Trolls are magical beings who appear in our lives to accompany us, help us, and even protect us. Their origin dates back to Norse mythology. They have a highly developed sense of smell, measure 7 to 11 centimeters, and live in mountains, hills, caves, tunnels, and underground. They are nocturnal creatures and eat everything, including stones and metal, because their gastric juices are extremely corrosive. Their hunger is difficult to satisfy. They were once persecuted by Thor and have a great fear of iron objects.
