I, Zombie

I, Zombie is a group of Puzzle Mode levels where the player must plant zombies to overcome cardboard plants and get to the end of each row, where there is a brain that the zombies must eat. The level is over when all of the brains have been eaten.

Overview
At the beginning of the first level, Crazy Dave tells the player that the zombies want practice invading houses, and as he didn't want any plants harmed he put cardboard plants on your lawn. It is the belief of some players that Crazy Dave made the plants come to life with his Magic Taco.

Strategy
I, Zombie is a very strategic puzzle game. First you must find ways of getting sun, whether it is using Bungee Zombies to take them, Gargantuars to smash them, or noramal zombies to eat them. Also, the player must have a pretty good idea of each zombie's abilities. For example, if a row has a few cardboard Peashooters, it is safe to safe that planting a Buckethead Zombie or a Football Zombie will earn you a brain and further you to beating the level. After every three levels of I, Zombie Endless, a Present, Chocolate, a money bag with gold coins or a money bag with a diamond usually drops, although it will not always happen.
