When Peter embarks on an enchanting quest to save his younger sister Anne, he must venture into an enigmatic realm: the Moon! Anne was taken by the sinister Moon Man after she attempted to assist the beetle, Mr. Zoomzeman, in his quest to find his wife. During his extraordinary journey, Peter arrives at the Star Meadow, where he encounters the drowsy Mr. Sandman. He learns that only at the Night Fairy’s banquet in the cloud castle can they discover Anne’s whereabouts—but there aren’t enough places for everyone. Thus, they engage in a thrilling race along the Milky Way against the five Spirits of Nature: Storm Giant, Lightning Witch, Henry Hail, Rainy Robin, and Mother Frost.
