"Our story begins with Dr. Zomboss' latest plan of evil genius--disguising his zombies as each other, in an effort to confuse plants and plant pals Crazy Dave, Nate, and Patrice. Can the friendly fronds get past these dastardly disguises before the zombies sneak into Neighborville tourist attractions--and even Watson Elementary school--to unleash their hungry ways?"--Provided by publisher.
Zomboss plots to take over Halloween with his Lawn of Doom celebration, Crazy Dave perfects his turtle translator, and Patrice rescues Nate after he stumbles upon one of Zomboss's traps.
Zomboss continues to cheat his way through the second and third rounds of the tournament, Patrice and Crazy Dave devise a plan to help Nate reach the final round, and the factory owner makes a startling announcement after the winner is declared.
"Patrice and Nate grow suspicious when people start disappearing after 'Big Z's Adequately Amazing Flytrap Circus' arrives in Neighborville, but they must convince Uncle Dave to help them investigate"--Provided by publisher.
"The battle for the factory begins as plants and zombies compete in feats of strength, Crazy Dave overhears a forlorn factory owner wishing he could find the perfect ingredient to save his company, and Zomboss unleases an explosive badguette"--Provided by publisher.
Zomboss and Crazy Dave both want to buy the same factory at the center of Neighborville, but the owner proposes a battle extravagonzo to declare a winner.
When the evil Dr. Zomboss hears of the plants' plan to destroy the zombies he comes up with a plan of his own, a plan which the plants, Crazy Dave, and Nate and Patrice, must now try and counter.
