This seed is interesting in that at the start it generates a very beautiful cave with waterfalls. This picturesque place is perfect for building something unusual, but first you will need to get rid of an impressive number of hostile mobs. It will also please you with a desert with temples and villages in the west and the sea with a large number of ships in the east.
