Alright, we'll leave it at that for you then. But I still believe it's fish most likely, cause most creatures that thrive in water covered areas always seem to go for fish or the like.
Yet some don't think so, It wouldn't hurt the show to have it. Just have them develop gradually and we got our characters, though the writing would take time to pull off.
Yeah, fics have done it, why wouldn't Hasbro? They've done some things from fics and put it into the show before, so it would be a little late to say so. So it wouldn't be bad for them to do it. It is a family show after all.
