2 New Mobs, The Busher, The Ambusher and Leaf piles

The Busher is a passive mob that can be found in every forest biome and it has variants depending one the biome. With this mob comes a new block, a layered leaf block (similar to layered snow) and it would generate as leaf piles in forests and in these piles Bushers would hide in them and if you're close to a leaf pile that has a Busher in it, it would jump out at you but it wouldn't damage you,

You can tame the Busher with some honeycomb and it will follow you but it does not attack enemies, you can feed the Busher 10 tree saplings and it would give you something in return (for example a slimeball or something equivalent). Each variant will give you something different and the sapling has to match its variant.

The Ambusher is a hostile version of the Busher that is more aggressive and faster and they move more franticly but they are rarer to encounter than the Busher. If you can trap the Ambusher then you can feed it a dead bush or a set amount and get something valuable in return.
