"You see, it's like this Santa," the book reads. "I've adopted a polar bear named Leopold. He is in danger of losing his home. I'm sure you being in the North Pole you know about the melting glaciers. All I want this year Santa, is to save Leopold and his home."
Santa Claus visits the boy, takes him to see the polar bear and then in a moment of eco-awakening, he makes his operations at the North Pole green.
