The song "Little Bunny Foo Foo" is mostly sung by Happy along with Queen Delightful in "Hop To It, Dopey!" The main version that opened the segment described Little Bunny Foo Foo attacking the field mice with his mallet while Delightful is looking for him and disapproving of his actions, and the reprise has Foo Foo being married with Woo Woo and having offspring. The song's melody also plays several times throughout the episode.
