She welcomes Tracey in the household too. Misty asks Mrs. Ketchum on the amount of time Brock has been staying at her house. Mrs. Ketchum tells a story about how she found Brock.

Kingler jumps into the water and looks very happy. Tracey begins to sketch when he sees Professor Oak peering from his shoulder. Everyone heads back to the lab where Tracey shows Professor Oak his other sketches. Tracey appears to be very nervous. He is so nervous that the whole couch shakes. Suddenly, they see something surrounding them. Team Rocket has the whole lab caught in a tent.
Jigglypuff walks up to the tent. It can't open it and gets mad over this. Ash and co. wonders what happened. Team Rocket appears, and they recite their motto. Team Rocket wonders why Brock is back. Muk appears, and Ash thinks it wants to battle. Muk heads straight for Team Rocket. Jessie sends out Lickitung. Muk passes Lickitung and gets on top of Jessie. James sends out Victreebel. Muk starts to play with Victreebel. Victreebel uses Razor Leaf, but it has no effect on Muk. Victreebel then sticks itself onto Muk. Before Victreebel can attack, Muk's Poison Gas knocks Victreebel out. Lickitung licks Muk, but that attack doesn't effect Muk either. Victreebel uses Sleep Powder which puts Muk to sleep.

He tells Gary that he won the Orange League. Gary congratulates him, but he still didn't beat Team Rocket. Ash and Gary have gotten a lot stronger since the Indigo League. They decide to have a Pokémon Battle to see who is stronger. Who will win?
