While training on a beach, Suiren's Ashimari and Satoshi's Mokuroh are caught inside one of Ashimari's balloons, which is blown away by a strong wind. Mokuroh bursts the balloon open, which sends them crashing into Rocket-Dan's secret base. Nyarth and Hidoide chase after them, but they are rescued by Nyabby. While Satoshi, Suiren, and Mao search for the missing pair, Nyabby takes them to where it has been staying with the old Mooland. The Mooland asks Nyabby to help them find their trainers. However, Rocket-Dan is also hunting them. Who will find the lost Pokémon pair first?
