It was about these two kids who were anthropomorphic animals of some kind, I can't remember what. It had something to do with them being in deep sea, and I think sea slugs or sea cucumbers were in part of it? Also the artist used black, green, and a pale yellow (or off white?) a lot iirc. It wasn't explicitly horror, but I remember it having some scarier parts. I think I might've read it around 2015-2017, but I'm not 100% on that timeframe, and it could've been from before that.
