A Redditor on /r/FindTheSniper took a photo in the woods, only to realize there was a lil' critter in the shot.
"Didn’t notice him when taking the photo of the lil lass," wrote u/filtha-delphia, referring to the deer that was captured in frame.
But the color of the deer is exactly the same as the trees, so it can be a little hard to see at first, but you should eventually see it.

If you're looking for an indoor challenge, try finding these camouflaged glasses.
