King George, unlike most kings, spends most of his time in the bathtub, playing with his favorite toy - a rubber ducky. But George isn't satisfied with just his rubber ducky - he wants all the duckies! The king learns a lesson in humility from his brave soldier Thomas, whose ducky George had stolen. Eventually, George faces his sin and learns that it's always important to share with others.
