Haha you and I are of like minds Miel, I was about to start a thread about the same thing

I've found the serial number (on the bottom of her front right foot, right?) but I can't find the security code anywhere

I searched the box she came in and read and re-read all the numbers on the bottom of all of her feet, but all I can find is that the code is supposed to be 4 numbers, and she has more than that on her feet. Did you find it? Or did anyone else?
