Ash and friends come across a school where a girl named Olesia takes care of some Wooper. She needs to run and visit her mother, but she can't take the Wooper with her. Ash, Misty, and Brock agree to watch them for her, but it turns out to be more then they bargained for.

A group of wild Houndour is stealing stuff from people in town and terrorizing people in the forest, and people are becoming scared of them. But when one of them is attacked by a wild Golem, Ash and friends befriend them and make the long trek back to town to help the poor Houndour.
