Crusty the Cat debuted with the rest of the Pizza Time Players in 1977, at the first Pizza Time Theatre location in San Jose, California. Crusty was nicknamed "The Cat's Meow" in singing and joke telling, and was Chuck E.'s right hand man.
After appearing in the first two showtapes, he was replaced by Mr. Munch in 1978, making him the first character to be retired. He was voiced by John Widelock, who also provided the voice for Chuck. However, Crusty never made it out of the original Pizza Time Theatre location.
