Billy has a light pink-colored shell like Gary, but is lighter and glossier, and on his shell, there are no dots: just red lines like Gary's, but much thinner. He has green skin with a blue underside, styled black hair, and blue eyes. He has a brown leash and appears to be more anthropomorphic than most snails.
Role in episode
- When he says "meow," instead of saying it like most snails, his meow sounds like a human man's.
