Santa and the Three Bears (1970)

In this animated movie, two bear cubs that are being raised by their mother discover the story of Santa Claus when they hear it from a park ranger. The curious little bears become determined to meet Santa, a goal that doesn't fit in very well with their mom's winter hibernation plans. As the three bears try to settle down for their cold-weather slumber, the restlessness of the cubs makes sleep impossible, and they remain determined to see jolly old Saint Nicholas.
