What's the name of this animated Christmas film?
Does anyone know the short animated Christmas film about a bunch of circus animals (including a kangaroo & a lion) traveling on a train when the train losses control and somehow crashes, freeing the animals into the winter night? Later on in the film there are Santa's deer that are also separated from the other deer as well as Santa himself. There are also wolves that are supposed to be the "bad guys". The film ends with Santa interrupting a showdown between the wolves and the deer and circus animals. WHAT'S THE NAME OF THIS FILM PLEASE!!!
