Narrated by Fallon, the colorful special focuses on a boy who has his meticulous, detailed plan leading up to Christmas upended upon the arrival of some unexpected guests at the home he shares with his mother and dog, Gary. From finding the best tree, to perfecting his snow sled, to making scrumptious Christmas cookies, everything goes topsy-turvy as Christmas morning draws near. But, despite all the changes, the true spirit of Christmas manages to shine through in this 30-minute special for the whole family.
