There was confusion when Lum was born. A slight miscalculation at the post office resulted in a witchy friend of the family to not get their invitation to the celebration. The witch was mad and thus put a curse on Lum, that she would never become happy when she found true love. Present day, and amusement park was just completed and was opening for the first time in Tomobiki. The whole gang decides to head over it to have some fun. At a magic show however, Ataru gets turned into a large pink hippopotamus! When Lum attempts to track down the magician that transformed her darling, things begin to get weirder and weirder very fast!
