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 17 mob types can spawn in Frozen River — hostile mobs: Creeper, Skeleton, Slime, Spider, Zombie and Frostbite and 4 more; ambient mobs: Bat; water mobs: Squid; fish: Salmon; underground water mobs: Glow Squid.
Creeper, Skeleton, Slime and Spider share the highest spawn weight among the hostile mobs: 100 of 541 (18.5% each) in Java Edition.
Yes. Java Edition lists 14 spawn entries for Frozen River, Bedrock Edition 11. For example, Skeleton has a weight of 100/541 (18.5%) in Java and 24/270 (8.9%) 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%.
