There's nothing that marks the holiday season quite as well as a baffling festive brainteaser.

So, of course, we've found two colourful puzzles that'll leave you scratching your heads this Christmas. But, don't worry, we've also circled the answers in case you get stumped. The first of the mind-melting images has a tiny Brussels sprout hidden among Santa's helpers. Can you track it down? Scroll down if you want to see the answer...             .....are you sure?             Okay, don't say we didn't warn you. The teeny-tiny sprout is located on the third row of elves from the bottom, on the shoulder of the second elf from the left. The pictorial head scratcher was created by Clarendon Serviced Apartments in London as a holiday guessing game. And they've got another few in store, if you're up for trying them. The photo below may look like a a bunch of Grinches, but a mischievous and mini Yoda is hidden among them. You'll have to look carefully though - he's tricky to spot. You'll have to be eagle-eyed if you want to catch the tiny Star Wars character - or just check below. We've tracked down Yoda hidden among the Grinches, and have the solution circled further down. So just keep scrolling fi you want to find out the answer...       ....are you sure?       ....positive?         Okay.... Check out the hat of the second Grinch face in the bottom row - and the third Santa hat overall.
