Pelipper attacks Ash's Treecko with a Vine Whip. It then attacks Taillow with Flame Thrower. Finally, it attacks Pikachu with a Thunder Attack. Ash and crew are amazed—Pelipper should only have Water and Flying type attacks, but somehow it knows Grass, Fire and Electric type attacks! That's not physically possible! Team Rocket decides that they must have this awesome Pokémon, so they, too, challenge Anthony. This time, however, Anthony panics and the truth comes out. Pelipper has been hiding Poké Balls inside its large beak. Rather than being disappointed, Team Rocket decides that this is an excellent opportunity. They blackmail Anthony and use his Pelipper for a new challenge. This time, trainers will lose their Pokémon if they lose to Pelipper. Team Rocket's latest hoax is very successful at first, and they con many trainers out of their Pokémon, but they soon get carried away. They fill Pelipper's beak up with so many Poké Balls that when Pelipper does a Water Gun attack, all of the Poké Balls spill out!''

From this, they learn that Pelipper could perform the unusual attacks because its mouth houses a Bellsprout, a, and a. As a result, Team Rocket blackmails Anthony and Pelipper into cooperating on their latest Pokémon-stealing scheme.

At the Pokémon Center, as they are waiting for Ash's team to heal, Max becomes convinced that Anthony is cheating somehow, while dismisses it as the real world not matching up with Max's perceived knowledge. Just then, Trainers begin to pour in, saying that their Pokémon have been taken by the world's most powerful Pokémon. However, suggests that Anthony had been coerced. When the group arrives at the Gym, Jessie and James, disguised as promoters, are announcing a challenge where Trainers have to battle Pelipper, with the winner taking both Pokémon.

As a precaution, Jessie and James place more Poké Balls inside Pelipper, as well as, who will act as a tactical controller.

As the rematch begins, Pelipper starts with Bellsprout's Vine Whip, which Pikachu manages to dodge. Meowth, inside Pelipper, then switches to Magby for a, but it wells up inside Pelipper's mouth, affecting both Meowth and Magby in addition to Pikachu. As Meowth brings back Bellsprout for a, Max wanders off and finds Anthony, bound and gagged; he confesses to cheating. Meanwhile, Meowth comes up with a plan to defeat Pikachu by dousing him with a, then using Thunder on him to deal more damage. However, because he cannot find any Water Pokémon in the Poké Balls, Meowth chooses to use Pelipper itself to fire the Water Gun. As he does so, Pelipper shoots water everywhere, dousing everyone and exposing Team Rocket's scheme. As Team Rocket tries to escape with the stolen Poké Balls, they are attacked by Pelipper's, which frees their Poké Balls. When Team Rocket tries to take Pikachu as a last resort, Pelipper uses Water Gun to soak the balloon, allowing Pikachu to use Thunderbolt. The attack short-circuits Team Rocket's electricity-proof suits, sending them flying.

Anthony ultimately closes the Gym down and decides to use Pelipper fairly, as it was powerful even without the Poké Balls in its mouth.

 * During the fight between Pelipper and Pikachu, it was shown that Pelipper's mouth was heavy and filled with Poké Balls that Team Rocket had put in there for Meowth to choose the Pokémon. However, soon after Anthony's fraud is discovered, Pelipper's mouth seems back to normal.
