After a
newsreel highlighting children preparing for the arrival of Santa Claus is shown, a postman named Special Delivery "S.D." Kluger is introduced. When Kluger's
mail truck breaks down, he proceeds to tell the story of Santa in response to letters sent by children. A baby named Claus arrives on the doorstep of
Burgermeister Meisterburger, the grouchy mayor of Sombertown. Meisterburger orders Grimsley, his aide, to take Claus to the local
orphanage, but a gust of wind sweeps the baby away. Claus is rescued by a group of animals who transport him to the Kringles, a family of elves. They rename him Kris and raise him, teaching him how to make toys, the Kringles' family occupation. When Kris is old enough, he volunteers to travel to Sombertown and deliver the toys. On the way, he befriends a lost penguin whom he names Topper. Meanwhile, Meisterburger, having tripped over a toy duck, enacts a law prohibiting all toys. Kris then arrives in town and bestows toys on the local children, even giving one to Miss Jessica, their schoolteacher. Meisterburger orders Kris's arrest, prompting him to flee into the forest with Topper. They are soon captured by the Winter Warlock, but the Warlock befriends Kris after he is a given a toy train. To prevent further toy distribution, Meisterburger orders all doors and windows locked, but Kris enters by the
chimneys and places toys in the children's stockings. Meisterburger sets a trap for Kris, while his soldiers capture Winter and the Kringles. Jessica visits Winter in prison, where he reveals that he has lost all his magic except for some enchanted corn that enables some of Kris's
reindeer friends to fly. With the help of the reindeer, Kris and his companions escape. Meisterburger swears that he and his descendants will never stop hunting them down until they are captured again. Soon after, Kris, now sporting a beard as a disguise, returns to his "Claus" name and marries Jessica. They travel to the
North Pole to establish a toy workshop. After the Meisterburgers died off and fell out of power and their laws were abolished, Kris is
canonized as a saint, becoming Santa Claus. Due to the rising demand for toys, Santa limits his gift-giving to
Christmas Eve, the anniversary of his and Jessica's wedding. After finishing the story, S.D. Kluger suddenly remembers that he has to deliver the letters to Santa and leaves for the North Pole with Topper, Winter, and a parade of children, singing the title song. ==Voice cast==
