Hungarian artist Gergely Dudás creates mind-boggling brainteasers, often containing hidden objects or details, and challenges the internet to find them. In past drawings, he’s hidden a mouse among mushrooms, a penguin among toucans, and a heart among flowers.

He’s also released three books of brainteasers: one of holiday puzzles called “Bear’s Merry Book of Hidden Things,” a Halloween-themed book called “Bear’s Spooky Book of Hidden Things,” and his latest, “Bear’s Springtime Book of Hidden Things.”

In his latest illustration, Dudás drew 12 pairs of rabbits with matching patterns on their ears, faces, and bellies — but one rabbit doesn’t have a twin. Can you find the odd one out?

Take a look at the brainteaser below.
