Zombie Unicorn Attack

The walls closed in to my surprise.
I cried, tears in my hazel eyes.
The door blew open as my assassins came in covered in blood.
Their hooves were filled with mud.
"What the?!" I screamed.
"We're zombie unicorns!" they shrieked.
It was true!
Their decaying skin was blue.
They moaned as they came closer to me.
I looked around for an exit, I could not be free.
I kicked as they were about to eat my brain.
They jumped on me, the weight was too much of a strain.
Looks of hunger were in their eyes.
I know what they were thinking, "Brains. Tastier than any pies!"
As they kicked, my blood spurted all around.
Then my head fell with a thud onto the ground.
As my spirit descended, I saw them eat the contents of my head.
"YOU MORONS!" I yelled. I killed them all, and that's why the unicorns are said to be dead.
