Meowth manages to talk to the Beartics, which obviously fails. As those Beartics are fuming whil using Icy Wind on them, they are saved by a Martial Arts Pokémon: Mienfoo, which belongs to a ranger named Cliff. After trying again, Meowth and Cubchoo fall down with Axew, Pikachu, Oshawott and Tepig down into the forest below. Can they find their way back? And what are Jessie and James planning with the subway system in Nimbasa City?
