Dead Things on A Work Break

I was sitting on a bench reading a book in the sun when I noticed something strange about the little pile of brown sticks and moss a few inches from my feet. Upon closer inspection, I noticed that it was a decayed rat with little toes and a long brown branch-looking thing that must've been it's tail. Everything was brown except for the toes, which were still white. The whole thing was pretty much decayed though, which is why it looked like a pile of branches and moss. It was disgusting, but fascinating. I don't know how it got there either. I know it wasn't there this morning, when I took my earlier break. Maybe it fell out of someone's backpack...
