Ash and his friends are on their way to the Battle Frontier, and Misty joins them for a while as she heads back to Cerulean City. But Daisy calls to ask if she can start giving away Gym Badges—Misty just can't get a break! Brock has left his Ludicolo at home, May is delighted with her new Squirtle, and Max is eager to see Pokémon that live on nearby Mt. Moon, like Cleffa. Sure enough, a Cleffa appears.
So does Team Rocket and their Poké-Vac 5000, which manages to vacuum up all of the kids' Pokémon except for Pikachu. Except Team Rocket accidentally ejects the Pokémon right back out, the Poké-Vac breaks, and in the confusion as Team Rocket blasts off, Cleffa, Misty, Max, Pikachu, and Azurill all fall in a river!
Misty and Max get back onto dry land and start to look for their friends. Easier said than done, as they run from Beedrill and take cover from a rainstorm. Meanwhile, a Clefairy and Clefable team up with Ash and May to find Cleffa. Just as they find Misty, Team Rocket shows up to spoil the reunion.
Clefairy, Clefable, and Cleffa call for backup, and Team Rocket is on the receiving end of a super-powerful Metronome—Solarbeam combo, with Munchlax on the assist. That's it for Team Rocket until next time! That night, Ash and his friends watch a Pokémon moondance, and in the morning he and Misty go their separate ways once more.
