In a village high up in the mountains, people tell stories of the adventures of a young boy and his dog. Of how they climbed the steep cliffs with sleds on their backs, sledding down the mountain through the caves and jumping over the river, always coming back home safe.
Eventually an Alpine coaster was build in the spot where their adventures supposedly had taken place - if they ever even happened.
Regardless, the coaster became a huge tourist attraction, bringing boundless wealth to the villagers. And everyone was happy.
