Halloween, Oh Halloween

So recently the topic of Halloween came up with Mad Molly, who completely remembers dressing up as a bee for Halloween last year. (her recall skills are outstanding, much to my dismay). Anyway, Mad Molly briefly decides she wants to be Ming Ming Duck (her favorite character from her new top show Wonder Pets) Ming Ming for you who don't know is a 3 year old duck who wears a flying bomber hat and goggles), thankfully this request was short lived and she moved on to and has pretty much stuck with wanting to be a Butterfly! Until now.... the other day I started making a Halloween costume for my goddaughters Grace and Emma who are going to be adorable Candy Corn Witches. Mad Molly asks me what I'm doing and I tell her I'm making a Halloween costume for Grace, to which she says, I want one ... puzzled I ask her you want to be a witch like Grace? and our conversation went like this

Mad Mommy: You want to be a Witch like Grace

Mad Molly : Yup, you make me one like Grace

Mad Mommy: Ok, I'll make you a witch costume for Halloween

Mad Molly: Nope a butterfly

Mad Mommy: You want me to make you a butterfly costume

Mad Molly: Yup, just like Grace you make me one

Mad Mommy: Oh, you want mommy to make you a butterfly Costume

Mad Molly: No, you make me just like Grace

Mad Mommy: So you want to be a witch

Mad Molly: No a butterfly

Mad Mommy: you want to be a butterfly

Mad Molly: No like Grace

Mad Mommy: ?????????

if anyone can figure out a way out of this loop, please let me know because our Halloween debate (which by the way she thinks "Halloween" is a person) continues and I have no idea what she will actually be for Halloween!
