Drew Barrymore stars as the voice of Olive, the dog that thinks she's a reindeer in the Emmy-nominated animated holiday special OLIVE, THE OTHER REINDEER, which makes its Cartoon Network debut on December 14, at 8:00 pm. The animation is based on the illustrations of J. Otto Siebold, who co-authored the titular book with Vivian Walsh. In other reindeer news, Cartoon Network will also screen GRANDMA GOT RUNOVER BY A REINDEER for the first time on that network on December 16 at 8:00 pm. Expanding on the holiday story from the song of the same name, GRANDMA GOT RUN OVER BY A REINDEER finds Grandma and her little general store in danger of being bought out by developers in the town of Cityville. While Grandma tries to save her store, her grandson Jake attempts to save his belief in Santa Claus and the Christmas spirit. In addition to these "endeering" holiday specials, Cartoon Network is offering up a 24-HOUR CHRISTMAS PARTY beginning Tuesday, December 24, at 12:00 pm and running until noon on Wednesday, December 25. The marathon will unwrap holiday feature films, classic Christmas shorts from animation's golden age and special shows starring cartoon luminaries including Scooby Doo, Pac-Man and Space Ghost.
