Bully

Bullies are black spherical enemies with yellow horns in Super Mario 64 and Super Mario 64 DS. They are found in Lethal Lava Land and Bowser in the Fire Sea and can be defeated by knocking the into lava, which yields one coin. This is achieved by jumping on, kicking, punching or diving at them; they always move in the direction Mario is facing. If they see an enemy, they attack by charging, similarly trying to push their opponent into lava.

Big Bullies are larger versions of Bullies, and reside in the same level.
