Bandit (raccoon)
Bandit was a raccoon which came to attention after being named "The World's Fattest Raccoon" by The Guinness Book of World Records.
He was born with a thyroid problem which led to his massive weight gain. He was adopted by a dog and raised as one of her puppies, then later taken in by a woman in Palmerton, Pennsylvania. At the time of his death he weighed almost 75 pounds.
