(As the Grinch's sleigh flies over Whoville, he spies a curious sight: Frosty the Snowman, dressed in a red and green outfit and singing Christmas carols. The Grinch's heart grows three sizes as he realizes that Frosty is bringing joy to the children of Whoville. The Grinch lands his sleigh and approaches Frosty, who turns to face him. The Grinch extends his hand in friendship.)
