The Grinch's favorite food is onions, he often devours them by the handful, raw and with the skin still intact, not caring that it gave him bad breath and foul smelling belches. And to top it all off, The Grinch is also a heavy smoker, the Grinch smokes about four cigars per day, and also smokes cigarettes on occasion. His teeth are yellow and rotten, and his voice is raspy and gruff as a result, adding to his often rough and unpleasant demeanor.
