Hungarian artist Dudás, who goes by the pseudonym Dudolf, is known online for his whimsical seek-and-find pictures. His illustrations consist of groups of cute cartoons, always with one out-of-place object blending into the crowd. In the past, he's hidden a sheep among a crowd of Santas for Christmas, a heart among snails for Valentine's Day, and an egg among a tulip field for Easter.

His brainteaser for Halloween is more of a trick than a treat. The image above is full of white skeletons, with just a handful of orange jack-o'-lanterns breaking up the monochromatic scene. Somewhere in the crowd, Dudolf has tucked away a white ghost. Test your observation skills by scanning the picture above for the hidden specter.
