A mind-boggling optical illusion has tested the eyesight of internet users. Can you solve it?
This optical illusion, featuring a hidden hippo in not-so-plain sight among the rhinos, has gone viral, and it takes a real keen eye to spot it.
The viral post, shared by X user Piyush Tiwari, requires the sharpest observers to spot the single hidden hippo amid the crash of rhinos.
The challenge is to spot the hippo in just seven seconds.
The tweet boldly claims: ‘Optical Illusion Vision Test: People with excellent observation skills can spot a hippo hiding among the rhinos in 7 seconds. Can you? Attempt now!’
So, set a timer for seven seconds, scan the image carefully and look for the hidden hippo.
At first, the image seems like a slightly bizarre scene of rhinos grazing by sliced watermelons (with some of the creatures wearing sunglasses) but don’t be fooled.
The sneaky hippo is camouflaged, blending in with the other mammals.
