The group are headed towards Mandarin Island on Lapras. When they arrive there, they see a person being attacked by some Pokémon. As they go to investigate; Pikachu stops, turns around, and attacks Ash. Togepi jumps out of Misty's arms. Then a group of Magnemite surround Ash, shocking him. To create a distraction, an Electrode rolls by and explodes in front of Ash. When the smoke clears Pikachu and Togepi are gone. They find out from Officer Jenny that the same thing has happened to many others. They believe it is some sort of psychic Pokémon behind all of this, because Jenny's Gastly is not effected. Meanwhile, Jessie and James are on the island and Meowth suddenly goes bad. They follow him to the source of all this, it is the work of Butch and Cassidy. They argue over the correct way to say the motto. They then send their evil Pokémon on Jessie and James. When they wake up a bit later after being unconscious they are with Ash and the group and Officer Jenny. Although not wanting to help, they agree to tell them who is behind this and come up with a plan. Jessie and James return to the building with a huge cart of Pokéballs. The rest of the gang are hiding inside. Once in; Ash, Misty, Tracy, and Officer Jenny burst out of the cart. The brainwashed Pokémon begin to attack, and Ash rushes to get Pikachu. Gastly protects Ash from the attacks, and he gets to Pikachu. Ash taunts Pikachu into attacking him, and he dodges the thunderbolts. Ash rushes towards the machine that which have been amplifying the Drowzee's psychic waves that have been causing all of this. Pikachu's thunderbolt, besides shocking Ash, destroys the machine. Pikachu and all the other Pokémon revert to their normal selves and return to their trainers. Outside of the place, they battle Butch and Cassidy. Drowzee tries a metronome attack, and Togepi starts one simultaneously. The whole building explodes, and it was because of Togepi's metronome. After receiving an award, Ash and the others get back on Lapras to head for the next island.
