'''''Mario & Luigi: Bowser's Inside Story''''' is a [[Nintendo DS]] game developed by [[AlphaDream]] and published by [[Nintendo]]. It was released worldwide in 2009 and in South Korea in 2011. It is the third title in the [[Mario & Luigi (series)|''Mario & Luigi'' series]], preceded by ''[[Mario & Luigi: Partners in Time]]'' for the Nintendo DS in 2005 and succeeded by ''[[Mario & Luigi: Dream Team]]'' for the [[Nintendo 3DS]] in 2013. The last part of the game's title is a pun on "inside story," a term that refers to the "true" tale of an event from the perspective of an insider who participated in the action, as opposed to an outsider who only hears about the event later on. In this case, the game is a literal inside story, as [[Mario]] and [[Luigi]] have to adventure through [[Bowser]]'s insides. The game's European Spanish, European French, and Italian name is a pun on the title of the famous novel ''{{wp|Journey to the Center of the Earth}}''. The original French name is ''Voyage au centre de la Terre'', the Spanish name is ''Viaje al centro de la Tierra'', and the Italian name is ''Viaggio al centro della Terra''.

This is the only non-3DS installment in the ''Mario & Luigi'' series not to be released on the [[Virtual Console#Wii U|Virtual Console]] for the [[Wii U]].

A Nintendo 3DS [[Reissue#Remakes|remake]] of the game, titled ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]'', was released in Japan on December 27, 2018, and elsewhere in January 2019. Outside Japan, the release year marks the 10th anniversary of this game. This is the second game in the ''Mario & Luigi'' series after ''[[Mario & Luigi: Superstar Saga]]'' to have a remake. This game also marks the debut of [[Starlow]], who would become a recurring character in the series.

==Story==
[[File:Bowser's Inside Story ToadBlorbs.png|thumb|The blorbs being discussed.]]
After the [[Mushroom Kingdom]]'s citizens start contracting the [[blorbs]], a disease that swells [[Toad (species)|Toads]], [[Princess Peach]] holds an emergency conference meeting at [[Peach's Castle|her castle]], which includes [[Mario]], [[Luigi]], [[Toadbert]], [[Toadsworth]], and a Star Sprite named [[Starlow]]. [[Bowser]] crashes in and is sent flying out of Peach's Castle after easily being defeated by Mario, eventually landing in [[Dimble Wood]], and after regaining consciousness, he comes across a cloaked merchant (who is [[Fawful]] in disguise). The merchant gives him a "[[Vacuum Shroom|Lucky Mushroom]]" that causes Bowser to inhale his surroundings. He returns to Peach's Castle and uses this ability to suck in everyone who attended the conference.

Mario, Luigi, and Starlow reawaken inside the [[Trash Pit]] area of [[Bowser's body]], where they acquire hammers and use them to hit an [[Funny Bone|exposed nerve]] and rouse Bowser, who had been dumped in [[Cavi Cape Cave]]. Starlow, who talks to Bowser throughout the game, withholds information surrounding the Mario Bros.' whereabouts and assists him in remembering the past events. Bowser then encounters Fawful, who explains that the blorbs and the Vacuum Shroom he gave him were all part of a plan to conquer both the Mushroom Kingdom and [[Bowser's Castle]]. He sends out his minion, [[Midbus]], whose speech irritates the Koopa King so much that he decides to pick a fight with him. Bowser loses to Midbus, and he and Fawful abandon him.

Bowser helps a stranded [[Broque Monsieur]] get back on [[Plack Beach]], where the sentient block rewards him a [[Vacuum Block]], allowing him to control his sucking abilities. After defeating the [[Sea Pipe Statue]], Bowser drinks water which allows Mario and Luigi to enter the [[Pump Works]] and defeat the [[Scutlet (boss)|Scutlet]] bug that was blocking his fire breath at the [[Flame Pipe]]. Starlow starts using the alias "Chippy" to Bowser. After subduing Broque's pet dog [[Broggy]], Bowser enters Dimble Wood, where he eventually comes across three of his minions: [[Sergeant Guy]], [[Corporal Paraplonk]], and [[Private Goomp]]. They plan to retake Bowser's castle with a [[Bomber Bill|Banzai Bill]] launcher, where Bowser is required to find ammunition. Bowser procures a giant carrot as a makeshift missile, but the owner, a Wiggler, makes him eat it and then attacks him. After he obtains the Banzai Bill from the Wiggler, Bowser is then overcome with stomach pain caused by consuming a parasitic [[Durmite]] along with the carrot; Mario and Luigi defeat it in battle.

After his stomach issue is resolved, Bowser proceeds to launch the Banzai Bill towards Bowser Castle. However, Midbus dodges his Banzai Bill by launching the castle and landing it on him. The Mario Bros. revive Bowser from the [[Rump Command]], which unintentionally turns him as giant as the castle. After Bowser defeats the castle, it flies away with him in pursuit, traveling through [[Bumpsy Plains]] and [[Bowser Path]] to reach the destination. Bowser deflects Midbus's iron ball, which knocks the castle down. Entering his castle, Bowser discovers that Fawful has turned it into a theater and brainwashed most of [[Bowser's Minions]] into a pack of his own adoring fans. Fawful himself arrives and tricks Bowser, forcing him to perform a cage match with Midbus on stage. When Bowser wins, his prize is being forcibly fed fattening foods cooked by Fawful, gaining so much weight that he breaks through the floor and becomes trapped.

[[File:PeachDarkStar.png|left|thumb|Peach tells the story about the Dark Star.]]
Exploring the newly opened [[Flab Zone]] and defeating some [[Kretin]] enemies, Mario and Luigi are reunited with Princess Peach, who explains that Fawful is actually after the [[Dark Star]], an evil entity locked away under Toad Town that can only be revived using Peach herself. Fawful then uses a laser to extract Peach from Bowser and he and Midbus leave with her, while Bowser falls the rest of the way through the floor onto a treadmill they placed beneath him in the basement. He literally burns off all the excess fat, igniting a crate of Bob-ombs in the process which sends him blasting off back to Cavi Cape, falling into the [[Tunnel]]. He meets up with some [[Monty Bros.|Monty Mole minions]] and helps them drill all the way to Toad Town, but when Bowser wanders into the corridor leading to the Dark Star, the security system activates and electrocutes him, rendering him unconscious.

Mario and Luigi gain access to the [[Pipe Yard]] in Bowser's body, which allows them to use warp pipes to return to the outside world. They emerge in the [[Toad Town Caves]] themselves and try to head off and stop [[Fawful]], but arrive too late. Fawful takes the Dark Star to Peach's Castle and uses its power to create a barrier preventing the Mario Bros. from following him. With no other option, they head to [[Dr. Toadley]] to try and do something about the blorbs problem instead, but Bowser arrives at the clinic as well and the three battle, with Bowser losing. Dr. Toadley then tells Mario and Luigi that they need to collect three [[Star Cure]]s to cure the blorbs and possibly find a way into the castle. Bowser awakens, hears this, and rushes off, determined to find the cures before the Bros. Dr. Toadley then reveals to Mario and Luigi that the first cure is held by Durmite inside Bowser's body, and they head back in to get it. They locate Durmite immediately, but it flees through an impassable, [[Boo]]-like barrier, stopping the Mario Bros. in their tracks.

[[File:M&LBIS Boo-Ray Machine screenshot.png|thumb|Yikk presents the Boo-Ray Machine.]] 
Meanwhile, Bowser heads to the shores of [[Blubble Lake]], where his sneezes raise the propeller-topped [[Tower of Yikk]] out of the water and straight onto him. The Mario Bros. supersize Bowser again and he defeats the moving tower, venturing inside once he shrinks back to his regular size and meeting the ghost of [[Yikk]], who shines his invention, the [[Boo-ray Machine]], on Bowser's gut. The light from the machine causes the Boo-like barrier to disappear and help Mario and Luigi navigate [[Energy Hold|the maze beyond them]], allowing them to track down Durmite, who reveals herself to be a sage named [[Wisdurm]]. She battles them, turning to a butterfly after her defeat, dropping the Star Cure, and flying off.

Bowser leaves the tower and meets up with Private Goomp, who tells him that he already had one of the Star Cures locked away in his treasure chamber, having recently stolen it from an old Koopa named [[Kuzzle]]. Bowser returns to his castle, regaining access to his treasure vault by pushing a statue of Fawful through the barricades in the floor, only to find that the Monty Bros. are now under Fawful's control and have built a railway straight through the vault. They use the [[Fawful Express]] to ram him out of the castle and into a boulder, resulting in another emergency revival and a giant battle between Bowser and the train. Returning to his vault after destroying the train, Bowser realizes that he has forgotten the combination to the safe that the Star Cure is stored in and asks "Chippy" to retrieve it for him. In the [[Memory Banks]], Mario and Luigi have to defeat [[Bowser Memory M and Bowser Memory L|blocky doppelgangers]] of themselves, crafted from Bowser's own memories of them. After that, they reassemble a puzzle representing the memory and Bowser opens his safe, only to be pushed in by Private Goomp, Sergeant Guy, and Corporal Paraplonk, who had turned to Fawful's side. With nothing else to do in the cramped safe, Bowser eats the Star Cure, and it is retrieved from his [[Gut Check (location)|gut]] by the Mario Bros.

Mario and Luigi return to Toad Town and are sent after the final Star Cure by Dr. Toadley. Guided by the doctor's messenger bird, [[Birdley]], they meet the sage known as [[Chakron]] at the top of a cliff over Plack Beach, but he will only give them the Star Cure if they can knock him out of the pose he has held for a thousand years. After a cryptic hint from Chakron, the Bros. head for Dimble Wood to collect Attack Pieces for the ground-shaking [[Snack Basket]] move, but Mario is kidnapped by a [[Sockop]] and has to be rescued by Luigi, who wears a [[giant Sockop|knocked-out Sockop]] like a [[Goomba's Shoe]] to sneak into the enemies' territory. Reunited and having gathered all the pieces, the brothers return to Chakron and knock him over, so true to his word, he gives them the final Star Cure.

[[File:M&LBIS Miracle Cure screenshot.png|thumb|left|The Miracle Cure curing the blorb-infected Toads.]]
Back at the clinic, Dr. Toadley creates the [[Miracle Cure]] from the three Star Cures, which flies around ridding all the Toads of the blorbs and then allows Mario and Luigi to blast their way through the barriers to get to Peach's Castle. They search the gardens for a way in and are attacked by Midbus, who uses the remote-control [[Junker]] robot to fight them. The Mario Bros. win the battle, and the robot goes haywire, throwing the safe containing Bowser into a pile of garbage, breaking it open. Bowser's back seized up from being in the cramped safe for so long, so Mario and Luigi go back inside him to fix it, allowing him to break into Peach's Castle for them.

Bowser fights his way to Fawful and Midbus as they are slowly awakening the Dark Star. Fawful supercharges his minion into [[Blizzard Midbus]], but Bowser wins the ensuing fight and Midbus's new ice powers end up freezing him solid. Bowser punches out Fawful as he tries to absorb the Dark Star's powers and he only gets a portion of it, with the rest of the revived evil entity forcing its way inside Bowser. Mario and Luigi chase the Dark Star [[Airway (Mario & Luigi: Bowser's Inside Story)|around]] as it absorbs Bowser's DNA and takes on his characteristics, eventually emerging as an incomplete copy of Bowser, which sucks up Peach and floats off in search of the rest of its power. Bowser goes after it but is sidetracked by a final giant battle against Peach's Castle, which had been transformed into [[Super Peach's Castle of Fury|a giant robot]] by Fawful. He then battles Fawful himself, now souped-up by the Dark Star's powers into [[Dark Fawful]]. Bowser wins the fight and Fawful turns into a small ball of dark energy and tries to flee, but he gets absorbed by the Dark Star, allowing it to fully transform into [[Dark Bowser]].

The real Bowser goes after his copy, chasing it to the tallest tower where it deposits the unconscious Peach before being confronted by Bowser, who aims to capture Peach, both castles and the Dark Star's powers. The final battle is waged on two fronts, starting off with Bowser fighting his clone, before punching it in the gut and forcing it to spit up Fawful. Bowser sucks up the little ball of energy and Mario and Luigi take over the fight, defeating both Fawful and the Dark Star Core inside Bowser. This leaves Dark Bowser unstable, and the real Bowser punches it until it explodes, freeing the Mushroom Kingdom from the Dark Star’s influence for good.

Inside Bowser, a battered and unstable Fawful appears in front of the Mario Bros., seemingly accepting defeat to them and saying that he will go away permanently, but he is actually faking it as he uses this opportunity to try and take the Mario Bros. with him in a final explosion of his own while sporting a large, dying grin on his face. All this accomplishes though is making Bowser eject everyone he had inhaled. The liberated Toads and the now-conscious Peach move to congratulate Mario and Luigi on a job well done, and Bowser, confused and angry, realizes that the brothers had been inside his body the whole time. Starlow dismissively tells Bowser to not worry about what's in the past but discovering that she was his supposedly loyal minion "Chippy" throws him into a complete rage. The Toads and the Princess flee from the scene, and the [[List of Mario & Luigi: Bowser's Inside Story staff|credits]] show a montage of still images showing that Bowser loses the ensuing fight.

[[File:EndCake MLRPG3.png|thumb|Bowser's cake.]]
Afterward, the heavily-injured Bowser is seen lying in bed at his castle while Private Goomp, Sergeant Guy, and Corporal Paraplonk beg him for forgiveness over their treason. Birdley arrives with a package from Peach, but when Starlow pops out of it to check in on him, Bowser angrily tells her to leave, as he is too busy fixing his castle to attack again anytime soon. He then lets the trio rejoin the rest of his army in helping with the repairs, and only once he is sure he is alone does Bowser open the package, revealing a thank-you cake with his face, Mario, Luigi, and Peach on it. 

As in the other ''Mario & Luigi'' games, there is no "Endless Play" feature. As such, if the player plays the game after it is beaten and the ending is done, the game just starts from the last save point, before the final battle.

==Battle system==
The battle system of ''Mario & Luigi: Bowser's Inside Story'' is similar to that of its predecessors. There are some new additions to the system. In this installment, all [[Action Command]]s are evaluated based on how well they are performed. There are five evaluation levels. Ranging from the worst to the best, these levels are: Nothing, OK, Good, Great, and Excellent. The better an Action Command is performed, the more damage an attack does. Receiving a Nothing is equivalent to not performing an Action Command at all. This is carried into all the later installments of the series. 
===Stats===
Each brother and Bowser have their own [[Heart Point|HP]], [[Special Point|SP]], POW, DEF, and [[Speed|SPEED]], as well as [[Stache|STACHE]] points for the brothers, and HORN points for Bowser. When they finish a battle, they each gain [[Experience Point|EXP Points]] and [[coin]]s. With enough Experience Points, they can level-up and increase each respective statistic. 
{|class=wikitable width=100% class=wikitable
|-
!Stat
!Description
|-
|align="center"|[[File:StatHPMLBIS.png|link=HP]]
|HP, or '''H'''eart '''P'''oints, indicate the amount of remaining health a character has. When an enemy hits a character, they lose HP. When their HP reaches zero, they pass out, but can be revived with a [[1-Up Mushroom]] or a [[1-Up Mushroom#Mario & Luigi series|1-Up Deluxe]]. HP can be replenished with a [[Mushroom]], a [[Nut]] or a [[Hot Drumstick|Drumstick]] (Bowser only).
|-
|align="center"|[[File:StatSPMLBIS.png|link=SP]]
|SP, or '''S'''pecial '''P'''oints, indicates how many times Mario, Luigi, or Bowser can use a Special Move. Each attack uses up a certain amount of SP, draining the total. SP can only be restored by ingesting [[Syrup Jar]]s.
|-
|align="center"|[[File:StatPOWMLBIS.png|link=Power]]
|POW, or '''Pow'''er, is how strong the fighter is. POW determines how much damage they can inflict.
|-
|align="center"|[[File:StatDEFMLBIS.png|link=Defense]]
|DEF, or '''Def'''ense, is how much damage the character can block from an enemy hit. A higher DEF stat means less damage is taken.
|-
|align="center"|[[File:StatSPEEDMLBIS.png|link=Speed]]
|SPEED is how fast the character is. In any given battle, the fighter with the most SPEED gets to attack first. The turn then continues, allowing fighters with subsequently lower SPEED to attack until the fighter with the lowest SPEED has attacked. The fighter with the most SPEED then gets to attack again, and the cycle continues until a fight is over.
|-
|align="center"|[[File:StatSTACHEMLBIS.png|link=Stache]]
|STACHE, a Mario and Luigi exclusive stat, is the luck stat of this game. The higher their STACHE stats are, the greater there is a chance of a Critical or Lucky Hit, which doubles POW. A higher STACHE stat makes the player more likely to receive a hit on a [[Scratch Card]].
|-
|align="center"|[[File:StatHORNMLBIS.png|link=Horn]]
|HORN, a Bowser exclusive stat, functions exactly the same as STACHE does.
|}

===Mario and Luigi's battle system===
[[File:MLBIS Green Shell screenshot.png|200px|thumb|Mario and Luigi battling.]]
The battle system with Mario and Luigi is similar to the battles from the previous games. There are now six categories of attack during battle, as opposed to ''[[Mario & Luigi: Partners in Time]]''{{'}}s five, or ''[[Mario & Luigi: Superstar Saga]]''{{'}}s four. These are Jump, Hammer, [[Attack Pieces]] ([[Bros. Items]]), Items, [[Bros. Badges]], and Escape. The Bros. can defend with their jump and their hammers. The Jump makes Mario and/or Luigi jump to dodge an attack or to counter-attack. The Hammer is used to counter-attack. The music played while battling is the same as the music played during the debut trailer, as seen in the Japanese site.

A new element has been added to battles, a gauge at the bottom of the screen with Mario and Luigi's heads on either end. When Mario or Luigi pull off an action command, that brother's end of the bar fills slightly. When they meet in the middle, it is possible to use a Bros. Badge move. The effect varies with the equipped badge. The normal effect is to restore 20% of both brothers' HP. Badges can be bought in one of the shops in [[Toad Town]]. Some of the badges require that the Action Commands be pulled off perfectly (EXCELLENT is displayed), and some only need GOOD!. An extra block that appears in the battles can be used to swap the badges that brothers use.

===Bowser's battle system===
[[File:MLBIS Bowser inhale.png|200px|thumb|Bowser battling.]]
Bowser has almost the same battle system as Mario and Luigi's, but with a few differences. He has different options: Punch replaces Jump, [[Fire Breath]] replaces Hammer and [[Special Attack (Bowser)|Enemy Attacks]] replace Special Attacks. However, he does not have Bros. Badges. Instead, Bowser gains a vacuum ability after the player advances further through the game. He can swallow enemies with this new ability to make [[Mario]] and [[Luigi]] fight them in his belly. He can also swallow parts of enemies that can restore his HP, raise defense or attack power, or rescue a [[Blitty]]. Bowser's defenses are the Punch and the Shell. Bowser's Punch can counter-attack an enemy, while his spiky shell can hit enemies that try to jump on his head or protect him from attacks.

Enemy Attacks are special attacks that use mostly members of Bowser's army, which are [[Goomba]]s, [[Koopa Troopa]]s, [[Shy Guy]]s, [[Bob-omb]]s, [[Magikoopas]], and [[Broggy]]. These attacks require the stylus to perform. These characters need to be liberated to unlock these attacks.

===Special Attacks===
====Bowser Specials====
[[Bowser]] has six [[Brawl Attack|Special Attack]]s, five of which are obtained via destroying cages contained Bowser's trapped minions.

[[File:Giant Bowser Battle.png|thumb|200px|left|Giant Bowser battling [[Bowser's Castle|Bowser Castle]]]]
At certain points in the game, Bowser gets crushed by a large object such as [[Bowser's Castle]], which leaves him in a dying state. In order to revive Bowser, the Bros. must play a 2D shooter-like minigame in the [[Rump Command]]. When revived, Bowser grows to a giant state. In order to complete these battles, the player must rotate their DS sideways to play. In these battles, Bowser only has three options of attack. Punching requires quickly sliding the stylus across the screen to execute. Fire requires the player to blow into the [[Nintendo DS#Microphone|DS microphone]]. The last option, Healing, requires Mushrooms found within the battle itself. Defending includes an event where the player must tap the touch screen in certain areas to counter-attack, punching to deflect blows, and blowing huge flames at the enemy. After each giant battle, Bowser returns to normal. There are four such battles in the game.

===Equipment===
====Clothing====
{{main|List of clothing in Mario & Luigi: Bowser's Inside Story}}
''Mario & Luigi: Bowser's Inside Story'' differs from its predecessors by including a more varied clothing system. In addition to overalls, Mario and Luigi can wear socks, gloves, boots, and accessories while Bowser can wear shells, arm bands, rings, and fangs. Mario, Luigi, and Bowser can wear additional clothing types if they [[rank]] up from repeated battles.

====Badges====
Badges in ''Mario & Luigi: Bowser's Inside Story'' are used exclusively by Mario and Luigi, and they work differently from its predecessors. Mario and Luigi must successfully perform Action Commands to fill the badge gauge. Once the gauge is filled, players can tap it to receive an effect that benefits them in a variety of ways, which can be changed depending on the type of badge both brothers wear.

In the table, the left side of the badge (Luigi's badge) decides how good the action command must be to fill the bar, and how big the effect will be. The right side (Mario's badge) decides what the effect will be.

==Status ailments==
Many status ailments appear in ''Mario & Luigi: Bowser's Inside Story''. Each type affects the heroes and enemies with their own variables. Many enemies can inflict the diseases, as well as some attacks that the three heroes can learn. To relieve the effects, the player can use a [[Refreshing Herb]] or - depending on the type - can wait for it to run out of their systems.

==Overworld==
While Mario and Luigi adventure through [[Bowser's body]], Bowser is walking around the overworld. Mario and Luigi can influence Bowser. They can pinch nerves to make Bowser panic. They can also touch Bowser's muscles to give him a power-up. Equally, Bowser can change the course of the Mario Bros.' adventure. For example, he can flood them by drinking from a fountain. After a certain point in the game, Mario and Luigi can go to the [[Pipe Yard]] and use [[Warp Pipe]]s to exit Bowser's body and explore the overworld, and then use the pipes to enter Bowser's body again. Bowser can use [[Chakroad]]s to warp between different locations of the Mushroom Kingdom.

Overworld icons have slightly changed. They now display the health of the character. Bowser uses two buttons in the overworld, X to punch, and Y for firebreath. Later in the game, Bowser learns new moves such as a dashing punch, ground-pounding, and curling up into a spikeball (much like the way he attacked Mario in ''[[Super Mario Galaxy]]''). Mario and Luigi use A and B respectively to jump. At one point they gain hammers. Mario can destroy rocks and crates, while Luigi can hit Mario to make him mini so as to reach previously inaccessible areas. Later in the game, the Marios learn new moves such as the [[Spin Jump]] and the Drill Bros. They also encounter items in the overworld that help them perform moves to reach a goal or an item. The items include a gas pump that seems to be shooting out helium. Mario can fill himself up with helium and float into the air like a balloon. If Luigi is to grab his legs at that time, they are able to perform a floating high jump, somewhat similar to the move found in the first installment of the series. They can also find a Blue Koopa shell that Mario can put on. Luigi can whack him with his hammer to shoot Mario over previously inaccessible areas to hit switches. This move is very similar to the move the Koopa companions use in the ''[[Paper Mario (series)|Paper Mario]]'' series. 

While Bowser explores a 3-D overworld, Mario and Luigi explore a 2-D world inside his body, much like a traditional platformer, though they can go into the 3-D overworld at any time once the Pipe Yard is available. The actual overworld is connected just as it was in ''Mario & Luigi: Superstar Saga'', unlike ''Partners in Time''{{'}}s linear levels. The overworld is up to 4-5 times larger than ''Superstar Saga''{{'}}s overworld. The map in this game consists of a beach, a forest, a cape, the road to Bowser's Castle, Toad Town, Bowser's Castle, Peach's Castle, Grasslands, a railroad, underground, and a lake. In the Nintendo Power review, it was stated that there are tons of sidequests, much to explore, and plenty to do in the free roam overworld.

===Shops===
{{Main|List of shops in Mario & Luigi: Bowser's Inside Story}}
Throughout the game, there are several shops where the player can purchase and sell items from several shops on their adventure. Shops available to Mario and Luigi are run by characters and all found in [[Toad Town Mall]] and [[Toad Square]]. Only two shops are available to Bowser: [[Broque Monsieur's Shop]] and [[Broggy's Shop]], both in [[Dimble Wood]]. However, there are [[Shop Block]]s around the Mushroom Kingdom that provides the same functionality to Bowser. There is a [[Scratch Card]] system where the player has a chance to get a part of their coins spent back. The amount of squares that give coins back depends on Mario and Luigi's stache level and Bowser's horn level.

===Beans===
{{Main|List of beanholes in Mario & Luigi: Bowser's Inside Story}}
After Mario and Luigi learn the [[Drill Bros.]] move, they can collect beans from beanholes by tunneling underground and then jumping. There are about 200 beanholes scattered around the world, both in the Mushroom Kingdom and inside Bowser's body. Mario and Luigi can also collect beans from characters like [[Kuzzle]] and the [[PR Toad]] of [[Toad Town Mall]].

==Differences from other ''Mario & Luigi'' games==
While a direct sequel in the ''Mario & Luigi'' series, ''Mario & Luigi: Bowser's Inside Story'' still has several differences compared to the [[Mario & Luigi: Superstar Saga|first]] [[Mario & Luigi: Partners in Time|two]] ''Mario & Luigi'' games.
*This is the first game to feature more than one optional boss stronger than the final boss.
*This is the first game in the series not to feature [[Professor E. Gadd]].
*This is the only game in the series not to feature [[Yoshi (species)|Yoshi]]s.
*This is the only game in the series to feature Bowser as a main protagonist.
*This is the first game in the series where Mario and Luigi can double jump; in battle in the first game, they could not while in the second game, they needed the babies to do it.
*This is the only ''Mario & Luigi'' game to not have any traditional enemies as common enemies, besides derived species which only appear in this game.
*This is the first ''Mario & Luigi'' game to feature an "Excellent!!" rating when completing an attack.
*This is the first ''Mario & Luigi'' game where jump and hammer attacks receive a rating depending on how well timed the attack is. 
*This is the only ''Mario & Luigi'' game to not have a purely snow-, desert-, mountain-, or temple-themed area.
**The [[Airway (Mario & Luigi: Bowser's Inside Story)|Airway]] can be considered a snow- or ice-like area when it is frozen, and [[Plack Beach]] features a mountainous section.
===Gameplay differences===
[[File:Scatchcard.png|200px|thumb|The new scratch card mode, allowing Mario, Luigi, and Bowser to win money back.]]
*This is the first ''Mario & Luigi'' game to have optional bosses, with the exception of three of the four [[Popple]] fights and [[Jojora]] in ''Mario & Luigi: Superstar Saga'', who are not required to be defeated, but can be defeated for extra experience and items.
*Unlike ''Mario & Luigi: Partners in Time'' for the Nintendo DS, this game makes greater use of the DS's touch controls and microphone.
*This is the first game in the ''Mario & Luigi'' series (as well as the fourth RPG overall) to have Bowser as a playable character.
*The player can equip Mario and Luigi with pants, gloves, shoes, socks, and accessories instead of just pants as in the first two ''Mario & Luigi'' games.
*Badges have a different function. Bro. Badge moves can be performed with them. This game contains eight badges, which is notably less than the previous ''Mario & Luigi'' games.
*This is the first of the series to have power-ups or other items in the overworld such as the blue [[Koopa Troopa]] shell.
*This is the first ''Mario & Luigi'' game to have a [[rank]] system. This means, if the player gets at a certain level, they go to a higher rank. Ranks for Mario and Luigi are the Mushroom Rank, Shell Rank, Flower Rank, Shine Rank, Star Rank, and the Rainbow Rank. Bowser's ranks are the Bronze Boss Rank, Silver Boss Rank, Gold Boss Rank, and the Final Boss Rank.
*Mario and Luigi get the [[hammer]]s earlier in ''Mario & Luigi: Bowser's Inside Story'' than in the other ''Mario & Luigi'' games. (An exception is ''Mario & Luigi: Paper Jam'', where they have hammers from the start.)
*The [[Scratch Card]] is introduced, allowing the main characters to earn back coins after spending them.
*This is also the first game where the hammerheads do not fall off in defense when held too long; the bro. just puts it down. Consequently, the hammer can also be held much longer.
*In the first two games of the series, Mario and Luigi use a [[suitcase]] to store anything they collect in their journey. In ''Bowser's Inside Story'', however, they use the [[star menu]], managed by [[Starlow]] in order to access their items.
*This is the first game to have a Boss-Refight or Skill Challenge.
*This is the first time in the ''Super Mario'' [[Genre#Role-playing|RPG]] series that a sequel has been released on the same system as its predecessor.
*This is the second game where the Mario Bros. battle inside Bowser's body, the first being ''Mario & Luigi: Superstar Saga'', where they battle [[Cackletta]]'s Soul inside Bowser. Fawful (who worked for Cackletta) is fought in a similar way to Cackletta. Also, before both battles take place, the player fights an affected form of Bowser. While Mario and Luigi are sucked into Bowser and Cackletta was inside him, for Fawful it is the reverse; Bowser inhales Dark Fawful, and he fights the Mario Bros. inside of Bowser.
*This is the first ''Mario & Luigi'' game where Bowser does not end up possessed by the main villain, as well as the first RPG game since ''Paper Mario'' where the main villain does not actually possess one of the main characters.
**However, [[Dark Bowser]] is a character who has copied Bowser lineaments by gathering his DNA, and is similar to previous Bowser possessions.

===Release differences===
*This is the first ''Mario & Luigi'' game to be released in Japan before any other country.
*This is the first ''Mario & Luigi'' game in which the American box art is the same as the Japanese box art. The European box art, while not exactly the same due to the ratings' graphics requiring the artwork to be rearranged, uses the same artwork (but with Luigi's and Bowser's eyelines changed to reflect their positions) and background as the Japanese box art.
*This is the first ''Mario & Luigi'' game to have multiple languages for its North American release. Both the French and Spanish translations are distinct from those of Europe.

|4.5/5
|"''There's very little in Bowser's Inside Story to not like. It's great to look at, the interaction between the "inside" and "outside" worlds is well thought-out, the mini-games and interactive battles are always a treat to play, and it's probably the funniest Mario & Luigi game yet. The game is long, too. Expect to put in well over 20 hours before you're finished. It may not be a traditional RPG, but it's one of the more enjoyable ones out there.''"

|9/10
|"''Superstar Saga was, very quietly, one of the best games of its generation, sadly appearing too late in the [[Game Boy Advance|GBA's]] lifespan to be much more than a cherished secret. Partners in Time was similarly smart but not quite so engaging, possibly because the inclusion of the Mario babies overburdened the controls while offering too little reward for the extra hassle. That's not the case here, however: the brother's old enemy is a triumph precisely because he provides such a contrast to them: he's a bullish idiot who allows you to enjoy your blunt powers with very few limitations. Inside Story is absolutely a return to form, in other words - and, in the end, you've got Bowser to thank for that.''"

|Craig Harris, [https://www.ign.com/articles/2009/09/10/mario-luigi-bowsers-inside-story-review IGN]
|9.5/10
|"''The Mario & Luigi series has already established itself as a fantastic RPG franchise, and the third game does not disappoint. I have no problem classifying it as the best of the bunch, thanks to an excellent and appropriately surreal script, epic oversized battles, and the fact that Bowser is a playable character and gets most of the gameplay time. Let's hope that this is a jumping-off point for Bowser; this guy really needed a top-billing production!''"

==References to other games==
*''[[zeldawiki:The Legend of Zelda (Game)|The Legend of Zelda]]'' - In [[Toad Town]], Mario and Luigi meet a Toad who teaches them how to dig up special beans. After finishing, he states, "Find all you can. They're a secret to everybody!", in reference to the saying in this game where the Secret Moblin would give Link free Rupees after saying, "It's a secret to everybody."
*''[[Super Mario Bros. 2]]'' - During Bowser's battle with the giant Wiggler, the Wiggler sometimes attacks by pulling out vegetables, which are the same ones that are seen in this game. Also, one of Bowser's brainwashed minions states that he forgot what Bowser's castle was originally called (before it was turned into "Fawful Theater"), and mistakenly referred to it as "[[Mouser]]'s Castle".
*''[[Super Mario RPG: Legend of the Seven Stars]]'' - In addition to the storyline of Bowser attempting to reclaim his castle, Bowser claims [[Starlow|Chippy]] as one of his minions, saying she could "thank him later" (just like when Bowser rationalizes joining Mario's party). In addition, some notes of the [[Forest Maze]] track appear in the Toad Town and [[Peach's Castle]] themes.
*''[[Super Mario Bros. 3]]'' - The starting section of the file select music is similar to the [[P Switch]] and [[Toad House]] theme. [[Sockop]]s are clearly meant to resemble the [[Goomba's Shoe|Kuribo's Shoe]], and at one point Luigi will even hop around inside an unconscious Sockop, allowing him to walk along spikes without taking damage, just as the Kuribo's Shoe does. In addition, one of the Sockops' names is, apparently, Kuribo.
*''[[Dr. Mario (game)|Dr. Mario]]'' - Blue Viruses appear on a poster in Dr. Toadley's office, and in one of the [[Toothy]]'s attacks.
*''[[Super Mario World 2: Yoshi's Island]]'' and ''[[Yoshi's Island DS]]'' - The [[Fawful Guy]] enemy can imitate the attack patterns of both the [[Woozy Guy]] and the [[Glide Guy]]. In addition, one of its attacks mirrors Yoshi's main form of offense in the game, egg throwing.
*''[[Super Mario 64]]'' - The music that plays within Peach's Castle when visiting it for the first time is a variation of its theme here.
*''[[Super Mario Sunshine]]'' - One of the brother's ranks is called the Shine Rank.
*''[[Paper Mario]]'' - The Koopa Paratroopa Trio in the game wear sunglasses, similar to this game. The blue Koopa shell power-up in the overworld is similar to [[Kooper]]'s field ability. Also, Princess Peach using her combined powers with Starlow references [[Peach Beam]].
*''[[Mario & Luigi: Superstar Saga]]'' - Fawful reappears as a villain. The way Bros. Attacks are used from this game is reused, and there is a slight remix of [[Cackletta]]'s theme song that played in the background after Fawful took over Peach's castle. Additionally, the statues of Fawful in Bowser's castle depict his outfit from his rematch in this game. Mario and Luigi battle Dark Fawful inside of Bowser's body, just as they did with Cackletta. The chair seen near the [[Conference Room]] has the same design (seen only briefly in the beginning of said game). Also, the [[Mini-Mario|Mini Mario]] and [[Spin Jump]] abilities return.
*''[[Mario & Luigi: Partners in Time]]'' - In the instruction manual for this game, Mario, Luigi, and Princess Peach's artwork was reused. When Mario and Luigi talk to Broque Madame, she tells them stories about the Shroob invasion that took place in the game. Several Shroobs are also seen at Bowser's castle, where they were kept frozen in a cryogenic chamber. If the player chooses to thaw them out, then an optional boss battle with them will commence. During the battle, several other Shroobs, including the [[Elder Princess Shroob]] can be seen in the background. After the battle, Mario and Luigi tell Starlow about their previous battle with the Shroobs, and how they defeated them while they were babies. While the audience is still in the theater in Bowser's castle, a Shroob can also be found sitting in the audience on the bottom right. Also, there is a boot called the Shroob Boots. Fawful Guys, which are fought by Mario and Luigi in [[Bowser Path]], have an attack in which they are pulled offscreen by a tongue (during which the same roar heard from [[Yoob]] is heard), and are thrown at either one of the bros. in the form of an egg, which highly resembles one of [[Sunnycide]]'s attacks.
*''[[New Super Mario Bros.]]'' - [[Blue Shell]]s make a reappearance, as does [[Shell Mario]]. A Mega Mushroom also occasionally appears during one of Broque Monsieur's attacks in his tutorial. Additionally, a single [[Squiggler]] appears as an NPC in Dimble Wood.
*''[[Super Paper Mario]]'' - Bowser's battle animation resembles the one in this game.
*''[[Super Mario Galaxy]]'' - Spike Ball, the ability where Bowser curls into a ball, heavily resembles an attack that Bowser uses during his fights against Mario/Luigi.

==References in later games==
*''[[Mario & Luigi: Dream Team]]'' - [[Starlow]], [[Broque Monsieur]], [[Broque Madame]], [[Broggy]], [[Private Goomp]], [[Corporal Paraplonk]], and [[Sergeant Guy]] all return to this game. Bowser's appearance in this game makes multiple references to ''Mario & Luigi: Bowser's Inside Story''. He uses the Punch and Spike Ball moves in a battle, and can inhale in cutscenes. A cutscene prior to fighting giant Bowser has him say "SHOWTIME!" Also, Bowser's theme and the game's boxart style are reused.
*''[[Super Smash Bros. for Wii U]]'' - The songs "Tough Guy Alert!" and "The Grand Finale" return in this game.
*''[[Nintendo Badge Arcade]]'' - One of the badges in the Pixel Collection set depicts the ''Mario & Luigi: Bowser's Inside Story'' game card.
*''[[Super Smash Bros. Ultimate]]'' - The songs "Tough Guy Alert!" and "The Grand Finale" return in this game. Fawful, Starlow, and Broque Monsieur (using their respective artwork from this game) appear as [[Spirit (Super Smash Bros. Ultimate)|spirits]]. [[Piranha Plorp]]s are mentioned in [[List of Palutena's Guidance conversations#Piranha Plant|Palutena's Guidance]] for [[Piranha Plant]].
*''[[Mario & Luigi: Brothership]]'' - The [[Jump Helmet]] and [[Yoo Who Cannon]] both return as [[Bros. Attack]]s for Luigi. Bowser calls Starlow "Chippy", the nickname originating from ''Bowser's Inside Story''. Additionally, the [[Treevil]] has a new wire variant, the [[Krode]].
