Description
Why should we be nice? That is the rhetorical question that drives the Cocogibbons. It's just not in their blood to communicate rationally with any creator other than themselves. And even with their own kind, they get violent whenever food or valuables is involved. Either avoid them or offer them something convincing in exchange, otherwise they will not hesitate to let their coconuts fly.
