''New Super Mario Bros. U'' is the fourth game in the ''VideoGame/NewSuperMarioBros'' series and the direct sequel to ''VideoGame/NewSuperMarioBrosWii'', following ''VideoGame/NewSuperMarioBros2''. It features [[VideoGame/SuperMarioWorld Baby Yoshis]] with distinctive abilities, a new power-up called the Super Acorn that gives you a Flying Squirrel suit, and the ability to play the game as your Mii. There is also a "Boost mode" utilized by the WiiU [=GamePad=] that sets up AsymmetricMultiplayer by letting the person with the [=GamePad=] create platforms and assist in multiplayer sessions. Finally, there's Miiverse integration, with various players' comments on levels or deaths coming up when appropriate.

With the return of Baby Yoshis, a powerup similar to the Super Cape, and an interconnecting world map, many [[Franchise/SuperMarioBros Mario]] fans view this game as the closest thing we're going to get to seeing the unique elements of ''VideoGame/SuperMarioWorld'' used in the modern Mario series.

In 2013, Nintendo released ''VideoGame/NewSuperLuigiU'' as part of TheYearOfLuigi, a new adventure featuring 80 new (half-sized and generally more challenging) levels that is offered as both an expansion and a standalone game. As shown by the title, Luigi takes center stage, and Mario isn't a playable character at all. Taking his place will be the rabbit thief Nabbit, who is immune to enemies, and cashes in power-ups for 1-ups instead of using them.
----
!!This game provides examples of:

* AlwaysNight: Frosted Glacier.
* AnIcePerson: The Ice Flower from ''New Super Mario Bros. Wii'' makes a comeback, allowing you to freeze enemies with ice balls. [[spoiler:This is also, once again, the case with the Penguin Suit.]]
* ArtEvolution: The backgrounds are much more variable, with some being literally pieces of art, and the detail on the ground and lighting have been improved a lot. It really helps that the game was made for the WiiU, the first Nintendo console to handle HD graphics.
* AutobotsRockOut: Happens in the final boss battle.
* AutoScrollingLevel: Boost Rush Mode, which seems to be the lovechild of [[VideoGame/NewSuperMarioBros2 Coin Rush]] and Boost Mode. It makes every level you play scroll automatically.
* AsymmetricMultiplayer: There's an option to use the Gamepad to make platforms, amongst other stuff, for the other players who are using Wii Remotes/Gamepad Pros to control Mario and his friends.
* AsteroidsMonster: There are big Goombas that split into smaller ones when stepped upon.
* BalloonBelly: The magenta Baby Yoshis, which when shook, inflate like a balloon, and can be reinflated in the air a few times.
* BoringButPractical: Compared to everyone else, Roy's fight consists of him just pulling out a gun. A ''very big'' gun that shoots Bullet Bills, granted, but it's rather tame compared to summoning clones or defying friction and physics like his siblings do.
* BreakingTheFourthWall: When your player character is idle, they'll stare right at you.
** Just like the previous games, the enemies will dance when the chorus sings (or "bah"s).
*** Plus, Baby Yoshis will hum along to the music when held. However, they don't sing when in a BonusLevelOfHeaven or a Toad house.
* BubbleGun: The blue Baby Yoshis act like this when shook. Enemies caught in the bubbles turn into coins or power-ups.
* TheBusCameBack: After his absence from the [[VideoGame/NewSuperMarioBros2 previous game]], Bowser Jr. is wreaking havoc alongside the Koopalings once again.
* CartoonBomb: Lemmy now tosses these, which are styled after his bouncing balls.
* CeilingCling: Iggy doesn't just do this, he ''flat out walks on the ceiling'' (not unlike [[VideoGame/SuperMarioWorld Morton and Roy]]).
* CerebusSyndrome: A rather mild example, but instead of having Bowser Jr. and/or the Koopalings take the princess to his castle, Bowser instead tosses the Mario Bros. and the two Toads towards Acorn Plains and then begins reshaping Peach's Castle in his image.
* ContinuityNod: [[VideoGame/SuperMarioWorld Slanted pipes, slanted rocks, Munchers, Torpedo Teds, Monty Moles, Baby Yoshis, the style of the overworld, Sumo Bros., Spin Jumping, Flying Squirrel Mario's moves...]]
** [[VideoGame/SuperMario64 This isn't the first time]] [[VideoGame/SuperMarioGalaxy Bowser has taken over Peach's Castle]] [[VideoGame/PaperMario and kept her hostage inside there at the highest point.]] [[VideoGame/MarioAndLuigiBowsersInsideStory This is also not the first time that the castle hasn't been taken over by a villain and]] [[EvilMakeover it being remade in the villain's own image,]] still with the Peach kidnapping.
** So, how about that dark magic Bowser's been said to have that some of the fanbase (and spinoff game titles) like to pretend doesn't exist? In [[VideoGame/SuperMarioBros Mario's first adventure]], Bowser was said to use it to transform the land. Here, we finally see him using it progressively to transform Peach's castle into something he prefers. Well, now we know where he gets all the fire and lava!
** [[VideoGame/SuperMarioGalaxy2 There's also the Magenta Baby Yoshi's abilities, and the Yellow Baby Yoshi's abilities.]]
** Mini Mario can [[VideoGame/SuperMarioWorld run up walls]].
** This game will also be the first since [[VideoGame/SuperMarioBros3 Super Mario Bros. 3]] to have Boom-Boom and the Koopalings in the same game. Boom-Boom and the Koopalings are even the Fortress boss and the Castle bosses, respectively.
*** Unlike in his [[VideoGame/SuperMario3DLand previous appearance]], Boom-Boom fights exactly how he did in his debut. His shell even has spikes again[[note]]Although him pulling out is spikes is accidental this time, as it's now depicted as him falling over.[[/note]], [[spoiler:and he also sprouts wings in his last fight]]. [[VideoGame/SuperMarioBros3 And like before, the Koopalings are fought in airships instead of the castles.]]
** Like VideoGame/SuperMarioWorld, many of the worlds follow EdibleThemeNaming.
** The story intro involves [[VideoGame/NewSuperMarioBrosWii the new power-ups]] [[VideoGame/SuperMario3DLand flying through the air]]. [[VideoGame/SuperMario3DLand And said power-ups come from a giant tree.]]
** [[VideoGame/YoshisIsland Kamek]]'s in, and [[VideoGame/NewSuperMarioBrosWii powers up some bosses]]. [[VideoGame/YoshisIsland He even supersizes a few enemies as well.]]
** The switch at the other side of the bridge with Bowser does not set off said bridge's self-destruct mechanism on it's own accord, but instead [[Videogame/SuperMarioBros sets it off through use of an axe]].
** The level "Boarding the Airship" in Meringue Clouds has a mechanical Bowser hand (The same one that threw the Mario Bros and the two Toads out from Peach's castle) that acts an obstacle for the first part of the level. For the first few parts of it, the hand acts like the giant pillars from VideoGame/SuperMarioWorld (As seen in Iggy's Castle, Forest Fortress, and Bowser's Castle) and later, it destroys the ground in a fist-shape manner exactly like the Incoming Chomps from VideoGame/YoshisIsland.
** [[spoiler: Like in ''Super Mario World'', one of the castles has a secret backdoor.]]
** [[spoiler: Follow that Shell!, the real final level, contains only things found in the first ''Super Mario Bros.'', as well as a P-Switch and Star Coins. Also, the entire Superstar Road looks like Star Road from ''Super Mario World'', and Follow that Shell! is in the middle, much like Special World.]]
** Just like in many previous Mario games, [[spoiler: every Ghost House is guaranteed to have a secret exit.]]
** Soda Jungle 4 and 5, where you are [[spoiler:required to find the secret exit to open the path forward, and the regular exit will just loop back to the same level]]. These levels are found [[VideoGame/SuperMarioWorld inside of a forest]].
** One underwater level has currents over bottomless pits that will suck you in and cost you a life if you get pulled under. ''VideoGame/SuperMarioBros'' had this for its underwater levels as well, though without any visual cues.
* ColorCodedForYourConvenience: Miis have their overalls correspond with what player they are. Player 1 wears Mario's colors, Player 2 wears Luigi's colors, Players 3 and 4 wear [[VideoGame/WarioLand Wario's]] and Waluigi's colors, though they aren't entirely accurate, rather having shades of Mario's color scheme from VideoGame/MarioBros.
** Averted with adult Yoshi. Every one of them is green, regardless of player characters.
** The baby Yoshis are color-coded according to their different powers.
* CoOpMultiplayer: It works exactly like its predecessor. Online is still a no go.
* CutsceneIncompetence: Averted. When Bowser Jr. attacks with the giant claw after his fights, the characters simply get out of the way instead of just standing there.
* DamnYouMuscleMemory: Veterans of the Mario platformers are most likely used to being able to jump through the chains of the ball and chains that swing within dungeons. However, their chains gotten a spiky upgrade in this game so you can't jump through the chains anymore.
* DarkReprise: [[http://www.youtube.com/watch?v=F2JWNgnECVU Peach's Castle itself]] gets one after being [[EvilMakeover transformed]] by the Koopa Troop.
* DemBones: In addition to the ever familiar Dry Bones, we have the return of [[VideoGame/SuperMarioWorld Bony Beetles]].
* DiscOneFinalDungeon: [[spoiler: The first Castle level in World 8 for the main game, Pendulum Castle for Superstar Road.]]
* DoubleJump: One of the features of the Squirrel Suit. [[spoiler:And the Propeller Suit.]]
* DoubleWeapon: Roy's double-ended ''[[ImpossiblyCoolWeapon Bullet Bill Blaster]]''.
* DownloadableContent: Like with the [[VideoGame/NewSuperMarioBros2 previous game]], this installment will receive new levels, made after the game's release. Among these is a pack of 80+ new levels that are harder than the original game's, entitled ''VideoGame/NewSuperLuigiU''.
* DropTheHammer: Morton now uses a hammer in his boss fight.
* DubNameChange: Giant Skewer Tower is named Giant Spike Pillar Tower in PAL regions.
* EasterEgg: [[spoiler:Stand around for about thirty seconds after defeating all the enemies in an Enemy Course, and Nabbit will steal the item from you.]]
** Occasionally, during the title sequence, Luigi will trip instead of doing the simultaneous ground pound.
* EverythingsBetterWithPenguins: [[spoiler:The Penguin Suit returns from ''VideoGame/NewSuperMarioBrosWii'', but you can't get it until you unlock Superstar Road. The Penguin Suit is also used in two of the Challenge Mode levels.]]
* EvilMakeover: Bowser takes over Princess Peach's Castle and gradually turns it into a LethalLavaLand.
* ExcusePlot: A slightly interesting twist on the [[SaveThePrincess Mario series standard]]. Instead of Bowser taking Peach away to his castle, Bowser just throws the Mario Bros. ([[MyFriendsAndZoidberg and Yellow and Blue Toad]]) halfway across the world, forcing them to travel all the way ''back'' to Peach's Castle. Meanwhile, with the heroes gone, Bowser takes over Peach's Castle, and subsequently, the Mushroom Kingdom.
* FaceShip: The Koopalings now have their own personalized airships, all with their faces on the helm. This is also the case for Bowser's airship as well.
* FakeLongevity: At least, if you're trying to get all the Star Coins. Some of them require a specific powerup, while others require that a level be played twice (in one case of the latter, you even have to enter one level from another direction to eventually all three of them).
* FinalBoss: [[spoiler:Well of course it's Bowser again, but what makes it different is that unlike the [[{{VideoGame/NewSuperMarioBros}} last]] [[{{VideoGame/NewSuperMarioBrosWii}} three]] [[{{VideoGame/NewSuperMarioBros2}} games]] where you had to avoid him when he was [[MakeMyMonsterGrow supersized]], this time you actually fight him ''while'' he's supersized]].
* FisherKing: When Bowser takes over Peach's Castle, the surrounding area turns into the usual LethalLavaLand associated with him.
* FragileSpeedster: Mini Mario, [[VideoGame/NewSuperMarioBros as]] [[VideoGame/NewSuperMarioBrosWii per]] [[VideoGame/NewSuperMarioBros2 usual]], but this time, Mini Mario has the ability to run up and down any vertical surface, even ''water geysers''.
* GameplayAndStorySegregation: After you complete the game, Peach's Castle will ''look'' like it's back to normal. However, getting there changes it back to when it was in the tornado.
* HatOfFlight: [[spoiler:The Propeller Suit once again. You can only get it in Superstar Road though, but it is also used in one of the Challenge Mode levels.]]
* InterfaceSpoiler: Unlike ''New Super Mario Bros. Wii'', the Star Coin list in this game spoils the secret levels. (If you've got all the Star Coins in every available level in a world, but don't see the "You've got all the Star Coins in World X!" message, you know you're missing a secret exit.) And Miiverse posters don't help either.
* KaizoTrap: No, really. There is one. [[spoiler: Pendulum Castle, the Disc One Final Dungeon of Superstar Road, ends with the classic Mario-style staircase to the flagpole... made out of Donut Lifts. They appeared throughout the level so you wouldn't stand in one place for too long. They didn't say you couldn't walk through them and fall right down to your death, meaning that if you're trying to repeatedly jump to gain speed, you'll probably jump right through them.]]
* KingMook: The boss of Screwtop Tower is a Kamek-empowered Sumo Bro.
* LightEmUp: [[VideoGame/SuperMarioGalaxy2 Like its adult counterpart]], the Yellow Baby Yoshis light up dark rooms.
* MercyMode: The Super Guide from ''VideoGame/NewSuperMarioBrosWii'' is back, but this time it appears when you lose in a level only five times instead of eight.
* MusicalNod: The music for the initial encounter with Bowser bears a similarity to the final boss theme from ''VideoGame/SuperMarioBros3''.
** The Baby Yoshis singing when held is a reference to the title screen of TetrisAttack, where they also sing.
* NotQuiteFlight: [[http://www.mariowiki.com/images/thumb/a/a3/WiiU_NewMarioU_3_char02_E3.png/480px-WiiU_NewMarioU_3_char02_E3.png The Flying Squirrel power up]] acts like [[VideoGame/SuperMarioWorld the Cape Powerup]], can get an extra boost in height if you shake your controller, and it can also cling to walls. [[spoiler:Additionally, the Propeller Suit from ''NSMB Wii'' can be found in the bonus world, and it has the same non-flight as before.]]
** The P-Acorn, however, averts this, as you can fly indefinitely with it.
* PokemonSpeak: If you meet a Baby Yoshi in the World Map for the first time, its text box will say, "Yoshi!" followed by what it's actually saying in parentheses.
* PowerUpMount: Yoshi is ride-able once again.
* PunctuatedForEmphasis: The challenge ''Don't. Touch. Anything.''
* PunnyName: ''Nabbit''.
* RandomEncounter: Bowser Jr., in his father's airship, will ambush you on the world map.
* RecurringRiff: Like in VideoGame/SuperMarioWorld, this applies to the title screen, main menu, overworld, athletic, and snow themes. The other level themes, however, do not have this treatment, though Baby Yoshis add choruses to the recycled music as well.
** The world map themes also do this, with each of them being a specific remix of Acorn Plains' music (for example, Sparkling Waters has a tropical remix, and Frosted Glacier has a Christmas remix).
* RecycledSoundtrack: All of the level themes, with the exception of the overworld, athletic, snow, and final level themes, have been recycled from VideoGame/NewSuperMarioBrosWii.
* RedBoxingGloves: [[http://www.mariowiki.com/File:Bowserjr_NSMBU.png Bowser Jr.'s Koopa Clown Car now sports them.]]
* RidiculouslyCuteCritter: The Waddlewings. [[http://oyster.ignimgs.com/mediawiki/apis.ign.com/new-super-mario-bros-u/3/3a/FlyingSquirrel0NSMBU.png Just look at them!]]
* SaveThePrincess: In a twist similar to ''VideoGame/SuperMario64'' and ''VideoGame/PaperMario'', Princess Peach is apparently held as a prisoner within her own castle again. Only this time, Bowser took over by literally throwing the Mario Bros. and two Toads all the way out of the Mushroom Kingdom.
* SceneryPorn: [[http://www.mariowiki.com/images/thumb/0/09/WiiU_NewMarioU_1_scrn01_E3.png/640px-WiiU_NewMarioU_1_scrn01_E3.png You have to be crazy]] [[http://www.mariowiki.com/images/thumb/4/49/WiiU_NewMarioU_3_scrn10_E3.png/640px-WiiU_NewMarioU_3_scrn10_E3.png to say it doesn't]] [[http://www.mariowiki.com/images/thumb/6/64/Ghost_Painting_MarioWiiU.png/640px-Ghost_Painting_MarioWiiU.png look better than]] VideoGame/NewSuperMarioBrosWii.
* SecretLevel: Much less frequent than in previous games. While those tended to have secret goals (some leading to secret levels, others just being shortcuts) everywhere, here each world generally has just one or two secret goals hidden in it, leading to one hidden level, and completing ''that'' often lets you skip entire worlds (a shortcut from Acorn Plains-2 leads all the way to Soda Jungle, skipping ''four worlds''). To make up for that, the hidden goals are also much more difficult to find this time around and the hidden level spots don't appear until they're actually unlocked.
* SequelDifficultySpike: People expecting the game to be as easy as its [[{{VideoGame/NewSuperMarioBrosWii}} predecessor]] are in for a rude awakening; the game is ''much'' less forgiving after the first world, and it only gets harder from there. Granted you can still hoard lives and [[GameBreaker P-Acorns]] to combat this, but doing the platforming and puzzles the way they were intended will test your skills and patience, especially some of the Star Coin placements.
* ShoutOut: [[BigBoosHaunt Painted Swampland and Spinning Platforms of Doom]] are inspired by Creator/VincentVanGogh's Starry Night. May also count as a CallBack, since a similar background showed up in ''VideoGame/YoshisIsland''.
** The Flying Squirrel suit turns Mario's clothes the same color they were in ''VideoGame/SuperMarioBros''.
** Soda Jungle-2's alternate name, [[Music/SimonAndGarfunkel Bridge over Poisoned Waters]].
** An [[http://www.mariowiki.com/Piranha_Plants_on_Ice icy level]] in the desert-themed second world? [[VideoGame/SpyroTheDragon1998 Where have we seen that one before?]][[note]](The referenced Spyro level in question is Ice Cavern, seen in the second world - the Peace Keepers' desert. Bonus points for both stages being set during nighttime.)[[/note]]
* StunGun: The yellow Baby Yoshi's secondary ability.
* SuperTitle64Advance
* TeleFrag: Kamek can do this to you in his boss fight if you're not careful. At least they have the decency of pointing out where he's going to appear next with sparkles, but if you don't realise in time...
* ThiefBag: [[http://www.mariowiki.com/images/thumb/5/59/MushroombanditNSMBU.png/480px-MushroombanditNSMBU.png Nabbit's bag, which has a P-Acorn inside.]]
* TitleTropes
** AlliterativeTitle: ''Tilted Tunnel'' (Acorn Plains-2), ''Spike's Spouting Sands'' (Layer-Cake Desert-4), ''Seesaw Shrooms'' (Meringue Clouds-2)
** DoomyDoomsOfDoom: ''Spinning Platforms of Doom'' (Superstar Road-5)
** EdibleThemeNaming: All of the worlds [[spoiler:sans Superstar Road]]. Peach's Castle seems like less of an actual example, at least until you remember that Princess Peach herself is named after a fruit.
*** ''Acorn'' Plains is named after the acorn, ''Layer-Cake'' Desert is named after the type of cake, ''Sparkling Waters'' is named after a type of carbonated water, ''Frosted'' Glacier could be a reference to frosting, ''Soda'' Jungle is named after, well, soda, ''Rock-Candy'' Mines is named after the type of candy, and ''Meringue'' Clouds is named after the French dessert.
** ExcitedEpisodeTitle: ''Walking Piranha Plants!'' (Rock-Candy Mines-5), ''Swim for Your Life!'' (Superstar Road-3), ''Follow That Shell!'' (Superstar Road-9), and most notably, ''Lakitu! Lakitu! Lakitu!'' (Superstar Road-7)
* UnexpectedCharacter: The boss of Screwtop Tower, Boss Sumo Bro., who doesn't even appear on the top of his tower on the world map (he briefly appears there after his defeat, however).
* VariableMix: Like with [[Videogame/SuperMarioWorld other games]] [[Videogame/NewSuperMarioBrosWii with]] [[VideoGame/SuperMarioGalaxy2 Yoshis]] in them, the music changes in a way when you grab a Baby Yoshi. They add a sort of choir part to the current music.
** ShoutOut: The Baby Yoshi choir is a reference to the singing Baby Yoshis on the title screen for ''[[VideoGame/PanelDePon Tetris Attack]]''. Interestingly, the Baby Yoshis in Tetris Attack were also blue, magenta, and yellow.
* TheVeryDefinitelyFinalDungeon: [[spoiler: The Final Battle, the true castle level for the final world. Pendulum Castle seems this way, but it is only the ''penultimate'' level.]]
* VideoGameSettings:
** Acorn Plains: GreenHillZone
** Layer-Cake Desert: ShiftingSandLand and LevelAte
** Sparkling Waters: PalmtreePanic
** Frosted Glacier: SlippySlideyIceWorld
** Soda Jungle: JungleJapes and BigBoosHaunt
** Rock-Candy Mines: DeathMountain
** Meringue Clouds: BubblyClouds
** Peach's Castle: LethalLavaLand and {{Egopolis}}
** Superstar Road: BonusDungeon
* VideoGameCaringPotential: Players on a [=GamePad=] can spawn blocks in midair to help players over bottomless pits...
* VideoGameCrueltyPotential: ...or can use the blocks to obstruct players while they jump, knocking them into enemies or pits.
** [[spoiler:In the final boss battle, you have to hit Bowser Jr. to take control of his Koopa Clown Car. Besides Bowser's attacks and the fact that Bowser Jr. could retreat into his shell, there's nothing stopping you from repeatedly stomping him before he gets back in his Clown Car... You can even hurt him WITH the Clown Car.]]
* XMeetsY: VideoGame/NewSuperMarioBros meets VideoGame/SuperMarioWorld, with a dash of VideoGame/SuperMarioBros3.
