Chain Chomp Wheel is similar to a roulette. You start on a boost pad and get boosted into the roulette. The roulette is spinning, so the item blocks on it are moving. Also in the middle of the roulette is a boost ramp similar to the DS course Tart Top, and you can get an item there. There are also boost ramps along the side, like Funky Stadium, but you can get items on the ramps. And last but not least, the reason it is called Chain Chomp Wheel is because a lose Chain Chomp occasionally rolls around the roulette.
