When they were children, Josh and Hayley helped Santa Claus five times, they helped save Christmasland from that odious little elf Mister Bigwig. It has all been quiet for a long time, Josh and Hayley are now senior citizens and it came as a bit of a shock when Santa contacted them once more after all these years because he needed their help. This time it isn't Mister Bigwig it is a new foe who calls himself Professor Kringle; he intends to imprison the whole of the village of Christmasland inside Josh's magic snow dome and if no-one can get in or out of Christmasland this will prevent Santa from delivering the presents on Christmas Eve, so all the children will be disappointed. Professor Kringle is also demanding that Santa Claus hands over control of Christmasland and go and spend his retirement in the retirement home for elves and pixies at Torquay.The situation is serious.
