The sand is covering something...
It's some kind of organic sensor.
That's a weird rock. It just doesn't look...natural.
It's a large shell. I wonder how deep it goes, and what it contains.
I'm so deep now, I really should have been crushed by the pressure, but I feel fine. Wet, but fine.
I'll worry about my appearance later.
Hello? Is there anybody in there?
Spooky. Well, I guess it's an invitation of sorts.
It's soft and spongy.
It feels more like a shell than a rock. Uh, I don't think this is a rock. I think it's...alive.
