It's the Dogsled race up in Alaska and the betting line has him at 5,000 to one. That's worse than the penguin whose team consists of a single squeaky dog toy. That's probably because his team consists of Elmer the Great Dane, Oswald, however, is game, and Walter Lantz' staff probably thinks it's a good idea to use all the gags they left out of ALASKA six years earlier. And some they left in.
Paul terry's cartoon factory was in the habit of redoing cartoons every three or four years, having a different lead character, adding operetta music, sharpening up the backgrounding, adding color.... but basically the same cartoon. Walt Disney almost never did it, since his cartoons played forever. Lantz did it occasionally, and this is a case of it occurring. There's some switching around, some new gags, and the art style and even the way the characters are animated had changed. So it was fine to let the old version, which had fallen out of favor as hopelessly old fashion, lapse. No new prints for distributors! then produce this new one, and it was different enough and modern enough to satisfy the audience.
