The switch to sheep should be more unique!

Viewing the snapshot 25w07a, I consider that there are things that could be used more than only the appearance of colors in a natural way, in my proposal, it would consist of:

- A change of texture or model depending on the biome (optional)

- Depending on the biomes, you can get a greater or lesser amount of wool (an example, in cold places you could get more wool, being a cold place the sheep must generate more to resist, In a hot place they would give much less)

- More rare variants according to the biomes, such as green, red and violet colors, and make the pink color even rarer)
