maybe ursala became evil and her evil "deformed" her. or maybe they are the children of a merman and an octopus? maybe she changed herself. maybe their parents were like, "gods" and their children differed, like the eygptian gods...

Maybe there was a fight between triton and ursula and triton turned usula half octopus.
