i moved my out door toy box and saw a pile of poop all in the same place what is it?

Answer 1

Do you have pets?
Dogs and cats can be really picky about their toilets. Most of them pick the same place over and over.
OR
Do your neighbors have pets?
They could be cleaning their yard into yours.

Answer 2

C.H.U.D. (cannibalistic humanoid underground doberman)

Seriously, Could it have been there before the box was placed or did anyone move the box since it was placed there?

Did you see it as soon as you moved it or did you notice it a bit later. Dogs will sometimes seek fresh earth to leave the unwrapped gift.
