Tribe of aborigine

In the forest, for example, there are "aborigines". They lives in wigwam, which is build whith branches. They are neutral, but in case of attack they become enemy (all tribe attacks even if only one of them was attacked). By default they are curious. You can deal with them. They give you something random for any tool or gold. But most often they give the spear (you can kill with them zombie, creeper, skeleton and so on by one throw) and some bananas. If you play music on Jukebox, you become leader. And their behavior becomes like wolf (they follow you, protect and so on).
