Continuity: When Mrs. Claus first visits Snow Miser, he refers to Heat Miser as his "step-brother" but if they are both Mother Nature's sons, he would be his half-brother.

Continuity: 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.
