You never know what you're going to get when you crack open a geode-like rock called an agate, but a new specimen is even more surprising than usual: It looks just like Cookie Monster.
The agate, found in Soledade, a precious stone hotspot in southern Brazil, is a dead ringer for the blue, googly-eyed Sesame Street Muppet. After its owner, California mineral collector Mike Bowers, posted about the agate on Facebook, it went viral, with write-ups in newspapers from Australia to Israel to the United States.
"I didn't realize that Cookie Monster was so well known and part of the world cultural heritage!" Bowers told Live Science. He's since been contacted by the actor who plays Cookie Monster on "Sesame Street," he said. (Cookie Monster's official Twitter account also gave the agate a shout-out.)
