Jimmy is convinced that Santa Claus does not exist. To prove his theory, he travels to the North Pole with Carl and Sheen where they discover a remote toy factory. When Jimmy's homing device malfunctions, it emits a blast of energy that hits the source of the signal - Santa Claus. With the big guy's atoms temporarily scrambled, who can deliver the presents? Jimmy must now put his doubts aside, load up the hypercube, and try to save Christmas before the people of Retroville have to settle for a new holiday - "Pule Day".

Otis convinces his college buddies Donner and Blitzen to stop by the barnyard on Christmas Eve night. During the visit, Otis accidentally gives Santa a cup belonging to the sick Freddy.

Danny Fenton hates Christmas. When he accidentally destroys the only copy of a ghostly Christmas story, the book's author, Ghostwriter, makes Danny hate the holiday even more by turning him into the main character of a brand new Yuletide tale. Danny is now trapped in a scenario where everyone talks in rhyme! With his magical Quantum Keyboard, Ghostwriter creates a series of catastrophes that threaten to ruin Christmas for all of Amity Park and pins the blame on Danny. When Danny goes into the Ghost Zone to confront Ghostwriter, he is surprised to find his old ghostly enemies in a giving mood. Danny enlists them to help him defeat the Ghostwriter and restore the spirit of Christmas to Amity Park and, perhaps, to his own heart.
