Do you see it?
According to the image creators, Book an Eye Test, the puzzle takes an average of one minute and 13 seconds to solve.
But one eagle-eyed player managed to find the unique fox among its flurry friends in just 25 seconds.
If you are struggling to solve this brainteaser, look to your left.

The fox is surrounded by other animals – including a horse, lamb, and a now-extinct passenger pigeon.
A sheep can also be seen nestling at the base of the tree, while a boar is lurking in the undergrowth.
