Ash and his party arrive at a port where the SS Anne, an international cruise liner, is docked. Receiving free tickets, from a mysterious duo, for a Pokémon Trainer party aboard the Santa Anne, they board the ship filled with anticipation of good food and lots of Pokémon excitement. Aboard the ship, bustling with Pokémon Trainers, Ash meets a distinguished gentleman who suggests they make a Pokémon trade. Ash exchanges his Butterfree for the gentleman's Raticate. Just then, the SS Anne is taken over by Team Rocket who had arranged the party as a ploy to steal Pokémon. (thetvdb.com)
