Jimmy Durante narrates this Christmas story that is based on the song of the same name. To make up for the fact that her students are in school on Christmas Eve, the local schoolteacher hires the magician Professor Hinkle to entertain the kids. Unfortunately, he's not a very good magician. Frustrated in his attempt to pull a rabbit out of his hat, he throws it away in anger. Outside, the kids build a snowman (what to call it? Harold? Oatmeal? Frosty!), and when the hat blows onto it--Happy Birthday!--it comes to life. Professor Hinkle decides he wants the hat back so he can make money off of its newfound magical properties, but the kids want to save Frosty. When the temperature starts to rise, a new problem threatens Frosty's existence. Karen, the leader of the children, comes up with a plan to save him: take him on a train to the North Pole, where it's always cold. With a cameo by Santa Claus, and the promise of Frosty's return every year, this story of life, death, and holiday cheer is glazed with the sweet frosting of hope and happiness. A true holiday classic.
