History NightmareFuel / SpongebobSquarePants

** This is before mentioning Neptune's Sun, the green moon's land counterpart. It may come as a surprise to some viewers when it appears as a crimson-orange sun towards the end of the episode. It also appears rather intimidating above water as well. Up there, it turns Patchy the Pirate into a caveman.

** As the short progresses, study the backgrounds. The flowers are wilted, the flower patterns in the sky look melted, and the sky is a murky yellow. It's a haunting visual.

** [=SpongeBob=]’s wide-eyed stare from the window at Patrick getting friendly with Squidward is thankfully short, but very much unnerving.

* "SB-129" features Squidward arriving in a realm of nothingness after traveling through the future and the past. He’s alone there with only mild (but creepy) noises heard in the background. The audience can tell there’s something... ''off'' about this place but Squid initially likes it because of its seclusion. Until he says "alone", the word "alone" appears in various fonts, all announced by disembodied voices that start to slowly layer upon each other. This freaks out Squidward to the point where he runs off-camera... except it just loops him back to his starting point. He escapes by pure dumb luck by stomping the ground enough times, which lands him back in the time elevator.

** The audience knows that [=SpongeBob=] isn’t in any danger and that Sandy jumped to conclusions. But when one looks from Sandy's perspective, she was having the time of her life with her best friend, and now he’s suddenly disappeared. The only thing that was left behind was his clothes. The scenario is ParanoiaFuel at its finest, no wonder she had a meltdown.

'''Carl''': The less you know, Eugene, the better.

--> '''Squidward:''' [[BodyHorror It all started when I was born.]]

* The entirety of "Squidtastic Voyage", where [=SpongeBob=] and Patrick [[FantasticVoyagePlot go inside Squidward to get his clarinet reed out of his throat]]. During which they are ''[[{{AndIMustScream}} screwing around with his bodily functions]]'', and, at the end, they end up GROWING inside of him...submarine and all.

-->'''Patrick''': My loyal subjects have deserted me! And it's all because of that ''horrible'' Squidward! This is all his fault! His, his! [[NeverMyFault Not mine! HIS!]] (''[[SanitySlippage a spring seems to pop out of Patrick's head]]'')\\
'''[=SpongeBob=]''': Patrick, what's happened to you?\\
'''Patrick''': I don't know what you mean.\\
'''[=SpongeBob=]''': Um...(''chuckles nervously'') You know, actually, Mr. Krabs is probably wondering where I am, and--\\
'''Patrick''': (''threateningly'') "And" ''what''?\\
'''[=SpongeBob=]''': (''meekly'') And...well, it's...just that...um...you're kinda bein' a...jerk.\\

'''Patrick''': Heheh...I thought you were going to say I was abusing my power...\\
'''[=SpongeBob=]''': ''(Nervous laughter)'' Well, I---\\

---> '''[=SpongeBob=]''': (to Sandy in a weak voice) The more you touch it, the angrier it gets.\\
'''[=Sandy=]''': Oh, that's just crazy talk. HI-YAH!\\

--> '''[=SpongeBob=]''': ''Is there something wrong with me?''

** Plankton's nightmare is also unsettling to watch. He dreams he's being chased by Pearl in a cellar. Pearl catches up to Plankton and eats him, and we can see Plankton in the inside of Pearl's disgusting mouth, banging on her teeth, wanting to be let out. Pearl uses her tongue to knock Plankton down her throat into her stomach, in which Plankton sees [[CallBack his relatives from]] "Plankton's Army", all charred up in the acid. Then we cut to Pearl, who laughs evilly with DramaticThunder in the background. It's horrific for people with a phobia of {{WombLevel}}s to sit through.

--> ''"The song that you ran from is back again.''
--> '''''You wonder if the madness will ever end.'''''"

** Mr. Krabs' worms turning on him when he overworks them. He joins [=SpongeBob=], Patrick and Sandy in their sleigh and the worms chase them down. It’s genuinely unnerving to see Gary struggle to pull the sleigh with all the excess weight, everyone pleading for him to go faster and the vicious worms gaining on them. When they’re cornered, ''everyone'' screams in terror as they’re about to be mauled. Luckily, Gary scares the worms off, but still.

--> "I CAN SEE EVERYTHING!!!"

--> "Focus on the road. There is nothing but the road."

---> "We're sorry. The person you are calling, [=SpongeBob SquarePants=], has been disconnected or is no longer in service."[[note]]If you don't get it, it's a way of saying that [=SpongeBob=] isn't there anymore. Saying he's been disconnected is a way of saying that his identity has been forgotten. Pretty disturbing...[[/note]]

-->'''[=SpongeBob=]''': No, Cuddle E. Hugs, no!\\
'''Cuddle E. Hugs''': '''[[NightmareFace YES, SPONGEBOB SQUAREPANTS,]] ''YES!!'''''

--->'''Patrick's intestines''': May I borrow a cup of squid squeezings?

-->'''Mrs. Puff''': You... let them out of the freezer once they were better... right?\\
'''Krabs''': Huh? I suppose ''someone'' let them out... ''eventually''.

* If you have (or have had) any [=SpongeBob=] VHS tapes or [=DVDs=] released sometime between 2002-2009, you may remember seeing classic promos for [=SpongeBob=] (as well as other Nickelodeon shows) [=DVDs=]. One particular promo you might recall seeing was known as "The Attack of the [=SpongeBob=] [=DVDs=]". The entire promo mentioned many of the [=DVDs=] released or scheduled for release around this time, and showed clips from episodes such as "Atlantis [=SquarePantis=]" and "Dunces and Dragons", and portrayed all of them in a massively frightening manner, accompanied by horrifying orchestral music and an overly dramatic narrator. Though there is a small funny moment when the music stops when the famous clip of Squidward screaming in his tub appears, and there is an adorable moment with happy music showing adorable clips of [=SpongeBob=] and his friends having fun, in which a different narrator with a much calmer voice states the [=DVDs=] aren’t really frightening, the majority of the commercial is, without question, pure nightmare fuel.

* [[https://www.youtube.com/watch?v=9X5ApsYq5fQ#t=8m40s This music]]. It combines an [[NightmareFuel atonal]] creepy music box with quiet PsychoStrings, an off feeling, and ends in a ScareChord. It's used to signify insanity. The name of the track would be [[https://www.youtube.com/watch?v=rBQ7JT-HaKc "Unease"]].

* [[https://m.youtube.com/watch?v=-aLclz1ltoY This educational short from 2005 called "The Endless Summer"]], which played as part of ''Earth to America'', a television special from 2005 that tries to raise awareness regarding human damage to the environment (specifically global warming).

* The ''Nautical Nonsense and Sponge Buddies'' DVD has a special feature called "Backstage Pants", which is a series of mini-feaurettes with the cast and crew talking about the making of the show, certain episodes, or other little anecodtes. Most of them are fun and charming. However, there's one among the bunch that's surpisingly unnerving. It features Creator/TomKenny talking about the closest thing he ever smelled to [[Recap/SpongeBobSquarePantsS2E2SomethingSmellsBossyBoots SpongeBob's gross sundae]] was some strange neighbors he once had while living in an apartment who, for whatever reason, caused you to get hit with a weird smell. He notes with an increasing look of horror in his eyes that no one ever found out who they were or what they were doing. Then he whispers "Maybe it was the Hash-Slinging Slasher..." before letting out a '''blood-curling scream'''.

* ''Ship o Ghouls'', a flash game based on the episode; "Shanghaied", where you have to help SpongeBob escape from the Flying Dutchman's ship before all the water dries up. It could give you anxiety since you have to apparently mash the down arrow key to go inside the thin pipes.

** SpongeBob's death animation when he fails to get inside the tube before the water dried up. The poor Sponge gets dried up and shrinks, unable to do anything.
*** The game over screen looks similar to the original ending of Shanghaied, as SpongeBob is stuck in the Flying Dutchman's plate and he is ''holding a fork and knife, ready to eat him.''
*** During gameplay, a candy will randomly appear on top of the screen. If you click on it, you will interact with a sudden shot of SpongeBob making a scary face.

*** [[https://www.youtube.com/watch?v=XKxIrIXQCQo "In the Crypt"]] is another nightmarish track that plays during The Flying Dutchman's rant about Halloween costumes based on him. The OminousPipeOrgan just sounds so... ''Eerie...''

* The scene in "[=SpongeBob=] Meets The Strangler" where [=SpongeBob=] gets ''really'' pointy cleats to jump on the Strangler's shoulders to go to a window, but of course misses and lands straight into the strangler's waiting [[EyeScream eyes]]. It's not displayed realistically, but the image of his feet sticking out of the Strangler's sockets coupled with his screams makes for a... memorable image.

* The moment in "Plankton!" when [=SpongeBob=] rolls his eyes all the way back in his head to see that the titular copepod has hijacked his brain. Then Plankton resumes control and lets out an EvilLaugh, while Sponge's eyes are still [[BlankWhiteEyes rolled over white]]. No wonder Squidward turns pale and passes out.

Then he whispers "Maybe it was the Hash-Slinging Slasher..." before letting out a '''blood-curling scream'''.
* In the video games ''Battle for Bikini Bottom'' and ''[=SpongeBob=]'s Truth or Square'' in Rock Bottom. The music there is HORRIFYING. It's also not helped by the fact, that those [[DemonicSpiders Sleepy Robots]] are both REALLY ANNOYING AND IN THE WAY but also VERY HARD TO KILL!! And it will hurt you very easily. Especially with Sandy. Rock Bottom in BFBB is also one of the most complicated places in the game.

* Speaking of creepy unnerving music, there's also [[https://www.youtube.com/watch?v=EuDmzOQFy1A this music]] called Shock, which usually plays when characters go insane especially in Squid's Day Off or Earworm. Both are creepy enough episodes, but this music adds to the creepiness factor.

** The short goes like this. With summer approaching, Mr. Krabs uses the exhaust from a car to make the summer hotter (encouraging global warming). This is a ploy to get more customers to attend the new pool. However, [=SpongeBob=] thinks that an "endless summer" sounds fun, and uses more cars and other greenhouse emitters to speed up the process. The customers 'attending' the pool was just a HopeSpot, as the entirety of Bikini Bottom, [[OOCIsSeriousBusiness even Patrick]], realize that Bikini Bottom is too hot to live in and move to colder climates. The short has NoEnding (or DownerEnding, depending on who you ask) and simply concludes with the water in Mr. Krabs's pool drying up and [=SpongeBob=] smacking into the bottom when he attempts a dive.

* ''[=SpongeBob=] Saves the Day!'' is a pretty fun [=HTML5=] game, but if you look in the game's files, you can find [[https://tcrf.net/File:SSTD_yummer.png this creepy little bugger,]] and people call him Yummer. He's a truly unnerving character, especially with his NightmareFace. Did he ''really'' need to be in a ''[=SpongeBob=]'' game?

* "The Ghost of Plankton" features Plankton attempting to turn himself into a ghost in order to enter the Krusty Krab and steal the formula. He creates a machine that does just this, which painfully extracts his spirit from his body, leaving it a withered husk. In essence, Plankton killed himself just to get the formula.
* "Boss For A Day" has the scene where, in an effort to help Squidward keep customers happy, [=SpongeBob=] places a training smiling helmet on Squidward's head to have him smile for them. Though it doesn't last long, it's still very painful to watch, with his creepy smile not helping at all. The customer looks justifiably creeped out by this.

** The ending. Everyone in the Krusty Krab ends up getting sick after all (though due to circumstances unrelated to the clam flu that prompted the kwarantine). All the diseases shown, such as Squidward's "grease gout", [=SpongeBob's=] "moldy measles", and ''especially'' Krabs' "whole shebang" are shown through really gross close-ups. The health inspector runs away in terror and the whole thing plays out like a zombie movie.

** Fortunately, this scene was removed after November 2019, and replaced with an image of a baby Squidward pooping his diaper loudly. According to Paloian, Nick's Standards and Practices ordered the "Squidward's Suicide" scene to be replaced with the baby one. However, the original version is still airing in Canada.

** The [[OminousMusicBoxTune creepy song]], titled [[https://www.youtube.com/watch?v=482CpyWqH6U "Ghost Child"]], that plays when [=SpongeBob=] nervously washes dishes at the beginning of the episode. Thankfully, it was only a short snippet of the full track.

** Also, extra credits go here for Creator/TomKenny's [[SugarWiki/HeReallyCanAct absolutely terrifying performance]] during this scene, since with just the delivery of the line "I've been WAITING for you, Patrick!", he manages to amazingly turn [=SpongeBbob=] from a happy-go-lucky sea sponge to a psychopathic lunatic!
* The entirety of "Squidtastic Voyage", where [=SpongeBob=] and Patrick [[FantasticVoyagePlot go inside Squidward to get his clarinet reed out of his throat]]. During which they are ''[[{{AndIMustScream}} screwing around with his bodily functions]]'' and at the end they end up GROWING inside of him...submarine and all.
** The scene where they went into Squidward's brain! They messed around with his brain and made him spaz out against his will. One [=YouTube=] commenter actually said this episode made her paranoid that her brain hurt due to someone being in it. However, the brain cannot feel pain, so she'd be fine, but still, this episode can cause ParanoiaFuel!

** Ick is a real fish disease. The best way to explain it is that it's the equivalent of a flea to dogs and cats. It reproduces like crazy and feeds on blood and dead skin cells. However, it doesn't manifest itself as green fuzz, rather, it looks like somebody sprinkled salt on the fish.
*** It becomes more disturbing if you've ever dealt with Ich in aquarium fish. Ick is extremely contagious among fish because it has a fast breeding cycle and the fact that once the parasite encysts, it can stick to just about anything in the tank. If someone doesn't treat ick, it's 100% fatal among fish.
* "Money Talks". Mr. Krabs wishes he could talk to money, so the Flying Dutchman grants him that ability. However, the money wants to be spent, and Mr. Krabs, having a MoneyFetish, refuses to do so. During the night, the money moan, "''Speeeeeennnnnnd uuuuuuuuusssss...''" in the creepiest tone possible.

* "A Flea in Her Dome": In this episode Sandy brings a flea back from Texas. There's only one flea at first, but then it multiplies... and multiplies... until [[ExplosiveBreeder there's a huge WAVE of fleas inside the tree dome]].

* The scene in "[=SpongeBob=] Meets The Strangler" where [=SpongeBob=] gets ''really'' pointy cleats to jump on the Strangler's shoulders to go to a window, but of course misses and lands straight into the strangler's waiting [[EyeScream eyes]]. Its not displayed realistically naturally, but the image of his feet sticking out of the Strangler's sockets coupled with his screams makes for a... memorable image.

** His plan to strangle [=SpongeBob=] does make the atmosphere darker despite him being otherwise the recipient of all the nightmarish things that occur in the episode.

* "Doing Time", where Ms. Puff is blamed for [=SpongeBob=]'s inept driving and winds up in jail, which to her is a respite from the hell that is her normal life with [=SpongeBob=]. But alas this respite is not to last, as he and Patrick, repeatedly try to rescue her, but instead make the guards think she's insane and throw her in an isolation cell. In the cell, she goes insane for real and starts hallucinating that the padded walls are made of sponge, and that each has [=SpongeBob=]'s laughing face on it. Then she starts hallucinating the beginning of the episode over and over, each time a little different and a little weirder. It turns out that the the entire jail episode was just a hallucination Mrs. Puff had ''while still falling off the cliff.'' The episode ends with her giving up on deciding what's real and what's not and resigning herself to insanity.

* The live-action gorilla, emerging from his animated Patrick suit in "I Had An Accident" and proceeding to [[NoHoldsBarredBeatdown beat the snot out of Patrick and Sandy]]. He even [[HalfTheManHeUsedToBe tears [=SpongeBob=] in half!]] Thankfully, [[NightmareRetardant he becomes less scary when he realizes that he is underwater]] (albeit the close-up to his eyes can be [[GrossUpCloseUp quite startling]] [[NightmareRetardant and that he has no idea what's he doing here in the first place, summoning George the horse and hopping onto him]] [[RidingintotheSunset as they run off into the sunset]].

-->'''"Grass":''' [Earth-shaking uproar of laughter]
-->'''Mr. Krabs:''' ...[[OhCrap Uh oh.]]

* Man. the whole concept of "Whirly Brains", and the fact that almost all of those who had a Whirly Brain got it kidnapped by a grumpy old fish. Imagine getting your brain kidnapped and not being to able find it. Hell, imagine turning your brain into a toy and using it to terrorize everyone!

* The live-action gorilla, emerging from his animated Patrick suit in "I Had An Accident" and proceeding to [[NoHoldsBarredBeatdown beat the snot out of Patrick and Sandy]]. He even [[HalfTheManHeUsedToBe tears [=SpongeBob=] in half!]] Thankfully, [[NightmareRetardant he becomes less scary when he realizes that he is underwater]] (albeit the close-up to his eyes can be [[SurpriseCreepy quite startling]] [[NightmareRetardant and that he has no idea what's he doing here in the first place, summoning George the horse and hopping onto him]] [[RidingintotheSunset as they run off into the sunset]].

* In "Enchanted Tiki Dreams", while Squidward is singing "Squidward's Tiki Land", as he sings "Don't matter to me 'cause, 'cause I'm crazy, man!", he suddenly takes off his glasses and juts his head forward at the screen, all while having [[WingdingEyes bizarre-looking eyes]] and shakes his head at one point. It only happens for a few seconds, but it can [[SurpriseCreepy be surprisingly creepy]] for those not expecting it.

** This is before mentioning Neptune's Sun, the green moon's land counterpart. It may come as a [[SurpriseCreepy surprise]] to some viewers when it appears as a crimson-orange sun towards the end of the episode. It also appears rather intimidating above water as well. Up there, it turns Patchy the Pirate into a caveman.

** The callous way [=SpongeBob=] treats Gary throughout the episode is also worth mentioning. It is ''incredibly'' out of character for [=SpongeBob=], who is normally so nurturing towards Gary, to outright ''scream'' at the poor snail for ''trying to protect his family!'' Why didn't [=SpongeBob=] heed the pet trader's warning??

* In "Bubble Troubles", [=SpongeBob=] and Patrick destroy the air supply to Sandy's tree dome. As the episode progresses, Sandy's suit is running out of oxygen, and she loses her mind in an unnervingly realistic portrayal of oxygen deprivation.

** Patrick possibly makes this Nightmare Retardant:
** "I'm no doctor, but I don't think squirrels are supposed to be blue!"

* In "Toy Store of Doom," [=SpongeBob=] and Patrick spend the day at a new toy store, and decide to stay inside after it closes. When the power cuts out, [=SpongeBob=] and Patrick are terrified, and believe that the toys are coming to life and trying to "get them." While it should sound rather silly to the viewer, we see it from their POV, where they both begin to see the cute and cuddly toys slowly turn [[NightmareFace hideous and evil.]] And if you thought that was bad, just wait until they bump into a shelf, and get [[https://static.wikia.nocookie.net/spongebob/images/a/a9/Toy_Store_of_Doom_134.png/revision/latest/scale-to-width-down/1000?cb=20191109084629 buried under a pile of them!]] Not to mention the way we're [[JumpScare subjected to]] [[ScareChord that image.]]
