Chain Chomp

The Chain Chomp is an enemy in Super Mario 64, appearing in Bob-omb Battlefield. It is a large black sphere with a mouth and eyes, connected to a wooden pole via a chain, hence the name. It hops around the area it is in, and will lunge towards the player when they walk nearby. The Chain Chomp does damage to the player upon contact.

If it's pole is ground pounded 3 times, it will hop around, break the bars of the cage behind it, and jump away. This will give the player access to the "Behind Chain Chomp's Gate" mission's star.

Alternate Manifestation
Some people have said the Chain Chomp has appeared outside of Bob-omb Battlefield, acting similarly. However, others have stated that it can appear in other levels after being freed, hopping around until the player draws near. When the player is spotted, it will rush towards the player. A similar behavior is seen in Super Mario 64 DS' silver star mission.
