Chesby is Zombie Carl's pet worm. Carl plays with him often while residing in Spookane and at the Boudreaux Mansion when working as a butler. Although Carl says he is a worm, Chesby is really a dwarf swamp eel. Chesby appears to live in Carl's head, since he comes out of his master's ear sometimes. He appeares to be small and green mostly resembling a worm yet happens to be an eel.
