The racing engine is quite nice. The cars feel great, and some tracks even go across water, where the cars turn into boats. Players can upgrade the existing car, or buy higher-level cars with money, which is earned in races and picked up while adventuring. Tracks have special turbo powerups and other hidden surprises (like big jumps and other exciting additions).

There's a lot more to do than race, however. The adventure mode has players wandering around different areas of the world, gathering railroad coins, money and nuts (which can be traded to Chip and Dale for information and special items). Players can also visit Magica de Spell to get magic spells to use during races (like Mickey's Sticky Net, which slows other racers down, or Donald's Duck Bomb).

Even Pluto, Mickey's trusty dog, has his own Dig-Dug-esque minigame. At certain places, an exclamation point appears over the dog's head, and he can then dig a hole that leads him to the game. The game is quite simple, usually -- collect bones or kill the enemies, but can also be quite difficult -- frustrating, to be exact. Each of the race worlds contains four Bone Hunts, and Pluto has to finish them all to get a Golden Bone -- six of which are required to meet Pete in the final race.

All in all, the racing is excellent and the adventure elements lend some variety to the game. Much of the game can become frustrating, however -- it takes a while to get from one character to the next, and Pluto's Bone Hunt games are particularly hard. But once the racing starts, the game shines forth as a blazing example of how to do a fun cart game on the Game Boy Color.
