A discarded silk top-hat becomes the focus of a struggle between a washed-up stage magician and a group of schoolchildren, after it magically brings a snowman to life. Realizing that newly-living Frosty will melt in spring unless he takes refuge in a colder climate, Frosty and Karen, a young girl who he befriends, stow away on a freight train headed for the north pole. Little do they know that the magician is following them, and he wants his hat back!
It's pure nostalgia again. It was on television almost every Christmas from 1969 to today. It was a Christmas tradition...
...and now unfortunately it's a tradition that is being copied by a thousand low-rent cartoons that even snatch the cover in their cheap imitations....
...but in any case, about two generations of American kids grew up with this as a part of their Christmas holiday, along with Rudolph and the puppet Santa cartoon. It's as much a part of Christmas as "It's a Wonderful Life" and "A Christmas Story," and it has spanned the generations.
Unfortunately it's on less and less now days and being replaced with, well, with NEW shows that don't have the generational love behind them.
