In "The Magic Stick Of Manitou" episode, we find out that the beautiful music on his planet is played on a flute made from human bone. Ok this is a little creepy if you're not used to this kind of thing, but many cultures use bone (both human and animal) for instruments and clothing, etc. so it's really not that scary if you think about how many cultural traditions include this. I fail to understand why the flute being carved of bone is supposed to be so scary and why we are supposed to be so terrified at the end. I say, it's kinda' like, so what? Of course, we are suppose to deduce that that other guy was killed and they used his bone for the new flute. But even so, isn't this what many cultures have done - even on this planet? They use the remains of the dead for all kinds of things.
