In a faraway land where the water shines like silver and the mountains are as high as the sky, there lived a little Viking named Santa Claus. Santa had armour made of fish scales and a helmet on which sat a colourful bird. Every morning, Santa greeted his cat Tosia and his friend Olek, who wore a pink hat. One day, when the children were playing on the shore of the fjord, they suddenly heard a quiet rustling in the bushes. A little troll came out from behind the trees and whispered: - Santa, I saw a dragon! It is as green as moss and lives where the forest ends.... Santa looked at his friends. Their hearts started beating faster than a drum for a Viking festival. Is it possible that a real dragon lives in their village? They looked towards the dark forest for a long time. Who would be the first to dare to go between the trees? The friends grabbed each other's hands and took the first step towards the great green adventure....
