Where's Belle's Pink Dress, mommy?

I am so peeved right now.

    Alana keeps asking for Belle's pink dress and Jasmine's green dress.  She has a Belle doll and Jasmine doll I bought at the Dollar Store.  Both dolls came with two dresses.  As I type this, Belle and Jasmine are naked but wearing shoes.  I took all the cushions off the couch and dug everything out of the crack between the back of the couch and the springs.  I found a few small plastic animals, a dog toy and little bowl from a Littlest Pet Shop set, and some various things including the shoes that Belle is currently wearing.  But her pink dress?  Nope.

    I pulled out the refrigerator.  Did I find it?  No.
    I moved Alana's bed.  Did I find it?  No.
    Alana keeps asking where it is, but with a smile.  She asks me to take the cushions off the couch or look under the "fidgefader".  I think she is mocking me.  Really, I do!  I think this is some kind of grand practical joke.  The last time I saw the pink dress, it was on a Polly Pocket in the living room.  The doll and dress went *poof*.  They are NO WHERE.  This has happened before- like right after I bought Belle and she disappeared for four days, only for Alana to run off and fetch her so they could watch Beauty and the Beast together.

    I know I *said* I wanted a clever daughter...  I just didn't know what I was asking for!
