With ocean sight, and writhing flesh, instead of the usual writhing flesh message, I got a message saying
"Your wounds knit over with thousands of tiny, staring eyes."
I'm guessing this is because of my pulsating eye I had equipped. Equipping a disgusting slug doesn't seem to do anything else, despite also being a spawn of nightmare fuel. I also only got it against the subway madman, but I didn't get enough time for a thorough test.
