The Hide behind

I was thinking maybe thare could be a mob that is kinda like a ender man but it can't teleport and looks like wood and only spawns in forest, it would try to stay behind a player and will take damage if looked at by the player, it could be attracted to noise, possibly drop silent bark (I can't think of a better name) that could be crafted into silant boots that would make the hide behind neutral to the player and also make mobs that can't see you not hostile to the player.
