Chain Chomps are common enemies in the Mario series. They first appeared in Super Mario Bros. 3. Chain Chomps bear a resemblance to a ball and chain and are typified by their large, tooth-filled maws and incessant biting. Shigeru Miyamoto’s inspiration for the Chain Chomps was from a childhood experience: a dog once ran up to him and tried to bite him, but the dog’s chain held it back.
