This seed starts by spawning you in the midst of a roofed forest biome. This biome is pretty self-explanitory. It has dark wood trees that are big around and spaced close together so the leaves create a roof of sorts. The giant mushrooms scattered throughout make it an even better find.
This is just the beginning of this seed, though. When you walk through the forest, you’ll come to a river with a desert on the other side. That is where you’ll find the neighboring temples and the beginning of the savanna biome.
This seed spawns you in a roofed forest, or more accurately, on a roofed forest. When you spawn you’ll see you’re right on top of a giant brown mushroom. If you get down from that perch, you can explore the roofed forest what you can find among the large mushrooms and close trees. If you go to the left of the spawn point, you can even find an abandoned mineshaft.
Here’s a new one. When you spawn on this Minecraft PE seed you’re INSIDE a dungeon. The game starts you facing a wall inside the dungeon. Turn around and you’ll find you’re inside a dungeon. There’ll likely already be a zombie or two that has shot out of the zombie spawner headed your way!
Another 0.9+ see where you spawn on an island. If you tunnel straight down from spawn (after cutting yourself down from the tree you spawned on top of) you’ll fall into an abandoned mine shaft. Explore around and you’ll find plenty of ore.
