To combat Zomboss' smoke-spewing machine, which is blocking out the sun, Nate and Patrice transform their bicycles into botanical battleships.

A group of young plants move out of Crazy Dave's garage and into his huge family mansion in Neighborville, but Dr. Zomboss is spying on them and trying to find out secrets to convey to his zombie army.

"Dr. Zomboss creates an army of teeny zombies to try and sneak up on all the brains in Neighborville! To battle these miniscule menaces, the plants, Crazy Dave, Patrice, and Nate must shrink themselves to have any chance at defeating the zombies. But how will Neighborville's insects react to the invasion of their turf-of-the-tiny? And will this miniature zombie invasion mean the party for Crazy Dave's two-hundred-year-old pants gets cancelled?"--Back...

"Zomboss hopes to hypnotize humans, using their dreams, into liking and approaching zombies instead of fearing them and running away."--

Evil mastermind Zomboss wants to build a zombie factory and position his new army in the best location possible, but Crazy Dave, his helpers Nate and Patrice, and their batch of intelligent plants, will try to get the factory for themselves.

As the battle for Neighborville continues, Patrice comes face-to-face with a zombie yeti and Nate comes up against gargantuars.

Using his newfound knowledge of humanity, Zomboss launces a strike against the heart of Neighborville, sparking a series of zombie-versus-plant quarrels.

Crazy Dave helps his niece, Patrice, and Nate Timely, and their plants travel back and forth in time to defeat the evil Dr. Zomboss and his army of zombies.

A new team of zombies team up to take down Zomboss and destroy Neighborville themselves, but Patrice and Nate are all set to defend their hometown.

In a race against time Patrice, Nate, and Crazy Dave travel to the time of the dinosaurs to stop Zomboss from collecting the parts he needs to complete the deadly sun vacuum.
