Mushroom Islands And Icepeaks Seed 1.15.1/1.14.4 – Views (104)
Using this seed, you will appear near the border of two very rare biomes: a mushroom island and ice peaks. This is a rather specific area, it can even be called hardcore, because finding trees near the spawn will be problematic. If you are going to explore the world, and not stay in place, then go to the coordinates -240 ~ -270, here you can find a small island with a village.
