Technically speaking, it is a shell from a dreaded walnut left on my steps by a hungry squirrel.
According to Casey, this is "wind poop." He says it everyday and avoids it like it really is poop!
Last night when we got home from school and errands, Emily said, she had told Casey that the wind was a monster and it had "pooped" on our step and he'd better hurry and get inside before something else happened!!
