Ep 9. Hold the Phione!

Dawn, Ash, and Brock arrive in Chocovine Town to find everyone in a festive mood. It's not the upcoming Contest that has everyone excited?it's the annual visit of the Phione! These rare aquatic Pokémon can be seen near town and are said to bring good luck. That night, Dawn and her friends take a Phione-watching tour on a submarine, unaware that the submarine is crewed by Team Rocket. Three Phione swim past the submarine, and one of them is so interested in Dawn's Buneary that it stays behind after the other Phione have continued on their way. After the tour is over, Team Rocket returns and snags that lone Phione in a net, but makes the mistake of letting it out for a swim in the town fountain. Phione uses Acid Armor to escape down the drain so it can search for Buneary.
