This mod is part of The Vanilla Experience.
A minimalistic configurable mod that tweaks the spawning behaviour of mooshrooms, allowing both red and brown to spawn naturally. Brown mooshrooms were added in Minecraft 1.14, thus older versions won't be supported.
onWorldSpawn (default = true): Transform red mooshrooms to brown whenever they naturally spawn in the world.
onEggSpawn (default = true): Transform red mooshrooms to brown whenever someone spawns them with a Spawn Egg.
becomeBrownChance (default = 0.5): The chance of a Red Mooshroom becoming a Brown Mooshroom.
