Answer:
I am clean when I’m black dirty when I’m white.
I plow and plow but never sow.
I have memories, but none of my own. Whatever's on my inside is what is shown. If I'm ever different, it's because you changed me. I feel like a decoration, here for you to arrange me. What am I?
I wiggle and cannot see; sometimes underground and sometimes on a tree. I really don't want to be on a hook and I become a person when combined with “book”.
What always ends everything?
Ripped from my ancestors home beaten and burned I become a bloodthirsty killer.
