Hungarian artist Gregerly Dudás probably chuckled fiendishly as he created his picture packed with snowmen and then tucked one unobtrusive and cleverly hidden panda in with the bunch.

Ever since he posted it on Facebook as a panda-pondering challenge, his followers have been hunting for the benighted bear, and the search has gone viral. Where is that flippin panda?! Now, 42,000 likes and 100,000 shares later, people are still searching the sea of snowmen and making comments like “Been looking for 15 mins, still can’t find it, lol.”

The puzzle has even spawned a spate of panda-deniers, such as the one who declared, “There ain’t no panda in there!” Dudás is becoming a master of mysterious drawings. He’s posted one with a sheep concealed among Santa Clauses and another with a heart hidden among snails for Valentine’s Day. On Halloween, the challenge was to find a polar bear stashed away in a crowd of ghosts.

As well as crouching snowmen, hidden panda, Dudás, who goes by Dudolf on Facebook, also does cartoons. My favorite is two children looking up at their cat in a tree and saying, “Oh, no, our cat is up there!” The cat in the tree looks down and says, “Oh, no, my humans are down there!” Bye the way, I did find the panda. It’s–no, I’m not telling!
