Courage the Cowardly Dog - Season 1 Episode 19
The Snowman Cometh

Courage, Muriel and Eustace go on vacation to the North Pole. Courage goes out to get firewood and comes back to the igloo (where they were staying) and finds everybody else is gone. Courage knew it was a snowman because he saw it earlier. He figured out that the snowman was taking a liquid from Eustace and Muriels body to be able to live in hot weather and not melt. Courage gets captured by the snowman but breaks out and saves both. The snowman falls into icy water while chasing them and freezes into a giant ice cube. Muriel, Courage and Eustace go home.
