Chain Chomp

The Chain Chomp is an enemy in Bob-omb Battlefield. It is a large black ball with a mouth and eyes, attached to a pole. It will charge at Mario when he draws near. If you ground pound the pole in the mission Behind Chain Chomp's Gate, it will jump around, destroying the gate blocking the star next to it, and jump away.

Small Chain Chomp
Allegedly an enemy found in certain personalized copies of the game. It takes the appearance of the Chain Chomp seen in Bob-omb Battlefield, only much smaller (around the size of a Chuck-ya) and attached to a smaller pole. It acts relatively the same as the big Chain Chomp, only it deals less damage. When it's pole is ground-pounded on, the Chain Chomp will be let loose, jumping around the place before jumping out of the course into the skybox, being considered 'defeating.' Small Chain Chomps have been reported to be found in the stages Bob-omb Battlefield, Whomp's Fortress, Tiny-Huge Island, Tick Tock Clock, and Tall, Tall Mountain.
