Have just found this on play.com for my niece who is princess mad. It is £12.99 on amazon.
Think its a great stocking filler.
A musical puzzle tower with 4 different melodies, one melody per princess. The goal of the game is to get the full image of a princess to hear her melody, the melody will sound each time an image of a princess is completed, you just have to turn the different discs of the tower! Batteries included.
