Plants VS Zombies: What's going on?

Neta Peleg, Fanfic writer, office worker, and video game player extraodinair.
Tragically passes away.
For like a year or two, at least.
What happens next?
BOOM! Zombie Apocalypse!
"What the hell is going on?"

Now as a Zombie, Neta, seeing as everybody else is dead and brainless, joins forces with the smartest Zombie unAlive~ Dr. Zomboss.

Now if only that crazy bearded guy could stop creating zombie-killing plants, that would make this second stint on Earth a lot easier.
