It's a spell, I just forget if what's her name, Aurora's daughter, put it on her (I think) or if it's from something that happened elsewhere, but I don't think they've been back to the island again yet at this point. I can't remember, there's another storyline that's just what?!? and why is it necessary and how does it make sense. But you aren't there yet if she's only turned into a hag. Beast jr also wasn't in this one enough and dopey's son was under utilized. It really didn't need to be made but money.
