Before the Grinch can push the sack of stolen gifts off the top of Mount Crumpit, he hears the Whos singing and realizes that he has failed to prevent Christmas, but then has an epiphany and finally realizes the true meaning of Christmas, causing his heart to grow three sizes. The sleigh full of gifts then begins to slide over the edge of the cliff along with Cindy, who had come to spend Christmas with him. The Grinch gets the strength to lift the loaded sleigh and carry Cindy to safety, and they ride down the mountain to return everything.
