Vampire?

The vampire turned to her and grinned menacingly.
"My what a lovely neck you have my dear" he hissed.
Startled, she turned towards the vampire and gasped in apparent fear.
The vampire hissed and swooped in for the kill.
She screamed and attempted to duck out of the way.
The vampire had her in his grasp and went for the neck.
"JACOB!" the woman shouted.
"Take that costume off and get ready for school!".
"Awww Mom, you ruined it. I was going to turn you not eat you." Jacob said.
He ran upstairs with a harrumph.
She walked towards the kitchen, then paused.
She reached up to her neck and felt wetness.
Looking at her fingers she gasped at the sight of blood...

Snake!

The grass was very green today. I moved among the blades, enjoying the taste of the fresh air. The sky was blue and blessedly enemy free, at least for now. I slithered around a tree and came up short as I spotted a large creature. I had never encountered something like it before. It was very tall, and quite loud, making noises from its large wide mouth that I couldn't understand. Before I had the chance it turned around and spotted me. I tried to flee, but it reached down and caught me in it's large appendage. It took me up into the sky, higher than I could imagine and looked at me. I glared back menacingly and hissed. It made a strange throaty sound at me and carried me away. I coiled myself around it's appendage and squeezed with all of my might. I was carried towards another even larger beast with long fur on it's head. It turned around and shreaked in obvious fear. It must have noticed how terrifying I was. I hissed menacingly at it. The larger beast began making loud noises and pointing at the smaller one. Liquids began leaking from the smaller beasts eyes, and it finally put me down. Obviously my terrifying hiss and mighty squeezing of it's appendage forced it to leave me be and retreat in terror. I hissed once more at it for good measure and left at a leisurely pace, proving to the beast that I was a ferocious animal, not to be messed with.

The grass really was nice and green today...
