The Forbidden Forest is forbidden or a reason. It's dark. It's dangerous. If an idiotic student enters it, they are not going to be coming out alive, so don't even think about going there. That being said, there are plenty of troublemakers who make their way into the forest for whatever reason be it stupidity or stupidity. But for those who are fool-hardy enough to brave the forest remember that there are giant spiders, centaurs, an old car, and wolves and other dark creatures in that forest ready to eat you alive. You have been warned.
