This seed consists of two islands located far out in the sea and with just a few blocks apart from the other. Both islands are quite the same in size and holds the same features. It’s definitely a challenging seed because there are no trees on neither of the two islands. There are some patches of grass though on both of the islands which leave a chance of animals potentially spawning.
On the second island there is what looks to be an opening to a cave. Try to break a few blocks here and see if you find an entrance.
