Dr. Zomboss is back with another set of nefarious plans to defeat the pesky plants and Neighborville's resident adventurers Nate and Patrice! When Zomboss sets his sights on destroying the yards in town and rendering the plants homeless without anywhere to grow, it's up to the daring duo, along with Crazy Dave and his band of plants, to thwart his plans and claim victory once again! However, it turns out that those plans include dogs, cats, rabbits, hammock sloths, and even more pets, plus dinosaurs, making things a lot zanier.
