The resident mouse Gumdrop , while admiring the house all decorated for Christmas, noticed Timmy's letter to Santa on the floor. The letter must of have fallen off the table and never got mailed. So he and the family dog Gobber set outside to deliver the letter to Santa and save Christmas for Timmy.
