While Pikachu, Togepi and Psyduck are sleeping on Lapras' back, Psyduck slips off and into the water. They search, but cannot find him, until a girl named Marina comes by because her Tentacruel had found Psyduck. They notice the tail is glowing, and Marina says that's a sign it's going to evolve. Marina knows a lot about water Pokémon, as does Misty. The two girls decide to have a battle. During the battle, when Misty goes to use Psyduck, she notices the pokéball is empty. She asks Ash to throw her the bag, but he doesn't throw far enough and it lands in the water. When Misty goes to recover her bag, there is a Golduck hanging from it. She believes it to be hers and starts to use it in battle. Team Rocket intrude, and capture Marina's Tentacruel and Psyduck, but Team Rocket are defeated easily by Golduck. Misty then battles Marina with Golduck and wins. When Misty pulls out her pokéball for Golduck, her Psyduck comes out. They are all a little confused for a while until they realize it was a wild Golduck, simply it likes to show off for girls, as it sees three girls walking by, it runs off to meet them, leaving Misty behind.
