How do I find mushroom biomes?
Minecraft's mushroom biome sounds like a pleasant place: Food in abundant supply, and zero hostile mob spawns.
However, in all my time playing, I've never ever found one. Is there a trick to finding them, or do you just have to get lucky?
It's important to realize that mushroom biomes only spawn as islands in the middle of oceans.
So, if you want to look for one in a world that doesn't spawn you in one, you can't go walking to find one, you need to find an ocean, make a boat, and search the ocean for a mushroom island.
I can't offer any personal experience of how easy it is to find one by that approach (I've no idea whether most oceans contain one, more than one, or just have a chance of containing one).
I'm afraid you have to get lucky. Your best bet is to start a world with a seed that spawns in a mushroom biome, e.g. lost.
...or swim for a long time until you find one.
Install the planes mod, build a p-51 with a radial engine, and have fun exploring almost faster than the map can load/generate. This should make locating mushroom biomes a lot faster.
Well, I'm not bragging, I was really lucky. In my Legit survival world I found a mushroom biome. And here are some of my tips to find them:
Scout the Ocean. Make sure that the ocean is big and don't go next to the coast line, just keep the coastline visible in the corner of your eye.
Scout all coast lines of your map. Since oceans are pretty much endless, you can walk on the beaches until you find one that is connected to your beach (worked for me)
Use a seed with one either near, or in the map near spawn.
Mobs cannot spawn on mycelium and the best way to find one is to make a boat and explore out in the middle of nowhere, kind of like finding diamonds.
