the sea serpent. Its never there when you want it and always there when you don't, and its run-away-if-hurt mechanic makes it an aggravation to hunt, and its loot not floating (still!) means you have to drag it across the ocean if you want scales. It would be tolerable if its scales floated (yes, I know you can cheat this in). Its probably awesome as a group effort for new players. But solo, its just an annoyance that I can't bring myself to deal with, having done it a couple of times to see what its about. I just sink them with the crossbow and done now, and that is not too bad since i don't care to get the meat or scales, its fine. But its wasteful.
