The first game in the ''[[VideoGame/MarioAndLuigi Mario & Luigi]]'' series, released in 2003 for the GameBoyAdvance, and Wii U E-Shop April 2014.

In one of the most elaborate (original) games made for the Game Boy Advance, [[SuperMarioBros Mario]] is sent to the Beanbean Kingdom, which conveniently adjoins the Mushroom Kingdom. Luigi reluctantly goes along after Mario and Bowser [[EnemyMine join forces]]. The BigBad Cackletta reportedly has stolen Princess Peach's voice (yes, her voice) in order to activate the Beanstar, an artifact with the power to grant wishes.
----
!!Tropes appearing in this game:
* AbsurdlyHighLevelCap: Level 99.
* AccidentalMisnaming: Characters invent names for Luigi, because WhoIsThisGuyAgain
* ActionInsuranceGag: At the end of the early gameplay scenes, Bowser's Koopa Cruiser is destroyed by Fawful. Talking to one of the Koopa Troopas found afterwards yields the comment, "The K-Koopa Crusier... We haven't finished... paying it off.."
* AdiposeRex: Queen Bean is a rare female example.
* AnimateInanimateObject: The Chuckolator, an animated barrel of soda.
* ApatheticCitizens: One of the Beanbean Castle Town residents asks you to find his pets for him once the town's started to rebuild from the attack. He tells you the little critters "aren't super-motivated, so they're probably still around town someplace". He seems to be of a type since he can't be bothered to go find them himself.
* ArtisticLicenseEconomics: At the start of the game, the exchange rate between Mushroom Kingdom coins and Beanbean coins is pretty shabby, something like 100M = 10B. Later on, Prince Peasley cockily bets 99,999,999,999,999 Mushroom Kingdom coins that he'll find the PlotCoupons first; even with the poor exchange rate this is a pretty sweet deal. But when he makes good on the bet at the end of the game, the converted value of his promised ante is...99 Beanbean coins, meaning that over the course of a single game, the Mushroom Kingdom's economy has crashed so irretrievably that statistically, even the ''houseflies'' are begging for change in the streets of the nearest stable economy (probably Beanbean). Although it does take MoneyForNothing to its logical conclusion.
* AttackItsWeakPoint: Trunkle's tree on its head, as using several bros attacks on it can take it out before it is able to divide.
* BalefulPolymorph:
** [[spoiler:Prince Peasley]] was turned into a dragon and trapped inside an egg before the game's events began - the dragon is a ''very'' early boss fight. Apparently Mario and Luigi beating the stuffing out of the dragon breaks the spell. Later, he gets shrunken down and eaten by a Pirahna Plant.
** There's also the matter of the Woohoo Hooniversity professors being turned into Laser Snifits.
* BarrierChangeBoss: Mom Piranha's elemental weakness changes depending on her color, and is healed if hit by the wrong element.
* BerserkButton: Jojora doesn't react well when you attack her friends. On the other hand, she doesn't seem to mind too much being attacked herself, as she has killer defense.
* BetaCouple: Toadsworth and Lady Lima.
* BigBad: Cackletta.
* BishieSparkle: When Prince Peasley flips his hair, [[UpToEleven the entire screen goes white]]. Downplayed on one occasion [[spoiler:due to the prince being shrunken]].
* BodyHorror:
** The fate of the professors at Woohoo Hooniversity.
** As well as [[spoiler:Bowletta]].
* BookEnds: The first time you see the Bean-Bean Kingdom, it's been destroyed. Towards the climax, when you come back, it's been destroyed again.
* BossBonanza: The game has [[spoiler:a separate boss fight for each of the seven Koopalings in Bowser's Castle, followed by Fawful, Bowletta, and the Essence of Cackletta.]]
* BreakingTheFourthWall: One of the DummiedOut scenes in Starbeans Café has Wario say "Now that I’m here, this game’s finally gettin’ good!" and later "Don’t you have free drinks for celebrity guest stars in this game?".
* TheBusCameBack: [[spoiler:The Koopalings]] return, after being absent for more than a decade since ''SuperMarioWorld''. Then they get PutOnABus again until 2009.
* ButThouMust: Quite possibly one of the most infuriating examples is The Hammerhead Bros.' tutorial. Which you ''have'' to sit through even if you've mastered how the hammer works.
* ButtMonkey: Poor [[spoiler:Bowser]]. Let's see, during this game, he [[spoiler:gets [[CurbStompBattle curbstomped]] by Fawful, gets stuck in a cannon, gets fired out of it, hits his head so hard he loses his memory, works as [[GoldfishPoopGang Popple]]'s lackey for some time as "Rookie", finally regains his memory but falls who-knows-how-far from the Beanstar, gets possessed by Cackletta, gets his castle blown up, gets beaten up by the Mario Brothers, then finally gets blown up ''with'' the castle and hits the screen, and is then dragged home by the plane and [[ArsonMurderAndJaywalking it's implied that he got a cold]]. He's not gonna try to kidnap Peach for ''a while''.]]
* CaptainErsatz: Popple is suspiciously similar to [[VideoGame/SuperMarioRPG Croco.]]
* ChekhovsGunman: [[spoiler:Remember Blablanadon from the Hoohoo areas? He's the only way to access Bowser's Castle at the end of the game.]]
* CloudCuckooland: Beanbean Kingdom, full stop.
* CognizantLimbs:
** [[spoiler:Cackletta's arms and head need to be destroyed before her heart can be targeted.]].
** Also, [[spoiler:you have to smack Queen Bean's arms for her pointy crown to fall off, but you can bypass all that if you've learned Splash Bros. Advance.]]
** There's also Hermie III, whose claws can be targeted. He'll counter every attack used against him with his claws if his claws aren't down.
* CollectionSidequest: Finding all the coffee beans.
* TheComputerIsACheatingBastard: One Toad in Little Fungitown is playing an arcade game like this.
* CombinationAttack: The main draw of the game is the way Mario and Luigi team up for puzzles and fighting. In all their Bros Moves are the Splash Bros, Chopper Bros, Fire Bros, Bounce Bros, Knockback Bros, Thunder Bros, Swing Bros, Cyclone Bros.
* ContinuityNod:
** Geno from ''VideoGame/SuperMarioRPG'' shows up to teach you how to play the SurprisinglyEasyMiniquest.
** Upon defeating Popple in his final battle, [[spoiler:Birdo TurnsRed and declares that "this is as far as you go!" This is the same line she would open her boss battles with in the ''Super Mario Advance'' version of ''VideoGame/SuperMarioBros2''.]]
* CrossDresser: Luigi dressing up as Princess Peach (even doing a NoblewomansLaugh, if only to conceal his mustache).
* CurbStompBattle: At the start of the game, Fawful does it to Bowser of all people. He literally one-shots Bowser with an attack that would otherwise take 5 or so hits to defeat a Bro.
* DangerouslyGenreSavvy: Cackletta is an ''incredibly'' competent villain for someone out of the ''MarioBros'' series. Notably, she started the trend of Bowser being an IneffectualSympatheticVillain, which took him until ''VideoGame/MarioAndLuigiDreamTeam'' to recover from.
* ADayInTheLimelight: Luigi gets his moment to shine during a few plot points.
* DefeatEqualsExplosion: This happens to all the bosses, even if they are alive in the cutscene that follows.
* DefeatMeansFriendship: To an extent. After Tolstar is defeated, he reappears when the Brothers are cornered and accused by a group of Beanbean guards, vouching for your innocence.
* DiscOneFinalBoss: Cackletta the first time you face her, and she has somewhat nasty attacks to boot.
* DiscOneFinalDungeon: Woohoo Hooniversity houses the fight with [[DiscOneFinalBoss Cackletta]] stated above...and interestingly the second showdown with [[GoldfishPoopGang Popple and Rookie]].
* DistressedDamsel: In an unique twist, Princess Peach isn't kidnapped... but her ''voice'' is. [[spoiler:Well, she still gets kidnapped later, but it isn't the usual "whole game" deal.]] Even then, [[spoiler:it's not Peach's voice that's kidnapped. It's ''Birdo's''. Apparently, anyone can put on a pink dress and a wig and pass for Princess Peach, since Birdo, Luigi and even an ''[[VideoGame/MarioAndLuigiPartnersInTime alien]]'' do it throughout the various ''Mario & Luigi'' games.]]
* DoomyDoomsOfDoom: Fawful's infamous "Mustard of Doom".
* TheDragAlong: Luigi at first.
* TheDragon: Fawful.
* DropTheHammer: Mario and Luigi get hammers after the second dungeon, and they are upgraded twice over the course of the game.
* DualBoss: Popple and his various sidekicks.
* DummiedOut: The game code contains dialog for several different characters giving you the different accessories from [[ItemCrafting mixing bean juice]]: [[VideoGame/WarioLand Wario]] for the Greed Wallet, [[{{Metroid}} Samus Aran]] for the Power Grip, [[Franchise/TheLegendOfZelda Link]] for the Great Force, [[VideoGame/StarFox Fox McCloud]] for the Bonus Ring, [[VideoGame/{{Pikmin}} Captain Olimar]] (who speaks in boxless dialogue) for the Cobalt Necktie, and the racer from [[VideoGame/{{Excite}} Excitebike]] for the Excite Spring. [[VideoGame/LuigisMansion Professor E. Gadd]] would only show up to deliver the Game Boy Horror [[http://themushroomkingdom.net/mlss_lost.shtml TMK has the scripts for the lost cameos.]]
* EmbeddedPrecursor: ''Superstar Saga'' includes the Game Boy Advance port of the ''VideoGame/MarioBros'' arcade game. It's the same port included with the ''Super Mario Advance'' games.
* EnemyMine: Bowser. However, he helps the brothers only because he doesn't like ''other'' bad guys taking what he wants. Sadly it doesn't last long though, as throughout the whole game [[ArbitraryHeadcountLimit events conspire to prevent him from helping]] for anything other than getting to the Beanbean Kingdom.
* EscortMission: Escorting Princess Peach through Teehee Valley to Little Fungitown. You have to keep her onscreen at all times, make sure there are no enemies heading towards her, and work quickly to open the gate at each section of the valley. If you don't do one of the first two, she gets kidnapped. Mario and Luigi must rescue her and try again. However, the player can make this easier by defeating every opponent on the field, then escorting Peach.
* EvenEvilHasStandards: Popple helps Mario move the Beanstar out of harm's way and bows respectfully to him before a battle.
* EvilLaugh: Cackletta tends to...well, [[ExactlyWhatItSaysOnTheTin look at her name]]. Fawful also has one.
* EvilTastesGood: Fawful.
* ExcusePlot: Probably the most notable [[AvertedTrope aversion]] in the entire ''Franchise/SuperMarioBros'' series. The game has ''several'' major {{Plot Twist}}s and features a GambitPileup that doesn't get fully resolved until after the penultimate dungeon.
* {{Expy}}: The Beanstar is pretty similar to [[VideoGame/{{Pokemon}} Jirachi]]...
* FaceHeelTurn: [[spoiler:Birdo, after falling in love with Popple (if it is the same Birdo).]]
* [[FinalExamBoss Final Exam Dungeon]]: [[spoiler:Bowser's Castle.]]
* FingerSnapLighter
* FingerlessGloves: Sniper Bills.
* FlippingHelpless: The brothers can't get past the giant Koopas until [[spoiler:they've learned the fire dash attack]].
* FlunkyBoss: Mom Piranha, who is accompanied by respawning piranha plants.
* {{Foreshadowing}}: "I can't kidnap Peach like this!" "She'll wreck my castle!"
* FrothyMugsOfWater: Played for laughs; what is obviously a wine-making operation instead produces "soda".
* GambitPileUp: And how. Most allied [=NPCs=] were chessmasters at one point or another, with instances including (but not limited to) [[spoiler:swapping Luigi and Peach to have him infiltrate the Koopa Cruiser and completely anticipating Cackletta's fake gift and kidnapping of the princess (and on a sidenote, knowing that the guards would be useless), countering the plan by swapping out her and Birdo, of all things, before the opening cutscene]], and nobody knew what was going on until halfway through the game. Cackletta also manipulated crazy situations, such as making you fix the plumbing to cancel the castle security system. (... In hindsight, that makes even less sense.) By the end, you wouldn't have been surprised if ThePlan set up by the heroes was really just the villains in disguise.
* GenderBender: [[spoiler:''Bowletta'']]. Hoo boy.
* GoldfishPoopGang: The thief Popple and his various partners.
* GottaCatchEmAll: The four Beanbean shards. Notably, Mario and Luigi must find eight fruit to collect one of the shards- making it an example of Catching These Things to Catch All Of These Other Things.
* GlobalCurrencyException: Those 100 coins you got at the beginning of the game turn out to be Mushroom Coins, and are worth 10 Beanbean Coins. (doesn't matter, as you have to surrender it immediately.) And later, when you get an impossibly high amount of coins - something like 9,999,999,999 - it turns out to be Mushroom coins, and is worth... 99 Beanbean Coins. But how could the exchange rate fluctuate so fast? The only logical, foolproof explanation is: The RuleOfFunny.
* GrandTheftMe: Happens to [[spoiler:Bowser when Cackletta's ghost needs to quickly possess a new body in order to survive.]] This causes some PronounTrouble about whether the result is male or female.
* HypnoPendulum: Technically a Hypno Staff, but in any case, Psycho Kamek uses it to [[spoiler:hypnotise Luigi into thinking he's Mario so he's brave enough to go to Guffawha Ruins.]]
* ImplausibleBoardingSkills: How to get across to Joke's End? Easy, Mario can use Luigi as a surfboard simply by hammering him into a convenient slot.
* IntentionalEngrishForFunny: Pretty much everything Fawful says. [[note]]In the original Japanese version, he [[VerbalTic adds "rururururu" to the end of his sentences]].[[/note]]
* IncredibleShrinkingMan: Luigi's second Bros Move, gained near the start of Chucklehuck Woods, allows him to turn Mario tiny by [[{{Slapstick}} hitting him with a hammer.]]
* InstantExpert: Mario and Luigi's Bro moves. Reading the Secret Scrolls once for two moves is apparently enough as well.
* ItemCrafting: The various coffee beans are brought to Professor E. Gadd's coffee shop and blended into stat boosting drinks. He also gives out accessories (and a skit) every time a new type of drink is brewed.
* ItsAllAboutMe: Hermie attacks you because you barged in looking for a MacGuffin and happened to be a world-famous superstar, distracting his friends from fussing over him.
* LaserGuidedAmnesia: Bowser loses his memory and ends up as [[GoldfishPoopGang Popple's dopey sidekick]].
* LightningFireJuxtaposition: Mario and Luigi get Fire and Lightning abilities respectively. This might be due to their personalities. Mario, a hero, is brave and consistent, though his Fire powers existed before this game as the Fire Flower powerup. But Mario is also aggressive and impulsive, showing a little hotheadedness. Luigi, who is slightly lazy and cowardly, (You could say that he's gone in a flash) but is also more expressive in his emotions and funny (he might have a spark of life in him). When Luigi does act, he can make all the difference, and he is as brave as his brother during events with strong enemies. Hence, the partnership between the two.
* LiteralMetaphor: Mario and Luigi have to jump the border from Mushroom to Beanbean early on. To do so, they play a game a jump rope.
* ManHug: Mario and Luigi hug each other at least three times during their adventure; the first time being in Woohoo Hooniversity after Luigi is freed from a barrel mishap, the second time after rescuing Peach from her temporary Teehee Valley kidnapping during the EscortMission (though you can do this again if you let her be kidnapped again) and the third time is when Mario frees Luigi from his tied-up status.
* MetalSlime: Golden Beanies. There's a rare chance of finding one after the brothers defeat a Pestnut (there's usually just a regular Beanie) and they run away the moment their turn comes around, but they drop a relatively large amount of experience and the Spiny Badge, which lets you stomp [[TheSpiny spiked enemies]].
* MutuallyExclusivePowerups: The Piranha Bean will give out either the Piranha Badge or Piranha Suit, depending on whether or not it's fought with a certain item equipped. There's no way to obtain the items anywhere else, so only one of them can be obtained.
* MythologyGag: The plan to disguise Luigi as Peach and turn him over to the villains first appeared in the comic ''ComicBook/SuperMarioAdventures'', which was printed in ''Magazine/NintendoPower'' over a decade earlier.
* NiceJobBreakingItHero: A required task at Beanbean Castle.
* NightmareFuelStationAttendant: Cackletta and [[spoiler:Bowletta]].
* NobodyPoops: Lampshaded when Gadd wants to take a leak. Luigi solves this by vacuuming Gadd into the Poltergust 3000.
--> '''Professor E. Gadd:''' WHERE'S THE RESTROOM?
--> '''Clerk:''' Boss! You never built any toilets in this place!
* NotQuiteDead: [[spoiler:Unfortunately, the Mario Brothers do not realize about Cackletta's soul transfer until it's too late.]]
* OcularGushers: Peach, [[spoiler:who is actually Birdo in disguise]], does this at the beginning of the game, and Luigi does it when telling Mario that [[spoiler:Peach got kidnapped by Bowletta]].
* [[spoiler:OminousFloatingCastle: Bowser's Castle.]]
* OurMonstersAreWeird: This game has the Chuckolator. Which is literally living soda that grows stronger by the power of jokes.
* OutsideTheBoxTactic: The Trunkle boss dies to one or two hits of the Chopper Bros. attack to the forehead. See also AttackItsWeakPoint above.
* PalmtreePanic: Oho Oasis and Gwarhar Lagoon.
* PoorCommunicationKills: [[spoiler:The first few arcs of the plot stem from the fact nobody tells Mario and Luigi what's going on until about a third of the way into the game.]]
* PronounTrouble: Queen Bean uses "he...she...uh, IT" to refer to [[spoiler:the GrandTheftMe character]].
* ItsUpToYou: At one point, Prince Peasley challenges the Mario Bros. to see who can get the most plot coupons, with a large bet hanging on the line. The prince fails to get even a single one, as when trying to get his first one, he gets shrunken down and eaten. In addition, at the beginning of the game, Bowser offers himself and his army to help the Mario Bros, only for them to be shot down. [[spoiler:Ultimately subverted. You never needed to get involved in the first place, due to steps taken prior to the start of the game.]]
* RareCandy: The Bean Coffees. While Woo Beans and Chuckle Beans are plentiful, Hee Beans are only won in minigames, and Hoo Beans are stored in invisible blocks.
* Really700YearsOld: Throughout their adventures in Chateau de Chucklehuck, the Bros. learn of Bubbles, the original founder and owner of the chateau and the rumored creator of Chuckola Reserve, a mysterious soda so shrouded in legend that some doubt its existence. Every indication is given that this character is long dead... [[spoiler:until, of course, Mario and Luigi meet him in the heart of Chucklehuck Woods, where he reveals he's been perfecting his soda for the past ''1000 years''. And what does perfecting soda for a millennium do? ''Grant it life'' and [[EverythingIsTryingToKillYou make it try to kill you]], apparently.]]
* RecurringBoss:
** Popple, as mentioned above, as well as Fawful.
** [[spoiler:Bowser]] as well, even being fought alongside Popple twice.
* RoyalRapier: Used by Prince Peasley.
* [[spoiler:RoyalsWhoActuallyDoSomething: Princess Peach and the Beanbean royalty had Cackletta's initial plan foiled ''before the game even started''.]]
* RumpRoast: [[spoiler:Mario's fire field move involves lighting a fire under Luigi's buttocks to cause him to run as breakneck speed.]]
* SaharanShipwreck: Complete with a SkeletonCrew. They were carrying a shipment of Chuckola Cola, until one sailor drank too much and broke a hole in the ship. [[spoiler:Mario and Luigi inadvertently give the ship its proper burial.]]
* SdrawkcabAlias: Used to hide the word "fatso".
-->'''Skeleton:''' Old Bloat is even more of an "ostaf" than before!... Whuzzat? You dunno what an "ostaf" is??? Seesh! It's simple! Try spellin' it backwards!
* ShieldedCoreBoss: Fawful, the second time you fight him.
* ShoutOut:
** Nintendo even had a few taken out -- the coffee shop was supposed to have a different Nintendo cameo for each new drink, but Professor E. Gadd's role was expanded at the last minute. The accessories he gives out are all references to the characters that would have been giving them out instead. See above entry for DummiedOut.
** The Chuckola Bounce minigame features monsters that spit rocks at you called [[Franchise/TheLegendOfZelda Chuckoroks]].
*** The barrel section in Woohoo Hooniversity is pretty much like a level of [[VideoGame/DonkeyKong]].
*** One of the Hammerhead Bros., after giving Mario and Luigi their hammers, says [[Film/TheWizard "Now you're playing with power!"]]
* SoleEntertainmentOption: A video arcade in Little Fungitown, and a cinema in the middle of nowhere.
* SoloSequence: There are a few situations in which one brother is out of commission, forcing the other to go alone. In addition, there are many puzzles in which the brothers seperate for short times, emphasizing the teamwork in TeamworkPuzzleGame. One dungeon consists of both characters having a solo sequence at the same time. [[spoiler:It's Joke's End.]]
* SpannerInTheWorks: [[spoiler:Half of the game - or hell, maybe the ''whole'' game - wouldn't have happened if Bowser hadn't come to kidnap Princess Peach at the worst possible time.]]
* StealthPun: Joke's End is the place all bad jokes go due to their ''frigid'' reception.[[note]][[DontExplainTheJoke Joke's End is a]] SlippySlideyIceWorld.[[/note]]
* StuckInTheirShadow: Happens InUniverse. Characters recognize Mario, but either forget Luigi, or acknowledge that Luigi is the brother "left behind". This references older games (''VideoGame/SuperMarioRPG'', ''VideoGame/SuperMario64'', the first ''VideoGame/PaperMario'') when Luigi stayed at home while Mario did everything. In ''Superstar Saga'', Mario and Luigi have equally important roles.
* SuddenlyVoiced: [[spoiler:Luigi when he's disguised as Princess Peach.]]
* ThemeNaming: The places around Beanbean Kingdom are named after types of or onomatopoeia for laughter.
* ThrowTheDogABone: Luigi finally gets some recognition (including [[AccidentalMisnaming actually being called by his name]]) when the brothers meet some in-universe fans.
* TrainingBoss: Bowser, as the tutorial. He does one point of damage to you (Mario has 11), and is automatically defeated when he is damaged on the sixth turn. Your only battle command is to attack him and hence damage him, so it's impossible to ''lose'' this fight.
* UnstoppableRage: The brothers first meet Queen Bean after Cackletta forced her to eat a Belly Blech Worm, which turned her into a muscular brute that only focused on violent destruction.
* VerbalTic:
** Popple has the habit of adding "see?" to the end of his lines, see?
** Perhaps you noticed the elderly researcher in Castle Town, and his brother in the Yoshi Theater. Both say "perhaps" often.... Perhaps! (Note: The former uses the word pretty much anywhere in his sentences, whereas the latter always sticks them at the end.)
* VideoGameStealing: Swing Bros. Advance can allow the Bros. to steal the item from an enemy.
* WarmUpBoss: Tolstar, who simply throws spiked balls at our heroes, occasionally trying to fake out our heroes by tossing them above their heads. He eventually starts attacking more when his HP goes down.
* WeaponsGradeVocabulary: Peach's [[spoiler:actually Birdo's]] voice is stolen and replaced with Cackletta's [[StuffBlowingUp explosive vocabulary.]] The characters keep having to scurry out of harms way whenever she speaks. Then she attempts a full paragraph, and blows out every window in the castle.
* [[WhatTheHellHero What The Hell, Bro?]] Hammering Mario or Luigi or setting fire/electrocuting Luigi or Mario before they have learnt the appropriate moves will cause the unlucky bro to yell at his tormentor. Also, in a lesser example, Peach wants to go to Little Fungitown. Luigi thinks it's a bad idea. [[TheAllSolvingHammer Mario whacks Luigi on the head with his hammer]] and says "Let's go!" Problem solved.
* WhoIsThisGuyAgain: Luigi. People often seem to forget/not know his name, and what they do call him usually references the color green.
--> "Mario and... [[BuffySpeak Mr. Green Mario Brother Guy!]]" A guard in front of Beanbean Castle addressed "the famous Mario and Lui-uh... other guy", forgetting the name in mid sentence. In a later scene, the same guard noted, "A very Mario-esque fellow and a Loo...uh, some other guy!"
* WickedWitch: Cackletta.
* WombLevel: [[spoiler:The final boss battle takes place inside Bowser/Bowletta's stomach, though it strangely looks more like a volcano interior than a stomach]].
* TheWorfEffect: At the start of the game, '''Bowser''' gets knocked out in ''one hit'' by Fawful. The same attack takes at least 5 hits to down a bro.
* YouCantThwartStageOne: Actually averted here, due to the heroes being one step ahead. [[spoiler:No, not the Bros. the ''[[RoyalsWhoActuallyDoSomething royalty]]'' The villains fail to obtain both Peach's voice and the Beanstar due to a BatmanGambit by the Princess herself, thus they get pissed and start bombing the Beanbean Kingdom out of rage.]]
* YouHaveResearchedBreathing: Once Luigi learns how to properly shock his brother with the Thunderhand on the field, the bros gain the ability to move in sync with one another as well as the ability to ''walk backwards''. Why Luigi needs to electrocute Mario order for them to accomplish this is a mystery (Luigi's repressed jealously, perhaps?).
