Ditto's Mysterious Mansion
Being caught in a sudden rain shower, our heroes are obliged to seek shelter. In the middle of a clearing, they find a small, ghastly cabin. Dragging the reluctant Misty, Ash and Brock enter the cabin, instantly getting the impression that they are not alone. Could this be a haunted cabin? They soon discover that it is the Copycat house in which the trainer of Ditto lives. Intrigued by Ditto, Ash proposes a battle between Ditto and Pikachu.
