Chain Chomps (or Chomps) are common enemies in the Mushroom World, first appearing in Super Mario Bros. 3. Chain Chomps bear a resemblance to a ball and chain. They are a strong, animal-like species with sharp teeth and commonly used as guard dogs in most games. The presence of ancient statues of them in the Dry Dry Ruins suggests that they have been used as such for centuries. Many Chomps in the Mario series have been part of the Koopa Troop, though a couple of them have been shown to be independent.
