Deuce is fooling around in Silas Sterne?s weapon room. He and Zack had just finished a conversation about trust. And then Deuce goes and turns on a weird butt fighting orb that causes them to switch bodies! Zack is now Deuce and Deuce is now Zack. And oh, tonight just just happens to be the Spanky Awards where Zack is up against Eleanor for butt fighting rookie of the year. Ehn, it?ll probably be fine. He can trust, Deuce, right? / Harmony Day is the one day of the year where all humans and butts come together in the spirit of peace and togetherness – to squash someone! One unlucky human or butt will wear the golden plunger atop their head and roam through the streets until sundown, hiding from the entire town. And Deuce, totally misunderstanding Harmony Day, stuffs the ballot box with only his name so he?ll “win.” Now Zack has to protect his pal from the entire town, including the Harmony Day champion, Silas Sterne.
