Winky is a "happy little beaver", who is the innocent victim in "Swift Wits" segment of Muppets Tonight episode 105. Buster and Colfax Bergman, the only multiple contestants on "Swift Wits," attempt to save Winky from being eaten by Carl, the Big Mean Bunny. For every correct answer, Winky would get a log for his dam. Unfortunately, the brothers' over-enthusiasm costs Winky his life.

The puppet was originally built for Morton the Beaver for The Animal Show.

On Sesame Street episode 4202, the puppet appeared in the woods where Chris and Elmo are camping at.
