<P> The Grinch is a bitter , grouchy , cave - dwelling creature with a heart `` two sizes too small '' who is living as a hermit on the snowy Mount Crumpit , a steep high mountain just north of the town of Whoville , home of the merry and warm - hearted Whos . His only companion is his unloved , but loyal dog , Max . From his cave , the Grinch can hear the noisy Christmas festivities that take place in Whoville . Continuously annoyed , he decides to devise a wicked scheme by stealing their presents , trees , and food for their Christmas feast . He crudely disguises himself as Santa Claus , and forces Max , disguised as a reindeer , to drag a sleigh down the mountain towards Whoville . Once at Whoville , the Grinch slides down the chimney of one house and steals all of the Whos ' Christmas presents , the Christmas tree , and the log for their fire . He is briefly interrupted in his burglary by Cindy Lou , a little Who girl , but concocts a crafty lie to effect his escape from her home . After stealing from one house , he does the same thing to all the other houses in the village of Whoville . </P>
