Minnie the Moocher defined Betty’s character as a teenager of a modern era, at odds with the old world ways of her parents. In the cartoon, after a disagreement with her parents, Betty runs away from home, accompanied by her boyfriend Bimbo, only to get lost in a haunted cave. A ghostly walrus (rotoscoped from live-action footage of Calloway), sings Calloway’s famous song “Minnie the Moocher”, accompanied by several other ghosts and skeletons. This haunting performance sends the frightened Betty and Bimbo back to the safety of home.
