Can YOU spot the fish hiding among the octopuses in this fiendishly tricky brainteaser?

FEELING groggy after the long weekend? You're certainly not the only one.

Well if you need something to kickstart your working week then we've got just the ticket.

Hungarian cartoonist Gergely Dudas - also known as - has left us totally stumped with yet another one of his fiendishly tricky brainteasers.

And if you thought picking the mouse among the mushrooms was bad, just wait until you try and find the fish lingering somewhere within this pack of octopuses.

Just to throw you off the scent, the clever cartoonist has added a few red herrings into the mix in the form of bows, shells, top hats and a treasure chest.

So how long will it take YOU to find the fish?

Found it yet? Well if you're anything like us, you probably gave up after mistaking the fifth bit of foliage for the fish.

But in our defence, that hidden fish was the EXACT same colour as his octopus friends.

And if that wasn't enough, he even had the same eyes as them too. Better luck next time, eh?
