Sesame Street characters hidden in rocks, but it does happen. That was the case for geologist Mike Bowers, who found a most peculiar discovery inside a rock picked up by his colleague Lucas Fassari in the Rio Grande dol region near Soledade in Brazil. Once split open, both sides of the stone just so happen to look exactly like the Cookie Monster.
