Or regular underwater enemies? Those are some of my bigger feared enemies. It's not like I NOPE out of the game though, I go and fight those bastards but it's unsettling.
I almost couldn't fight that one colossus in SoTC because it was a big underwater dragon serpent or something, but then I conquered that punk and have been mostly ok since. --- If I get a girlfriend, I'd like to take her into a cardboard box.
