Calvin as a dinosaur: Calvin is coming! The late Cretaceous: The last epoch of the mighty dinosaurs! King of the thunder lizards is the fearsome Calvin, the Tyrannosaurus! Seven tons of muscle and teeth. He searches for prey! Mom: Calvin, for goodness sake, stop stomping around! You're driving me crazy! OW!! Chomp!! Calvin: How did the fearsome Tyrannosaurus become extinct? Now we know! Dinosaurs everywhere flee for their lives!
