Trolls are looking like humans, but they always have small features that shows that they are trolls, that can for example often be a little tail. There are some different types of trolls, some are very ugly while others are very beautiful. There are very hard to se a troll because they are very shy and they can also transform into other things like a stone, an animal or a chair. Many of the trolls are very old and they are counting their age after how many woods they have seen growing up and rotten down.
It is not just their appearance that is the same as humans, they also live like us. They can have animals and neighbours and so on, but they live under the ground or in caves in south and middle of Sweden.
