Frazzle is the only Muppet monster intended to be "scary" in the children's television series Sesame Street. During the late-1980s to early-1990s, his career was limited to that of a background extra, due to his creepy annoying appearance. He was often put on lawns to scare children away With the exception of one episode, Frazzle always talks in babyish monster sounds.
