Jack Skellington (The Chronicles of Poop)

''This page is about the parody villain. For the hero from The Nightmare Before Christmas, click here.''"Mayor, if you won't help me, take a hike! (Mayor: But Jack...) You might find a job in Christmas Town. And take your weenies with you! (Mayor: You're being an ass!)"

- Jack with the Mayor Jack Skellington is the (former) main antagonist of the YouTube Poop "Skellington's Revenge" by MoBrosStudios, the second installment in "The Chronicles of Poop" series. He is a parody of the Disney hero who is bent on taking over Christmas and the MoBrosStudios Christmas Poop.

His voice is taken from clips from the original movie, where he was voiced by Chris Sarandon, who played Prince Humperdink in The Princess Bride. His singing voice (which was also used in the poop) was provided by Danny Elfman.

Story
After his Halloween special is cancelled, Jack decides to take over the MoBrosStudios Christmas Poop special. He tries to figure out what to do and neglects his friends, despite them telling him he is being unreasonable. After a massive cocaine trip, he finally decides to summon the demon Black Hiver to help him take over the Christmas special. Black Hiver agrees, and together they travel to YouTube Poop Land and capture all of its denizens in a sadistic alternate dimension where Black Hiver and several monsters attack and tries to devour everyone to turn them into fuel.

When Spongebob confronts Jack, he tells that he decided to do this because he hates how Halloween specials are cancelled and underappreciated. He says he always wanted to bring a great special. Spongebob asks him why he did not just ask for help on a special and offers to share the special with him as long as he lets everyone free. Jack agrees, but Black Hiver arrives to attack. When Spongebob is captured, Jack reverses the chant he used to summon Black Hiver, releasing the captured souls, destroying the monsters, and killing Black Hiver.

When they return to YouTube Poop Land, Jack apologizes and Santa takes him away. He later appears with Santa, showing that all has been forgiven.
