Playing with skeletons in a graveyard over Hallowe'en

When cheesescones came to visit Hampshire to do some caching, we went to get some older caches to help her fill her Jasmer table. One of the caches we did was in a graveyard and was one I'd already done so whilst she was locating the cache, rummaging through the swag and signing the log book, I stood waiting nearby. I stepped back to hear a crunch and looked down to see I had stepped on a skull! Not a human skull, but what I believe was a rabbit's. The more I looked around me, the more bits I found. Some legs, the jaw, the spine. Cheesescones managed to convince me not to take any of it home with me...
