Back at the lab, Ivy shows them the gold Poké Ball. She reveals the inscribed letters on the top of the ball, giving it the name the GS Ball. One of the assistants demonstrates how the ball could not be transported. Ivy also points out how multiple attempts to open it have all failed. Ivy hands the Ball over to Ash to deliver to Professor Oak. Meanwhile, at the airfield, James and Meowth are dismayed by the ruined blimp, but Jessie reminds them that Ash and his friends have a return trip booked. Knowing that it means another shot at catching Pikachu, Team Rocket starts repairing the blimp.
