Puzzle Mode

Puzzle Mode is a Mode of the game that contains two separate puzzle types.

Vasebreaker
In this puzzle, you have break open all the vases and defeat the zombies hidden inside. Different Vasebreaker levels have different plants and zombies, but there are some features common to most of them. Most contain Leftwards-Facing Repeaters, and all after "To The Left" have two green plant-containing vases with leaf symbols on them. Also, Planterns in "Ace of Vase" and "Vasebreaker Endless" show the contents of the vases adjacent to them.

I, Zombie
I, Zombie, its name a reference to the book I, Robot, is a group of levels where you must plant zombies to overcome cardboard plants and to get to the end of each row, where there is a brain. The level is over when all of the brains have been eaten. At the beginning of the first level, Crazy Dave tells you 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.
