Plants VS Zombies Garden Warfare

Have you ever wondered how the war between plants and zombies started?!
Here's how it goes.
David's wife Kelly was brain-napped by zombies. And instead of smacking the zombies with a pot, David hit himself. He went..... CRAZY!!! And put the pot on his head. From that day forth we was known as Crazy Dave. He mutated a Pea Pod, a Sunflower, a Venus Flytrap and a Catcus for protection. But Dr. Zomboss predicted everything he armed his best, fattest, smartest and tallest zombies with guns and gave the cool abilities and awesome names. It was the Lawn of a New Era. It was.......... GARDEN WARFARE!
