With a new Pokémon in tow, Ash continues his training to prepare for his rematch with Brawly. However, though caught, Corphish is still a ruffian as it introduced itself by whacking all the other Pokémon on the head. Can it ever be more social with other Pokémon, and why is Jessie's Silcoon purple right after it evolved?
Ash is cleaning the Poké Balls for the next Gym fight. Corphish eats rope, even if Ash warns it that it ain't food, but Corphish blasts Ash to a tree and runs off. Later, Ash introduces Corphish to other Pokémon, but Corphish pounds everyone. Everybody is eating, but May worries for Wurmple who is not eating. Even Torchic offers food, but Wurmple does not eat, so Corphish eats it instead.
Team Rocket arrives, catching Ash's Pikachu. As always, Pikachu cannot use electrical attacks due to anti-proof cage. Wurmple uses String Shot, catching the balloon. Team Rocket lights the fire so balloon can go higher. Corphish goes to help them (on Ash's behalf), but it cuts the string. Team Rocket goes away, but this time they have Pikachu.
However, the gang arrives and Corphish uses BubbleBeam, making Pikachu being thrown away. James brings Cacnea to fight, with Jessie following with Seviper. Seviper grabs the cage, but Wurmple uses String Shot to take the cage as well. Jessie brings Wurmple, as a reaction to May's. Jessie brags how her Wurmple is great, but both Wurmple begin to shine - to evolve. The Wurmples evolved into a Silcoons, but James and Meowth notice how Jessie's purple and May's is white.
Cacnea uses Pim Missile, but Corphish uses Crabhammer. Pikachu uses Thunderbolt to blast them away. Everyone cheers, but Corphish suddenly falls down, being ill. Since the Poké Balls are far from Ash, he is going to carry Corphish to Pokémon Center while the others wait. Corphish is getting more ill, so Ash gives it some cold water. Ash is starving, but Pikachu spots berries. A Shroomish appears, using Stun Spore, so they go away.
Brock is making stew and May wonders if they are in Pokémon Center yet. Ash is crossing the river, but is intercepted by Carvanha. Pikachu spots a boat, so they go on it. Carvanha appear again, but Pikachu uses Thunderbolt, making for Ash safer to cross. More Carvanha appear, biting the boat. Ash goes back to the coast. Ash tries to find a bridge (and he does, but it is destroyed), so he has to cross the river. Carvanha intercept Ash, but he still continues. Pikachu jumps to coast and uses Thunderbolt to keep the Carvanha distracted.
More and more Carvanha appear while Pikachu electrocutes them, the rest attack Ash. One hirs Pikachu, so they all attack Ash, but Corphish attacks them with BubbleBeam. Ash makes it to Pokémon Center - Nurse Joy treated him, so everything will be okay, even if the Corphish ate rope. Back at the camp, a noise is heard, so Brock, May, Max, Taillow and Treecko go to check it out. May spots something - an audio recorder. They all get caught in a trap Team Rocket set up.
The Taillow is free, but Team Rocket thinks they got Pikachu, but they see two traps have been activated. James stomps, activating the third trap and encasing Team Rocket. Treecko attempts to break out, but with little use, with the sea level becoming higher. Ash and Pikachu stay near Corphish. The next morning, Taillow comes to Ash with the recorder - everyone on the beach will drown if Ash does not intervene.
Ash arrives, ordering Corphish to use Claw Hammer to destroy the cages. Team Rocket offers their gratitude, but they soon plan to steal Pikachu. Pikachu uses Thunder and Corphish BubbleBeam, blasting them off. May and Max thank Corphish, and it thanks them - by pounding them.

- "Yeah." - Max
- "Character is another word for troublemaker..." - May

- Jessie thought that her Wurmple evolved into Silcoon, but it wasn't until "Seeing is Believing " that she realized that it evolved into Cascoon because after that it would evolve into Dustox.
