Actually to be entirely accurate it isn’t two islands but very close to it. A couple of blocks are actually combining the two blocks together. But with a little help of some terraforming that shouldn’t be an issue for long!
The spawn is on the greater island which is covered by lots of trees which make the island a perfect start point to gather wood for a house.
The only downside we could find about the seed is that there are not a lot of animals. We couldn’t find any but then we didn’t look in every corner of the seed so please tell us in the comments if you find any animals.
