'''''Mario & Luigi: Bowser's Inside Story''''' (known in Japan as '''''Mario & Luigi RPG 3!!!''''') is a [[Nintendo DS]] game developed by [[AlphaDream]] and published by [[Nintendo]]. It is the third title in the [[Mario & Luigi series|''Mario & Luigi'' series]], preceded by ''[[Mario & Luigi: Superstar Saga]]'' for the [[Game Boy Advance]] and ''[[Mario & Luigi: Partners in Time]]'' for the [[Nintendo DS]], and succeeded by ''[[Mario & Luigi: Dream Team]]'' and ''[[Mario & Luigi: Paper Jam]]'' for the [[Nintendo 3DS]]. Unlike its predecessor, this game makes much greater use of the DS touch controls and microphone.

==Story==
[[File:Bowser's Inside Story ToadBlorbs.png|thumb|The Blorbs being discussed.]]
After the [[Mushroom Kingdom]]'s citizens start contracting the [[Blorbs]], a mysterious disease that swells [[Toad (species)|Toads]] to gigantic proportions, [[Princess Peach]] holds a conference meeting to find a solution for the problem. [[Mario]], [[Luigi]], [[Toadbert]], [[Toadsworth]] and a Star Sprite named [[Starlow]] are all in attendance. [[Bowser]] crashes in uninvited, and when his temper fires up, he has to be defeated by Mario and sent flying out of the castle by Peach and Starlow. Bowser awakens in [[Dimble Wood]] and eventually comes across a mysterious cloaked merchant who gives him a so-called "[[Vacuum Mushroom|Lucky Mushroom]]", but when he eats it, he begins inhaling everything in sight. The figure is revealed to be [[Fawful]], who brings Bowser back to Peach's castle, where he inhales all the conference-goers and passes out.

Mario reawakens inside the [[Trash Pit]] area of [[Bowser's body]], soon finding Starlow and Luigi, and using some newly-found hammers to hit an exposed nerve and rouse Bowser, who had been dumped in [[Cavi Cape Cave]]. Deciding not to tell Bowser that the Mario Bros. are inside him, only Starlow speaks to him (eventually under the alias "Chippy") in an attempt to figure out what happened, but Bowser cannot remember. Bowser makes his way outside and encounters Fawful, who explains that the Blorbs and the Vacuum Mushroom he gave Bowser were all part of a plan to conquer both the Mushroom Kingdom and [[Bowser's Castle]]. He then has his minion, [[Midbus]], battle Bowser, who is unable to breathe fire or fight effectively, bringing the battle to an early close as the villains simply leave the weakened Koopa King to "work on [his] skills".

Incensed, Bowser sets out for his castle. Travelling along [[Plack Beach]], he helps [[Broque Monsieur]] get back to shore after the piece of land he was on floated away - a feat made possibly by the Mario Bros. powering up Bowser from the inside. As a reward, Broque gives Bowser a [[Vacuum Block]], allowing him to control his sucking abilities. After defeating the [[Sea Pipe Statue]], Bowser drinks some water which causes changes in his body, allowing Mario and Luigi to enter [[Pump Works|a new area]] and defeat the [[Scutlet (boss)|Scutlet]] bug that was blocking Bowser's fire breath. After subduing Broque's rambunctious pet dog [[Broggy]], Bowser enters Dimble Wood, where he eventually comes across [[Sergeant Guy]], [[Corporal Paraplonk]], and [[Private Goomp]]. The trio are planning to retake Bowser's castle with a [[Banzai Bill]] launcher, but it falls to Bowser to find ammunition. He tries to procure a giant carrot as a makeshift missile, but the Wiggler who had been growing it makes Bowser eat it instead and then attacks him, yielding up an actual Banzai Bill upon his defeat. On his way back to his minions, Bowser is overcome with stomach pain, and Mario and Luigi discover that he had eaten a large worm-like creature named [[Durmite]] along with the carrot; they defeat it in battle and it surprisingly shrinks and runs off.

Bowser returns to the cannon and fires the Banzai Bill at his enemy-occupied castle, however Midbus flies the rocket-powered building over the incoming missile and lands it on Bowser. The Mario Bros. revive him with adrenaline from the [[Rump Command]], which has the unintended side-effect of turning Bowser as giant as the castle, which he then fights off with his bare hands. The castle flies away and Bowser gives chase, travelling through [[Bumpsy Plains]] and [[Bowser Path]] to reach his destination. Midbus launches a giant iron ball at Bowser, but he throws it back, knocking the castle out of the air and back onto its moorings for the last time. Entering the castle, Bowser discovers that Fawful has turned it into a theater and brainwashed all the Koopa Troop members 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 processm which sends him blasting off back to Cavi Cape. 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 into unconsciousness.

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 Tunnels]] themselves and try to head off 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 [[Doctor 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. 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. 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 barrier of [[Boo Block]]s, stopping the Mario Bros. in their tracks.

[[File:Booraymachine2.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 blocks to disappear and help Mario and Luigi navigate [[Energy Hold|the maze beyond them]], allowing them to track down Durmite, whose reveals herself to be a sage named [[Wisdurm]]. She battles them over the Star Cure, turning to a butterfly after her defeat 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 only to find that the Monty Bros. were now under Fawful's control and had built a railway straight through the treasure vault. They use their [[Fawful Express|train]] to push Bowser out of the castle bowels and into a boulder, resulting in another emergency revival and giant battle between Bowser and the train. Returning to his vault after wining the fight, Bowser realizes that he's 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 ML|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|gut]] by the Mario Bros.

Mario and Luigi return to Toad Town and are sent after the final Star Cure by 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 refuses to give them the Star Cure unless they can knock him out of the pose he has held for a thousand years. After a cryptic hint from Chakron, Mario and Luigi head for Dimble Wood to collect Attack Pieces for the ground-shacking [[Snack Basket]] move, but Mario is kidnapped by a [[Sockop]] and has to be rescued by Luigi, who wears a knocked-out Sockop like a [[Kuribo'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:Miracle Cure.PNG|thumb|left|The Miracle Cure curing the blorb-infected Toads.]]
Back at the clinic, Doctor 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 sucking up Peach and then 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 and floating 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 Castle|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 get away, but is absorbed by the Dark Star, allowing 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 confirmed by Bowser, who aims to collect 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, defeat 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 forever.

Inside Bowser, Fawful is then revealed to be on his way out, and with a dying grin, he attempts to take the Mario Bros. with him in a final explosion of his own, but all this accomplishes 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 Bowser into a complete rage. The Toads and the Princess flee from the scene, and the credits roll over 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 the Koopa Troop in helping with the repairs, and only once he is sure he's alone does Bowser open the package, revealing a thank-you cake with himself, Mario, Luigi, and Peach on it. 

As in the other two ''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 will just start 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 instalment, 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 later instalments 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 [[Mustache|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. 

*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).
*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.
*POW, or '''Pow'''er, is how strong the fighter is. POW determines how much damage they can inflict.
*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.
*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.
*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 Lucky Hit, which doubles POW. A higher STACHE stat makes the player more likely to receive a hit on a [[Scratch Card]].
*HORN, a Bowser exclusive stat, functions exactly the same as STACHE does. The only difference is in the name of the stat.

===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 previous titles. 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's 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 (Mario & Luigi: Bowser's Inside Story)|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]]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.

===Giant Bowser Battle System===
At certain points in the game, Bowser gets crushed by a large object such as [[Bowser's Castle]]. 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 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.

==Ranks==
[[File:Rankupbis.png|thumb|200px|Mario elevated to Shell Rank.]]
When leveling up Mario and Luigi, and Bowser occasionally reach a [[rank]]. When this happens new criteria is added to the game such as being able to equip more clothing or being able to shop at certain places. Here is a list of the ranks:

''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 Ailment]]s 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 wrap 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. 

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.

===Beans===
{{Main|List of bean spots in Mario & Luigi: Bowser's Inside Story}}
After Mario and Luigi learn the [[Drill Bros.]] move, they can collect bean from bean spots by tunneling underground and then jumping. There are about 200 bean spots 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 first 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]], or [[Yoshi]].
*This is the first game in the ''Mario'' series to feature Bowser as a main protagonist.
*This is the first Mario and Luigi game to give Mario and Luigi's in-game sprites eyebrows.
*This is the first game in the series where Mario and Luigi can double jump; in battle in the first game they couldn't while in the second game they needed the babies to do it.
*This is the only ''Mario & Luigi'' game to not have regular [[Goomba]]s as enemies.
*This is the only ''Mario & Luigi'' game to not have a snow, desert or mountain-themed area.

===Gameplay differences===
*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.
[[File:Scatchcard.png|right|thumb|The new scratch card mode, allowing Mario, Luigi, and Bowser to win money back.]]
*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]] shell.
*This is the first ''Mario & Luigi'' game to have a [[rank]] system. This means, if the player gets at a certain level, they will 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 other ''Mario & Luigi'' games.
*[[Scratch Card|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 don't 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 in 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 ''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, uses the same pictures 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.

==References to other games==
*''[[Super Mario Bros. 2]]'': During Bowser's battle with the giant Wiggler, the Wiggler sometimes attack 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 states that [[Starlow|Chippy]] could be an honorary member of the [[Koopa Troop]], and 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]]'': [[Sockop]]s are clearly meant to resemble the [[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 blue Paratroopas in the game wear sunglasses, similar to this game. Also, Princess Peach using her combined powers with Starlow references [[Peach Beam]].
*''[[Mario & Luigi: Superstar Saga]]'' - Fawful reappears as a villain. The Bros. Attacks from this game are reused, and there is a slight remix of [[Cackletta]]'s theme song that played in the background after Fawful took over Peach's castle. 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. The music that plays when visiting Peach's Castle in the beginning is a remix of the theme heard in Toad Town before boarding the [[Koopa Cruiser]].
*''[[Mario & Luigi: Partners in Time]]'' - 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 [[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. The theme that plays in Peach's Castle at the beginning is a remix of the present Peach's Castle theme of this game.
*''[[New Super Mario Bros.]]'' - [[Blue Shell]]s make a reappearance. A Mega Mushroom also occasionally appears during one of Broque Monsieur's attacks in his tutorial.
*''[[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.
*''[[Super Smash Bros. for Wii U]]'' - The songs "Tough Guy Alert!" and "The Grand Finale" return in this game.

==Pre-release and unused content==
{{main|List of Mario & Luigi: Bowser's Inside Story pre-release and unused content}}
Some enemies have an attack pattern for [[Mario]] and [[Luigi]], even if they do not face them in the game. There are also several unused voice clips for [[Yoshi]], coming from ''[[Yoshi's Story]]''; there are also unused music from ''Mario & Luigi: Partners in Time'', although it won't play correctly. Early screenshots also show [[Treevil]]s being battled at [[Plack Beach]].

==Glitches==
{{main|List of Mario & Luigi: Bowser's Inside Story glitches}}
If the player does more than 10,000 damage to an enemy then the game will freeze. Also, before the fight with [[Scutlet (boss)|Scutlet]] if the players re-enter the [[Pump Works]] and hit the Save Block the message will say that Bowser can breathe fire again, even though the Flame Pipe is still blocked.

==Staff==
{{main|List of Mario & Luigi: Bowser's Inside Story staff}}
The game's producers were Toshiharu Izuno, Akira Otani and Yoshihiko Maekawa, with [[Shigeru Miyamoto]] and [[Takashi Tezuka]] acting as senior producers and [[Satoru Iwata]] and Tetsuo Mizuno acting as executive producers.

==Trivia==
*The title of the game is a parody on the term "inside story", meaning 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 parody on the famous novel ''A 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''.
*Bowser's icon for swimming when underwater is also Mario and Luigi's jump icon.
