I have been hooked up with it recently, too. Haha, yeah. And what I like is that after I finished all the levels and stages I get to enjoy a very cute music video of the game's theme song "There's a Zombie on your Lawn".
Let's me share to you this Youtube clip and Lyrics of Plants vs. Zombies Theme Song. Enjoy! :D
There’s a zombie on your lawn
There’s a zombie on your lawn
There’s a zombie on your lawn
We don’t want zombies on the lawn
I know your type: tall, dark, and dead
You want to bite all the petals off of my head
And then eat the brains of
the one who planted me here
I’m just a sunflower but see
me power an entire infantry
You like the taste of brains
we don’t like zombies
I used to play football
Road cones protect my head
I have a screen-door shield
We are the undead
Maybe it’s time to reevaluate
I know you have a lot of food on your plate
Brains are quite rich in cholesterol
You’re dead so it doesn’t matter,
Instead we’ll use this solar power
to make a lawn defense at any hour
I like the tricycle
There’s butter on my head
I’m gonna eat your brains
