That had once been an orange. It had shrunk to about 1/4 it's original size. If it is from when I think it is, it rolled under there sometime in early winter. Because of the temperature it never had a chance to fully root and so it sort of half rotted half dried out. I threw it away. The smell has not immediately gone away but does seem to be fading after about a week.
