Hershey: a guinea pig (breed: rex) who hates chewy, tolerates Cozy and Pepe. Hershey spends most of his time with Cozy, because Cozy doesn’t like Chewy. He is very vocal. He looks like a small capybara (g.p’s. are related to them) All guinea pigs can only communicate by making these sounds: WHEEK (usually wants food [a lot]), Teeth chatter (when either scared, or fighting with another guinea pig), rumble-strut (usually to assert dominance), and complain (when another g.p. is nearby while eating)
