Spell of the Unown

Ash and his friends encounter a little girl named Molly Halle. Her loneliness draws the attention of the mysterious Unown, and whenever Molly starts to cry, they grant her a wish. They summon the legendary Entei, which Molly now sees as a father figure. After Ash and his friends stop Entei, the Unown go berserk and can only be calmed down by Misty. They then retreat to their own dimension.
