Hilary Duff and Haylie Duff lend their voices to this heartwarming animated tale for the holiday season. Princess Crystal (voice of Hilary Duff) is a penguin who one day finds a sleigh bell. Crystal is certain that it came from one of Santa Claus's reindeer, but not everyone else is convinced, so Crystal and her sister Lucinda (voice of Haylie Duff) decide to go to the North Pole and take the matter up with Kris Kringle himself. The sisters discover there's lots of adventure and a bit of danger along the way, which is compounded when they discover their parents at home are in danger of losing their place in the penguin monarchy.
