From Minecraft was made, The animals bring great enthusiasm to the game however I recommend one thing to the game which is also a part of reality ( some of it.) The mobs should definitely DRINK water. like the cows,sheep and pig,etc. I hope this come in the 1.14 or 1.15 update because I notice there is nothing happening like it and it will bring great improvement
Why drinking water.
1. When HP is lost for e.g. sheep loses 4 hp of health by a wooden sword. It goes to water for replenishing health.
2.Makes the animals drop more food like the pigs instead of dropping 1-3 of pork chop let's say it's 2-5 instead.
3.walk 00.5% faster
4.having a chance of producing 2 babies which is 00.20% chance.
5.follow what it loves like wheat the sheep last longer even by following you even if you're 12 blocks away from it.
6.this is my last idea of it - players can let the animals drink water from water buckets and it does the same thing for the rest of the ideas.
