Over the snow, the world is hushed and white, but under the snow is a secret world of squirrels and snowshoe hares, bears and bullfrogs, and many others who live outside in the woods during the winter.
Every autumn a bear shows up behind the farm, and goes through a series of routines before finding a den among the hilltop boulders where he sleeps all winter long.
Curious George learns about hibernation and decides to try sleeping through the cold winter months, just like a bear, and after he gets only one night of sleep, he wonders if he can have fun throughout the season.
