Miss Grinch

The Grinch is a furry, green, misanthropic creature created by Dr. Seuss, who lives in isolation on Mount Crumpet and despises the cheerful Christmas celebrations in nearby Whoville, leading him to try and steal Christmas by taking all the Whos' presents and decorations; however, he has a change of heart when he realizes the holiday's true meaning isn't material, thanks to the Whos' enduring joy, and he becomes a beloved, albeit still grumpy, part of the community.
