When the Pteranodon family travels back to the North Pole, Don declares that it's his "winter wish" to see snow fall again. When a big blizzard comes, and even the Dinosaur Train gets snowed in, Don worries that his wish brought the blizzard. He's especially worried for his new friend, Soren Sauronitholestes, who is sitting on a nest of her eggs, out in the blizzard. But everything turns out all right: Dad explains that wishing for something doesn't make it happen, and the well-adapted, warm-blooded, feather-covered Soren successfully hatches her babies.While visiting the North Pole, the Conductor suggests that the family stop off at Aurora Borealis Station on an enormous frozen lake to see the Aurora Borealis, where the Northern Troodons celebrate a "Festival of Lights." While the kids wait for night to fall and view the Aurora Borealis, they work up an ice-skating show to entertain Mom and Dad. Everyone joins in to sing "Solstice Time is Here" and skate under the lights!
