Team Rocket are sent to the Sinnoh region for a vacation, but their break is interrupted by the arrival of Ash and Goh looking for a special Pokémon.

Goh enters his giant Magikarp in the tenth annual Magikarp High Jump Tournament. Then he and Ash head to Slowpoke Island, hoping to catch a Slowpoke.

A Sobble sneaks up on Ash and Goh while they're eating at the Wyndon Pokémon Center. To catch it, they have to follow a trail of crying people.
