Translations:Bioman/7/en
From DragonMineZ Wiki
Bioman spawn in snowy biomes (every biome in the #forge:is_snowy tag, such as Snowy Plains) in groups of 2–4, with spawn weight 60. Like the Saibamen, they spawn as monsters: not in Peaceful, only in dim spots (block light 7 or less), and only about a third of spawn attempts succeed. In Creative, the Bioman Spawn Egg spawns one.
