Adam, Bree, and Chase go on a rescue mission to Davenport's secret facility in the frozen tundra to save Dr. Evans from a volcanic eruption. Meanwhile, Principal Perry crashes in on Donald, Leo and Tasha's Christmas to tell them that she accidentally ran into their decorations and she has to wait for a driver to pick her up. At Dr. Evans' facility, there was an aftershock causing a crack in his gamma-sphere. Chase makes a temporary force-field around it and Adam, Bree and Dr. Evans planted explosives to the gamma-sphere, also destroying the secret facility. Later, Principal Perry cooks dinner for the family, but makes Donald pay for it. Principal Perry got a video game system but Leo wants a video game system too like Principal Perry's. The episode ends with everyone spitting out their food, as Principal Perry tells them that she has accidentally cut off a bit of her pinky while chopping the veggies.

Well, that is Davenport Industries: risking the fate of Mankind since 1992.
Chase: Can we patch the crack?

Dr. Evans: Patch the crack? Billion-dollar technology, unstable energy source... Sure, let's put a little chewing gum in there and see if that works.

Chase: Startin' to see why the hologram-wife left.

Donald: You know, after spending time with Perry, the Grinch doesn't seem like such a bad guy.
