The story of "How the Grinch Stole Christmas" is about a grouchy creature called the Grinch who lives on Mount Crumpit above the town of Whoville. The Whos in Whoville love Christmas and celebrate it joyfully every year, which annoys the Grinch deeply. Determined to stop Christmas from coming, the Grinch disguises himself as Santa Claus and sneaks into Whoville on Christmas Eve. He steals all the Christmas decorations, presents, food, and even the Christmas trees from the homes of the Whos. However, as the Grinch is about to dump all the stolen items off the mountain, he hears the Whos singing joyfully despite their losses. He realizes that Christmas is about more than just material things—it is about community, kindness, and love. This realization makes his heart grow three sizes. The Grinch then returns everything he stole and joins the Whos for their Christmas celebration, carving the roast beast at the feast himself. The story conveys a message about the true spirit of Christmas being beyond gifts and decorations.
