This film is one of two children's features (the other being The Magic Land of Mother Goose) directed by Herschell Gordon Lewis, who is best known for his gory splatter films from the 60's such as Blood Feast and Two Thousand Maniacs. The film was shot in Florida in 1966, so it has that Ice Cream Bunny feel to it. This movie is all kinds of awful, but in a way that's perfect for Rifftrax.
