This seed spawns you in an area with three big biomes, mega taiga, jungle, and extreme hills, and they’re all right next to each other. Each one has their own set of benefits, and each has its own large feature either in the form of trees or hills. On this seed, you don’t have to decide which biome you want to settle in. You can pick all of them.
As far as appearance goes, this seed isn’t very special. Just some desert, plains, and forest biomes. However, this seed holds potential underground. With both a desert temple and an abandoned mineshaft, there are sure to be plenty of chests full of loot.
This seed has a rare mesa biome and a swamp biome to make it even more unique. The best part of the seed, though, lays just beyond the swamp in the second section of the mesa. There you can find an abandoned mineshaft with chest minecarts out in the open that have a chance to contain diamonds. That alone makes this seed worth it.
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.
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.
