I know that story! It's a classic! The Grinch is a grumpy and gruff creature who lives in a cave on the side of a mountain. He hates Christmas and all the joy and cheer that comes with it. One day, he decides to steal Christmas from the Whos, the little creatures who live in the town below him. He steals all their presents, decorations, and food, and hides them away in his cave. But he soon discovers that Christmas is not just about gifts and decorations, but about love and kindness.
