Bon Appetit! Achievement/Trophy - Fed a body to an alligator.
Guide: To earn this achievement/trophy you need to throw a body into an area which is inhabited by alligators and wait until they feed on it. When the game first starts and you get control of your character go into where the keys are located and pick up the body. Now take the body outside and throw it into the alligator pit, this will unlock the achievement. There is also another achievement/trophy tied with the Bon Appetit one named Next Time Swim Faster.
