He's a mean one, Mr. Grinch. Not only is the evil green creature always in a foul mood, he steals all the presents and decorations from Whoville to prevent the holiday from coming to town. He makes his loyal dog Max dress up in an uncomfortable reindeer outfit, and then makes the tiny pooch lug a heavy sleigh full of presents while he gleefully stacks more weighted items on top of it. Worst of all, he lies to Cindy Lou, the smallest and most innocent of the Whos, almost ruining her Christmas. Although his heart does grow three sizes larger by the end of the tale, the Grinch probably causes the girl years of therapy after she witnesses Santa break into her house and rob her of her possessions.
