When Professor Spencer Hale suddenly disappears, leaving his only daughter Molly alone and lonely back at his mansion. When a shipment of tiles from the ruins arrive at the mansion, the girl's depression and desire for companionship invoke the Unown trapped within them. As Molly wishes, they use their reality-warping powers to seal off the mansion and the surrounding valley of Greenfield in crystals and create an image of the legendary Pokémon Entei to stand in for her father. When Molly wishes for a mother (who had also vanished), Entei kidnaps Ash's mother Delia and brainwashes her into thinking she is the girl's mother, prompting Ash to charge head-first into the mansion on a rescue mission to not only save Delia, but also everyone else from the increasingly destructive powers of the Unown, who are more and more manipulated by Molly's impulses and feelings, crystallizing more and more of the environment within the mansion's vicinity.
