Just look under the sea in real life and not say it's music to me. Seriously, the deep sea is a messed up place that even a horror artist like H.R. Giger would say, "Okay, that can't be unseen. I just saw a tiny spider eat itself alive."
Anyways... probably has scribs in spider form, as well. Mars could have had tons of Morrowind creatures before it became a wasteland.
