3 New animations

So with the new frogs and the camels getting new animations to match, it makes sense to add new animations to make minecart feel like real life. Too change this I suggest 3 new animations for 3 old mobs. 1st being the sheep. So occasionally I think it would be fun to make the wool cube, of any color, to shake around "as in the cube rotating" as the dog would do in the rain. 2nd would be the Skeleton. When it hasn't seen any players in a while, at night, it would test it's bow to see if it works. This wouldn't fire an arrow because when actually testing a bow, you don't put any amino in it. And maybe seeing a Skeleton do this with a spyglass can get you an achievement "Miss Fire" or another name. And now lastly the 3rd mob to get something new is the Polar Bear. I think it would be cute and funny if the bear can sit, like a Panda, when it is bored or has a bored character trait. It can just sit like that but when a player drops food, normally or only a type of fish, it would role towards it. And the achievement that can go with that can be "they see me rolling".
