Internet artist Gergely Dudás is back to infuriate his fans with more mind-boggling puzzles.
Dudolf, as he is known to his fans, shared a new brainteaser on Facebook on Tuesday, asking users to find the frog among the leaves.
The busy scene features a mass of jungle plants in various shades of green and purple, making it extremely tricky to spot the amphibian lurking in their midst.
Over 2,000 fans have already attempted to find the frog – but can YOU spot him?

Eagle-eyed players should be able to spot the creature in the lower right hand side of the drawing – but you shouldn’t feel down-trodden if you can’t.
Many have described the puzzle as Dudolf’s ‘hardest yet’ in comments on Facebook, admitting it took them up to ten minutes to find the frog.
One fan wrote: ‘This was probably the hardest one for me, but I found him!’
Another agreed adding: ‘This one took me like 10 times longer than the others, the frog is so small, so well hidden! Kudos!’
The Hungarian cartoonist is behind some of the internet’s best-loved visual puzzles.
In May he challenged users to spot a single lollipop among dozens of ice creams.
With a sea of the frozen treats, all in very similar shades, it is almost impossible to spot the lolly.

Players should be able to spot the smiling lollipop towards the top right hand corner of the picture.
A number of people claimed they found the lollipop quickly but enjoyed the puzzle.
One person said: ‘Took 2 second to find the lollipop but spent 3mins laughing at the horrified 2 cones and the one licking them’
Another wrote: ‘The green ice-cream near the left top corner and with a big smiley face has caught my attention…I can’t take my eyes from it to spot the lollipop’

He also released a special Easter puzzle for fans.
Somewhere in this vibrant flower patch there is a single bee buzzing around for honey – but only the most eagle-eyed players will be able to pick it out.
Last year’s Easter offering, a single egg hidden in a busy garden, was challenging, but this one is undoubtedly more difficult.
For those looking for a clue, the yellow bee is flying between two blooms of the same colour.
Dozens of fans commented to say how tricky they had found the puzzle after Dudolf shared it on his Facebook page.

Another agreed: ‘I had to put my glasses on for this one ~ but I found it!’
Dudas became an online sensation after his deceptively difficult seek-and-find puzzle featuring a panda hidden among a group of snowmen swept the internet in December 2015.

He now produces puzzles for most major holidays – and delights followers by posting random editions throughout the year.
At Christmas Dudas released a new book, Bear’s Merry Book of Hidden Things, which uses colourful illustrations and seek-and-find puzzles to tell the story of a bear getting ready for a Christmas party.
While the title is aimed at children, the puzzles are tricky enough that they will keep parents entertained, too.
