Chill Bully
Chill Bully is a giant Bully found in Super Mario 64. It has a tie-dye blue surface and a single golden spike on the top of its head (as opposed to the usual black surface and twin horns of normal Bullies). Chill Bully appeared in Course 10: Snowman's Land. In this level, Chill Bully walked around on an ice platform above a pool of extremely cold water. After Mario defeated the creature, he earned a Power Star.
Chill Bully looks a lot like Chief Chilly. This means Chief Chilly may have some unknown familial relation to Chill Bully. It is also possible that Chill Bully is not a unique Bully, but a variety of Bully. As such, Chief Chilly could be a unique member of the Chill Bully sub-species.
In Super Mario 64 DS, the player can beat it easily with Yoshi, and then eating a power flower. Once the fire touches Chill Bully, he wil fall into the ocy cold water.
