What is a norwegian troll?

In folklore, trolls typically appear as large, hideous, slow-moving humanoids, often with disproportionately large noses, hands and feet. Trolls are often connected to rocks and mountains and many legendary trolls have turned to stone. According to folklore, most trolls live in remote mountains, forests or uninhabited areas. Trolls can also move from one place to another but they are always careful to avoid sunlight, as this will turn them to stone. Trolls generally seem to avoid social contact with other humans, but it is possible for a human and troll to marry or enter romantic relations.
