On their way to Nimbasa City and Ash’s next Gym Battle challenge, our heroes get caught in a torrential downpour. They duck into a nearby mansion to get out of the bad weather, finding no one inside. Upon further investigation, it turns out the mansion is inhabited by a group of Litwick…as well as Team Rocket!
Jessie, James, and Meowth have turned the mansion into their new secret base! When they discover Ash and his friends inside, they ask the Litwick (through James’s Yamask) to capture Pikachu and chase the “twerps” away.
At first the Litwick try to prevent our heroes from learning about them by draining power from Ash’s Pokédex. But eventually, Ash learns that Litwick are known for pretending to guide people through dark places…while actually leading them into the Ghost World. And their flames can drain the life energy of people and Pokémon!
The Team Rocket trio have fallen prey to the Litwick’s flames as well, and all three of them are completely exhausted. They decide to join forces with our heroes to fight against the Litwick, and after some intense battling on all sides, these dangerous Pokémon are sent back to the Ghost World!
Working together, our heroes and Team Rocket all manage to escape from the frightening mansion. But the spirit of cooperation is short-lived, as Jessie, James, and Meowth let Ash know that stealing Pikachu from him is still their number one goal!
