Frosty the Snowman (special)

Plot
One December afternoon, a girl named Karen and her friends create a snowman after school. After several suggestions of what to call their snowman (including "Oatmeal" and "Christopher Columbus"), Karen decides to name him "Frosty". They later acquired a top hat discarded inept magician Professor Hinkle. When Karen places it on top of Frosty's head, the snowman comes to life (and always says "Happy Birthday" in response). When Hinkle learns of the magic power his hat actually possesses, he take it back and departs, pretending that he did not see Frosty come to life. However, the professor's pet rabbit Hocus Pocus returns the hat to Frosty.

Frosty soon senses the temperature is rising and worries about melting. The children suggest him on the next train to the North Pole
