Squirmy is a cousin to Slimey, Oscar the Grouch's pet worm. She appears in the 1983 book The City Worm and the Country Worm. She has a sweet temperament and lives in an apple. When the book was adapted to video form in 1985 in Three Sesame Street Stories, Fran Brill voiced the character, using a voice identical to the present-day Prairie Dawn with a slight Southern accent.
