That's probably because it is.
Looking at some of the other, related images, and at how the substance in question acts, it might be that it's chocolate, though it may very well be mud - especially when you consider that this image is at the hot springs. I'd guess that if you actually played the game, you'd know, but having not played it, I don't know. I do think that it's safe to say that it's not worse than mud though.
