When using this seed, you can find a rather unusual structure: a mansion in the mountain. Part of the house is right inside the cliff, which looks very interesting. This makes it possible to climb onto the roof without cheats, simply jumping onto it from the top of the mountain. If you want to quickly find the mansion, then go or teleport at coordinates 415 500.
