An opera singer features in the song "Music of the Street" in episode 4081 of Sesame Street. Miles and Gabi are trying to illustrate to Rosita that everyone has a different way of talking that makes them sound unique. This woman appears to demonstrate that some people speak in song. She also appeared during the song "Everything's Coming Up Noses."
The puppet is wearing the same "fat lady" opera singer outfit worn in its final appearance as Big Head.
