The Longest Night. On Christmas Eve, Santa reveals some of his most greatest secrets. Having his elves drink a special syrup, he shows them the Master Clock, a device that can stop time so he could make his runs every year. Those who drink the syrup are immune to its effects. However, Gruzzlebeard takes two glasses of the syrup, planning to destroying the clock so that Santa can't complete his run. While Guilfi and Balbo are left behind to watch over the workshop, Santa, Jordi and Thoren go out to deliver all the gifts. Gruzzlebeard gives Balbo trick honey that makes him sleep and trapped Guilfi in a cage. He then proceeds to destroy the clock. Instead of what he was expecting, everything else in time went backwards, right back to the prehistoric times. The others return the North Pole, free Guilfi and head inside the room where the Clock is. They were able to fix the damage and fast forward time to its original point. Gruzzlebeard tries to trap them in the room but realizes he hammered the wrong nail which Dudley pointed out. Guilfi is invited on the Christmas run while Dudley and Balbo keep Gruzzlebeard occupied by throwing snowballs at him.
