Christmas with Princess Mirror-Belle. This special edition contains two stories and some festive things to make and do. Ellen gets a big shock when her reflection climbs out of a mirror. But Mirror-Belle is a double with a difference, she is a princess, and a very mischievous one at that. She sweeps Ellen into hilarious Christmassy escapades - from joining in with the Christmas ballet show to attending Ellen's friend's fancy dress party and trying to catch Father Christmas.
