Midden in de Winternacht plot
A week before Christmas, Max sees a very large moose fall through the roof of the barn. This moose, named Moos, turns out to be able to talk! Not only that, he also works for Santa Claus. Moos always makes the test flights with Santa Claus, before the reindeer do the real work at Christmas. Unfortunately, Moos has lost control of the sleigh and Santa has crashed far away from him. So now he has to find Santa Claus as fast as he can, otherwise no one will get a Christmas present this year. Will Max and Moos be able to find Santa Claus and get the sleigh back in the air in time?
