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:
* AmusementParkOfDoom: Sunset Park Zone.
* 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.
* ComicBookAdaptation: A 48-page special by ArchieComics.
* CoolPlane: The Tornado, which appears in some of the Special Stages.
* DistressedDude: [[spoiler:After battling Eggman in Atomic Destroyer Zone, Knuckles is shown held in a small prison capsule (presumably since he failed to defeat Sonic in the previous Zone), which Sonic then destroys, letting him free.]]
* DownTheDrain: Tidal Plant Zone.
* EternalEngine: Atomic Destroyer Zone.
* EvilOverlooker: Robotnik in the North American and European box art.
* GreenHillZone: Great Turquoise Zone.
* HoppingMachine: The first Nack the Weasel contraption that the player actually does have to dismantle; it shouldn't be hard.
* 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.
* JungleJapes: Meta Junglira Zone.
* 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.
* 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).
* SlippySlideyIceWorld: Robotnik Winter Zone.
* SoundTest: Unlike in ''Chaos'', the Sound Test in ''Triple Trouble'' does not require a cheat code to access it.
* 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.
* TerribleTrio: Eggman, Knuckles (by virtue of his gullibility), and Fang, hence the English market title.
* TurtlePower: The first boss of the game is a metallic flying turtle.
* UnderwaterBase: Tidal Plant Zone seems pretty industrial. It's effectively Labyrinth Zone but [[UpToEleven with even more water]] and more machines.
* 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 [[spoiler:Knuckles in a submersible with torpedoes and depth charges in a scrolling room)]] is entirely underwater.
* 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.
* YouHaveOutlivedYourUsefulness: [[spoiler:A possible reason for 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 quite literally hits a switch and fries himself.
