Now in this biome can spawn Allays! like the minecraft live 2021, sad... (I would like to modify the feature of birch trees but I don't know how)

Also
now can spawn
- Bees! (naturally, without hive)
- Rabbits!
- Donkey! (rarely)
- Tropical fishes!
- Salmons!
- And frogs!

The color of the frogs in images is from a previous texture pack on my profile :)

Now, the old growth birch forest look more alive!
Enjoy!
