Go Go Ludicolo! - S7.E27

While having sandwiches for lunch, the heroes are visited by a man named Poncho and his Ludicolo. They challenge Ash to a battle, who bets his sandwiches with Poncho, who is to buy cheeseburgers if Poncho loses. Corphish volunteers for the battle, but it seems distracted and eventually loses. This infuriates Corphish even more, who runs off while the heroes try to find out why Corphish is angry.
