Take a look at the Reddit post above. At first glance, it might look like a green leafy plant sitting in a pot full of grey stones. But there is something else hidden in the image, and it's your job to find it.

Somewhere among the leaves and stones is a frog. You'll need eyes like a hawk to be able to spot the small amphibian, but it is there somewhere if you're able to focus and study every pixel of the image.

If you manage to find the frog within 20 seconds, you may actually be able to consider yourself a genius. The time limit is pretty tight, so don't worry too much if you're not able to find the frog that quickly.

Practice makes perfect with these brainteasers, so take this one at your own pace and you might find you start to get faster the more puzzles you try.

Have you found it yet? If you're struggling, here's a hint: The frog is on the plant, so you can forget about looking at any of the rocks. You're also looking for a green frog, so there's no need to analyse any brown spots to see if they have legs.

We're going to give you the answer just below this, so don't scroll any further if you're still looking!

Answer

The frog is right in the middle of the green plant. The amphibian is incredibly small, so you won't be able to see it without zooming in, but we promise it's there!

If you look at the leaf in the centre that's curled around into a tube shape, a very small frog's head can be seen poking up from the very bottom of that leaf. It looks like the frog might be tucked into the leaf itself, so you can only really see its head, making it incredibly difficult to spot.
