As our heroes head towards Veilstone City, Ash's new Chimchar struggles to adapt to its new surroundings. Everything is the complete opposite of life with Paul: mealtimes are fun and everyone treats each other with friendship and kindness! Chimchar still has vivid memories of the lonely and harsh treatment it received from Paul, so this sudden reversal of fortune is nearly too much to take. When Ash even praises Chimchar after it loses a practice battle with Dawn's Piplup, Chimchar breaks down in emotion.
Meowth, who's searching for Team Rocket after their group was split up by some rampaging Zangoose, sees this scene and has a pang of sympathy for Chimchar. That night, Chimchar can't sleep and it finds Meowth sitting in the moonlight. Meowth isn't in the mood for a fight; instead, it gently tells Chimchar to make the best of its new life. Of course, all bets are off the next morning once Meowth rejoins Jessie and James: they catch Dawn and Brock by surprise, then try to steal all of their Pokémon by trapping them in giant canisters!
But when the Zangoose show up, Team Rocket has to hide in the canisters for their own protection. Ash and Chimchar reach the scene and realize the Zangoose are about to knock the canisters off a cliff! Chimchar has encountered Zangoose before and it's still afraid of them. Ash knows this, so he encourages Chimchar and gives it the confidence it needs to take on and defeat the Zangoose. With everyone safe and sound, it's three cheers for Chimchar, who finally feels like a part of its new family!
