After Ash and his friends offer their assistance, Jenny escorts the group via jeep to the signal location, where they find Team Rocket trying to capture a group of Kangaskhan. Ash looks at his Pokédex, which says the Kangaskhan charge when in danger until they feel their young are safe. Team Rocket fires a rocket, which scares all the Kangaskhan and makes them charge towards the jeep. The group manages to escape, but Team Rocket traps all of the Kangaskhan in a net. Team Rocket pulls up in a red jeep, with a box full of Poké Balls, and admire their catch. Jenny is unable to do anything, with the jeep engine now overheated because of an earlier incident. Jessie throws a Poké Ball, but it is hit by a boomerang and sent flying back at her. Suddenly, a kid begins to yell and swings in on a vine; he cuts the net with his boomerang and sets the Kangaskhan free. The boy orders the Kangaskhan to attack Team Rocket. They are quickly surrounded and receive several tail whips before the final spinning blow is dealt and they are sent blasting off. The kid jumps into the pouch of the biggest Kangaskhan, and after his command, the entire herd walks away. Ash admires the boy’s ability to communicate with the Pokémon.
