Continuity mistake: When Jingle, Jangle, and Mrs. Claus pay a visit to Mother Nature, Mother Nature calls her sons beside her - Snow Miser and Heat Miser. She then turns to Snow Miser and asks him to allow a little snow fall in the South, and then turns to his brother, Heat Miser, and asks to allow just "one Spring day at the North Pole." The words are correct dialog, but she should have said each of those lines to the OTHER brother. (00:39:40)
Continuity mistake: In the scene just before 'commercial break' in which Vixen is shown in the dog pound cage, at first she is shown wearing socks on her ears in dog disguise. Then there is a close up of her not wearing the socks, with her ears and antlers showing. When Santa comes to pick her up, she is wearing the socks again and the dog catcher is surprised to see that she is a reindeer when Santa removes them.
