The kids challenge the zombies to a series of racing contents around Neighborville. Unfortunately, Zomboss blocks their path with his new invention... the Massive Munch Machine. Can Crazy Dave save the day with a dino-pig statue?
Crazy Dave disappears during the race leaving the kids without a driver, but Nate has a dream about Captain Chestbeard that could change the course of the race. And Zomboss leaves detailed instructions for his minions at the lair.
Crazy Dave challenges Zomboss to a race between sun-powered, plant-drive speedsters and imp-powered, zombie-driven hot rods. The winner determines the future of Neighborville, while the loser can never return.
