''[=ChuChu=] Rocket'' is a multiplayer video game by Creator/SonicTeam for the UsefulNotes/SEGADreamcast, later adapted for the UsefulNotes/GameBoyAdvance and for iOS devices. The object of the game is to (for the most part) put little space-[[MickeyMouse mickey-mice]] thinggies into four different-colored rockets to get them away from [=KapuKapus=], i.e., cats. Basically it's a game of cat-and-mouse, [[RecycledInSpace IN SPACE!]]

According to the ExcusePlot, there are four individual pilots for the rockets:
* Chuih, a [=ChuChu=] with a blue astronaut suit and stars in his eyes, pilots the blue rocket.
* Chubei, an abnormally large [=ChuChu=] with a yellow spacesuit, pilots the yellow rocket.
* Chubach, a thin, green [=ChuChu=] with swirly eyes ([[OpaqueNerdGlasses apparently glasses]]), pilots the green rocket.
* Chupea, a red female [=ChuChu=] with a heart-shaped tail, pilots the red rocket.

The game employs arrows on a giant checkerboard that are to lead the [=ChuChus=] to the rockets. You get three arrows—no more, sometimes fewer. Occasionally the [=KapuKapus=] will show up and use the same arrows you placed to follow the [=ChuChus=] and eat them (this is actually the point of one of the mini-games). It gets much harder when you realize that the [=ChuChus=] go so [[GoshDangItToHeck dang]] fast that it's almost impossible to even '''see the dang things moving around'''. And that's assuming you're playing by yourself—it gets a lot more complicated when you use multiplayer (arguably the whole point of the game's existence) and there are four sets of three arrows littered over the board, which could potentially lead a [=KapuKapu=] to eat your [=ChuChus=].

!! Tropes associated with ''[=ChuChu=] Rocket'' include:

* AllThereInTheManual: The [=ChuChu=] Pilots don't actually appear in the game, but their rockets do—the only way you know of their existence (other than [[VideoGame/SegaSuperstars that one game]]) is through the manual.
* ArtificialStupidity : Even though they're [[TheComputerIsACheatingBastard faster than humans]], the {{AI}}s in the UsefulNotes/GameBoyAdvance port sometimes place arrows incorrectly. For example, if the goals are close together, it may place arrows to direct cats or mice to the wrong rocket.
* AscendedExtra: The Chuchu Pilots Chuih, Chubei, Chupea and Chubach are seen only in the manual, but appear later in ''[[VideoGame/SegaSuperstars Sonic & SEGA All Stars Racing]]''.
* BagOfHolding: Inverted with the rockets, to some degree. Played straight with the holes the [=ChuChus=] come out of.
* CatsAreMean: And orange.
* EscortMission
* ExcusePlot: The 'plot' of this game is to play as four unseen [=ChuChu=] Pilots to get away from giant mutated cats. You soon forget this.
* GameLobby: The game had this feature. Matches were pretty quick in that game.
* Instant180DegreeTurn: Normally, if you hit a wall, you turn right (or left if no right turn is possible), but if you reach a dead end, you make a 180. You can also force an instant turn using arrows. Mouse happily turn around, but the arrows only work twice on cats for a 180.
* LawOfOneHundred: Some challenge levels require you to rescue 100 mice (or [[InstantWinCondition let you win]] if you lead the CPU player by that many). Coincidently, there's a maximum of 100 mice allowed on the playing field at once.
* [[OneBulletAtATime Three Arrows At A Time]]: Challenge or versus modes.
* ProgrammingGame: In Puzzle Mode, the only effect you have on the game is to place the arrows at the beginning of each level. Once you tell it to start, you can only watch what happens.
* RiddleForTheAges: Where do the [=ChuChus=] GO in their rockets anyway?
* ShoutOut: A few puzzles reference SonicTheHedgehog.
* TimedMission: Each stage challenge needs to be completed in 30 seconds.
* AWinnerIsYou: At least in the UsefulNotes/GameBoyAdvance version, beating all 2600 puzzles will make a message from Sega appear after the credits, telling the player to send a letter to them in order to get a gift. ItOnlyWorksOnce, and is probably worth nothing nowadays.
