Princess Tai's greedy uncle is back with a machine that turns kids into zombies...zombies bopping to rock and roll music as they clear rocks from the tunnel to the diamond mine beneath Windom Castle. Enter Fitz, a local boy who helps Willie and Ariel escape as Noah and the rest of the gang are taken to the zombie maker. When he sees his brother, Reggie, disappear in a flash of lights, Willie knows he has to do something before his other friends become zombies, too.
