The story of every set:

Set 1-The Beginning. Dr. Zomboss creates the Hero-Tron 5000, a device that turns anything it zaps into a "hero". He tests it on a zombie, and that zombie becomes Super Brainz. Zomboss celebrates his machine's success by putting his hands in the air, but in the process presses a forbidden button, and the Hero-Tron explodes, transforming 10 specific plants and 9 other zombies into "heroes", and the big battle ensues, with Crazy Dave commanding the plant heroes and Zomboss commanding the zombie heroes.

Set 2-Galactic Gardens. Zomboss sends an imp, a zombie, a conehead and a garg into space, where they come in contact with a passing comet called Meteor Z, which transforms the zombie, conehead and garg into brand new galactic zombies, while the imp becomes Huge-Gigantacus, who directs Meteor Z to Earth. The Plant-etary Guard, consisting of Beta-Carrotina, Ensign Uproot and Lieutennant Carrotron go to Earth to warn the other plant heroes of the threat, and they team up to stop it, while Huge-Gigantacus teams up with the other zombie heroes in an attempt to achieve victory.

Set 3-Colossal Fossils. Meteor Z has collided with Earth, and bore a massive tunnel into it's surface. Huge-Gigantacus explores the tunnel, with Beta-Carrotina in hot pursuit. At the end of the tunnel, they discover Hollow Earth, a world beneath ours where new primitive plants and zombies have evolved. Down here, the battle continues.

Set 4-Triassic Triumph. Neptuna becomes aware of the existence of Hollow Earth, and she floods it, invading with more newly evolved zombies. Aware of the invasion, the plants of Hollow Earth evolved to adjust to the change, and teamed up with the plant heroes to protect the land from the undead mistress of the sea. Their main task: Stop Neptuna from finding the Mustache Monuments, for the plants were aware that if Neptuna found them, she would be truly unstoppable.
