A well-animated children's adventure produced in Japan, dubbed into English for American release. A young girl dreams of an enchanted land where the king's daughter has been transformed into a sleeping mouse, whereupon an army of evil mice steal the princess's heart. Luckily a young hero
arrives and retrieves her heart so that she can become a normal person once again. Of course they fall in love and everybody's happy at the end. Outstanding voice talent from Gilbert, Lee, and McDowall, combined with cute songs, makes this a good one for the kiddies.
