An illustration featuring a hidden panda has left thousands of people flummoxed as it sweeps social media.
Hungarian artist Gergely Dudás posted the Christmas puzzle on his Facebook page on 16 December, showing hundreds of hand-drawn snowmen with the single black and white bear hidden between them.
He told his 13,000 Facebook followers: 'There's a panda amongst them! Can you find it?'
The Where's Wally-style cartoon was liked by 42,000 people and shared 100,000 times within days, with many struggling to find the panda at all.
