Wakko Warner Wakko Warner is one of the three main protagonists of the TV series Animaniacs. He is the middle child of the Warner siblings, and the oddball of the three. He wears a red baseball cap along with a blue sweater. In the revival he has grown a small tuft of hair on the top of his head (a smaller version of his hair tuft was briefly seen in the original show during The Senses Song.) As a symbol of his wackiness, his tongue occasionally hangs out of his mouth.
