S2·E27 The Little Princess of Darkness

The Cinderella Shadow is a stamp which is said to possess the magical power of making its owner into a princess. Lupin casually steals it from the hall where it is being exhibited, but a girl named Alice also wants the stamp. Not only is she quite persistent, she is smart as well, and tries her best to get the stamp. At the finish of the fantastic chase through the amusement park, where has the Cinderella Stamp gone?
