Cave Trolls inhabit the caves under the Highlands, known as the Troll Caves. These creatures will attack with surprising speed in the same way a Golem does. Cave Trolls will rarely drop Magic Beans when killed, if you are lucky. The Trolls resemble Villagers, only larger and covered in warts. The Troll Caves are full of them, as well as some Vanilla mobs, so bring a weapon (a bow is recommended).
