Cocco

Cocco (コッコ) is a large hen-like children toy robot enemy from Mega Man 5. It produces a continuous stream of Corocoros that try to ram into Mega Man. It has been known to lay up to three Corocoros at a time. Their weak spot is their head. They appear in Gyro Man's stage, Charge Man's stage, and in some of the Wily Castle stages.

Corocoro
Corocoro (コロコロ) is an walking egg-like enemy robot that comes out of Cocco. If an obstacle is in the way, they either hop over it, or attempt to leap over it and then turn around (depending on the blockade's height). Other than that, it has no more attacks. They can be destroyed easily with a normal shot from the Mega Buster and often drop useful power ups.
