When Mr. Mouse and his family move into the warm spot beneath the kitchen stove in a big house, they discover something new and wonderful: an evergreen tree decorated with lights, ginger and peppermint smells in the air, and cookies baking in the oven. They hear about a child born long ago, and a jolly man named Santa who brings gifts to celebrate Jesus s birth on a day called Christmas. And so Mr. and Mrs. Mouse decide that their family should celebrate Christmas too.
