Cricket

About
Cricket is Jeff's cohost and a talking cricket. We do not know her first name, as presumably "Cricket" is her last name. She is allegedly the daughter of Jiminy Cricket. She is also an ethics teacher, although seems to only have a cursory knowledge of ethical philosophy.

Appearance
It is implied that Crick is an anthropomorphic cricket, similar to Il Grillo Parlante from The Adventures of Pinocchio. Early episodes make references to Pinocchio and Pleasure Island.

Affiliation
Cricket tends to align with chaotic good.
