Seed – Spawn is on one of three small islands.
None of the islands have trees and this greatly complicates your survival in Minecraft PE. But do not worry, if you look in one direction, you will see the mainland in the distance. On this continent you will find all the necessary resources: food, trees and more …
One of the three islands has an empty interior, you can see it in the image below. If you destroy any block of sand on the surface, then other blocks will simply fall off and you will see the inner emptiness of the island.
