Marvin the Yeti feels bored. It's the dead of winter and there is nothing for him to do. One day, he discovers a wooden statue of Santa Claus, buried in the snow. Marvin immediately thinks that he's found his calling-he must be Santa Claus! After all, he has a white beard (well, OK, he's covered in white fur, but same difference); he has a round little belly (well, OK, it's a rather large round belly, but even better!); his favorite color is red; and he lives near a whole flock of reindeer! Marvin's on a mission-to find a sleigh, to enlist the help of some elves (tundra creatures), and to set out on Christmas Eve to deliver presents worldwide.
