The Stegosaurus is a recurring Unisaur hand puppet used on Dinosaurs. The stegosaurus was used exclusively as a background character, usually silent. His most notable speaking role occurred in "And the Winner Is...," as the government clerk present when the Chief Elder dies of a heart attack. The puppet also surfaces as a newsboy ("Charlene's Flat World"), a USO soldier/stagehand ("Nuts to War"), a caroler ("Refrigerator Day"), and several times as a student at Bob LaBrea High School.
