Trick or Treat

They would come in troops searching for me. I have to rush and clear soon.
I wore my gloves, laid the plastic and all the butchered parts on the bench. My MO was different. I started with the red-painted fingers that were oozing blood. Then legs, the vitals trickling till the toes and finally the torso, where I had thrust and tormented with the knife and sewed.
I assembled the parts on the pit. Placed the RIP tombstone, poured the rest of the red and covered it with mud.
Ding-Dong!

They came hungrily for the Halloween themed cake.
