Mumble the penguin has a problem: his son Erik, who is reluctant to dance, encounters Amazing Hero Puffin called "The Mighty Sven", whom he thinks is a penguin who can fly. Things get worse for Mumble when the world is shaken by powerful forces, causing him to bring together the penguin nations and their allies to set things right.

In this four-part Christmas episode, Bart gets even with Santa Claus, Lisa dreams of an Inglourious Basterds-style Christmas, Marge receives a night time visit from the most powerful force in the universe, Martha Claus (Martha Stewart) who teaches her the true meaning of Christmas, and The Simpsons appear as puppets with pop singer Katy Perry.

When a group of singles, seniors, childless couples, teenagers, and homosexuals band together to protest having to accommodate families (including paying property taxes used to teach children they do not have), Marge takes up the cause for the families, with some help from Bart and Lisa.

Springfield adopts Marge's suggestion of a film festival, in which any of the townspeople can enter a short film. To help her judge, Jay Sherman comes from New York to stay at the Simpsons' house. Homer feels threatened by Jay, and so Marge puts him on the panel as well. At the festival, the vote becomes deadlocked between Mr. Burns self-glorifying biopic and Barney's touching film about alcoholism. Homer, originally supporting Hans Moleman's film Man Getting Hit by Football, is convinced to vote for Barney's film, which wins the competition.
