Little Jimmy was originally from a newspaper comic strip created by Jimmy Swinnerton. The title character was a little boy who was constantly forgetting what he was supposed to do and ended up getting into trouble. Betty sings the song "Keep Your Girlish Figure" and Little Jimmy responds with a verse "If you're thin, don't worry over that. Just begin to laugh and you'll grow fat".
Little Jimmy's voice was provided by another female voice-over artist who worked for the Fleischer Studios, either Bonnie Poe or Margie Hines.
