IF you can spot the mouse in this tricky optical illusion within 20 seconds you may be able to call yourself a record holder.
The mindboggling puzzle, designed by Hungarian artist Gergely Dudás, shows the creature hiding among a field of mushrooms.
The mushrooms are in all different shapes and sizes, making it fiendishly difficult to spot the critter.
Viewers have been left stumped as they scan the illusion trying to find the mouse.
Speedy viewers that spotted the mouse within 20 seconds may be able to call themselves record holders.
But, one person claimed online that they instantly found the mouse, spotting it after just two seconds.
While others tweeted to say that they found the mouse between 30 seconds to a minute.
Viewers that are struggling to find the critter should cast their attention to the left-hand side of the puzzle.
After scanning up and down the image, you should be able to see the creature peeping above the large mushroom that has an orange head.
The mouse is extremely difficult to spot as you can only see its ears and face.
