Chain Chomp

Chain Chomps are ghosts inhabiting balls, usually ones made of iron. Their demeanor is that of a wild dog; barking, biting, and thus found leashed up. Because of their dog-like behavior, they're often adopted as pets by owners.

Description
Previously, these spirits used to inhabit balls of stone to form Stone Chomps. These chomps were used as guard dogs to guard the treasure of Dry Dry Ruins. Nowadays, Chain Chomps are created from iron balls. Golden ball variants of Chain Chomps exist, but are quite rare.

Chain Chomps are very tough orbs, with a large mouth sporting many sharp teeth. They're very excited and willing to pounce on anyone coming close-by. It's because of this that they're leashed up via a chain, but that doesn't stop them from charging at anyone coming by.

Life Cycle
Current Chain Chomps are created in factories, a notable one being the factory in Chompworks Galaxy. Chain Chomps can grow up over time, becoming many times their size.

When the body of a Chain Chomp is destroyed, the spirit leaves it behind, presumably to inhabit another body. Otherwise, the spirit leaves the Chain Chomp body behind, leaving behind a blank ball with a chomp-indent on it. This is best seen with Stone Chomps leaving their bodies, resulting in a Chomp Rock.
