This seed starts by spawning you in front of a set of extreme hills, but if you walk forward, you’ll come across several interesting structures before ending up at a snow-covered tundra village. These structures include a dungeon, a plains village, and ice plains.
When you first spawn on this seed, you’ll be in a plains biome with a river splitting up the land around you. If you look forward and to the right, you can see the beginning of the savanna biome. Inside the savanna you’ll find a floating island, a village, and a dungeon all near each other.
On this seed, you can find both a village and a desert temple near the same river. While you could reach both through more direct routes than by the river, Pocket Edition doesn’t have coordinates to help aid in navigation. To ensure you don’t get confused or lost, I’m going to give you a river tour instead.
When you spawn on this seed, you’ll be in the middle of a forest-covered island. Usually, these types of seeds are good for a survival island scenario, but this island is too big and lush for that. It’s more like a luxury island with all of the wood and animals available.
However, the best part of this seed isn’t even on this spawn island. To find the double village, you’re going to have to do a bit of swimming. (Or rowing if you choose to take the time to build a boat.)
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.
