Frog (Nicked by a Name)

An unnamed frog is seen in Brain's fantasy giving him an account of some sort because of the successful nicknames created for his friends. The account is given to Tom Tapir after Brain can't think of a name for Arthur. Although the unnamed frog only appears in "Nicked by a Name," he does have a minor speaking role throughout the fantasies.

Physical appearance
He is a green frog who wears a blue-green tuxedo and teal tie.
