You have 20/20 vision if you can spot the kid-size Crocs disguised among the rocks in under 30 seconds

A MIND-BOGGLING brainteaser could be a sign of extraordinary vision — but only if you can find the child’s missing shoe in time.

Anyone can see the endless piles of stones, but a sharper eye is necessary to spot the Crocs in this optical illusion in less than 30 seconds.

Reddit

Redditor Centerwook posted a picture of the missing Crocs.

They asked others to help find their child’s shoes, which were lost among the rocks.

Although the Crocs are hiding in plain sight, they’re tricky to spot in under 30 seconds.

At first glance, the photo appears to be nothing more than a rock-covered trail surrounded by leafy green trees.

There are plenty of nooks and crannies for the shoes to disappear into, making the task of finding them even more difficult.

Several Redditors took a stab at finding the missing footwear.

“I’m still lost. All I see are rocks, and no Crocs,” one wrote.

“Sorry kid, can’t find them. You’re walking home barefoot. No whining now, you shouldn’t have lost them,” another joked.

“Fellas this is why you should always buy your Crocs in unattractive neon colors,” said a third.

If you’re still having trouble finding the lost footwear, start at the bottom of the photo.

Shift your eyes to the center and move them up until you spot the shoes.

Redditors rejoiced at finally finding the lost footwear after searching high and low.

“Wow this was a good one,” one said.

CREEPY CRAWLY

If one wasn’t enough, there’s another brainteaser for puzzle lovers to solve.

This one could get dangerous if you don’t spot the hidden rattlesnake in under 18 seconds.

Everyone can see the leaves and sticks, but finding the critter is a lot tougher.

With a bite that could end in a fatality, this one is not just about finding the serpent, but finding it fast.

Several Redditors worried that they couldn’t spot the snake in time.

“Yes, I’m dead. Where do you live so I don’t come visit?” one wrote.

Another suggested keeping the venomous creature alive.

“That’s a big boy there. Not sure where you’re at but hopefully you didn’t kill it since we actually need these to control the little critters running around the woods,” they said.

If you’re still stumped, focus on the middle of the photo towards the top.
