|Season 2, Episode 9|
|Written by||Jean Chalopin|
|Directed by||Bruno Bianchi|
The reason Santa's workshop has never been seen by polar explorers is because it's located under the North Pole. Once a year, Santa opens the passageway to the surface, but this year, M.A.D. is waiting and takes over the workshop to begin manufacture of a M.A.D. agent kit designed to hypnotize all the kids in the world and turn them into junior M.A.D. agents.
On Christmas Eve, someone sends a report to W.O.M.P., but Colonel Nozzaire thinks that it's a joke. However, Gadget still believes in Santa and heads for the North Pole stopping enroute at the Last Resort, the only hotel that far into the Arctic. Penny has stowed away in the Gadgetmobile and learns from Santa's undercover reindeer George that the resort is under M.A.D. control, just like Santa's workshop and the M.A.D. agents running it intending to dispose of her uncle before he makes it to the North Pole. Disguised as an elf and using a flying sleigh drawn by George, she gets her uncle to the North Pole, but it is unknown if Gadget can get into the workshop and save Santa and Christmas before it's too late.
- This is the second Christmas adventure in the franchise. The first was Inspector Gadget Saves Christmas.
