LEGO City Advent Calendar 2008 – If you wait very much longer this cool advent calendar will be sold out for Christmas. This calendar has absolutely nothing to do with the holiday, but kids love to open up the little parts every day at breakfast, counting down the days ’till they have more stuff to open. Make sure to get a little plastic box as well to hold all the little tiny parts. Once the tiny pieces are assembled, they come apart and end up all over the house.
