Ash, Pikachu, and Brock take a break by the lake while Misty heads deeper into the forest with Togepi. As Misty picks some flowers, Togepi wanders over to a very strange looking bush. It appears to have legs...spider legs! Summoned by Misty's shrieks, Ash and Brock discover an Ariados in the bush. Just then, Aya, Fuchsia City Gym Leader Koga's younger sister, appears before everyone. She is happy to see them again and tells them that she is studying Pokemon Jujitsu at a nearby Dojo. She invites them to the Dojo where they all decide to take part in the different classes. However, Team Rocket is once again planning to strike and steal as many Pokemon as the can.
