While Mrs. Claus may not be as well-known as her husband, she is nonetheless an important figure in the Christmas story. In addition to her traditional roles of overseeing the elves and caring for the reindeer, Mrs. Claus also plays a vital role in ensuring that Christmas is a success every year. Without Mrs. Claus, Santa would not be able to deliver presents on Christmas Eve or make sure that the elves are making enough toys.
