Night Prompt Attempt

Here's my attempt at: In the middle of the night, I heard ___________ outside.
My first thought was to do something paranormal, but I stared at a children’s book, and got another fun idea. Here’s my attempt:
 
In the middle of the night, I heard a rasping sound outside. I immediately pulled my covers over my head to block it, but it didn’t work. My heart pounded with each terrible rhythm against the wall; there was no controlling it. The shadows from the moonlight didn't help, either. Gulping, I mustered enough courage to check the origin of the rasp.
I threw my covers on the floor and slipped on my shoes. When I had them on, the sound got louder. I was amazed that no member of my family had woken from its clobbering, but there was no time to find out whether they had.
I slid the window up and crawled out. I stubbed my finger with the rocks beneath and came face to face with IT! 
Its eyes were large, brown bottle caps. 
Its nose, wet with goo protruding out one nostril. 
Its sharp, long teeth were white like a crescent moon. 
Its wooly fur was messy. 
Its breath was grueling, like onions mixed with ice cream. 
I almost fainted. 
And you know what that thing did? 
It licked my cheek and jumped on me!
