As they enter the city, Jessie and James, disguised as Hawaiian women, kiss Ash and put leis on him. They welcome Ash and his friends as the one-millionth, one-millionth and first, one-millionth and second, and one-millionth and third visitors to Saffron City and take them to a building to receive their prizes. Upon arrival, James grabs Pikachu with rubber gloves and Jessie pushes the three onto a warp tile, sending them to an isolated room with no exit. A television screen drops down and Team Rocket remove their disguises, revealing that the prize-winning welcome was part of a ploy. Team Rocket recites their motto, but Ash and his friends ignore them. Ash orders Pikachu’s return before the monitor cuts out. As Jessie and James work to fix it, Meowth points to a little girl, the same one Ash saw earlier. She emits a blue aura and stops Jessie and James from moving. The girl takes Pikachu and teleports into the same room with Ash to return Pikachu. Ash thanks her, but the girl glows again and points to Ash and his friends, teleporting them.
