Some of you may have noticed the bones laying around Io. When asked about it, a developer did admit that the bones were left there on purpose and not just for aesthetic. So this brings up the question: Who do the bones belong to and why are they there? Personally, I think that they're the remains of underwater animals like whales or something because of all the shells and fossils of hermit like creatures buried with them. Maybe Io could have had an ocean at one point? I'm curious too see what you guys think!
