Can't sleep, the clown will eat me.
It will haunt me in my sleep when I'm sleeping so deep.

I'll show you wounds that never heal,
To him I'm just a happy meal.

He's a tall guy, not so smart but he's shy.
He's made out of flesh and is stitched, his maker used him for revenge on the people in his town and Frankenstein couldn't say a word so he looked at them with a frown.
His cuts are so deep and got a tiny brain, killing the humans who's laughing at his maker is his main.
Frankenstein's bride is on his side, she's standing there with big brains and pride.
Every woman has a name especially when they're playing his game..

Five, six, grab your crucifix.
Seven, eight, gonna stay up late.
Nine, ten, never sleep again..

Grim Reaper:

Reaching out his hand with only bones as fingers, the demons are just the singers.
The grim reaper is just a cloaked skeleton, just run like the runners from a marathon.
'Can I make you an offer that you can't refuse?'
You're just out for me for the abuse.
'Your time is almost near, don't go further in fear.'
I really don't care..

.. And you:

You've got a ugly face, one of the simple minded race.
The morgue got a new place for someone, you've been killed by something what raiders call a gun.
It started many years ago, your mother and father sold Satan your soul.
You've been welcomed to the darkness with one single ray of light,
the gates of hell are open and something isn't right.
You've walked the stairs down to hell,
but even there is something that is new for you in hell..

Jason Voorhees:

He's 6 ft 8 tall, he's bigger than a wall.
The counselors are killed one by one, heading out for me but all the counselors are gone.
I'm the only survivor of this lake, why is he heading out for me for god's sake?

Thirty years later, Jason is back to avenge.
