Instead of the lyric, ``All of the other reindeer,'' Olive the pup hears something else on the radio: ``Olive, the other reindeer.'' She concludes that she is to be Santa's canine helper, so heads up to the North Pole, to join the Christmas Eve flight. Dangling from a ribbon tied to Comet's reins, Olive looks more like a stray ornament than a reindeer, but her doggy talents of chewing, sniffing, and fetching rescue Father Christmas from multiple mishaps. The story is as slight as they come, but the art sings a song all its own. Seibold's gregarious cartoons create an avocado-and-tomato colored cartoon Christmas in which little details shine: In a scene of flutes falling out of the sky and into a snow bank, a cutaway shows a surprised bunny awaking to find its burrow pierced by a silver shaft. Children will like the sophisticated art, even without a tight storyline. (Picture book. 4-8)
