Title card.

"Scary Godparents" is the Halloween special of the animated series The Fairly OddParents. It first aired on October 29, 2002 in the United States on Nickelodeon.

Plot

Timmy wants to dress up for Halloween as a Jackobot from the "Crash Nebula" episode, but the rich kids have the only four existing Jackobot costumes. When Timmy has to go out in a cheap costume, he hardly gets any candy while he is trick-or-treating and when he does get some, he has to give it to Vicky. The rich kids get all the candy because their costumes are real. Timmy wishes all the Halloween costumes real and scary, but when Mark the alien comes and the Jackobots plan to destroy the world, he has to do something about it.
