Mario franchise strategy guide/Bosses/Chief Chilly
Chief Chilly is the name of a stage boss in Super Mario 64 DS. He is a giant version of a bully, and similarly, he attacks the player by pushing him off the platform into a fast-moving current of slush. His level, Chief Chilly Challenge, is accessible only as Luigi via in the Mirror Room in Princess Peach's Castle. (The same room houses the entrance to Snowman's Land.) To defeat Chief Chilly, the player must push him off the platform by punching. After three hits, he gives the key to unlock Wario.
