The Secret World of Santa Claus Each episode usually starts out showing Santa Claus preparing for Christmas and doing some Christmas-related activities at his workshop. Then two recurring villains (Gruzzlebeard and his partner Dudley) show up trying to foil Santa's plan and ruin the hopes of children. The two trolls usually end up actually finding themselves in a trap that they constructed themselves and the show usually ends showing that all of Santa's things end up turning out fine.
