Weasel brings Cartman four hundred pounds of teeth from China to pay Loogie for the tooth trade. Cartman kicks him out of his house when he finds out that Weasel was scamming him with four hundred pounds of teeth that were actually cat teeth instead of human teeth, causing Weasel to make monkey noises before leaving.
Weasel has a unique appearance from most other child characters. He has an egg-shaped head and very large eyes. He has small strands of black hair on his head, thick black eyebrows, and a large nose. When not speaking, his large buck teeth are visible. He wears a black coat with a white undershirt, a light brown belt, dark brown pants, and black shoes. He also appears to be slightly taller than most other child characters.
