Can you find the fish at the bottom of the ocean? That’s what Gergely "Dudolf" Dudás, the Hungarian artist who has regularly delighted our eyes and teased our brains by hiding everyday objects in elaborate illustrations, wants to know. The man who turned a panda hiding in a group of snowmen into a viral sensation is back at it again, this time with a more summer-appropriate landscape: the ocean.

Concentrate and see how long it takes you to find the fish in this marine life-filled illustration. (Give up? You can find the solution here.)
