Every year as Halloween draws near, strange creatures and weird contraptions start appearing in everyone's lawns in Neighborville. A Neighborville Halloween is weird enough, but Zomboss and his zombie army want to turn the holiday into their own scarier Lawn of Doom celebration! With Zomboss filling everyone's yards with traps and special zombies, Crazy Dave, young genius Patrice, neighbourhood daredevil Nate, and a batch of brave, boisterous plants fight back in contests of best tricks, best treats, and best costumes!
