Cow Improvements

With cows being really old in Minecraft, I thing it would be great to dust them off the shelf. Being able to milk them whenever you want and however much you want. If a cow is out of milk (or a mooshroom is out of stew) there should be an indication that the cow is out. Maybe a special noise or its udders turning blue (that would be funny). To gain back it's milk (or stew), cows could eat grass. If a cow eats mycelium, it should be able to turn into a mooshroom, and a mooshroom can only gain back its stew by eating mycelium. Also, with shears being able to shear sheep and are going to be able to shear mooshrooms in 1.14, since buckets can pick up water and lava, I see no reason why they shouldn't be able to milk cows and collect stew from mooshrooms. Speaking about mooshrooms, I feel having brown mooshrooms just be another addition to the mushroom biome wouldn't be enough. I think brown and red mooshrooms should have their own separate biomes, maybe with different mycelium, or brown mooshrooms could be an underground variant of mooshrooms. Seeing big underground areas, or maybe little underground mooshroom towns would be something to explore. Maybe brown mooshroom towns could either 1: only be found under mushroom biomes, or 2: be a rare structure or it's own vertical biome found underground. I know this looks like much, but I feel it would be great to have some changes to cows, mainly to just have a bit of fun with the silliness of mooshrooms.

I think it would fit in with the rest of Minecraft and not just be there just because I want it.

Also, just to add onto the silliness, this isn't that important, but I think they should also add a cow button. Stays pressed as long as stone buttons, but makes a little "moo" sound. Would be crafted with one leather.
