish names of this game are puns on the title of the short story compilation ''[[wikipedia:Partners in Crime (short story collection)|Partners in Crime]]''.

Though the game is primarily a turn-based RPG, the game mixes in action RPG and platformer elements, which is the primary gameplay point of the ''Mario & Luigi'' series. The game takes many elements from the first game, ''[[Mario & Luigi: Superstar Saga]]'', and revamps it to take advantage of the [[Nintendo DS]]'s new features. While it makes almost no attempt to use the touch screen ([[Mario]] must rub the dirt off of [[Toadbert's Drawing|a drawing]] at one point), the game uses the addition of the {{button|ds|X}} and {{button|ds|Y}} buttons, the extra screen, and greater system resources.

Like its predecessor, it is one of the few ''[[Mario (franchise)|Mario]]'' games to have been released in North America before Japan. However, the game was re-released in the [[Wii U]] [[Nintendo eShop]] in Japan first.

==Story==
[[File:Shroob World M&L.png|thumb|150px|left|The planet where the [[Shroob]]s live.]]
During Mario and Luigi's infancies, [[Shroob]]s from a withering [[Shroob Planet|distant planet]] find the [[Mushroom Kingdom]] and invade it. The invasion forces [[Baby Mario]], [[Baby Luigi]], [[Baby Peach]], [[Toadsworth the Younger]], and [[Baby Bowser]] (who had been attempting to capture Baby Peach at the time) to flee in the [[Koopa Cruiser]].

In the future, [[Princess Peach]], [[Toadiko]], and [[Toadbert]] travel to the past via [[Professor E. Gadd]]'s [[E. Gadd's Time Machine|time machine]], which is powered by the [[Cobalt Star]]. But when the device returns, it is occupied by [[Junior Shrooboid|a hostile alien]], forcing Mario and Luigi to use a newly-formed [[time hole]] in the [[Princess Peach's Castle|castle]] gardens to go to the past and find Peach. Before they proceed to [[Hollijolli Village]], they receive [[Stuffwell]], a talking suitcase made by E. Gadd, to assist them and help them carry supplies on their quest. Upon their arrival in Hollijolli Village, they are attacked and defeated by a trio of [[Shroob]]s, but [[Baby Mario]] and [[Baby Luigi]] arrive and save their adult selves soon afterward. The adult Mario Bros. join the rest on the [[Koopa Cruiser]], but the cruiser is attacked by [[Princess Shroob]], the leader of the Shroobs, and crashes into [[Bowser's Castle|Baby Bowser's Castle]] where Mario, Luigi, Baby Mario, and Baby Luigi find a Cobalt Star Shard. They travel through another time hole to the present day Princess Peach's Castle with Toadsworth and Baby Peach, who they leave behind as they return to the past through a new time hole opened by the Cobalt Shard.

The time hole leads to [[Toadwood Forest]], where the group finds a weakened Toadiko wrapped in a tree's branches. She manages to tell them that the Shroobs have kidnapped Peach before the tree sucks away the last of her [[vim]]. Shroob UFOs then attack and fire at Toadiko and she turns into a [[Shroob Mushroom]], which the aliens use to fuel their ships. The Mario Bros. travel to the Shroobs' [[Vim Factory]] to shut down the operation. The babies receive [[hammer]]s after they defeat the [[Hammer Bro (Mario & Luigi: Partners in Time)|Hammer Bros.]] and when the protagonists defeat the [[Swiggler]], they briefly obtain a second [[Cobalt Shard]] before [[Baby Bowser]] steals both shards and [[Kamek]] picks him up and they flee.

[[File:Toadwood Forest MLPiT.png|thumb|150px|The four heroes solve puzzles in [[Toadwood Forest]].]]
After a brief stop in Peach's Castle of the present and learning the [[Spin Jump|Toadsworth Twist]], the protagonists use another time hole to travel to [[Yoshi's Island (place)|Yoshi's Island]] of the past, where all the Yoshis have disappeared. They find Kamek and follow him back to Baby Bowser; Kamek attacks them but is defeated and they chase after Baby Bowser, who swallows the Cobalt Shards when they corner him. All of them are then eaten by a massive Shroobified Yoshi monster, [[Yoob]]. Inside Yoob, they find the missing Yoshis and an amnesiac Toadbert, who is carrying a partly obscured drawing that he made of what happened during the battle between Peach and Princess Shroob. After the Mario Bros. and their baby counterparts defeat [[Sunnycide]], an egg monster, everyone escapes Yoob, including Baby Bowser, who coughs up the Cobalt Shards later on after choking on the last remaining Yoshi Cookies.

After learning the [[Bros. Ball]], the protagonists next visit [[Gritzy Desert]], where they meet [[Kylie Koopa]], and find a secret entrance to the [[Koopaseum]], arriving in time to witness Princess Peach being swallowed whole by [[Petey Piranha]]. The brothers defeat the [[Shrooboid Brat]] in the arena, angering Princess Shroob who breaks the floor and sends them falling into [[Gritzy Caves]]. The brothers fight and defeat Petey Piranha, recovering a Cobalt Shard and saving Kylie Koopa (who had almost been fed to him too). They find Princess Peach, whose face is covered by a Shroob Mushroom, and take her back to the present day castle. Bowser attempts to kidnap her but falls through a time hole to [[Thwomp Volcano]].
[[File:Star Shrine.png|150px|thumb|left|The protagonists in the [[Star Shrine]].]]
After learning the [[Baby Spin]] and [[ Baby Cakes]], the brothers follow Bowser and travel to the top of the volcano. When they arrive, they find Peach's crown. After that, the volcano erupts and they flee down the right path. They meet Professor E. Gadd’s [[Elvin Gadd (past)|younger self]], who thinks up of an idea of making a machine that could douse the volcano's fire, which the older E. Gadd creates in the present time. He then uses his quickly built invention to spray water into the time hole and stop the volcano. After a skirmish with the angry resident, [[Mrs. Thwomp]], the Mario Bros. are carried into the volcano by her husband, [[Mr. Thwomp]], where they solve various puzzles and fight and defeat Bowser and Baby Bowser (who had been shot into the volcano after being blown away from Yoshi's Island). Bowser is sent careening back to the present while Baby Bowser flies off on his own, but before the protagonists can collect the princess, she is sucked up by the [[Shroob Mother Ship]]. The brothers board the ship and team up with Kylie to try and save Peach, but they all simply end up being ejected from the vessel, and also realize that Princess Shroob was disguised as Peach the whole time. The four Mario Bros. land in [[Toad Town]] and from there, travel to [[Star Hill]]. 

There they find the [[Commander Shroob]], his team of [[Support Shroob|Support Shroobs]], and a [[Shroob-omb]] who engage them in battle. Once Commander Shroob and his team are defeated, the four heroes head to the top of Star Hill where the protagonists talk to the [[Elder Princess Shroob|Cobalt Star's Spirit]] which tells them that when the find five out of the six parts of the Cobalt Star, they can enter [[Shroob Castle]].

The heroes head to the [[Star Shrine]], where another Cobalt Shard is located. The brothers then meet up with Toadbert and Kylie Koopa, who now knows how to clean Toadbert's picture, revealing the depiction of a second Shroob princess. Their group is attacked by the [[Elder Shrooboid]], which turns Toadbert and Kylie into Shroob Mushrooms before it could be stopped by the Mario Bros. After collecting another Shard from the vanquished Shroob, the Mario Bros. travel to the Shroob Castle in the past by way of the future castle and its many time holes. Mario and the gang take down the Shroob Mother Ship and finally find Princess Peach being held captive by Princess Shroob, who they battle and defeat. Peach shows them the final piece of the Cobalt Star but won't let them merge it with the other pieces, however before she can explain why, Baby Bowser swoops in and completes the Cobalt Star himself, releasing the [[Elder Princess Shroob]], who had been trapped in the star by Princess Peach. Baby Bowser is turned into a Shroob Mushroom for his troubles and Elder Princess Shroob attacks the Mario Bros. next, but they defeat her and she transforms into a purple mushroom.

Baby Luigi cries on the Shroob Mushroom that used to be Baby Bowser after Baby Mario accidentally [[Ground Pound]]s him, restoring his former self. Professor E. Gadd then uses his [[Hydrogush 4000]] invention to sprays a liquid with the same chemical makeup as baby tears all across the Mushroom Kingdom of the past, restoring everyone else who had been affected by the Shroobs. The Mario Bros. discover Bowser unconscious in Peach's Castle in the present and Elder Princess Shroob's mushroom flies into his mouth, turning him into [[Shrowser]] for one last attack on the Mario Bros. After Shrowser is beaten and the Shroob threat is finally put to rest forever, Toadsworth the Younger, Baby Peach, Baby Mario, and Baby Luigi all use the repaired time machine and travel back to their own time, bidding farewell to their future selves.

==Battle system==
[[File:SPD-Up.png|thumb|A battle taking place.]]
To start a battle, Mario, Luigi, or their baby selves must touch an enemy or perform a [[First Strike]] by jumping on or hitting the enemy with a hammer in the overworld. A first strike damages the enemy (if jumped on) or possibly stun them (if hit with a hammer) as the battle starts. If an enemy with spikes or fire is jumped on, the brother who jumped on the enemy is damaged. Additionally, if the enemy starts the battle by hitting a Bro. in the back, that brother cannot move until his turn. Since the game is a turn-based [[RPG]], the player and enemies take turns attacking each other; the brothers use [[Command Block]]s as the interface to select actions. The player can use well [[Action Command|timed attacks]] to deal more damage. The player can also counterattack the enemy to damage them (see below). The enemies never counterattack but can harm the brother if they have spikes or are on fire and are jumped on, though these elements cannot KO a brother, even if he has one HP left.

When a brother's HP hits zero, he passes out and remains in this state until the end of the battle (where he has one HP in the overworld) or if he is revived with a 1-Up Mushroom. If the babies and adults are separated from each other, the surviving brother carries the passed out one, though it greatly hinders on the surviving brother's ability to avoid enemy attacks. If the brothers are in Piggyback Mode, the adults take all damage from enemy attacks until they pass out, where the baby takes the passed out brother off-screen and fights on his stead. If the baby also passes out, the surviving brother pair carries him, also hindering their ability to avoid enemy attacks. If all in-battle brothers' HP reach zero, regardless if there are non-fighting brothers in the overworld, the player gets a [[Game Over]] and either restarts from the last save point or returns to Princess Peach's Castle.

If all enemies' HP are reduced to zero, the battle is won and [[Experience Point|EXP points]] and [[coin]]s are gained. Depending on the enemy defeated and what badges are worn, regular items, [[Bros. Items]], [[List of clothing in Mario & Luigi: Partners in Time‎|Clothing]], and [[List of badges in Mario & Luigi: Partners in Time|Badge]]s may be won as well.

===Stats===
Each brother has his own [[Heart Point|HP]], POW, DEF, [[Speed|SPEED]], and [['Stache|STACHE]] points. With enough EXP Points, a brother can level-up and increase each respective statistic. [[Mario]], [[Luigi]], [[Baby Mario]] and [[Baby Luigi]] lean towards certain stats: Mario and Baby Mario have increase in stats that favor of power and speed while Luigi and Baby Luigi's stats generally favor HP, defense, and stache. The babies have generally weaker stats than their adult counterparts barring their speed, where they outperform their adult counterparts at. Clothing and some badges can also alter a brother's stats.

|-
!Stat
!Description
|-
| align="center"|[[File:Stat HP MLPiT.png|link=HP]]
|HP (abbreviation of Heart Points) is the amount of life a brother has. When an enemy hits one of the brothers, he loses HP. When his HP reaches zero, he passes out, but can be revived with a [[1-Up Mushroom]] or [[1-Up Mushroom#Mario & Luigi series|1-Up Super]].
|-
| align="center"|[[File:Stat POW MLPiT.png|link=Power]]
|POW (abbreviation of Power) is how strong a brother is. The higher his POW stats are, the more damage he gives.
|-
| align="center"|[[File:Stat DEF MLPiT.png|link=Defense]]
|DEF (abbreviation of Defense) is how much damage a brother can lessen from an enemy hit. The higher his DEF stats are, the less damage he receives.
|-
| align="center"|[[File:Stat SPEED MLPiT.png|link=Speed]]
|SPEED is how fast a brother is. The more SPEED he has, the sooner he can attack an enemy in a given turn.
|-
| align="center"|[[File:StachePit.png|link='Stache]]
|The higher a brother's STACHE stats are, the greater there is a chance of a Lucky Hit, which doubles POW. Plus, it gives the brother discounts when buying and selling at shops. The babies also have this stat despite not having mustaches.
|}

===Moves===
During a battle, the four brothers have five choices when attacking, unless Mario and Luigi are not paired with the babies; instead, they would have four choices. They can use a jump move, a [[Hammer]] move, a [[Bros. Item]], use an item, or run from battle.

====Jump move====
[[File:Jump Battle Icon - MaLPiT.png|frame|left]]
During a jump move, a brother jumps on an enemy. When Mario jumps on an enemy, he uses {{button|ds|A}}, {{button|ds|B}} for Luigi, {{button|ds|X}} on Baby Mario, and {{button|ds|Y}} for Baby Luigi's jump. Hitting their button when they are about to land on the enemy does extra damage. The babies can participate in battle, assisting their older counterparts. If so, when the two older bros. attack and land on an enemy, the player should press the babies button, and then the adult brother's button. This deals more damage to the enemy.
{{br|left}}
====Hammer move====
[[File:Hammer Battle Icon - MaLPiT.png|frame|left]]
After Baby Mario and Baby Luigi enter the [[Vim Factory]], they get [[Hammer|hammers]] to use in battle. However, the adult Mario and Luigi cannot use this move without the babies with them, as they do not have hammers. When one of the babies attack with a hammer, the player must hit their button (either {{button|ds|X}} or {{button|ds|Y}}) when the tool shakes to deal more damage. If the player waits too long or hits the button too early, the hammer head falls off the hammer and the baby brother does much less damage. When the corresponding button is hit before they directly face the enemy, they trip and fall flat on the enemy, also yielding less damage. When the adult bros. are with the babies, they can perform a stronger attack with them. When doing this, the player must hit the adult button ({{button|ds|A}} or {{button|ds|B}}) to have Mario or Luigi lift up the baby. Then, they must hit the baby button ({{button|ds|X}} or {{button|ds|Y}}) when their hammer shakes. This deals more damage than a normal hammer attack. The hammer move does less damage than a jump move, and it is best used when fighting a spiked enemy. Flying enemies avoid the hammer altogether.
{{br|left}}
====Bros. Items====
[[File:Bros. Item Battle Icon - MaLPiT.png|frame|left]]
[[File:Normal shellkick.png|250px|thumb|The bros. using a Bros. Item.]]
[[Bros. Item|Bros. Items]] are special attacks that the brothers can use to deal more damage. Some Bros. Items require at least two brothers standing while some require all bros. Some items that require two bros. have special commands that can be used to deal more damage than normal with all four bros. Note that some items are unlocked later in the game than others.

{|class=wikitable width=100% cellspacing=0 border=2 cellpadding=3 style="border-collapse:collapse;"
|-
!Bros. Item
!Description
!Bros. Needed
|-
| align="center"|[[File:Green Shell Pit.png]]<br>[[Green Shell#Mario & Luigi:Partners in Time|Green Shell]] 
|One of the brothers kicks this item towards an enemy. It rebounds off the enemy, while the enemy takes damage, and back towards the other brother. The other brother must kick the shell back to the enemy to repeat the process, while the Green Shell increases its speed more times it is kicked. The Green Shell disappears when the enemy is defeated, sixteen successful hits are dealt, or if a brother misses it. If the brother using the item has his baby self piggyback, his baby self rides on the shell: if players press the baby brother's corresponding button, the baby brother spins the shell, dealing more damage to the enemy. However, if the player presses the spin button when the shell is going back to Mario or Luigi, the player will be not able to kick the shell again and will miss. This also happens with Red Shells.
|2
|-
| align="center"|[[File:Bro flower.png]]<br>[[Bros. Flower]]
|Both brothers toss fireballs at multiple enemies. The player should press the button of the brother when the big fireball is on the brother's hand. If a small fireball is thrown, it will decrease the length of the attack. If the brother's baby self is piggyback, pressing the corresponding baby button enables the brother to lob their fire balls, hitting aerial foes. This item can cause a [[burn]] status to enemies.
|2
|-
| align="center"|[[File:Canonball.PNG]]<br>[[Cannonballer]]
|All four brothers jump inside a cannon, which launches them into the top screen. A random order of the four brothers can be seen as they land, and players should press the corresponding button in order to deal more damage to an enemy.
|4
|-
| align="center"|[[File:IceFlower.PNG]]<br>[[Ice Flower#Mario & Luigi:Partners in Time|Ice Flower]]
|Identical to the Bros. Flower, except the brothers toss iceballs instead of fireballs. The only difference is that this item can randomly lower the enemies' Attack, Defense, and/or Speed.
|2
|-
| align="center"|[[File:Smash Egg.png]]<br>[[Smash Egg]]
|A brother kicks the egg to an enemy. As it flies in the air, the player must hold the corresponding button to let a brother build up energy to kick the egg at the enemy. When released with correct timing, the brother kicks the egg at the enemy. The process repeats back and forth until either the egg cracks or when the enemy is defeated. When the egg cracks, a possible free item can result out of it. When a baby brother is piggyback, he can jump and hit the egg to make it fall faster to deal more damage to the enemy. 
|2
|-
| align="center"|[[File:Pocket Chomp.png]]<br>[[Pocket Chomp]]
|A [[Chain Chomp]] is released, which chases a brother and goes offscreen. Then, as the brother approaches the enemy, the player should press the corresponding button when the brother lands on the enemy to deal more damage and run away from the Chain Chomp. The attack ends when the enemy is defeated or when the Chain Chomp catches the running brother. If three or more brothers are present during the battle, a baby brother occasionally rides on the chariot. Pressing the corresponding baby button causes the baby brother to spin his Hammer, causing more damage to the enemy if timed correctly.
|2
|-
| align="center"|[[File:PiT Trampoline sprite.PNG]]<br>[[Trampoline]]
|All four brothers jump on the trampoline, which launches them off screen. One brother comes down in a random order, and the player should press the corresponding to deal damage to enemies and keep the attack going. Another brother eventually comes down to a random enemy, and the process repeats, with each jump exponentially speeding up the process. The attack ends when the player fails to press the button at the right time or when all enemies are defeated.
|4
|-
| align="center"|[[File:CopyFlower.png]]<br>[[Copy Flower]]
|Many copies of the brothers are spawned, and they walk offscreen. In a completely random order, the brothers walk up to the enemy and jump on them. Players must execute a well-timed jump with the corresponding button to continue the attack and deal more damage to the enemy, with each jump exponentially speeding up the process. Once the enemy is defeated, the bros will begin jumping on the next foe. The process ends when a jump is failed or when all enemies are defeated.
|4
|-
| align="center"|[[File:Red shell pit.png]]<br>[[Red Shell#Mario & Luigi: Partners in Time|Red Shell]]
|Identical to the Green Shell, except once the enemy is defeated it will continue until a brother misses the shell or if all enemies are defeated.
|2
|-
| align="center"|[[File:MixFlower.png]]<br>[[Mix Flower]]
|Similar to the Bros. Flower, the player should press the button of the corresponding brother to build a giant fireball and keep it up in order to deal more damage. The bigger the fireball, the more damage it causes. After some period of time, when the player cannot keep up with the speeding up process, the fireball falls and deals damage to all opponents.
|4
|}

====Items====
[[File:Item Battle Icon - MaLPiT.png|frame|left]]
When choosing the item icon, the four heroes can use an item to recover [[Heart Point|HP]]. Other items, such as [[Refreshing Herb|Refreshing Herbs]], can heal status effects. When one of the bros. passes out, the other bros. can use a [[1-Up Mushroom]] or [[1-Up Mushroom#Mario & Luigi series|1-Up Super]] to revive him. However, once an item is used, the bro.'s turn is over. [[Pepper|Peppers]] are another type of item that can be used with this icon and can temporarily increase the bros. stats.

|}

====Flee====
[[File:Flee Battle Icon - MaLPiT.png|frame|left]]
Mario, Luigi, and the babies can both flee from battle when they choose the flee icon. When getting away, the player must hit either the {{button|ds|A}} or {{button|ds|B}} button to make Mario or Luigi flee. If the babies are in battle, the player must hit the {{button|ds|X}} or {{button|ds|Y}} button. However, if they do not do this quickly, one of the bros. falls and drop a large amount of coins unless a wallet badge is equipped. When both bros. have left the screen, they end up back in the overworld and continue their adventure. The player can cancel this attempt by pressing the {{button|ds|L}} button, though it uses up a turn. This cannot be used in Boss Battles.
{{br|left}}
===Avoiding attacks===
Mario, Luigi, or Baby Mario and Baby Luigi can either use their [[Hammer]] or [[Jump]] moves to avoid attacks. With their Jump move, the brothers can jump over the attacking enemy. When using the Hammer to avoid attacks, the player must hold Baby Mario or Baby Luigi's respective button (Baby Mario is {{button|ds|X}}, Baby Luigi is {{button|ds|Y}}) and release just as the enemy or its weapon hits.

The four bros. can also use these moves to counterattack. When they jump over an enemy, they may land on them, causing damage. Baby Mario or Baby Luigi can also hit enemies with their hammer during an enemy's turn. Either way, the enemy takes damage on its turn.

===Altered states===
[[:Category:Status effects|Altered states]] return from ''[[Mario & Luigi: Superstar Saga]]'', with the same conditions that can cause it. Certain enemies have attacks that can cause altered states, which hinder a brother in a way. The brothers can also inflict altered states on enemies as well with the [[Bros. Flower]], [[Ice Flower]], and [[Mix Flower]], as well as enhancing their stats with peppers. Over a period of time, altered states wear off, though the brothers can recover quicker from negative altered states if they use a [[Refreshing Herb]].

==Field features==
On the overworld, the brothers can navigate their environment. They can interact with a variety of objects such as blocks and switches and use various techniques to help with their progress of the game. During normal overworld progression, the DS bottom screen displays character control and progress while the top screen displays the map, character HP, coins, and where the brothers are currently located, alongside miscellaneous map features. When the babies are sent to locations only they can access, such as going down a hole or using a Trampoline, the top screen changes from the map to display the babies' control and progress.

===Techniques===
[[File:MLPIT Separated Groups.png|thumb|Baby Mario and Baby Luigi separate from their older counterparts]]
The brothers can use some techniques out of battle. All of the following techniques must be learned by progressing in the game, except for jumping. Each button is assigned to each brother, with {{button|ds|A}} being Mario's button, {{button|ds|B}} being Luigi's, {{button|ds|X}} being Baby Mario's, and {{button|ds|Y}} being Baby Luigi's. Players can switch action commands with {{button|ds|L}} and {{button|ds|R}}, demonstrated by the changing of the action icons, as soon as they learn different techniques. Unlike in ''Mario & Luigi: Superstar Saga'', players cannot switch the order of the brothers; Mario or Baby Mario is always the leader.

In the middle of action commands, players can cancel them by pressing the corresponding button that has "BACK" displayed on it.

==Minigames==
Along the quest, the brothers can play various minigames. These minigames are required to complete for the brothers to progress in the game. The Thwomp Caverns minigame can be replayed; the second spaceship minigame of the Shroob Castle can also be replayed, as it is part of the final levels of the game, where Stuffwell can use his Special Service Warpulator to warp back before that point.

*At [[Thwomp Caverns]], located in the [[Thwomp Volcano]], the [[Thwomp Bros.]] host two minigames. The older Thwomp Bros. operates a slot machine. In order to use it where Mario and Luigi need to roll into [[Bros. Ball]] and collect as much jewels as possible. If enough jewels are collected, Baby Mario can stop the slots with his hammer. Depending on the difficulty setting and the slots aligned, the brothers can receive various items as rewards, including coins or beans.
*The other minigame is hosted by the younger of the Thwomp Bros. In this minigame, Mario and Luigi must use the [[Baby Spin]] on Baby Mario and Baby Luigi for them to use a [[Whirlwind]]. On their descent, they need to collect as many jewels as possible, with the prizes dependent on the number of jewels collected.
*In the [[Shroob Castle]], two minigames involving a spaceship is played. The first minigame involves piloting the [[Shroob Mother Ship]] in order to take down smaller Shroob UFOs; the other, later minigame involves using the head of the Princess Shroob statue of the spaceship to shoot Shroob UFOs into the Shroob Mother Ship to destroy it. In this minigame, the height of the spaceship is controlled by Luigi, Baby Mario, and Baby Luigi hitting blocks, where the spaceship rises to the height in tandem with the rising and falling bar. Hitting the block stops the bar, which indicates the height the ship will rise to. Mario's block fires a laser beam, used to attack Shroob UFOs. Once Mario fires his laser, the height of the ship resets to the bottom. All characters are not required to hit the block for Mario to use the laser. In the second spaceship minigame, the ship the brothers are piloting have a set number of hit points, which get decreased when a Shroob UFO runs into it. When all hit points for the player are depleted, the ship crashes and the player gets a Game Over.

==Shops==
[[File:ShroomShop.png|thumb|The [[Shroom Shop]]]]
{{Main|List of shops in Mario & Luigi: Partners in Time}}
Four shops are found in ''Mario & Luigi: Partners in Time''. One, the [[Shroom Shop]], is found in the main hub in [[Princess Peach's Castle]]. The rest are found in levels throughout the game. [[Fawful's Bean 'n' Badge]] sells Badges exclusively at a price of [[Bean|beans]] rather than coins.

*[[Shroom Shop]], located in [[Princess Peach's Castle]]
*[[Monty Mart]], located in [[Gritzy Caves]]
*[[Gramma's Place]], located in [[Toad Town]]
*[[Fawful's Bean 'n' Badge]], located in [[Peach's Castle Dungeon]]

==Clothing==
{{main|List of clothing in Mario & Luigi: Partners in Time‎}}
[[File:Clothing - MaLPiT.png|frame|left]]
Clothing boosts the brothers' stats. There are two categories of clothing: one made specifically for the adult brothers and one made specifically for the baby brothers. Unlike ''Mario & Luigi: Superstar Saga'', clothing is not restricted to a specific brother. Clothing is either dropped by enemies, found in blocks, or purchased in shops.
{{br|left}}
==Badges==
{{main|List of badges in Mario & Luigi: Partners in Time}}
[[File:Badge - MaLPiT.png|frame|left]]
Badges cause miscellaneous effects when worn and can be universally worn by all brothers. Such effects include unlimited use of Bros. Items or restoring HP every turn. They do not increase a brothers' base stats. Badges can be purchased in shops, exclusively purchased in [[Fawful's Bean 'n' Badge]], dropped by enemies, or won by completing minigames.

==Notable mistakes and errors==
*In the North American instruction booklet, page 27 has a Japanese screenshot, where "Stache" is listed as "''Hige''".
*In the North American instruction booklet, page 32 has the following sentence: "Approach either side and speak to the sales-Toad to make the corresponding menu will appear," where the word ''will'' is an unnecessary addition to the sentence structure.

==Staff==
{{main|List of Mario & Luigi: Partners in Time staff}}
[[AlphaDream]] developed the game, as they did with other games in the ''Mario & Luigi'' series. [[Shigeru Miyamoto]] and Tetsuo Mizuno produced the game, with [[Satoru Iwata]] as the executive producer. [[Yoko Shimomura]], who composed music for the other ''Mario & Luigi'' games and ''[[Super Mario RPG: Legend of the Seven Stars]]'', also composed music for this game.

==Reception==
===Critical reception===

Retrieved October 28, 2015.</ref> Critics generally praise the humor, characters, and graphics of the game, as well as its use of the dual screen and its rumble feature. Several criticisms include the long, drawn out boss battles and the difficulty coordinating the game's four characters.

Craig Harris of IGN has lauded the game, giving it a nine out of ten.<ref>Harris, Craig. November 28, 2005.

Thomas Bowskill of Nintendo Life has also given the game a 9/10, also praising the gameplay, the comedy, and the sound, but added that the game is not replayable and how actions in the past do not influence the future.<ref>Bowskill, Thomas (February 6, 2006) [http://www.nintendolife.com/reviews/ds/mario_and_luigi_partners_in_time Review of Mario & Luigi: Partners in Time] ''Nintendo Life''.

|9/10
|align="left"|"''Partners in Time does a fantastic job following up the already fantastic Superstar Saga on the Game Boy Advance. Mario & Luigi: Partners in Time has an even crazier story, funnier dialogue, more elaborate puzzles, and more action-based fights than the original game. But even with all the clever additions the Nintendo DS version brings to the table, the original quest is never left in the dust and is still on the same playing field for those who haven't experienced that handheld adventure yet. And though it doesn't explore the Nintendo DS platform on a technical level, Partners in Time definitely approaches the handheld in extremely creative ways.''"

However, this is by far the best RPG currently available for the DS, and its use of the dual screens opens up gameplay possibilities that just aren't available on any other system. Taking twenty hours or so to complete, it's also going to last longer than most portable games. Fans of the other Mario RPGs should definitely check out Partners in Time for its terrific story and brain-twisting level design.''"

==''Super Mario-Kun'' adaptation==
[[File:SMKun Volume36.jpg|thumb|The cover of volume 36 of the ''Super Mario-Kun'', featuring characters from ''Mario & Luigi: Partners in Time''.]]
''Mario & Luigi: Partners in Time'' has been adapted into the ''[[Super Mario-Kun]]'' manga, written and illustrated by Yukio Sawada. The story arc related to ''Mario & Luigi: Partners in Time'' spans across three volumes: volumes 35, 36, and 37. Though it follows the source material, it introduces various key story element differences, as every ''Super Mario-Kun'' volume adaptation of their respective game.

===Differences in the ''Super Mario-Kun'' manga===
*Luigi is involved in the [[Junior Shrooboid]] boss fight, though against his will; Mario uses him as a weapon to defeat the Junior Shrooboid.
*All Shroobs are able to speak coherently from the beginning, including [[Princess Shroob]].
*Although Mario and Luigi do arrive at the [[Hollijolli Village]], they do not encounter the [[Hollijolli Mayor]]. Instead, the Shroobs engage them immediately and defeat them.
*[[Bowser's Castle#Mario & Luigi: Partners in Time|Bowser's Castle]] does not appear at all. After the Mario Bros. encounter the Baby Mario Bros., they travel to the [[Shroob Castle]].
*[[Snoozorb]]s, which are late-game enemies, appear relatively in the beginning of the ''Super Mario-Kun''; the brothers fight it when they arrive to the Shroob Castle.
*The Snoozorb fight teaches Mario and Luigi the technique of the [[Bros. Ball]], where they use it as an attack rather than a utility move for transportation. Later in the story arc, a four-brother version of the ball is used against the [[Elder Princess Shroob]].
*Though it is discovered that Toads are being used for fuel in the [[Toadwood Forest]] and [[Vim Factory]], [[Toadiko]] does not appear.
*Baby Mario and Baby Luigi receive their hammers from supplies that Toadsworth the Younger provides, while the [[Hammer Bro (Mario & Luigi: Partners in Time)|Hammer Bros.]] do not appear at all. As a result, Mario and Luigi do not get captured in the Vim Factory.
*Toads do not get their energy sapped from being strapped onto trees. Rather, [[Swiggler]] sucks their energy directly from them.
*Baby Luigi carelessly spinning around with his hammer gives Baby Mario the inspiration for the [[Baby Drill]] move, where it is used as an attack, similar to the Bros. Ball, rather than the Hammer Bros. teaching the move to them.
*The Yoob is a friendly giant, hungry Yoshi who gets taken over and manipulated by [[Sunnycide]]. Other Yoshis and [[Toadbert]] do not appear.
*Neither [[Kylie Koopa]] nor the [[Koopaseum]] appear in the manga. Rather, the four brothers travel to [[Gritzy Desert]] and eventually take a Warp Pipe down to [[Gritzy Caves]].
*Petey Piranha is portrayed as a female character, alongside Piranha Plants (called ''bero pakkun'', which roughly translates to "Tongue Piranhas") with a Cobalt Star Shard as part of her teeth.
*The characters do go to [[Thwomp Volcano]] and fight [[Mrs. Thwomp]], but do not enter [[Thwomp Caverns]], nor fight Baby Bowser and Bowser. In fact, Bowser does not appear at all in this story arc.
*The [[Star Hill]] is portrayed as a snowy location, where Baby Luigi rebuilds a destroyed Snowman. The Snowman later helps the brothers fight the [[Commander Shroob]], the [[Shroob-omb]], and the [[Support Shroob]]s, though the Commander Shroob destroys it. As a result, it gives Baby Luigi an [[Ice Flower]], which helps him defeat the Commander Shroob and his army.
*At the [[Star Shrine]], Luigi proves his worth by using a [[Copy Flower]] on the [[Piranha Planet]] and defeating it, while also obtaining the [[Aurora Block]].
*An entire chapter is devoted to the Marios and Luigis fighting each other, due to the deception of a [[Tanoomba]].
*The [[Shroob Mothership]] is taken down due to Baby Mario tricking [[Princess Shroob]] with a false mail delivery.
*The Princess Shroob is the character who fully assembles the Cobalt Star together, rather than [[Princess Peach]] holding on to the last Cobalt Star Shard and Baby Bowser intervening.
*The Princess Shroob and Elder Princess Shroob fight simultaneously, though the Princess Shroob mostly stays on the sidelines.
*A chapter is devoted to Toadsworth and Toadsworth the Younger taking care of Baby Peach, when a [[Shroobsworth]] and an [[Intern Shroob]] appears and attacks them. The two Toadsworths intervene to defend Baby Peach from their attacks, until E. Gadd gives Baby Peach [[Perry]], the parasol. The parasol causes Baby Peach to activate her anger vibe, thus defeating the two enemies. These actions reference ''[[Super Princess Peach]]''.
*Baby tears weaken the Elder Princess Shroob, though a rainbow shell is the item that ultimately defeats her.
*Mario and Luigi are the characters who leave with the time machine, rather than the past versions of the characters leaving.
*[[Shrowser]] is referenced in the epilogue to the story arc, where [[Baby Bowser]] eats the purple mushroom containing the essence of the Elder Princess Shroob. He battles the Baby Mario Bros., but before the Baby Mario Bros. retaliate, he poops the Elder Princess Shroob mushroom.

==References to other games==
[[File:PiT Toadsworth another castle.png|thumb|[[Toadsworth the Younger]]'s reference to ''[[Super Mario Bros]]'']]
*''[[Super Mario Bros.]]'' - When the wind blew away Baby Peach, [[Toadsworth the Younger]] asked the Baby Mario brothers to save her, saying: ''"You will save her, won't you? I assure you, she's NOT in another castle or anything."'' This is a reference to the repeated [[Toad (species)|Toads]]' line: ''"Thank you, Mario! But our princess is in another castle!"''
*''[[Super Mario All-Stars]]'' - One of Shrooboid Brat's attacks involves having the audience giving him either Fire Flowers, Mushrooms, or Poison Mushrooms. The Poison Mushrooms' appearance is exactly the same sprite of their appearance in the remake of ''[[Super Mario Bros.: The Lost Levels]]''.
*''[[Yoshi's Cookie]]'' - The cookies from this game reappear in [[Yoshi's Island (place)|Yoshi's Island]].
*''[[Super Mario World 2: Yoshi's Island]]'' - This game features the return of [[Baby Mario]], [[Baby Luigi]], [[Baby Bowser]], and the [[Chomp Rock]]. Also the player can travel to Yoshi's Island, whose first area has the same music as this game's alternate title music. In addition, [[Kamek]] makes a reference to his attempted kidnapping of Baby Mario and Baby Luigi in ''[[Super Mario World 2: Yoshi's Island]]''.
*''[[Super Mario RPG: Legend of the Seven Stars]]'' - In the beginning of the game, the Cobalt Star shard is in a block similar to the regular [[Treasure Chest]] blocks in this game.
*''[[Super Mario 64]]'' - The music that plays within [[Princess Peach's Castle]] is a cover of "Inside the Castle Walls".
*''[[Luigi's Mansion]]'' - Professor E. Gadd moves to the Boo Woods as a young man where he is later found by Luigi, foreshadowing the events of the game. Also, music from cutscenes involving E. Gadd are a cover of the ''Luigi's Mansion'' main theme.
*''[[Super Mario Sunshine]]'' - [[Shine Sprite]]s return as a source of light. Also, the Hydrogush 4000 resembles [[F.L.U.D.D.]]. [[Petey Piranha]] appears as a boss.
*''[[Mario Kart: Double Dash!!]]'' - Some of the voices are re-used from this game.
*''[[Mario & Luigi: Superstar Saga]]'' - [[Fawful]] runs [[Fawful's Bean 'n' Badge]]. Additionally, a picture of [[Prince Peasley]] appears in the [[Shroom Shop]] on a poster about [[bean]]s. The ending theme for ''Mario & Luigi: Partners in Time'' is a cover of the ending theme from ''Mario & Luigi: Superstar Saga''. Also, before the fight with [[Bowser]] and [[Baby Bowser|his younger self]], Bowser affectionately calls Baby Bowser a 'little [[Firebrand]]', Mario's skill from said game. When fighting the Hammer Bros in the Vim Factory, they use an attack that is identical to the Bros. move, "Knockback Bros", performed by Mario and Luigi in ''Mario & Luigi: Superstar Saga''. Also two enemies, [[Trunkle]] and [[Mecha-Chomp]] have similar battle style to [[Mrs. Thwomp]] and [[Shroid]] respectively. Also, during the battle with [[Elder Princess Shroob]], one of her attacks involves striking her own [[Shroob UFO|UFO's]] with fire and lightning to attack the Bros. UFO's on fire hit Mario, while those struck by lightning hit Luigi, referencing the Firebrand and [[Thunderhand]] skills from said game.
*''[[Paper Mario: The Thousand-Year Door]]'' - [[Dark Boos]] first appeared in this game. Toadsworth the Younger also references the [[Bristle]] enemy that has only appeared in this game while admonishing his present day counterpart.

==References in later games==
*''[[Super Smash Bros. Brawl]]'' - A [[Shroob]], Stuffwell, and Luigi carrying Baby Luigi appear as stickers. Also, a cover version of the [[Gritzy Desert]] theme returns for the [[Mushroomy Kingdom]] stage. The boss theme was [[List of Super Smash Bros. Brawl pre-release and unused content|originally]] going to be in ''Super Smash Bros Brawl'', but was removed in the final version. One of Luigi's poses in this game resembles his artwork for ''Mario & Luigi: Partners in Time''.
*''[[Mario & Luigi: Bowser's Inside Story]]'' - Three Shroobs appear as optional bosses. [[Junior Shrooboid]]s, [[Commander Shroob]]s, and [[Elder Princess Shroob]] cameos in the background of that stage. Also in the audience from Fawful Theater there's a Shroob in the audience. There are some gear that has "Shroob" in the name.
*''[[Mario & Luigi: Dream Team]]'' - Kylie Koopa appears in this game, along with a picture of a Shroob hanging on a wall in the house where she is found.
*''[[Super Smash Bros. for Nintendo 3DS / Wii U]]'' - One of Luigi's poses in this game resembles that of his solo artwork from ''Mario & Luigi: Partners in Time''.
*''[[Mario & Luigi: Paper Jam]]'' - [[Petey Piranha]] returns as a boss in this game. Also, a cover version of Peach's Castle can be heard. Finally, the tutorial theme in ''Mario & Luigi: Paper Jam'' is a cover version of ''Mario & Luigi: Partners in Time''{{'}}s tutorial theme.
*''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]'' - The redesigned [[Yoshi Theater (Mario & Luigi: Superstar Saga)|Yoshi Theater]] has a poster advertising a movie about a Shroob invasion. Additionally, when encountered in the new ''Minion Quest'' mode, E. Gadd mentions he is beginning to build a time machine, thus setting up for the events of ''Partners in Time''.

==Pre-release and unused content==
{{Main|List of Mario & Luigi: Partners in Time pre-release and unused content}}
[[File:MLPIT Beta-Scoot Bloop.PNG|thumb|The unused Scoot Bloops]]
A pre-release screenshot depicts Mario, Luigi, and their baby selves fighting two red shoe-clad Blooper foes (called Scoot Bloops) in the Vim Factory. Unfinished code for the Scoot Bloops remain the final build of the game. There are also screenshots of the four brothers using what appears to be a purple Spiny Shell as a Bros. Item. This item would act like a Koopa Shell, but would be hammered instead of kicked.

==Glitches==
{{Main|List of Mario & Luigi: Partners in Time glitches}}
===? Block Teleport===
In Thwomp Caverns, players should use the Baby Spin in the cyclone. If [[Baby Mario]] lands on the ? Block on the left platform, [[Baby Luigi]] stays there, and [[Baby Mario]] warps to the platform above. Players cannot enter piggyback mode or change to the adults while this glitch is occuring. This glitch can be fixed by moving [[Baby Mario]] into the spikes, which takes both babies to the platform above.

==Quotes==
{{Main|List of Mario & Luigi: Partners in Time quotes}}
*''"I'm afraid our dear Toadsworth has worried himself into a state of shroomshock."'' -[[Dr. Toad]]
*''"BACK TO ADVENTURE!"'' -[[Stuffwell]]
*''"I say to you WELCOME! Welcome to [[Fawful's Bean 'n' Badge]]!"'' -[[Fawful]]
*''"You are true and courageous. Your heart is filled with virtue and concern for your brother. I do recommend you watch your diet, however it is also filled with much Alfredo sauce. You should especially cut down on carbora, though it will be hard, for that is very tasty. If you curb your appetite, do some light cardio work and continue to ward your brother, you will no doubt grow to be a figure of immense popularity, yet not grow an immense belly. You may pass and I do recommend puttanesca; that stuff is great."'' -[[Star Gate]]

==Trivia==
*The solo artwork for Baby Mario incorrectly depicts him with red shoes, instead of light-blue. [[:File:Hammerbabymario.png|Other]] [[:File:Normal shellkick.png|artwork]] [[:File:Copy.png|depicts]] [[:File:Normal chompattack.png|him]] with the correct light-blue shoes.
*This is the only ''Mario & Luigi'' game to lack a BP stat (or its variations).
*When booting up the game, only Mario and Luigi's voices are heard saying, "Nintendo!". Once the game gets to a point when Mario and Luigi meet their infant counterparts, all four will say "Nintendo!". However, if the game reaches a point where Mario and Luigi are seemingly killed by the Shroobs near the Koopa Cruiser, if the player saves and resets, only Baby Mario and Baby Luigi's voices are heard and they are the only ones present on the title screen. This does not occur at any other point in the game where the babies are separated from the adults.
*This is the only ''Mario & Luigi'' game not to be created from the ground up (either as a new title or remake) for the Nintendo 3DS.
