->'''Twas a long time ago,'' \\
''Longer now, than it seems.'' \\
''In a place that perhaps you've seen in your dreams.'' \\
''For the story that you are about to be told'' \\
''Took place in the world of YouTubePoop.'' \\
''Now, you've probably wondered where Creator/MoBrosStudios has been.'' \\
''If you haven't, I'd say it's time you'd begun...''

A YouTubePoop created by Creator/MoBrosStudios, '''''[[https://www.youtube.com/watch?v=CQn-z3eVgno The Nightmare Before Christmas Who: Skellington's Revenge]]''''' is [=MoBrosStudios=]'s longest and by far most complex video, clocking in at a whopping 21 minutes.

The story begins on October 28, 2012, when [=MoBrosStudios=]'s Halloween special has been cancelled. Despondent, [[WesternAnimation/TheNightmareBeforeChristmas Jack Skellington]] stumbles upon the upcoming Christmas special, and decides to take it over. Meanwhile, in [[WesternAnimation/SpongeBobSquarePants Bikini Bottom]], Sandy introduces [=SpongeBob=] to the concept of Christmas, and soon all of Bikini Bottom is getting ready for the festivities - even characters from other franchises join in the fun. However, Jack will stop at nothing to take over Christmas, and ends up making a DealWithTheDevil that may ruin the holidays for all.

Considerably DarkerAndEdgier than many of [=MoBrosStudios=]'s productions, ''Skellington's Revenge'' is notable for its extensive use of effects and video editing, particularly in the second half of the video. For the characters featured here, see the [[Characters/TheNightmareBeforeChristmasWhoSkellingtonsRevenge Character]] page.

!!Provides examples of:

* AdaptationalHeroism: While heroic on occasion, The RED team is still a group of crazed mercenaries who work primarily for money. Here the RED team is outright altruistic and starts the fight against [[spoiler: Black Hiver.]] Eddy is also much nicer here than in his own show, though that can be justified by this taking place after his HeelFaceTurn.
* AdaptationalVillainy: Jack Skellington is the BigBad who's more than willing to hurt people to get what he wants, albeit this was after his Halloween special got screwed over.
* AmbiguouslyGay: [=SpongeBob=] appears to think Squidward has a crush on Terry Crews; even writing a love letter in Squidward's name.
* AnAssKickingChristmas: The second half of the video becomes this.
* AnyoneCanDie: [[spoiler: Everyone who enters the Black Hiver's dimension except Santa and Jack DOES die at one point or another, even if it's undone.]]
* ArmorPiercingResponse: [=SpongeBob=] gives one to Jack after the latter [[MotiveRant explains]] [[StartOfDarkness why he set out to take over Christmas]].
-->'''[=SpongeBob=]:''' Why are you doing this?
-->'''Jack:''' ''Why?!'' Why should Halloween be cancelled year after year?! Why should our years of hard work go unrewarded? All I ever wanted was to bring them a ''great'' special… AND THAT'S EXACTLY ''WHAT I'LL'' '''''DOOOO!!!'''''
-->'''[=SpongeBob=]:''' [[YouDidntAsk …Well, why didn't you just ask?]]
-->'''Jack:''' ''({{double take}}s)'' What?
-->'''[=SpongeBob=]:''' We can share it!
* AxCrazy: Mr. Krabs appears to be, considering he only asks Santa for ponies so he can have their rear ends [[SuddenlyShouting CUT OFF!!]] [[LargeHam AND MOUNTED!! OVER HIS-]]
* BackFromTheDead: [[spoiler:All the heroes who die are brought back to life at the end. Lampshaded by the Heavy, who shouts "WE LIVE!" as they all emerge victorious on Christmas Morning]].
* BadassCrew: The entire group that gets [[spoiler: abducted by Jack and Black Hiver.]]
* BerserkButton: [=SpongeBob=] apparently presses Jack's (who's disguised as Santa), when he asks him where his "big, round belly" is.
* BigBad: Jack Skellington, though he redeems himself in the end.
* BossSubtitles: [[spoiler: BLACK HIVER: SADISTIC HOLIDAY DEMON]]
* BrickJoke: Near the beginning, Squidward comments on how he can't believe anyone would celebrate a holiday where "some jolly prowler poops onto your house and leaves." Guess [[ToiletHumor what ends up on Squidward's roof]] near the end of the video?
-->'''Squidward:''' Yep, I'm insane.
** Early on, [[Series/EverybodyHatesChris Chris]] gets stuffed into a bottle and launched to the surface for asking for Playboy magazines. During the ending when Santa is telling off Jack, he points over to the bottle Chris is stuck in, saying he's the only person who makes any [[strike:sense]] soup around there.
* ButtMonkey: Patrick gets this the worst out of all the characters. First, he loses a video game which causes him to crash and fly out of control into the air, resulting in him getting eaten by Cerberus from VideoGame/DantesInferno. Then he gets crushed under the [[VideoGame/TheLegendOfZeldaOcarinaOfTime Great Deku Tree]] after chopping it down from below, kicks Heavy and gets blasted with sugar plums in retaliation, gets impaled from below by the Christmas tree he launched himself onto, and then he gets killed and eaten by Patchy the Pirate.
** [[Series/EverybodyHatesChris Chris]] tries asking [=SpongeBob=] to send a Christmas list of Playboy magazines, only for him to retort [[Film/AChristmasStory "You'll shoot your eye out, kid!"]], stuff him into a bottle and send him right to the surface. Also, [=SpongeBob=] and Santa both mistake him for a little girl.
** Squidward, who not only gets torched by Mr. Krabs for mocking Christmas, but gets a car rammed through his house and a giant mound of poop put on his roof.
* TheCameo: [[WesternAnimation/MyLittlePonyFriendshipIsMagic Derpy Hooves, Pinkie Pie]], WesternAnimation/PhineasAndFerb, [[WesternAnimation/CourageTheCowardlyDog Eustace Bagge]], WesternAnimation/ThomasAndFriends, and Mermaid Man and Barnacle Boy all make brief appearances throughout the poop.

* ChaosOfTheBells: The [[Music/TransSiberianOrchestra Trans-Siberian Orchestra's]] cover of "Carol of the Bells" is used during the battle against the [[spoiler:Black Hiver]].
* CharactersDroppingLikeFlies: [[spoiler: Almost all of the heroes get killed in horrible ways, though it's thankfully undone by the end.]]
* ContinuityNod: Jack uses a lemon to summon the Hiver, and Mermaid Man and Barnacle Boy need a good lawyer. Both are a reference to a previous Poop Mo Bros had made. In it, Squidward is possessed by a demon lemon, and [[spoiler: Mermaid Man and Barnacle Boy drive a sketchy van that has the words, "FREE CANDY" on it.]] Hm, now [[WouldHurtaChild why would they need a lawyer for that?]]
** Also, when [=SpongeBob=]'s sending up letters, WesternAnimation/EdEddNEddy ask for a new [=YouTube=] Poop.
* TheCorruption: [[spoiler: When Black Hiver steals their souls, Fluttershy, Scout, and Soldier are turned into monstrous minions of his.]]

* DarkerAndEdgier: Far more so than previous poops by Mo Bros.
* DeusExMachina: [=SpongeBob=]'s [[spoiler:emergency gear]]. It's even made by Deus X Corp!
* DidYouJustPunchOutCthulhu: Soldier certainly just fired a missile launcher at [[spoiler:Black Hiver]].
-->'''Soldier''': Take your voodoo rabbit ass back to Canada!
** DoNotTauntCthulhu: Soldier immediately regrets it afterwards.
** [[spoiler:Jack, on the other hand, manages to destroy the Black Hiver without any negative repercussions by using a powerful spell.]]

-->'''Jack:''' Crack! I want ''you'' to make it.
-->'''Sally:''' No! (Patchy: ''NO!'') You're being an ass!
-->''[[{{Beat}} (beat)]]''
-->'''Jack:''' ''[[Film/ThreeHundred THIS IS HALLOWEEN!]] (kicks Sally into a pit)'' I'll just make the crack myself!
* DwindlingParty: [[spoiler:Thanks to the Black Hiver, the gang is quickly decimated.]]
* EarnYourHappyEnding: Do they ''ever''.
* EldritchAbomination: [[spoiler: Black Hiver.]] Just to show how nasty this piece of work is, the theme that plays when he's being summoned? The theme from ''Film/TheOmen1976.''
* EliteMook: Patchy the Pirate and the undead nutcracker are this to [[spoiler:Black Hiver. Scout, Soldier and Fluttershy join them (the former two now robots), after death]].

* FreezeFrameBonus: When Jack tells the Mayor on his doorstep not to bother him while he's high on crack, Demoman can be seen for a split-second pointing out that the eye on Jack's door looks like his own missing eye.
* FullFrontalAssault: PlayedForLaughs in the case of [[spoiler: Second Gear [=SpongeBob=]]]; all he was wearing when he TookALevelInBadass was a ridiculous pair of Christmas shoes, a nutcracker hat, his martial arts gloves, and a sprig of mistletoe that fell off at one point.
* GetAHoldOfYourselfMan: Heavy Weapons Guy does this to Ed in "Skellington's Revenge".
-->'''Heavy:''' Put up fists, little man!
* GetOut: When the Mayor tells Jack that taking over Christmas is a bad idea, Jack tells the Mayor to take a hike, find a job in Christmas Land, and to take his weenies with him.
* GoMadFromTheIsolation: After Jack's friends all abandon him and he puts his plan into effect, he is heard talking to them. [[spoiler: Oooh boy, not exactly what you'd think]], check it out:

-->'''Ed''': [[OhCrap AHHHHHHHH!!!]] [[spoiler: DON'T TAKE MY HEAD! DON'T TAKE MY HEAD!]]

* HourOfPower: Spongebob's Emergency Gear, which only lasts for 2 minutes.
* ImAHumanitarian: Patchy the Pirate, of all people.
* IncrediblyLamePun: [=SpongeBob=]'s mistletoe is [[VisualPun an actual toe with rocket fins]]. There's even a collective groan when it's first shown.

* KickTheDog: Jack does it a lot.
* KillTheCutie: [[spoiler: Poor Fluttershy gets her soul stolen and her body is turned into a monster.]]

* MassiveMultiplayerCrossover: The poop features characters from not only ''WesternAnimation/SpongeBobSquarePants'' and ''WesternAnimation/TheNightmareBeforeChristmas'', but also from nearly every property featured in a poop prior to this, including the [[VideoGame/TeamFortress2 RED Team]], [[WesternAnimation/MyLittlePonyFriendshipIsMagic Fluttershy]], WesternAnimation/EdEddNEddy, [[WesternAnimation/CourageTheCowardlyDog Eustace Bagge]], and even WesternAnimation/PhineasAndFerb, among others.
* MoodWhiplash: Two different scenes:
** First, when Mr. Krabs reveals that he wished for ponies.
-->'''Mr. Krabs:''' So I can have their rear ends CUT OFF AND '''MOUNTED OVER ME--'''
-->(Smash cut to Jack's house, filled with cocaine)
-->'''Narrator:''' [[LemonyNarrator Meanwhile, inside my apartment]]…oh, sorry. It just looks like it.
** Second, when Jack first encounters [[spoiler:The Hiver]]
-->'''Jack:''' Help me take over Christmas time!
-->[[spoiler:'''Hiver:''' As you wish...it will be.]]
-->(Fade to black; Patrick suddenly pops up)
-->'''Patrick:''' Just like a genie! (Laughs)
* NoodleIncident: Why do Mermaid Man and Barnacle Boy need a decent lawyer?
** [[spoiler: Black Hiver]] states that the past must be "paid for" at one point.
* OddFriendship: Scout and Fluttershy, the latter always hiding behind him whenever she's scared.

* PaperThinDisguise: Jack shows up in Bikini Bottom disguised as Santa by simply wearing a flat Santa mask. It doesn't hold up for very long.

* RuleOfThree: Jack being called an ass.
--> '''Sally''': ''(after Jack says her vision of his Christmas disaster is splendid and asks her to make him some crack)'' No! You're being an ass!

** When Jack Skellington traps [=SpongeBob=], Patrick, the RED Team, the Eds, and Fluttershy in the Hiver's world, he does so with [[VideoGame/LuigisMansion a painting inside which a key character is trapped]]. [[spoiler: He even sucks them in in a direct recreation of the final boss intro, with Santa as Mario, Jack as King Boo, and the Hiver as Bowser.]]
** [[Film/ThreeHundred "THIS IS HALLOWEEN!"]]
* StandardSnippet: An epic rock version of "Carol of the Bells" plays during the climatic battle.

* SuperMode: [[spoiler: [=SpongeBob's=] Second Gear mode.]]
* SurrealHumor: It's still a Youtube Poop, so this is a given.
* TakeThat: Mo Bros gets in a diss on Mitt Romney.
** Squidward at one point travels in time to "the present" - which depicts the Capitol building with money pouring down and a sign reading "America, Inc.: $$$ > Human Life", all while Moar Krabs appears in the background. The video was uploaded not long after the September 2013 US government shut-down, making the TakeThat all the more poignant.
* ThisIsGonnaSuck:
-->([[spoiler: ''upon the Hiver's awakening'']]) '''Heavy''': I think we need more men...

By the time [=SpongeBob=] wakes back up, [[spoiler: only Ed and Heavy are still alive.]]
* YourSoulIsMine: [[spoiler: Black Hiver's]] specialty.
