While Exploring Blue Rock Isle, Ash and co. encounter a Chinchou, an odd Pokémon that's both a Water and Electric type. Misty tries to catch it but fails realizing it belongs to someone else. It does, a boy named Dayton. However, Team Rocket sees the Chinchou and devises a plan to use them as Christmas lights (In September, really?). Later, everyone prepares and celebrates a Chinchou parade. Ash and Dayton lead the parade and Brock, Misty and Dayton's Father are at the end. However Team Rocket blocks the path they need to go. Can Ash stop them and get the Chinchou to their destination on time?
