Mario & Luigi: Bowser's Inside Story (JP) (KO) (also called M&LBIT, Mario & Luigi RPG 3, or Mario & Luigi 3) is the third installment in the Mario & Luigi series and the second to be released on the Nintendo DS.

It was developed by AlphaDream and featured, for the first time in the series, Bowser as a playable character, with the babies from Mario & Luigi: Partners in Time no longer present. The game was announced at E3 2009.

The game was later remade for the Nintendo 3DS in December 2018 in Japan and 2019 worldwide under the name of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. Outside Japan, the release year marks the 10th anniversary of this game.


After the Mushroom Kingdom's citizens start contracting the blorbs, a disease that swells Toads, Princess Peach holds a conference meeting, which includes Mario, Luigi, Toadbert, Toadsworth, and a Star Sprite named Starlow. Bowser crashes into the room in his attempts to join the meeting and is sent flying out of Peach's Castle after easily being defeated by Mario. While in Dimble Wood, Bowser comes across a cloaked merchant, who is Fawful in disguise, that gives him a "Lucky Mushroom" that causes him to inhale his surroundings, in which this ability is used to suck in the characters attending the conference at Peach's Castle.

Mario, Luigi, and Starlow reawaken inside the Trash Pit area of Bowser's body, where they use their acquired hammers to hit an exposed nerve and rouse Bowser, who had been dumped in Cavi Cape Cave. Starlow, who talks to Bowser throughout the game under the alias "Chippy", withholds information surrounding the Mario Bros.'s whereabouts and assists him in remembering the past events. Bowser then 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, where Midbus wins against him and abandon him.

Bowser helps a stranded Broque Monsieur get back on Plack Beach, where Broque rewards Bowser 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 bug that was blocking Bowser's fire breath at the Flame Pipe. 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 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 then defeat it in battle.

Midbus dodges Bowser's Banzai Bill by launching the castle and landing it on Bowser. The Mario Bros. revive him from the Rump Command, which unintentionally turns Bowser as giant as the castle. After Bowser defeats the castle, it flies away with Bowser 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 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.

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. He meets up with some 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 Caves 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 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 Cures 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 barrier of Boo Blocks, stopping the Mario Bros. in their tracks.

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 the maze beyond them, allowing them to track down Durmite, whose 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. were now under Fawful's control and had built a railway straight through the vault. They use their train to ram Bowser out of the castle and into a boulder, resulting in another emergency revival and 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 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 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, Mario and Luigi 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 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.

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 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 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 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 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 show a montage of still images showing that Bowser loses the ensuing fight.

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 is alone does Bowser open the package, revealing a thank-you cake with himself, 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 will just start from the last save point, before the final battle.



The overworld for Bowser, and the Mario Bros. are different. Mario and Luigi actually travel inside Bowser's body in a sidescrolling setting reminiscent of classic Mario platformers. Each section inside Bowser's body is small and the brothers can easily traverse the body via the map. However, in one pint during the game, the Bros. gain the ability to traverse outside of Bowser's body and move in any direction.

When controlling Bowser, on the other hand, the player is given much more freedom. Rather than be constricted to only left and right, the player can go in any direction they wish. Oftentimes Bowser will be too weak to perform a certain action such as pulling something towards him, so the brothers will be required to enter a certain part of his body and stimulate body parts (such as muscles) so that he'll be given enhanced abilities. Occasionally an event will occur in Bowser's body that will prevent him from performing actions that he normally can such as breathing fire, so the brothers will have to inspect his body and find what's wrong and fix it.


Battles will be triggered when either the Mario Bros. or Bowser touches an enemy. There are no random enemies in the game. Fighting enemies and consequently defeating them will result in experience points. Once you receive a certain amount of experience points, your character will level up. After each level up, the amount of points he'll need in order to level up again will rise.

Battles are turn based as in the previous titles. Mario and Luigi will fight together during battles but Bowser will fight alone. Like on the world map, the A and B buttons are both assigned to Mario and Luigi. During the course of the game the player will find special attack parts that will give the characters special attacks. These special attacks can be found in blocks marked with an "A", though Bowser's parts can be collected by saving his minions and Blitties. Each of the attacks use SP, which can be refilled by using Syrup.

Fighting with Mario and Luigi is similar to the other titles. The player chooses an action for each character from six different categories, and following this they'll execute the action, whether it be to attack an enemy, escape, or use an item. Attacks can become more potent by pressing either the A or B button (depending on the character) at the exact moment that they connect with the enemy.

For example, if Mario is assigned to jump on a foe, the moment his shoe touches the enemy the player is required to press the A button in order to deliver more damage than he normally would. A new option is available called Bros. Badges. As in previous games, badges can be purchased in shops and found throughout the game's world. In this game, when each brother's bar during battle meets in the middle, they are able to execute a command that will benefit them. The bars only increase when they are able to time their attacks so that they deliver more damage.

Special Attacks

There are two special attack genera that can be encountered in the game: Bros. and Brawl attacks.

Attack Cost Obtained by Operation Targets...
Bowser Specials (Brawl Attacks)
Goomba Storm* 6 SP Freeing the Goombas in Dimble Wood. The Goombas charge their target and Bowser has to burn them with his fire breath to power them up. This targets a single enemy by default, but killing the target causes the move to target another random enemy.
Shy Guy Squad 8 SP Freeing the Shy Guys in Bowser Path. Bowser enters his shell and the Shy Guys roll Bowser Back to send him flying into his target. Press X to kick for more damage. This move targets a single enemy.
Koopa Corps 10 SP Freeing the Koopas in Blubble Lake. The Koopas charge their target and Bowser has to kick them back. Drag his body to change his position. This targets all enemies at random.
Bob-omb Blitz 12 SP Freeing the Bob-ombs in Bowser Castle. The bob-ombs light their fuses and Bowser directs their paths. The player can choose Bowser's target.
Magikoopa Mob 15 SP Freeing the Magikoopas in Peach's Castle. The Magikoopas go on the offensive with their spells as Bowser powers them up with his magic. This targets all enemies at random.
Broggy Bonker 20 SP Finding all 15 Blitties and giving them to Broque Monsieur. Bowser cleans Broggy to power him. Broggy roughs up his enemy and then charges from behind with the same moves he used as a boss. This targets a single foe by default, but if he kills the enemy Bowser instructed him to kill, Broggy changes targets.
Mario & Luigi Specials (Bros. Attacks)
Green Shell* 3 SP Finding all 10 attack pieces in Trash Pit. The Bros. kick a Green Koopa Shell toward their target. This targets a single foe by default, but switches to another random enemy if the Bros. kill their target.
Fire Flower 4 SP Finding all 10 attack pieces in Pump Works. The Bros. use a Fire Flower to enter their Fire Forms and throw fireballs at the target. Press the button of the Bro. whose hand has the bigger fireball. This targets all enemies at random.
Jump Helmet 6 SP Finding all 10 attack pieces in Flab Zone. Luigi advances with a golden spring-loaded Koopa Shell on his head as Mario jumps off him towards his target and attacks with a dropkick. This move targets a single enemy.
Yoo Who Cannon* 7 SP Given by the Blue Paratroopas after Mario & Luigi learn how to use Blue Shells. Mario and Luigi hide in barrels that launch them at full speed. Remember which Bro. is in each barrel and press his button. If you get it wrong, the move is botched. This targets foes randomly, striking up to eight.
Super Bouncer 7 SP Finding all 10 attack pieces in Energy Hold. Mario launches a giant ball and Luigi tries to get to the top. Luigi them must smash his target with B and Mario must launch the ball again. This move targets a single foe, but can collide with a different target through random chance. If the Bros. kill their target, the move will target foes randomly.
Mighty Meteor* 8 SP Given by Dr. Toadley's intern after the Dark Star's blockade is destroyed. Mario and Luigi launch the Mighty Meteor towards their target with their hammers. Hold to power up. This targets foes randomly, up to four.
Spin Pipe 10 SP Solving Kuzzle's first puzzle at his house at Plack Beach. Mario and Luigi enter the Spin Pipe and strike their target in rhythm. This targets a single foe by default, switching to a different foe if that target dies.
Snack Basket* 14 SP Finding all 10 attack pieces in Dimble Wood. Luigi eats food, causing his body to grow huge. Mario then launches him into the sky with A. Press B to have Luigi slam his body onto the floor. When he lands, he creates a shockwave. This targets all the grounded enemies and damages them all at once.
Magic Window 18 SP Defeating the optional Shroob boss at Bowser Castle. The Bros. dropkick their target from windows. This targets all enemies at once, but flubs if a Bro. attacks a spiny foe.
Falling Star 20 SP Finding all the 10 attack pieces in Peach's Castle (seven are found in one particular block, while the other three are found in invisible blocks, marked on the map). The Bros. throw Stars to power the Falling Star. This targets a single enemy.

(*) = required


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 only game in the series to feature Bowser as a main protagonist.
  • This is the first Mario & 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 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 only Mario & Luigi game to not have a snow, desert, mountain, or temple-themed area.

Gameplay differences

  • This is the first Mario & Luigi game to have optional bosses that do not need to be faced at all. The first instance was 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 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 hammers earlier in Mario & Luigi: Bowser's Inside Story than in other Mario & Luigi games.
  • 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 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 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.


Mario & Luigi: Bowser's Inside Story has received critical acclaim, with a score of 91.01% based on 47 reviews on GameRankings[1] and a 90 based on 58 reviews on Metacritic[2], making it the highest-rated out of the Mario RPG games. Much of the game's praise was directed towards its gameplay, humor, storyline, integration of Bowser as one of the main protagonists, and innovative use of the Nintendo DS' capabilities.


Bowser's Inside Story has sold 3.81 million copies worldwide as of April 2016,[3] making it the best-selling RPG in the Mario franchise.

Mushroom Kingdom Tribune

The Mushroom Kingdom Tribune is a promotional newspaper sent by Nintendo via e-mail. This newspaper includes information about the release of Mario & Luigi: Bowser's Inside Story.
