Biome Dependent Sheep Varients for the Next Drop!

Sheep Varients have been rejected because they can come in different colors, but what if instead of a color varient, they had a larger coat of wool in a colder biome, and a smaller coat of wool in warm biomes, also with a normal coat size in temperate biomes! =3 Maybe even a warmer tint in warmer biomes, and a cooler tint in cooler biomes, and no tint in temperate biomes (this tint is kind of subtle, yet still noticable!)

(plus horns for one of the varients(or the chance for a sheep to spawn with horns(rarely)))
