If I Fell takes place in the castle of a mad scientist. She has created a monster and needs the brain of a beetle. Igor brings John and his brain is transferred into the monster's head. The monster then begins to sing If I fell until Igor switches him off. The scientist then declares, "I've created the world's first singing and dancing monster"! A bunch of screaming girls then run into the castle and destroy the monster while grabbing locks of hair etc. John then somehow gets his brain back and runs away.
