Bye Bye Pikachu

On their journey, the friends stop for a rest in a forest. There they encounter a large group of Pikachus. After some trials, the group of Pokémon befriends Ash's Pikachu. They celebrate their friendship in the moonlight. Ash considers leaving Pikachu with its own kind. Brock goes to sleep, leaving the Pikachus to celebrate amongst themselves. Misty, however, wants to join the festivities. She hadn't expected the celebration to turn into a sex orgy.
