Our Pteranodon family is on the beach watching small eggs hatch and baby Archelon turtles emerge, and start to swim away. Our family and Mr. Conductor get into the Dinosaur Train Submarine and follow the baby Archelons who discover their own facts of nature - that their mother doesn't stay with them after they're born, and that they will grow up to be giant-sized sea turtles.
