Ash finally begins his training for his rematch. Meanwhile, Nurse Joy comes down with the flu. In the woods, Team Rocket finally makes it back to Fennel Valley after being attacked by Harley’s Cacturne. When trying to chose a path at a fork in the road, they cause a Gloom to use stun spore on an Electrode, which rolls down the hill and explodes on the front of bus carrying pokémon. With Nurse Joy sick, Brock and Professor Oak must take care of all these pokémon while Ash helps Matt get his Bagon back after it runs off. Team Rocket, in the meantime, decides to steal all the pokémon.
