Mr. Gus

Mr. Gus is a green dinosaur, somewhat tall, somewhat fat and apparently disinterested in the follies of Uncle Grandpa and wearing a white sleeveless T-shirt.

A dinosaur, which has lived more than a million years on Earth. He does not even bother about eccentricities. Gus has a more serious personality than the others, and he can be direct and emotionless. Gus acts as a paternal figure for Uncle Grandpa.
