While heading to Coumarine City, Ash & Co. decide to stop off in a forest to relax. With everyone relaxing in their own way, Bonnie decides to explore the nearby area with Dedenne. On exploring, she meets up with three kids who call themselves the Lapras Defense Corps due to the fact they are looking after an injured Lapras. As Lapras is nearly healed, it seems rather sad so the kids decide it's time to release it back in the ocean. However, as they go to do so, Team Rocket appears to try to get the Lapras. Without having Pokémon of their own to defend Lapras, will the kids be able to get it back into the wild and hold off Team Rocket?
