ok, well, you have to go around, like to find that bowl that that guys missing, go to the indians, and the other amaricans i think, while their @ war, climb the tree by hoping on the briantches. when you reach the top, theres a beaver with the bowl on the head, then go to the ppl who are missing the bowl, and give it to them...
