Little Zoo Sap and his family are moving from their summer home on the coast to the deep woods for the winter, traveling on a big bobsled pulled by big horses through the snow. When Zoo Sap falls off of the sled unnoticed, the forest animals hear his cries. First to come are the beaver, who put their tails together to cradle him. Then all the other animals circle round everyone from the tiny mouse to the giant moose to the great bald eagle keeping him warm and safe until his father comes back to find him.
