There's always a party at Christmastime, and there's one underneath the floor, where Mr. and Mrs Mouse celebrate in nook number twenty-four. 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 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 the child's birth on a day called Christmas. And so they decide that their family should celebrate Christmas too. Join the Mouse family as they discover the magic of their first Christmas, complete with their own mouse-sized tree, tiny cookie crumbs, and miniature stockings just waiting for Santa to fill with presents.
