"The Christmas Dragon: 230th episode overall and the season finale, premiering on December 16, 2022. Segment One (Invention Exchange): After a brief introduction from Kinga and Max and an address by Dr. Kabahl, the three hosts present their inventions (all of which are secretly part of their escape plan). Jonah has created a B-52 head for Tom Servo, Joel has a perpetual-motion steering wheel, and Emily has a paperweight that looks like a cinder block. Kinga and Max scramble to present the Missile-toe, an explosive rocket with mistletoe on it. Segment Six: The hosts attempt their escape plan, performing "Hooray for Santa Claus", "Patrick Swayze Christmas", "O Holy Night," and the MST3K theme song (though Joel claims that he "only knows the lyrics to Mike's" version). They get some unlikely help when Pearl, who has known their plan all along, begins towing them with the Deep Hurting. In the end, they all escape through the "Time Bag" to Earth in 1991. Dr. Kabahl revokes Kinga's funding and calls in her loans, and the Kingadome is struck by a meteorite."
