But how long will it take for you to spot the bat in this first spooky image?
Vision care experts Lenstore have shared a Halloween-themed brain teaser for us to try out.
It features some cats, ghosts, witch hats and more… but requires you to find a BAT.
According to the creators of the puzzle, on average it takes 45 seconds to find it.
But how quickly can you do it?
If you managed to find the bat in less than 45 seconds then you're clearly an expert at this.
The creature was at the bottom of the image in between a ghost, a cauldron and a pumpkin.
This image full of pumpkins makes our brain go a bit funny.

It was definitely a hard one to find.
Another brainteaser by the same artist, whose real name is Gergely Dudas, features these tigers.

But how long will it take for you to figure out which one it is?
One poor tiger in the bottom right of the image was all alone, with no twin.
