Momo and the others have succeeded in escaping the cursed trunk and defeating the Fairy-Tale Card, but because Momo ate the sweets inside the trunk, she has shrunk to the size of a fairy! While her grandma looks for a way to return her to her previous size, Momo heads back to school in her new, tinier form. It's there that she hits on the idea to research fairies in the library, and once there, she spots…a pygmy?!
