The naughtiest reindeer takes a bow

While all the other reindeer are sleeping, Ruby sneaks off with the present-laden sleigh in an attempt to get a head-start on the Christmas deliveries. Disaster! So when she crash-lands at George and Amelia's house, she abandons the presents to join them in the school concert. What could possibly go wrong? And what will Santa do when he discovers his sleigh (and all the presents) are missing? Will he be able to save Christmas?
