Danny Phantom (2004)

Season 2: Episode 8

Danny Fenton hates Christmas. When he accidentally destroys the only copy of a ghostly Christmas story, the book's author, Ghost Writer, 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, Ghost Writer 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 Ghost Writer, he is surprised to find his old ghostly enemies in a giving mood. Danny enlists them to help him defeat Ghost Writer and restore the spirit of Christmas to Amity Park and, perhaps, to his own heart.
