'''''[[PokemonSpeak Yoshi]]!'''''

''Super Mario World 2: Yoshi's Island'', released on the {{SNES}} close to the end of its lifespan, is the first game in a sub-series of the ''Franchise/SuperMarioBros'' franchise, starring Mario's NonHumanSidekick, Yoshi.

The story is set before the original Super Mario Bros. Kamek[[note]]The name all Magikoopas are known by in Japan[[/note]], who is at the time young Bowser's caretaker, looks into the future and sees [[TheGoodGuysAlwaysWin the fate of his young master]]. To prevent this, he blindsides the delivery stork as it's carrying the Bros to their parents but only snags Luigi, dropping Mario over Yoshi's Island and right on the back of one of the dinosaurs. Seeing the map that was bundled with the baby Mario, the Yoshis decided to work together in a relay style fashion to rescue Luigi, all the while dodging Kamek's troops who are searching for Mario.

Gameplay-wise, it shares much in common with its parent series and it even has many of the common Mario enemies. The game introduced Yoshi's egg-throwing ability as well as the GroundPound attack. One difference, however, is that Yoshi doesn't have traditional HitPoints; instead, every time Yoshi is hit, Mario flies off Yoshi's back and a timer counts down. You must retrieve the screaming baby before the countdown reaches zero, otherwise he'll get kidnapped and you'll lose a life. You can increase the amount of seconds on the countdown by collecting stars.

A [[TwoAndAHalfD 2.5D]] {{spiritual successor}} was released on the {{Nintendo 64}} called ''VideoGame/YoshisStory'', which did away with the crying baby and instead focused on Yoshi needing to eat 30 fruit to pass each level, with branching paths, similar to ''VideoGame/StarFox 64''.

The original game was later remade for the GameBoyAdvance, exchanging its ''Super Mario World 2'' label for ''Super Mario Advance 3''. This rerelease was later one of the ten Game Boy Advance games available to participants in the Nintendo3DS Ambassador Program, given a limited rerelease to early adopters of the Nintendo 3DS for free on its eShop in December 2011.

In 2006, ''Yoshi's Island DS'' was released on the NintendoDS, which is much truer to the roots of ''Yoshi's Island'', effectively being its first "true" sequel. This time, you must protect the baby versions of other Mario-verse characters as well as Mario, each baby giving Yoshi new abilities. It starts off deceptively easy, but later descends into NintendoHard.

A new installment to the series, tentatively titled ''VideoGame/YoshisWoollyWorld'', was announced on January 2013. It is similar to works like ''VideoGame/KirbysEpicYarn'' and ''VideoGame/LittleBigPlanet''. [[note]]Not surprisingly, the developer of ''VideoGame/KirbysEpicYarn'' is also behind this game.[[/note]]

In March 2014, a new installment titled ''Yoshi's New Island'' was released for the Nintendo3DS. It follows the same gameplay as the original title, with a few added gimmicks. In this way, it is not dissimilar to the VideoGame/NewSuperMarioBros series. The story, taking place directly after the SNES title, involves the stork delivering Baby Mario and Baby Luigi to Egg Island after it's revealed that they were delivered to the wrong parents. Kamek seizes the opportunity to [[HereWeGoAgain kidnap the babies again, only for Mario to plummet upon the island.]] Here, we find that a new flock of Yoshis has discovered the baby, while Kamek is hot on his trail. Meanwhile, Baby Bowser simply wants to turn Egg Island into his vacation home; thus, the Yoshis make it their mission to thwart Bowser and reunite Mario with his family.

Other ''Yoshi''-themed games include:
* ''Yoshi'' -- PuzzleGame, featuring the grown up Mario and Luigi; one of the early works of [=GameFreak=]
* ''Yoshi's Cookie'' -- A completely different puzzle game, featuring the grown-up Mario, Peach, and Bowser. Developed by Bulletproof Software.
* ''Tetris Attack'' -- Yet another puzzle game, featuring the grown-up Bowser. Of course, it's really just a [[DolledUpInstallment sprite swapped-version]] of the Japanese game, ''Panel de Pon''. Also [[InNameOnly has nothing to do]] with {{Tetris}}[[note]]On the other hand, the Game Boy version was released in Japan with the Yoshi characters as "Yoshi no Panepon".[[/note]].
* ''Yoshi's Touch & Go'': First DS game to bear the title. In a way, this game harkens back to the early days of the original [[NintendoEntertainmentSystem Famicom / NES]], where the main objective is to get the highest score possible.
* ''Yoshi Topsy-Turvy''; known by the name ''Yoshi's Universal Gravitation'' outside the U.S. -- A very short platformer with a tilt gimmick and ''VideoGame/YoshisStory'' style graphics, as well as featuring the grown-up Bowser.
* ''Yoshi's Safari'' -- A light gun game. One of the few games for SNES's Super Scope. This game features the grown-up versions of Mario, "Peach"[[note]]This name specifically; it ended up being the first game to call her "Peach" in North America even though she was officially still called "Princess Toadstool" at the time. She officially became known as "Peach" in North America beginning with ''VideoGame/SuperMario64''.[[/note]], and Bowser.

----
!!The series provides examples of:

* AbsurdlySpaciousSewer: Several levels in ''Yoshi's Story''.
* AdvancingBossOfDoom:
** The final battle against [[FinalBoss Baby Bowser]]. Not exactly an AdvancingWallOfDoom, but once you hit him three times, he [[TurnsRed gets pretty pissed off]] and tries to charge into the foreground. Failing to defeat him in time makes him destroy the terrain, making you fall to your death.
** Sluggy the Unshaven is this- he cannot damage Yoshi in any way, only slowly advancing and pushing Yoshi back. However, the end of the platform leads to a BottomlessPit...
* AndNowForSomeoneCompletelyDifferent: In World 2-1 of ''Yoshi's Island DS'', you are forced to use Baby Donkey Kong to play through the entire level the first time you play it, and you could only use Mario and Peach upon replaying the level. While Baby Peach [[DistressedDamsel had a good reason]], Baby Mario gets no justification for why you can't use him. The same thing was done in both World 3-5 and World 4-5, with Baby Wario and Baby Bowser respectively. Again, no justification exists on why you can't use the other babies the first time around in World 4-5.
* AscendedExtra: The Stork in ''Yoshi's Island DS'' now helps Yoshi out via the Stork Stops.
* AttackItsWeakPoint: {{Lampshade|Hanging}}d in the battle with Sluggy the Unshaven: "Just remember, this slug has no weak points!" Unless you count the big red heart in the center of its body, that is. And guess where you have to aim at to hurt him?
** Lampshaded with Naval Piranha as well. The name is a dead giveaway.
* AttackOfThe50FootWhatever: All of the bosses are enhanced by Kamek's magic in order to make his monsters grow. Inverted with Prince Froggy, though; instead of him being 50 feet tall, ''you're'' 2 inches tall.
* AutobotsRockOut: Final battle theme with Giant Baby Bowser. Blistering electric guitars, anyone?
* {{Autosave}}: The game saves after every level. As does its DS sequel.
* AutoScrollingLevel: Many, and they rank among the most obnoxious levels for both games. "The Very Loooooooong Cave" and "The Cave That Never Ends" are utterly ridiculous with this, having the scrolling screen go in many different directions, crossing the same part of the level more than once in more than one different direction. "Hurry and Throw!" contains a section that scrolls in an endless loop until you figure out how to reach the exit.
** The section of Bowser's Castle just before the final fight in the original game, where Kamek desperately tries to zap you with his magic wand.
* BabiesMakeEverythingBetter: In the sequel, Yoshi ends up carrying babies other than Mario.
* BackForTheFinale: Baby Wario and Baby Bowser return for the final level in ''Yoshi's Island DS''.
* BackgroundBoss: The original ''Yoshi's Island'' ends with this.
* BadlyBatteredBabysitter:
** Except it's not the babies [[EverythingTryingToKillYou delivering the battering]]...
** There's also Kamek. When the first thing your charge does is stomp you flat, there's a reason why he panicks when Baby Bowser wakes up.
* BaitAndSwitchBoss: Upon reaching the boss room in the level "King Bowser's Castle", you'll at first only find Kamek ordering you to "HAND OVER THE BABY!!!", then Baby Bowser wakes up and stomps Kamek flat.
* BigBoosHaunt: Bigger Boo's Fort and Hector the Reflector's Haunted House.
* BlackoutBasement
* BookEnds: World 6 Secret, "Endless World of Yoshis" in the [=GBA=] remake, the last segment of which is... the intro level, "Welcome to Yoshi's Island".
* BossArenaIdiocy: Tap-Tap the Red Nose is invincible to all Yoshi's attacks. Good thing he's just [[spoiler:chilling on a stack of breakable blocks above lava!]]
* BottomlessPit
* BrutalBonusLevel: Pretty much all of the secret and extra levels from both games are this.
* BubblyClouds: "In the Clouds" from ''DS'' and "Welcome to Cloud World" in the original. Probably a few other secret levels too.
* BulletSeed: After eating a watermelon, Yoshi can spit watermelon seeds at enemies to kill them.
* CanonImmigrant: Prior to this game, the Shy Guys' only appearance in the Mario series was as enemies held over from when ''VideoGame/DokiDokiPanic'' was turned into ''VideoGame/SuperMarioBros2''. It was this game that codified them as Mario characters.
* CatSmile: One of the fire enemies. LetsPlay/{{Raocow}} calls them "Catoboos" because of this.
* ChekhovsSkill: Bouncing an egg off the wall. What, you thought the Naval Piranha level just happened to train that to hell?
* ChildrenInTow: The Huffin' Puffins are generally followed by a line of smaller ones. [[VideoGameCrueltyPotential You can bump off the parent and use the children as egg substitutes.]] According to ''Yoshi's Story'', the children don't mind.
* ChuckCunninghamSyndrome: Poochy, who got his own level in ''Yoshi's Island'', appeared as a selectable character in ''[[VideoGame/PanelDePon Tetris Attack]]'', had a minor role sniffing out fruit in a couple levels of Yoshi's Story, and since then has only gotten two cameo appearances in ''VideoGame/MarioKart: Double Dash!!'' and ''VideoGame/MarioParty Advance''.
** TheBusCameBack: Poochy returns for ''Yoshi's New Island''.
* ColorCodedCharacters: Each different-colored Yoshi does the same numbered level in each world (Green starts with the first level, Pink does the second, etc).
** BornUnlucky: The Yellow Yoshi must brave through every fourth level which includes the fortress and mini-boss. The Blue Yoshi has to storm every castle which includes the world's boss (except the last, which is Bowser's Castle for the Green Yoshi).
* ConspicuouslyLightPatch: Each level in the SNES game had 20 red coins, disguised as and placed among regular gold coins. However, if you look very closely, you'll notice that the disguised red coins have a subtle red tint to them, which makes them easy to distinguish from the gold coins once you know what to look for, especially on emulator. This was fixed in the Game Boy Advance remake so they all look the same.
* {{Constellations}}: Upon defeating Raphael the Raven, he flies off into the sky and becomes a constellation.
** An extreme version of ATwinkleInTheSky.
* CosmeticAward: A Perfect Score in an Extra Level adds a Star on the Title Screen.
* CriticalAnnoyance: When you get hit, Baby Mario floats around in a bubble crying until you get him back. You will also hear a beeping noise.
* CrosshairAware: The final boss, and a handful of regular enemies as well.
* CuteButCacophonic: Mario is cute as a baby, but [[CriticalAnnoyance you won't like to hear him cry]].
* DefeatByModesty: Burt the Bashful in the original and the Burt Bros. in ''Yoshi's Island DS''.
* DegradedBoss: Salvo the Slime, a boss from the first game's first world, reappears in a few endgame fortress levels guarding keys as a mini-boss of sorts.
** Though in these cases he's now a bit of a PuzzleBoss, as he no longer drops little Lemon Drop slimes to replenish your egg supply. You have ricochet eggs of the walls and floor to hit him multiple times with a single egg if you don't want to run out before he's dead.
* DeliveryStork
* DemotedToExtra: Poochy - see ChuckCunninghamSyndrome above.
* TheDevTeamThinksOfEverything: See SkippableBoss, where the game takes into account if you use a trick to defeat a boss before the fight technically begins.
* DiscOneNuke: in the original, getting OneHundredPercentCompletion on any given level is quite the feat, considering that, other than five flowers and twenty red coins - both well hidden - the player must also have his or her stars reaching the {{Cap}} of thirty by the end of the level; that said, managing to do so in every level in the first world awards the player with the [[http://www.mariowiki.com/Flip_Cards Flip Cards]]bonus minigame by making it ''accessible at will''. This means that - especially when dissing the whole "avoid Kamek and you get 10 lives" thing - you can use the minigame purely as a source for items, including a whole pack of egg-ammo, the possibility to tell red and yellow coins apart, an "add 20 stars" item... [[GameBreaker you get the picture.]]
* DistressedDamsel: Not Peach, surprisingly, as she's actually a playable character in ''Yoshi's Island DS''. (She does get kidnapped by monkeys in World 2-1, however.) In both games, the damsel is actually Baby Luigi.
* DownTheDrain: "Naval Piranha's Castle" and "The Impossible? Maze" in the original game and "Big Bungee Piranha's Lair" in the DS game.
* TheDragon: Kamek.
* EliteMook: The Zeus Guys. The near invicible bandit sub-species that throw [[KamehameHadoken energy balls]] at you and will punch and kick you if you get too close. They're usually in duos.
* EvilTowerOfOminousness: Nearly every boss level in the series is this.
* EvolvingCredits: If you've last saved in World 6, you get a different title screen. In general, the destroyed castles on the island remain visibly destroyed, replaced by giant "Y" flags.
* EvolvingMusic: For each world you unlock, the map theme gets additional instruments.
* ExcusePlot: ''Yoshi's Island DS'', the story involving [[spoiler:Bowser and the Star Children]] is put into action in the opening, but after that it's only brought up in the second-to-last world and is in a MeanwhileScene that has no real effect on the actual adventure.
* ExtremeOmnivore:
** Yoshi, obviously. He can eat most of the enemies in the game along with watermelons that can give him fire or ice breath.
** Prince Froggy also qualifies because [[spoiler: he eats you, forcing you to boss fight from inside his stomach. Froggy also eats Shy Guys]].
* FakeDifficulty: The invisible clouds in ''Yoshi's New Island'', which half of the game's Red Coins and Smiley Flowers are hidden in, which only appear (very transparently) for a split second at a time.
* FatBastard: The fat Shy Guys that are immune to being stomped due to their bulk. Yoshi can eat them to create huge eggs that act very similar to a POW block.
* FlippingHelpless: This is how you defeat Hookbill the Koopa in ''Yoshi's Island'' and (adult) Bowser's first form in ''Yoshi's Island DS''; Flip them over, then GroundPound their underside to cause damage.
* FutureMeScaresMe / IHatePastMe / OtherMeAnnoysMe: Baby Bowser and adult Bowser in ''Yoshi's Island DS'' do not get along well [[spoiler:until they team up for the final boss fight.]]
* GalacticConqueror: Bowser aims to be this in ''Yoshi's Island DS''. He would later try again in ''VideoGame/SuperMarioGalaxy''.
* GangplankGalleon: World 3 in ''Yoshi's Island DS''.
* GettingCrapPastTheRadar:
** ''Touch Fuzzy, Get Dizzy'' is called '''[[FunWithAcronyms L]]'''[[FunWithAcronyms ustiges]] '''[[FunWithAcronyms S]]'''[[FunWithAcronyms poren]] '''[[FunWithAcronyms D]]'''[[FunWithAcronyms rama]] in the German version.
** In one of the paths in Bowser's Castle, there is a bandit trapped in a small room with burning Shy Guys beneath his feet. Mook punishment?
** A gross way of doing this yourself in the final battle: [[spoiler:just press Y when behind Baby Bowser when you beat his first phase.]] No wonder Bowser grows up to be a CardCarryingVillain.
** After you defeat Prince Froggy, Yoshi squeezes down the bottom of his stomach. When the scene changes to outside, Froggy lays on his back in agony while Yoshi appears between his legs and grows back to normal size.
* GiantSpaceFleaFromNowhere:
** Hector the Reflector and Priscilla the Peckish in ''Yoshi's Island DS'' - enhanced monsters, like most of the other bosses, but monsters ''seen nowhere else in the game''. Similarly, Six-Faced Sal is an enchanted set of ''platforms''.
** Moltz the Very Goonie from ''DS''. Very Goonies (aka the fat goonies that flopped on the ground rather than fly) appeared in a handful of levels in the original game, but Moltz is the ''only'' one in ''DS''. And you don't even see him pre-transformation; he floats down from above the screen once the battle begins.
** [[spoiler:Bowser]] appears this way in Yoshi's New Island.
* TheGoomba:
** Oddly enough, not ''the'' Goomba (which does appear but not until many levels into the game), but rather the Shy Guys from ''[[VideoGame/SuperMarioBros2 Super Mario Bros. 2]]''.
** Also Crayzee Dayzees, which appear later in ''VideoGame/PaperMario''.
* GoombaStomp: Well it ''is'' a Mario series, although here, it won't be your primary means of attack.
* GRatedDrug: Fuzzies.
* GreenHillZone: Much of the first world in all of the games in the series.
* GroundPound: TropeNamer.
* GuestStarPartyMember: In ''DS'', Baby Wario and Baby Bowser are only usable for very specific sets of levels, after which they leave the 'party' until the [[BackForTheFinale final level]].
* HappyEndingOverride / {{Retcon}}: [[spoiler:It turns out that the Mario Bros. were delivered to the wrong house]], leading to the events of ''Yoshi's New Island''.
* HardLevelsEasyBosses: Marching Milde's Fort is long and challenging, but Marching Milde itself is pathetically easy to defeat.
* HeelFaceTurn:
** Baby Bowser in ''Yoshi's Island DS''. And he [[FaceHeelTurn Face Heel Turns]] ''[[HeelFaceRevolvingDoor RIGHT BACK]]'' when you reach the FinalBoss.
** Also some of the bosses and enemies in ''Tetris Attack''.
** Most notably among the bosses turning good would be Raphael the Raven, who also appeared in ''PaperMario'' and helped Mario get access to the volcano.
* HereWeGoAgain: The opening cutscene for ''Yoshi's New Island'' reveals [[spoiler:the stork dropped Mario and Luigi off at the wrong house at the end of ''Yoshi's Island'', and when he rushes to deliver the babies to their proper parents Kamek intercepts him and makes off with Luigi ''again'']].
* HighAltitudeBattle: Rapheal the Raven from the original and Moltz the Very Goonie in ''Yoshi's Island DS''. Former battled on the moon, latter literally battled in [[FreeFallFight free fall]].
* HijackedByGanon: It is implied by his refering to him as his masterful master in the final boss fight against [[spoiler:adult Bowser]] in Yoshi's New Island that [[spoiler:Kamek was given the job of raising Baby Bowser by Bowser's future self.]]
* HumanSnowball: If you hit a rock on a skiing level, you will trip and turn into one.
* ICantBelieveItsNotHeroin: Touch Fuzzy, Get Dizzy.
* IdentityConcealmentDisposal: The epilogue in ''Yoshi's New Island'' reveals that [[spoiler: Mr. Pipe, a warp pipe character that helps Yoshi if he loses too many lives in a incomplete level, is actually Adult Mario in disguise.]]
* ImmediateSequel: ''Yoshi's New Island'' begins right where the original game ends.
* ImplacableMan: Tap-Tap the Golden, encountered in the cave behind Door 3 in Baby Bowser's Castle. He will steadily chase you across the cave and cannot be damaged or defeated by any means; even if he falls into one of the BottomlessPits he will somehow manage to jump back out. Your only option is to knock him backwards with eggs and flee.
* InterchangeableAntimatterKeys : In castle levels, it is apparent.
* InterfaceScrew: Four words: "Touch Fuzzy, Get Dizzy."
** The same thing happens whenever Yoshi will attempt to throw a giant egg.
** There is also the "Grim Leecher", which thankfully is encountered only in a bonus level in ''Yoshi's Island''.
* {{Interquel}}: ''Yoshi's New Island'' directly follows the original games thus is set before ''Yoshi's Island DS''.
* InvasionOfTheBabySnatchers: In ''Yoshi's Island DS'', where there's a worldwide baby-snatching spree.
* JackOfAllStats: Mario (who else?) in ''Yoshi's Island DS''.
* JungleJapes: World 3 in the original Yoshi's Island, and world 2 in Yoshi's Island DS.
* KangarooPouchRide: In the DS version.
* KingMook: Nearly all of the bosses.
* LastEpisodeNewCharacter: Baby Yoshi in TheStinger of ''Yoshi's Island DS''.
* LethalLavaLand: Many levels, but Yikes! Boiling Hot! is the most obvious example of this, as the naming suggests.
* LivingMacGuffin: The seven star children ([[spoiler:Baby Mario, Baby Luigi, Baby Peach, Baby Donkey Kong, Baby Wario, Baby Bowser, and Baby Yoshi]]) in ''Yoshi's Island DS''.
* MakeMyMonsterGrow:
** Just about every boss fight. It's almost a RunningGag for the final Bowser fight in the series now, after a basic fight against Baby Bowser/Bowser, he gets made 20/200 times bigger by Kamek's magic and ends up trying to crush Yoshi and the final castle level flat.
** Inverted one time when Kamek shrinks Yoshi and he gets eaten by the boss.
* ManiacMonkeys: Aw, look at the cute little monkey... wait, did it just steal Baby Mario from me? And why are the other monkeys throwing cactuses and bombs at me?
* MarathonLevel: The Very Looong Cave and The Cave That Never Ends from the original and DS games accordingly, along with A Light in the Dark and Yoshi's Island Easter Eggs from the DS game.
* MarketBasedTitle: Most likely to play on the success of ''VideoGame/SuperMarioWorld'', the original game was named ''Super Mario World 2: Yoshi's Island'' in North America and Europe, despite the fact that it is a prequel. In Japan, it was simply called ''Super Mario: Yoshi's Island''. In all countries, the ''Super Mario World 2'' part is dropped completely from the GBA remakes, in favor of ''Super Mario Advance 3''.
* MeaninglessLives: In the DS game, it is ''very'' easy to rack up over 100 lives in the first half of the game. Subverted in that, in the second half of the game, [[NintendoHard you WILL]] [[PlatformHell need them]].
* MightyGlacier: Baby Donkey Kong and Baby Bowser.
* MinecartMadness: "High Speed Cart Race" in ''Yoshi's Island DS''.
* MiniDungeon: Both ''Yoshi's Island'' games have fortresses at the middle of the worlds, and unlike in the more traditional ''Mario'' games, each of them has a different, unique MiniBoss.
* MonsterCompendium: ''DS'' has a ''museum'' of every enemy defeated with an egg.
* {{Mordor}}: The last level of every game.
* MushroomSamba: The Fuzzies, which cause Yoshi to stumble around as if drunk for a little while, [[InterfaceScrew screwing up his movements.]]
* MusicalNod: The end credits play a slowed-down remix of the ''VideoGame/SuperMarioBros'' Course Clear fanfare.
* {{Nerf}}: In ''Yoshi's Island DS'', red eggs will not bounce off surfaces. Though it nerfs the egg projectile in general, the primary effect is that it makes exploiting the fact that eggs change colour as they bounce to gain red eggs harder than in the original.
** ''DS'' nerfed the entire game in general by ''completely removing the inventory system''. Now, not only can you not make the game easier by refilling your egg supply at the touch of a button or whipping out a melon to spit seeds at enemies, but you are now forced to guard your health bar with your very life, since you can no longer max out your star count at the goal ring simply by using a +10 or +20 star card.
* NeverTrustATrailer: The TV commercial for the original SNES version. It made this game look like a [[GrossoutShow Grossout Game]].
* NintendoHard:
** ''Yoshi's Island DS''.
** As well as Crazy Maze Days/Endless World of Yoshis and Kamek's Revenge in either the original game or the Super Mario Advance 3 remake of the original game.
** Getting all of the [[CosmeticAward totally useless stars on the opening screen]] in the original game and the DS sequel, which involved finding twenty red coins, five flowers, and having a completely full health meter on every level.
* NoNameGiven: Luigi, for some reason. He's just referred to as "Baby Mario's brother" in the original, but is referred to as Baby Luigi for the sequels.
* NonLinearSequel: Yoshi's Island itself to ''VideoGame/SuperMarioWorld'', taking place in the past, yet being named ''Super Mario World '''2''': Yoshi's Island''.
* NostalgiaLevel: Most of World 4, but especially 4-1, consists largely of classic Mario enemies including Goomba, Koopas, Piranha Plants and Wigglers, featured in higher abundance than other levels.
** In the DS game, World 1-1 is a recreation of 1-1 from the original game, 1-4 is a recreation of 1-4 (complete with almost the same boss, except in DualBoss form) while 4-1, "Rock 'N' Fall", is more or less a combination of "Visit Koopa and Para-Koopa" and "Lakitu's Wall" from the original game.
** ''Yoshi's New Island'' has the [[spoiler:[[DiscOneFinalDungeon apparent]] final level, "Baby Bowser's Castle Break-In". Complete with Kamek ambushing, him suffering BaitAndSwitchBoss with Baby Bowser, Kamek then doing to the old MakeMyMonsterGrow to him, them fleeing after his defeat, and the reunion of Yoshi, the babies, and the stork. [[BaitAndSwitchCredits And then adult Bowser ruins the whole thing.]]]]
* ObstacleSkiCourse: Two of the snow levels are this, one is regular, the other bonus. The latter also happens to be the most difficult of the 6 bonus levels... while being the 5th.
* OhCrap:
** Yoshi's expression while he's shrunken by Kamek before Prince Froggy eats him. Oddly enough, he has the same look on his face after he goes through Froggy's other end after the battle, but that's probably because of [[{{Squick}} how he came out]].
** Kamek later gets one in the same world if Yoshi [[spoiler:kills Naval Piranha by firing an egg at her before starting the battle, for a OneHitKill]].
* OneHitKill:
** Lava and Spikes do this to Yoshi.
** The Lunge Fish. Much like his ''VideoGame/SuperMarioBros3'' counterpart Boss Bass, Lunge Fish will try to eat you whole.
** Boss Bass shows up in Yoshi' Island DS alongside Lunge Fish.
* OminousFloatingCastle: Bowser's Castle in Yoshi's Island DS.
* OneWingedAngel: ''All'' of the bosses do this.
* PapaWolf: Yoshi himself. Except for bottomless pits and a few instant-death traps, nothing can actually ''kill'' a Yoshi, and the player can kamikaze through entire ''hordes'' of enemies if necessary to get Baby Mario back before the timer runs out.
* PlatformHell:
** It would not be surprising if Endless World of Yoshis/Crazy Maze Days inspired or was inspired by various ROM hacks and Kaizo type games. And the secret levels in Yoshi's Island DS fit this trope to a T, with the whole point of Yoshi's Island Easter Eggs being ludicrously over the top and somewhat unfair platform challenges.
** Ultimate castle challenge is even worse, with a ridiculously hard obstacle course of one hit kill spikes. However this area can be avoided entirely by stocking up on green watermelons and simply blasting your way through.
* PlotTailoredToTheParty: The DS game is structured so that you have to use all of the babies at some point or another by setting up obstacles which require a particular baby's unique ability to get past.
* PromotedToParent: Yoshi.
* {{Prequel}}: All of the games take place before the main ''Mario'' series.
* RaymanianLimbs: This might not be the case in official art, but in-game? Legs do not exist. There is only disembodied feet.
* RecycledSet: The Advance version recycles sounds originally used in ''YoshisStory''.
* RingOutBoss: Roger the Potted Ghost is probably the UR example, and there's also Big Guy the Stilted in Yoshi's Island DS.
* RiseToTheChallenge: "Welcome to Yoshi Tower!" in the DS game.
* RosesAreRedVioletsAreBlue: In level 3-8, a message box that gives instructions on throwing eggs across water:
-->Roses are red\\
Violets are blue\\
Never forget,\\
What I say to you,\\
Timing is all,\\
And aim true,\\
Measure the angle,\\
And win, do!
* {{Rotoscoping}}: [[http://www.mfgg.net/index.php?act=resdb¶m=02&c=1&id=9916 Bowser's sprites]] in ''Yoshi's Island DS'' [[http://www.mfgg.net/index.php?act=resdb¶m=02&c=1&id=22788 actually come from]] ''Yoshi Topsy-Turvy'', redrawn to fit the graphical style of the former.
* SceneryPorn: The scenery of this game is really, really great, even in a cartoony, hand-drawn way. Especially the underground levels, where you walk on crystals that are ''glimmering''.
* SecretCharacter: White Yoshi and Black Yoshi in ''Yoshi's Story''.
** And indirectly in ''Yoshi's Island DS'', which employs such Yoshis for its secret levels.
* SerialEscalation: The first game has you face Baby Bowser and, after beating him, [[spoiler:an enlarged version of himself.]] In the second game(DS), you first face [[spoiler:Baby Bowser, then adult Bowser and finally an enlarged ''adult'' Bowser.]] In the third game(Yoshi's New Island) [[spoiler:you fight Baby Bowser, then enlarged Baby Bowser, then adult Bowser, ''then'' enlarged Bowser.]]
* SequelDifficultySpike
* SequelReset: ''Yoshi's New Island'' actually starts with the original ''Yoshi's Island'' ending, revealing that the stork actually made a mistake and delivered the Mario Bros. to the wrong couple. So the stork is off to get the babies to the right parents when Kamek returns to capture them again.
* ShoutOut: The final chamber in the final stage of the first game is a long side-scrolling area full of blocks. Kamek randomly appears in the room and tosses out spells that turn the blocks into enemies, identical to how Magikoopas attacked in ''Super Mario World''.
** Burts dress like [[ComicBook/{{Asterix}} Obelix]]. Probably a coincidence, but the French and German translators noticed it and gave them names which are anagrams of "Obelix".
** The snowman enemies are called Dr. Freezegood, most likely a reference to the Music/MotleyCrue song "Dr. Feelgood" (''VideoGame/SuperMarioBros3'' and ''VideoGame/SuperMarioWorld'' already had most of the Koopalings and the Reznor mini-boss bearing music-related names).
* SkippableBoss: [[http://www.youtube.com/watch?v=kdURDeKS5XQ Naval Piranha in the original game]]. If you position yourself on the far left end of the boss room ledge such that Kamek doesn't appear, you can throw an egg at the Piranha Plant to finish it off, skipping the entire fight against it.
-->'''Kamek:''' '''''OH, MY!'''''
* SlippySlideyIceWorld: The first three levels of World 5 in ''Yoshi's Island'', the second half of World 4 in ''Yoshi's Island DS''.
* SpaceZone: Raphael the Raven fought Yoshi on the moon, and ''Yoshi's Island DS'' has space rocket piloting sections.
* SpeciesSurname: All of the bosses have this kind of name.
* SpellMyNameWithAnS: The Japanese version is romanized as ''Yossy Island'' on the box art.
* SpikeBallsOfDoom: The ones in this game are spinning at the end of a spiky contraption. Lakitus can also throw orange variations of them. Later, blue ones can be found on walls.
* SpinoffBabies
* SquashedFlat: There are 3D doors that fall down, and if Yoshi gets caught underneath one of them, he will peel off the door in a paper-like state (which was considered very impressive animation for SNES standards). This is also how Kamek ends up when you face Baby Bowser.
* StalactiteSpite: In some of the levels, there are icicles which await for Yoshi before falling.
* StarsAreSouls: When you defeat [[EnsembleDarkhorse Raphael Raven]], he becomes a constellation.
* [[TheStinger The Stinger]] : Post-credits of Yoshi's New Island reveals that [[spoiler: the pipe that spontaneously grew legs and eyes early in the game was actually a time-traveling adult Mario. In the darkness of the night he shreds his disguise and returns home.]]
* SuddenlyShouting: [[spoiler: One of the different paths in Bowser's Castle starts with a Hint Block that says "RUN AWAY!!! HURRY!!!" When you go down the warp pipe, you are forced to flee from Tap-Tap the Golden. Maybe the Hint Block wasn't kidding.]]
* SuperTitle64Advance: ''Yoshi's Island DS''.
* SynchronizedSwarming: The swarms of bees in the Jungle Hut stage of Yoshi's Story do not like noise and will form a large open palm to stop you if you're moving too loudly. (See VideoGameCrueltyPunishment)
* TakeThat: Harry Hedgehog is a blue hedgehog who runs very fast and tries to ram into you. This is a jab at ''Franchise/SonicTheHedgehog''.
* TeamPet: Poochy.
* ThisLooksLikeAJobForAquaman: Wario's only advantage over the other babies is the magnet he carries. This only comes in handy for obstacles that are specifically designed to make use of it.
* ThrowTheMookAtThem: Various games of the series have bosses that do this, all of which can be eaten to make eggs, which in turn can hurt the boss.
* TimeKeepsOnTicking: The second game's Time Trial mode will let NOTHING stop the clock. And it taunts you for it.
* TimeTravel: Adult Bowser in ''Yoshi's Island DS'' came from the future. It's not explained how Bowser did it, however.
* TrademarkFavoriteFood: Melons.
* TrailersAlwaysSpoil: Magazine/NintendoPower's "[[http://www.youtube.com/watch?v=A-6MURKAmow A Journey Through Yoshi's Island]]" promo video featured a clip of the FinalBoss battle at the very end. It also mentions Baby Luigi during its summarization of the game's story, while the game itself never refers to him by name (in fact, he wasn't actually shown on camera until the very end).
* TravelingPipeBulge: Present in ''Yoshi's Island DS''.
* TrialAndErrorGameplay:
** Pretty much all ''Yoshi's Island DS'' levels, which seem designed to trick you into dying horribly via DeathTraps you have to be psychic to avoid. Especially the skiing in A Light in the Dark and the egg powered platform in Yoshi's Island Easter Eggs.
** Endless World of Yoshis/Crazy Maze Days in the GBA remake of the original. There's a blind free fall past instant kill spikes. Which you then have to do perfectly THREE times. With one checkpoint. There's also a place where you need to hold a flipper open with a Chomp Rock, which is never hinted as even possible in the rest of the game, and is required for 100% completion.
* TurnsRed:
** Happens literally for Raphael the Raven. Each successful hit against him makes him start turning redder and angrier. He becomes faster, and also gains a ShockwaveStomp attack.
** Wiggler/Flutter does this too.
* UndergroundLevel: The Very Loooooong Cave and The Cave That Never Ends, along with many more.
* TheUnfought: In the original and DS Yoshi's Island games, Kamek much prefers mutating enemies into bosses than directly confronting Yoshi. The closest he's come to a boss battle is when he attacks you throughout the final hallway in Bowser's Castle in the first game. Even then, he's more of an obstacle than a real enemy, and can't be defeated (if you attack him, he [[TeleportSpam vanishes and reappears on another part of the screen]]). When you get into the boss room, it looks as though you're finally going into a real battle against him, but he only turns out to be a BaitAndSwitchBoss.
** Averted in the case of ''Yoshi's New Island'', in which Kamek becomes the fortress mini-boss for each world.
* TheUnreveal: [[spoiler: The Mario Bros' true parents finally appear in the epilogue of ''Yoshi's New Island''. Like the couple in the prologue, though, they are silhouetted and their faces aren't shown, making their identities up to our imagination.]]
* UniqueEnemy: Red Bullet Bills that home in on Yoshi appear in the GBA port's Endless World of Yoshis level, though they were technically DummiedOut enemies in the SNES game.
* WarmUpBoss: Burt the Bashful in the first game, and the Big Burt Bros. in the second.
* WhenAllElseFailsGoRight: Subverted at the beginning of both "Hop! Hop! Donut Lifts" and "Shifting Platforms Ahead". Yoshi even turns around automatically if you don't move the moment you gain control of him.
* {{Whammy}}: Kamek, in two of the Bonus Challenge games (Flip Cards and Drawing Lots).
* WombLevel: [[spoiler:The fight against Prince Froggy, where, instead of the boss being giant, Kamek makes you tiny, and Froggy immediately eats you up.]]
** In spite of this, [[spoiler: you will lose a life if swallowed whole by a Lunge Fish in a later level.]]
* VideogameCrueltyPotential: One jungle level in ''Yoshi's Island DS'' is filled with happy, smiling, helpful, delicious monkeys.
* VideoGameCrueltyPunishment: Hitting a swarm of bees with an egg in ''Yoshi's Story'' will get you PUNCHED by them.
* VillainousBreakdown: In the DS version, Baby Bowser throws a tantrum [[spoiler:when he finds out his future self is still a loser trying to take over the world.]]
* YouCantThwartStageOne: Averted. Taking out Naval Piranha before Kamek has a chance to transform doesn't seem so sporting.
