Overview:Robot Chicken's Christmas "whodunit" spoof. There's been a murder on the North Pole Express and since each passenger could be the killer only Jesus can solve this tough case with many twisty turns. The suspects include Santa's frienemy Krampus, Santa's stereotypically Jewish nutcracker accountant called Nutsy Goldberg, Snowball the snowman, Santa's inquisitive reindeer Comet, Christmas elf Peppermint, Santa's gingerbread girlfriend and singer Ginger, the train's accommodating porter and, of course, Tim Allen.
