The day after Christmas Santa and the elves begin making toys for next year's holiday. The first toy they finish is a pika which they name Percy. He sits in a special place and watches as Santa and the elves create other goodies. When Christmas arrives, the elves load Santa’s sleigh, placing Percy Pika right on top.
Meanwhile near the North Pole scientist Bob Nelson, his wife Susan, and son Jimmy are moving to a new workstation. They start out early hoping to arrive before dark on Christmas Eve. Difficulties cause them to lose their way but soon they see a house lit with holiday lights. They knock on the door and are greeted by a pleasant woman who invites them in to warm up and enjoy some nourishment. She offers to let them spend the night and continue their journey safely the next day.
Jimmy is afraid Santa won't find him when he's not in his new home. But Jimmy is in for a wonderful surprise.
