Trolls are said to have descended from the giants of ancient Norse history. They are sometimes considered to be harmful and mean to humans, but most people consider them more funny and mischievous than they are evil. In fact, troll stories are used most often to entertain and amuse children rather than scare them. Trolls are said to be especially friendly to children.
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.
