Rabbit spawn rate in the Flower Forest biome is unusually low
The spawn rate of rabbits in the Flower Forest biome is significantly lower than expected, according to the data available on the Minecraft Wiki.
https://minecraft.wiki/w/Flower_Forest
How to test (step by step)
Step 1: Create a platform made of grass blocks (grass_block).
Step 2: Build a second platform, 3x3 blocks in size, positioned 30 blocks above the first one.
Step 3: Place a Vindicator renamed to "Johnny" on the lower platform.
Step 4: Observe the rabbit spawn rate in the area.
According to the Wiki, the only passive mobs that should spawn in this biome in the Bedrock Edition of Minecraft are:
Rabbits
Glow squids (if water is present)
Even when considering the rabbit spawn rate in the Java Edition (4⁄44), practical results show that the spawn weight of rabbits in the Flower Forest biome is far below what would be expected in the Bedrock Edition.
The wiki is maintained by the player community and is not an official source of information for intended game behavior. In this case, the spawn weights for flower forests in Bedrock Edition are outdated. Flower forests now spawn all of the older animal types, and rabbits have a relatively low weight.
