When Santa tries to take over Halloween, it's up to the Titans to save the holiday.
On the night of Halloween, the Titans plan to scare the trick or treaters, but there is no candy or decorations. When all hope is lost, it is revealed to the Titans that Santa took all candy and decorations. Santa chases the Titans back to the Titans Tower and tells the Titans he will not leave until the Titans give Santa the last bag of candy.
The Titans almost win, but Santa pins Halloween Spirit, and the Titans give Santa the candy in defeat. But, they had swapped the bag of candy for a bag of TNT who Santa says "Wait, a minute these are not treats," and Titans reply saying: "They're TRICKS!" before catapulting Santa into the North Pole. Then, once Santa reaches North Pole, he does a tiny fart then it switches to the Titans doing their victory dances.
Then the Titans recreate Halloween (to the Thriller Song), and Robin shouts: "Merry Halloween to all and to all a Scary Night" then the moon laughs evilly.
Like "Halloween" & "Scary Figure Dance", this is a rarely seen episode, meaning that it only airs around October. This episode also aired around December in the Titans Vs. Santa marathon to celebrate the holidays.
Although, in Latin America and Brazil, reruns of this episode air almost every day on Boomerang.
Halloween Spirit makes a second appearance in the series. His first appearance was in "Halloween", but this time appears as a gourd, as his original vessel (a pumpkin) was smashed in his debut episode.
He also appears as a helper to the Titans instead of a antagonist.
When the Halloween Spirit makes Santa's sleigh into a Halloween sleigh, a song that sounds like Thriller by Michael Jackson plays.
When the Halloween Spirit summons the other monsters, Night on Bald Mountain plays.
Santa uses his candy cane as a sword in the same way that he does in the 2012 Robot Chicken Halloween special when fighting the Great Halloween Spirit.
One of Santa's elves does the Peanuts dance.
During the chase scene, Santa's elves board the T-Car using candy cane poles. Similar stunts were performed in the 2015 film Mad Max: Fury Road.
Robin calling Santa Claus "Kringle" is from the 1943 movie Miracle on 34th Street.
The Christmas songs Santa plays to the Titans are:
We Wish You a Merry Christmas
O Christmas Tree
Deck the Halls
There is a mask of Stripe from the 1986 film Trick or Treat at the Halloween store.
The plot itself bears resemblance to the 1993 film The Nightmare before Christmas directed by Tim Burton, which is about Jack Skellington, the king of Halloween Town, taking over Christmas, similar to how the Titans attempt to recreate Halloween.
In some dubs of the episode, in the scene where the Titans gasp when the Halloween Spirit is defeated, the Titans's original voices from the English dub are heard instead of the dubbed ones.
This used to happen in the Latin American premeire but was later fixed.
Beast Boy keeping stuff in his pants "just in case".
Santa calling the Titans "garbage children".
