DEBUT 1987

Professor D. Rabbit appeared on Sesame Street during Season 19. In one episode, he appears in a segment with The Amazing Mumford in the courtyard. He agrees to be the rabbit that Mumford finally pulls out of a hat on one condition: he wants to pull Mumford out of the hat afterward.

Professor D. Rabbit appears again in a later episode to teach Big Bird how to be a good listener.

Years later, the puppet was used as an unnamed rabbit (performed by Martin P. Robinson) in a season 38 episode, anxious to have his electric teapot fixed at The Fix-It Shop before his tea party. The puppet later made various background appearances on Plaza Sésamo during season 11.
