The Grinch is a bad-tempered green hairy creature who lives inside a snowflake in a cave atop Mount Crumpit. The Grinch's heart is two sizes too small and the two things he hates most in the world are Christmas and the Whos who live in Whoville at the bottom of his mountain.
One year, he decides to put a stop to Christmas once and for all and steals all the presents while the Whos are asleep on Christmas Eve. But, the Whos still celebrate Christmas Day and with the help of Cindy Lou, a little Who girl, The Grinch finally comes to learn that the true spirit of Christmas goes much deeper than tinsel and toys.
