Weight = spawn weight of the mob in its category · Chance = weight ÷ total weight of the category · Group size = how many spawn together.
In Java Edition 3 mob types can spawn in Mushroom Fields — passive mobs: Mooshroom; ambient mobs: Bat; underground water mobs: Glow Squid.
Mooshroom has the highest spawn weight among the passive mobs: 8 of 8 (100%) in Java Edition.
Yes. Java Edition lists 3 spawn entries for Mushroom Fields, Bedrock Edition 3. For example, Mooshroom has a weight of 8/8 (100%) in Java and 8/18 (44.4%) in Bedrock. Use the edition switch above the tables to compare.
Each spawn attempt first picks a category (for example hostile or passive mobs), then one mob of that category at random, weighted by its spawn weight. A mob's chance is its weight divided by the total weight of its category in the biome — so the shares in each table add up to 100%.
