Knuckle Joe has returned -- and this time, even more injured than ever, for one thing -- Masher! Meta Knight delivers him to Amy's house, where Tiff is currently in. Amy and Tiff feed the monster hunter some medicine, then he tells them stories about his now-dead father and how he grew up to be a monster hunter. Suddenly, Masher appears in the Station Square City Park, and it's up to Knuckle Joe (and some of his new friends) to get rid of it for good.
