What the hell is a ranta? They leave a lot of poop in caves that don't have atmosphere.

It's just a little guy. It's like a little isopod-looking guy that scuttles around the caves and leaves funny-shaped poop.

And doesn't need to breathe.

Yeah, it can survive in a lot of different atmospheres. So it's kind of a large isopod moving around and kind of sucking up different minerals and stuff, which is why its dung is valuable. The cube, that kind of different-shaped dung, is inspired by wombats, who are a real-life thing, have a fun-shaped cube.

Have we ever shown what it looks like?

I don't think we have concept art for it yet. I'm not sure it's approved.
