well, I'm thinking that one of the Wicked Witches did the curse or even Mombi [since we know she's a witch and she is able to change appearances like she did to Ozma/Tip] but right now, the bunnies are trying to figure out how the logistics of the how/when/why of the curse [how did the curse happen - motive; when did it happen - obviously, pre-Dorothy's arrival, but how long before her arrival; if WWoW cast it, why didn't it break when she died; since the curse hasn't broken yet, what has to be done in order for the curse to break]
