Courage, Muriel, and Eustace are on vacation at the North Pole, the result of a misunderstood time-sharing deal. Courage goes out to get firewood and comes back to the igloo where they were staying and they are gone. Courage knew it was the snowman because he saw it earlier while gathering the firewood. He finds out that the snowman wants to extract the human "anti-melting gene" from Eustace and Muriel to be able to live in hot weather. Courage gets captured by the snowman but escapes and saves both. The snowman falls into icy water while chasing them and freezes into a giant ice cube. Muriel, Courage and Eustace then go home.
