Released exclusively for the Creator/{{Sega}} UsefulNotes/GameGear in 1994, ''Sonic Triple Trouble'' or ''Sonic & Tails 2'' as it is known in Japan  is the sequel to ''[[VideoGame/SonicTheHedgehogChaos Sonic Chaos]]'', and is widely considered one of the best ''[[Franchise/SonicTheHedgehog Sonic]]'' games to appear on the handheld, mostly due to it being the closest in feel to its 16-Bit brothers on the UsefulNotes/SegaGenesis. It features the debut of Fang the Sniper (or Nack the Weasel, as he was initially known in English versions).

Somehow finally collecting the six Chaos Emeralds without catching the attention of Sonic, [[BigBad Dr. Ivo "Eggman" Robotnik]] was testing his latest weaponry when suddenly an accident scattered them once more. Robotnik was able to find one of them, but of course, Sonic and Tails learned about what happened, and now they're off to find the other five before Robotnik can. Expecting this would happen, Robotnik once again deceives Knuckles the Echidna into believing that Sonic and Tails are trying to steal the Emeralds. Thus, Knuckles becomes a nuisance that tries to inhibit the duo's progress. As all of this is happening, Fang the Sniper, a treasure-hunting weasel, has successfully located the other five during the commotion. Are you up to the challenge of thwarting this [[TitleDrop Triple Trouble]]?

In addition to the Pogo Spring and Rocket Shoes from ''Sonic Chaos'', ''Triple Trouble'' also gives both playable characters (Sonic and Tails) their own special modes of travel. In Robotnik Winter Zone, Sonic can shred on a snowboard (far more flexible than in [=IceCap=] Zone in ''[[VideoGame/Sonic3AndKnuckles Sonic the Hedgehog 3]]''), and in Tidal Plant Zone, he can equip himself with scuba jets, which actually allow the blue hedgehog, well known for his {{super drowning skills}}, to ''[[SuperNotDrowningSkills swim]]'', though for a limited time. Meanwhile, Tails in Tidal Plant Zone can pilot the Sea Fox submarine, which comes equipped with a torpedo launcher and easy up-and-down movement while underwater. Tails would use the Sea Fox again in ''VideoGame/TailsAdventure''.

Amusingly, on the American and European boxarts, Robotnik is depicted in a slightly modified version of his ''WesternAnimation/AdventuresOfSonicTheHedgehog'' incarnation (this also happened on the North American boxart for the Game Gear port of ''VideoGame/SonicSpinball'', even though the Genesis original used the Classic Eggman; one of many reasons no one mentions the Game Gear version).
----
!! This game provides examples of:
* AWinnerIsYou: Your reward for getting the five Chaos Emeralds (the sixth one is automatically given after defeating Robotnik) is to see the ending credits with Sonic and Tails flying over the ocean, and the game thanking you for playing. The End.
* AesopAmnesia: Knuckles somehow got tricked by Eggman that Sonic is up to no good ''again'', and not only constantly impedes Sonic's progress, but even fights him in a robot in Tidal Plant. Electrocuting him in the Hidden Palace must have fried a few brain cells...
* BaitAndSwitchBoss: After you defeat Metal Sonic in Atomic Destroyer Act 3, a sleeping Nack the Weasel awakens and it seems like you're going to fight him one last time, but then he panics and runs away from the true final boss, Dr. Robotnik.
* BossCorridor: Each boss encounter has some sort of straight corridor prior to it.
* BossOnlyLevel: In keeping with the Game Gear tradition, the third act of each Zone is a very short or very straight running/platforming segment or just a BossCorridor and then a boss fight; like ''Sonic Chaos'', there are rings available for Sonic. The last level actually has Metal Sonic as a sub-boss between two platforming hallways, with the second hallway leading to Robotnik/Eggman.
* BottomlessPit: As usual, the game has these everywhere except the first Zone. The pits in the final Special Stage will kick you out of the stage if you fall into them, and said stage is a bit of a puzzle.
** Act 3 of Sunset Park has Sonic running on a train, and there are two or three gaps between cars early on that count as bottomless pits if he falls into them.
** Meta Junglira has mud. Fall too far into the mud, you fall off the screen.
** And a handful of ice pits in Robotnik Winter have nothing below them, although some emit gusts of wind to take you up.
** After defeating Robotnik/Eggman at the end of the game, Sonic/Tails smash his getaway platform and send him plummeting into a pit.
* ClassicCheatCode: A very easy one to put in exists in the game; hold up on the D-pad as the game boots up and don't let go, and in the opening cutscene, press start at the ''exact'' moment Knuckles grabs the third Chaos Emerald (and we mean your timing has to be nearly ''frame perfect''--if you're even slightly off, it won't work). If you do it right, you'll hear a subtle chime sound effect, and after you select Sonic or Tails, a level select screen will pop up.
* ComicBookAdaptation: A 48-page special by Franchise/ArchieComics.
* CombatPragmatist: Nack the Weasel is willing to fight dirty to beat Sonic. His first boss fight has him attempting to activate a flame trap (which backfires on him). In his fourth fight, he fires a heat-seeking missile at you (which also backfires on him).
* CoolPlane: The Tornado, which appears in the even-numbered, non-platformer the Special Stages.
* DimensionalTraveler: Nack the Weasel is actually from the same dimension that the games [[BonusStage Special Stages]] are set in.
* DistressedDude: [[spoiler:After battling Eggman in Atomic Destroyer Zone, Knuckles is shown held in a small prison capsule (presumably since he failed to defeat the player back in Tidal Plant Zone), which Sonic/Tails then destroys, letting him free.]]
* EvilOverlooker: Robotnik in the North American and European box art.
* HarmlessVillain: Nack the Weasel. He serves as the boss of the Special Stages, but all of them are ridiculously easy. In the first boss fight, he presses a button to set a flame trap on you but then accidentally unleashes it on himself. In Atomic Destroyer, he reappears again prepared to fight you...[[ScrewThisImOuttaHere and then promptly runs away in terror]] when Eggman approaches.
* HoppingMachine: The first Nack the Weasel contraption that the player actually does have to dismantle; it shouldn't be hard. Also, the first phase of the final boss involves Robotnik in a spring pod of his own.
* InCaseOfBossFightBreakGlass: The first part of the boss fight with Robotnik/Eggman at the end of the game requires you to jump on top of his spring pod enough to chase him out of the room.
* LoadBearingBoss: Once Sonic destroys the caterpillar boss in Meta Junglira, he must then dodge the robot's falling body parts for the rest of the fight.
* OffModel: For some reason, the overseas boxart uses the ''WesternAnimation/AdventuresOfSonicTheHedgehog'' design for Robotnik, even though that design is not used in the game.
* OnlyInItForTheMoney: Nack the Weasel. He's a treasure hunter who wants the Chaos Emeralds not for their power, but because they would fetch him a hefty profit.
* SequentialBoss: As per tradition, the final level of the game has 5 separate boss phases: First Metal Sonic, then after a short platforming segment and a checkpoint, 4 machines piloted by Robotnik/Eggman (a spring pod machine, a flamethrower machine, an electric machine, and then a laser trap room with the boss pod circling through pipes on both sides of the room).
* SoundTest: Unlike in ''Chaos'', the Sound Test in ''Triple Trouble'' does not require a cheat code to access it. Just press Up/Down until it appears.
* SuperNotDrowningSkills: In Tidal Plant Act 3, Sonic and Tails are in no danger of drowning until they fight Knuckles, and even then, air bubbles pop up occasionally in the fight so they don't drown.
* TacticalSuicideBoss[=/=]HoistByHisOwnPetard: Happens to Nack in the last two Special Stage boss fights; the first one has him fire a giant missile that flies back and forth and eventually right into him if you last long enough. The last one has Nack in a drilling machine, and one of his drilling attempts gets him stuck in the floor; all Sonic/Tails have to do is pound him into the ground.
** This also happens with the first level boss of the game; after delivering four hits to the turtle robot, it summons turtle spring robots, which Sonic and Tails then need to use to reach him for the second four hits to finish him off.
** This also happens in the battle against Metal Sonic. If Metal had simply did his charge attack which makes him invincible throughout the battle instead of swooping down at the player, he would be impossible to defeat.
* TerribleTrio: Eggman, Knuckles (by virtue of his gullibility), and Fang, hence the English market title.
* TraintopBattle: Since Sunset Park Zone Act 3 takes place on a train, the boss is the engine itself, which fires spiked cannonballs at the player.
* TurtlePower: The first boss of the game is a metallic flying turtle.
* UnderwaterBossBattle: Surprisingly, the first part of the first boss has you underwater, jumping out to hit a turtle robot. Tidal Plant Zone's boss much later in the game (Knuckles in a submersible with torpedoes and depth charges in a scrolling room) is entirely underwater.
* VideogameSettings:
** GreenHillZone / PalmtreePanic: Great Turquoise Zone
** AmusementParkOfDoom: Sunset Park Zone
** EternalEngine: Sunset Park Zone, Tidal Plant Zone and Atomic Destroyer Zone
** LocomotiveLevel: Sunset Park Zone's third act
** AutoScrollingLevel: Sunset Park Zone's third act and Tidal Plant Zone's third act when the boss fight with Knuckles in his submersible begins.
** JungleJapes: Meta Junglira Zone
** SlippySlideyIceWorld: Robotnik Winter Zone
** PipeMaze / UnderwaterBase: Tidal Plant Zone
** BossOnlyLevel: Tidal Plant Zone's third act; while the third acts of all the zones are small boss stages, this one's the smallest and after a few rings goes into the Knuckles boss fight.
** CyberSpace / TheVeryDefinitelyFinalDungeon: Atomic Destroyer Zone
** BonusStage: The Special Stages
*** TempleOfDoom: Special Stages 1, 3 and 5, and all Nack/Fang battle zones.
*** LevelsTakeFlight: Special Stages 2 and 4
* WarmUpBoss: The first boss, a flying turtle, is actually incapable of directly harming you--the only way it can is for you to get knocked into it by a spring moto-bug while being out of your ball form.
* VillainExitStageLeft: For no clear reason, Nack the Weasel shows up one more time in Atomic Destroyer Act 3 to confront Sonic, but when Robotnik shows up in his latest machine, Nack hightails it out of there. If you didn't collect the five Chaos Emeralds, the ending cutscene shows Nack laughing and escaping, but he trips up and drops the Chaos Emeralds the player didn't collect, prompting the game to tell you to Try Again.
* YouHaveOutlivedYourUsefulness: A possible reason for [[spoiler:Eggman imprisoning Knuckles in Atomic Destroyer Zone's third Act.]]
* ZeroEffortBoss: Some of the boss encounters with Fang in the Special Stages. In the first Special Stage, he hits a switch and fries himself.
