A viral image posted to Reddit is putting viewers’ eyes to the test—and it’s not as easy as it looks. The deceptively peaceful forest stream scene holds a hidden reptile that’s proving nearly impossible for many to find: a perfectly camouflaged snake.

Optical illusions have always held a unique grip on the internet, blurring the lines between what we see and what’s actually there. The latest brain teaser, shared by Reddit user @lumpybuddha, fits that bill perfectly. At first glance, it seems like a tranquil moment captured in the woods—glistening water gently flowing through a rocky creek, shaded by towering trees and lush greenery. But somewhere in the image is a snake that’s almost invisible to the naked eye.

Now that you’ve been told there’s a snake in the picture, you might assume it’s a quick spot. But for thousands who’ve tried, the task is surprisingly tough. The reptile is so expertly blended into the stony terrain that even seasoned illusion-hunters are left baffled.
