In the run-up to Halloween, the CIA has tweeted a spooky scene and asked eagle-eyed followers to see if they can spot the difference.
'Can you spot the disguised differences?' the spy agency tweeted together with a pair of typical Halloween images that includes everything from graveyards and pumpkins to bats and broomsticks.
Twitterusers then took it upon themselves to solve the timely puzzle with some retweeting the images with some noticing up to 13 differences between the pair of pictures.
