S1·E51 Medusasaur

Haxx becomes the leader of the Raptors when he gets his claws on a mysterious mask that turns anyone who looks at it to stone, and uses it to turn Bad Rap into a statue! The Extreme Ones must find a way to put the mask out of commission before Haxx adds them to his statue collection, and they have to stop Haxx and Spittor from making off with a fossilized Velociraptor egg which they plan to clone into an army of Raptors!
