Shivers the Penguin was a character who appeared on Sesame Street a few times during the late 1970s to early 1980s, including an appearance in Big Bird in Australia. The puppet was designed so that Shivers could be carried by Big Bird or sit on Big Bird's lap, allowing Caroll Spinney to perform both characters at the same time, with his left hand manipulating Shivers' mouth while his right hand worked Big Bird's mouth. On at least one occasion, the characters sang a song together.
