Haiku: Plants vs. Zombies

Plants Versus Zombies-
The title should tell you all
That you need to know.

Grow plants to survive
House is next to a graveyard
Mad doctor wants brain.

Many thanks to you
Bloom and Doom Seed Company
I love having brains.

Quoth the sunflower
There's a zombie on your lawn
You don't want it there.

Brains brains brains brains brains
Totally not a zombie
Brains, can't get enough.
