When you first spawn on this seed, you’ll be on a tiny island with nothing but some grass and dandelions. If you’re willing to do the swimming (or boating if you can find a tree to make a boat with), this seed holds much greater things than that, though. You can find a mushroom island (a very rare biome) and a savanna plateau M biome not too far across the ocean.
This seed spawns you in a forest, but not far away you can find taiga and extreme hills biomes. Better yet, the taiga contains a village with a blacksmith shop. This seed keeps on giving with a ravine next to the village, and llamas in the extreme hills not far away.
