Trolls are very large and equally ugly. They live in the cavities of rocks and trees and in caves. They have large feet and a keen sense of hearing and smell, which is important as they have very poor eyesight. They have tough skin and a lot of hair. They also have tails.
Trolls are extremely strong yet lacking greatly in intelligence.
Still, they can be conniving tricksters, and are always looking for ways to get food or shiny gold and jewels from humans. Many times, however, trolls are caught in their own traps. Yet it is not easy to kill a troll. One story goes that if a troll comes to eat you, you must offer to feed him a lot of food first. Then, when the troll isn't looking, you put a backpack on your stomach.
