They meet a trainer named Benny who is trying to find someone to trade his Wobbuffet to. Ash, Misty, and Brock decide to help him find someone to trade to. Meanwhile, Team Rocket is using the event to trick trainers into giving them their pokemon. However, a run-in with the Magikarp Salesman leads to events that may change the outcome of Team Rocket's plans.
