Santa's Littlest Helper is always first to finish wrapping his presents and packing his sleigh, and the other helpers tease him. But when Christmas Eve arrives and they are all struck down with Christmas pox, it's the littlest helper who comes up with a plan to save Christmas. While the bigger helpers deliver to human children, the littlest helper delivers presents to the animals, and he enlists their help to ride the sleighs and visit all the cities and villages in time for Christmas morning.
