Whilst Ash and his friends are relaxing in a forest, three Mightyena and a Poochyena ambush them. While they are trying to protect themselves from the Pokémon, they are rescued by the Ranger of the Forest, Katrina. She wards off the wild Pokémon and takes the group to her house. Meanwhile, Team Rocket overhears that the forest is full of rare Pokémon. Back at Katrina's house, Max creates a bond with her Poochyena and tries to make it evolve, with minimal success. Is Poochyena going to evolve and is Max going to understand the importance of evolution?
