With Azalea Town as their new destination, Ash and co. take a break in a valley. While they were sleeping a Sentret child catches Togepi and they fall into the opening of Team Rocket's new Arbo-Tank. After they wake, Misty notices Togepi is gone and, like a mother, is worried sick about it. She, along with Ash, Brock and the Sentret's mother, meet up with Team Rocket and try various plans to stop the Arbo-Tank. Will they succeed? And will Togepi be grounded by Misty for wandering off and looking for trouble?
