Fungus is pretty gruesome on its own, but have you ever heard of zombie fungus? Well, you'll probably agree that the extra zombie aspect just makes it even more terrifying, especially as this stuff has actually been found in the forests of Bhutan, Thailand, and Korea. What makes this particular fungus so different is the fact that it quite literally uses animals as a way to survive. In fact, it latches onto their brains.
Yes, if an animal comes close to the fungus, the spores will spread into the animal's brain and force the animal to climb as high as possible to the top of the trees. Then, the animal will die, and the spores will spread even further.
