Dusty

Dusty is a Grouch who appeared in a 2001 episode of Sesame Street as the drummer of Oscar's "alternative" Grouch band. He became so incensed that he doesn't get to start the band and quits. Apparently, Elmo has a drum and with a little help from Oscar, Grundgetta, Slam and Phooey Louie, he became the drummer replacement for Dusty.
