Spaceman Discovers Christmas #1

J.B. Grook, a good-natured, but somewhat bumbling and forgetful Martian, lands his flying saucer before two astonished kids, Tommy and Susie Ryan. It seems that the folks on Mars wish to add another holiday to their calendar, and have sent Grook to Earth for some ideas. Tommy and Susie show him the various aspects of Christmas, convincing Grook to take the spirit of Christmas with him back to Mars.
