Blood Clot?[Well, now I know that if you need a suggestion to get attention, just ask SzGamer to look at it]
Anyway, I realise it's a good idea to add some more mobs, like Baconfry said. Gonna do that later when I have time. Also, the Blood Water Bolt is up for a name change if anyone can come up with something better.

CONCLUSION
I know that some people will say that the sun is supposed to be red, not the moon, but whatever.
Anyway, that was my Blood Moon Ocean suggestion. Thanks for reading! Feedback appreciated, sprites welcome!
