Ash and his friends arrive at a town where many of the town’s children are disappearing. They discover that a Hypno, a hypnotic Pokémon is responsible. Adults in the town have come to help their insomnia by being put to sleep by Hypno. However there is a side effect, making the children think they are different Pokémon and run away and put real Pokémon to sleep. Ash stops Team Rocket from stealing Hypno and uses the Pokémon, Drowzee to bring all the children and Pokémon back to normal. A useless Psyduck follows Misty around, and after she drops a PokéBall, Psyduck activates it and captures itself, much to Misty’s dismay.
