A couple of simple survival islands where the spawn is on one of the larger islands. On the surface of the islands there aren’t many resources besides a tree on one of the islands. The terrain is mostly sand as well as some grass blocks which definitely makes the first night in survival a little bit more tricky as you don’t have a lot of trees for wood to create a shelter from.
Look upon the seed as a fun challenge and see how long you can last. If you’ve seen the movie Cast Away with Tom Hanks perhaps you can get some ideas of how to best survive on the island.
