The Paw Patrol is on a big excavation dig in the jungle with Cap'n Turbot looking for dinosaur fossils when they unearth 3 fossilized eggs. Before they know what's happening the eggs start to hatch and there are three baby pterodactyls running around Adventure Bay! It's all paws on board for this rescue as Ryder sends the pups to catch the dinos. Just as they're doing that Mayor Goodway and Mr. Porter call to report a Utahraptor is destroying Mr. Porters restaurant, and eating everything in sight! And as soon as they get this news, another call comes in, there's a Triceratop on the railway tracks!! Paw Patrol is on a Roll. Rubble befriends and coaxes the baby Triceratop off the tracks and even gets that dino to help rescue one of the baby pterodactyls. As Chase, Skye and Marshall collect the other two hatchlings, Rocky rigs his peanut dispenser to deploy liver sausages luring the hungry Utahraptor home to the jungle. Soon all the prehistoric creatures are back where they should be, just in time for Rubble to wake from his most vivid dream ever.
