Synopsis

As Annie and her Tyrannosaurus rex herd began their seasonal journey in search of sustenance, the young Pteranodons watched with curiosity. They wondered if other creatures, even those of the sea, followed similar paths. The Conductor guided the Pteranodon family aloft in the Dinosaur Train Zeppelin, soaring over the ocean in pursuit of Polycotylus, a marine reptile known to undertake migrations. From the air, they spotted a pod of migrating Polycotylus and descended the Zeppelin onto an atoll.
