Misty thanks the girl, who introduces herself as Marina. She points at Psyduck’s glowing tail, and says that a Trainer once told her that when this happens, the Psyduck is about to evolve. Ash checks his Pokédex and it tells him that Golduck, Psyduck’s evolved form, is the fastest of all Water Pokémon. Both Misty and Marina say that Golduck is one of their favorite Pokémon. They talk about Water Pokémon for a moment, completely ostracizing Ash and Tracey. After showing each other some lures they made and wishing they could catch one of the legendary Pokémon of the sea, Marina asks Misty why Psyduck cannot swim, since she found it flailing in the water. Misty claims that it was because it was a rare breed. Marina suggests that they battle each other to see which is the most powerful Water Pokémon Trainer, and Misty agrees.
