Princess Gwendolinda is the princess of the kingdom of Tinkerdee in the Tales of the Tinkerdee pilot. A "pure and sweet young thing," if a bit simple-minded, Gwendolinda is the beloved daughter of King Goshposh. Her birthday party is the focus of the Tinkerdee pilot's plot.

Another simple puppet named "Princess Gwendolinda" was later featured in a skit in The Muppets on Puppets.
