Help with "Paparazzi" Parody lyrics?

Hi! Okay, so I'm currently working on a parody of the song "Paparazzi" by Lady GaGa, it's called "Zombie-Razzi" So I think you can guess the topic. But anyways, there are some of the lines where I am just completely stuck at what could go there, and other's that are okay lyrics, but they could definitely do with some improvement and I'm just having trouble figuring out how to go about doing that. So anyways, here's the lyrics. The stuff in parentheses is the original lyrics, and I put an asterick next to all the stuff that needs a line for the parody verion and I out two next to the lines that I'm not quite satisfied with.

Here come the dead (We are the crowd)
They’re stu-stumblin down (We’re c-coming out)
Got a shuffling step (Got my flash on it’s true)
And a frightening moan (need that picture of you)
They’re so hungry now (It’s so magical)
They just want to eat your brains (We’d be so fantastical)

Chainsaws and guns (Leather and jeans)
Only work for so long (your watch glamorous)
**Except that the noise (not sure what it means)
**Will bring zombies to you (but this photo of us)
**So why don’t you try (it don’t have a price)
**Using something quieter (ready for those flashing lights)
*(‘Cause you know that baby I)

You’re their main course meal (I’m your biggest fan)
They’ll follow you until they eat you (I’ll follow you until you love me)
Zombie-zombie-razzi (papa-paparazzi)
*(Baby there’s no other superstar)
*(You know that I’ll be your)
*(papa-paparazzi)

Zombies are real slow (Promise I’ll be kind)
But they wont stop until they’ve had their fill (But I won’t stop until that boy is mine)
Honey you’re their lunch they’ll (Baby you’ll be famous)
Chase you down until they eat you (Chase you down until you love me)
Zombie-zombie-razzi (papa-paparazzi)

**Now it’s time for (I’ll be your girl)
**Use to get us some swords (Backstage at the show)
**And to brush up on (yeah cause you’ll know)
**All our awesome ninja skills (I’m staring between the sets)
**To help us with the kill (Eyeliner and cigarettes)

I can still hear their moan (Shadow is burnt)
At all hours of morn (Yellow dance and return)
But zombies don’t sleep (my lashes are dry)
And now neither do we (With the teardrops I cry)
How I wish that I (It don’t have a price)
Had thought of bringing earplugs (loving you is cherry pie)
*(‘Cause you know that baby I)

You’re their main course meal (I’m your biggest fan)
They’ll follow you until they eat you (I’ll follow you until you love me)
Zombie-zombie-razzi (papa-paparazzi)
*(Baby there’s no other superstar)
*(You know that I’ll be your)
*(Papa-Paparazzi)

Zombies are real slow (Promise I’ll be kind)
But they wont stop until they’ve had their fill (But I won’t stop until that boy is mine)
Honey you’re their lunch they’ll (Baby you’ll be famous)
Chase you down until they eat you (Chase you down until you love me)
Zombie-zombie-razzi (papa-paparazzi)

Real bad (Real good)
They’ve got your house surrounded (we dance in the studio)
Bang, bang (snap, snapped)
They’ve gotten through your front door (that s*** on the radio)

Don’t stop, for anyone (Don’t stop boy, rewind)
The zombies are coming and it’s time to RUN (We’ll blast it but we’ll still have fun)

You’re their main course meal (I’m your biggest fan)
They’ll follow you until they eat you (I’ll follow you until you love me)
Zombie-zombie-razzi (papa-paparazzi)
*(Baby there’s no other superstar)
*(You know that I’ll be your)
*(Papa-Paparazzi)

Zombies are real slow (Promise I’ll be kind)
But they wont stop until they’ve had their fill (But I won’t stop until that boy is mine)
Honey you’re their lunch they’ll (Baby you’ll be famous)
Chase you down until they eat you (Chase you down until you love me)
Zombie-zombie-razzi (papa-paparazzi)

So if you could give me some feedback on the lyrics, and ideas on what to fill the blank spaces or how to improve parts of it. If you don't like my lyrics then please just silently exit the page without wasting everybody's time on a rant of how I suck, because it's really not nice. I'm looking for constructive criticism and brainstorming, not plain old criticism. So thanks everybody and anything helps!
The stuff with asteriks is what I need help with. Sorry if that wasn't quite made clear, I re-read my question and realized that my spelling died when I was writing that sentence.
