Somewhere in this crowd of penguins, one of them is holding a chocolate cup. Your job is to find it before your eyes give up completely.
Most people scan the whole image once and see nothing but blue penguins. Then they look again. Still nothing. The colors blend together and every penguin looks exactly the same at first glance.
Stop looking at the faces. Start looking at the hands.
One penguin in the center of the image is quietly holding a small brown chocolate cup. It is easy to miss because your brain is too busy counting penguins.
Did you spot it on your own?
