While the series runs primarily on RuleOfFunny, some of the attempts [[GoneHorriblyWrong went in]] [[NightmareFuel a totally different direction]].

Remember, this page is for describing general sources of NightmareFuel.
----
* ''HomestarRunner'' no doubt intended to capture this intentionally with Marshie. The Homestar Runner Wiki describes Marshie as "the genuinely alarming mascot for Fluffy Puff Marshmallows", and several cartoons have featured fake commercials starring Marshie that are downright creepy, featuring "non-sequitur rantings, disturbing close-ups, inappropriate sound effects, faintly desperate pleas and even a behind-the-scenes nervous breakdown". Strong Bad put it best: "I really think those Marshie commercials ought to be rated NC-17" (Needlessly Creepy Times 17).
* Then there's Gel-arshie, the mascot for a gelatin dessert made by the Fluffy-Puff company. Gel-arshie is a translucent, bright red version of Marshie with a distorted voice and a floating ''visible brain'' in his center.
-->'''Gel-arshie''': I'M AN ABOMINATION! And I'm coming to your house after school...
* Then, there's episode 5 of ''Strong Bad's Cool Game for Attractive People,'' in which Gel-arshie is part of Strong Bad's party. Creepy Mascot + More screen time = New levels of Nightmare Fuel. Even worse, he's REQUIRED in order to beat the final boss.
-->'''Gel-arshie''': Hey kids! I'm Gel-Arshie and I'm in your house! You tired old snacks can-AHH! WHAT HAVE YOU DONE TO MY LEGS?!
** You summon him by rigging the villain to shoot point-giving fruit instead of ammo. This results in a KillScreen that brings Gel-arshie ''into the real world''. It even parodies TheRing when he jerks forward, causing Strong Bad to scream and fall back.
** And really, who can forget his other JumpScare moments? Such as when he's used to turn a pool into gelatin and Strong Bad sings the commercial jingle, only for-
-->'''Gel-arshie''': DON'T SING MY SONG!
-->'''Strong Bad''': *screams*
* Marshie's counterpart in the "Old-Timey" AlternateUniverse, Mr. Shmallow, is ''slightly'' less distressing ("Look lively. ''Look lively!''"). At the end of the "Fluffy-Puff Air-Puffed Sugar Delights" commercial, Homestar comments, "That monster's gonna give me nightmares."
* What may take the cake on Marshie's general horror is an easter egg from Strong Bad Email 149- Marshie in vapor form.
-->'''Vapor Marshie''': Youuuuu can't destroyyyy meeee...
* Since Homestar Runner has such a basis in the creators' childhood, it's not surprising that some within-series examples of this would crop up. A young Strong Sad was apparently terrified of his neighbor, Senor Cardgage ("He was extremely sketchy and gave me nightmares!"), and Strong Bad gets "the jibblies" at the sight of That Horrible Painting That's Been in Strong Mad's Closet Ever Since We Were Little ("Come on in heeeeeeeere....."), as well as The Little Chef Guy. Homsar himself is a rather unnerving character, seeing as he is a mutated, stunted in-universe parody of Homestar Runner. Though really, Homsar's meant to be that. He was made by a misspelling of "Homestar" in Sbemail #2, so it'd make perfect sense that he'd be weird.
** Speaking of That Horrible Painting, the 2007 [[HalloweenSpecial Halloween episode]], "Jibblies 2" certainly did it for many viewers. The premise is genuinely creepy, what with everyone being hypnotized by the painting, Strong Bad wildly convulsing and bouncing all over the room and up against the ceiling, and finally [[spoiler:Homestar entering the Horrible Painting itself - though the fact that the demon finally has a friend and will no longer be evil (and Homestar's adorable [[Series/TheAdventuresOfPeteAndPete Artie The Strongest Man In The World]] costume) softens the blow a bit.]] The Brothers Chaps even included a disclaimer stating the episode might be too much for younger fans.
*** Though easter eggs literally save it, especially Homsar's.
---> '''PAINTING:''' Come on in heeeere!
---> '''HOMSAR:''' Iiii'm a touchy-feely holic!
---> '''PAINTING:''' Jibblie jibblie jibblie!
*** There's another easter egg saving the special.
---> '''STRONG SAD:''' "Original" and "Horror movies"? [[NoFourthWall Not these days...]]
* The Drive-Thru Whale is a surreal drive-thru speaker known for showing up out of nowhere and spouting crackly non-sequiturs, usually revolving around self-mutilation (''"Sever your leg, please. It's the greatest day."''), with the implication that it actually ''eats'' [[TooDumbToLive anyone who actually complies with its requests]]. If it weren't funny as hell, it would be terrifying.
** The first episode of ''Strong Bad's Cool Game for Attractive People,'' "Homestar Ruiner", not only features the Drive-Thru Whale but gives it more dialogue than all of its previous appearances combined, mixing the Whale's typical hilarious nonsense ("Would you like monkeys with that?") with a dash of ParanoiaFuel ("Please smile for the Blubb-o's satellite camera!") and at least one insinuation of fiery destruction ("When the End Times come, we will all dance the Conga of the Apocalypse!").
*** Well, more like {{Foreshadowing}}, when you get to the "end times" of the game and you have to kick everyone out by inciting a conga line.
* And in the Strong Bad Email "licensed", Papa Cardgage's Puddin' Patch and the Strong Bad jelly pop.
** The fact that Senor Cardgage sings both call ''and'' response to his song is somehow immensely comforting, as it suggests that he is alone in the building. Or maybe that's his MadnessMantra...''Yikes!''
--->'''Where is Tompkins? [[ImAHumanitarian Where is coleslaw?]] Here I am...'''
*** There's a body outline in chalk nearby.
*** And there's a painting of a more realistic Senor Cardgage on the side of the building as well, along with the phrase '''''[[FridgeHorror "I take kids."]]'''''
** The email ends when Homestar turns up with ''shards of glass embedded in his bleeding face''.
*** Of course, that mess was ''still'' his best birthday ever. So either everything else was ''f**king awesome'', or Homestar has some seriously crappy birthdays.
* ''[[http://www.homestarrunner.com/trudgemank.html Trudgemank]]'' is saved from being absolute Nightmare Fuel only by the timely intervention of Peacey P.
* Also, [[http://homestarrunner.com/main25.html Main Page #25]] not only features another appearance by Marshie, but also features a somewhat disturbing appearance by a [[UncannyValley seriously off]] Homestar Runner puppet. There is something strangely frightening about the ensuing exchange, especially how Not Homestar's mouth doesn't move:
-->Not Homestar: ''"The store."''
-->Homestar: ''"Who are you?"''
-->Not Homestar: ''"Well, I am the exact same."''
** Shark-tooth Bubs has an equally unnerving quality to him.
* The Strong Bad E-mail [[http://www.homestarrunner.com/sbemail148.html "disconnected"]] features the not-quite regenerated versions of "Head Bad" and "Strong Body". "Euw! Go away, Head-Nub and Nub-Head!"
* The main page shown above features [[http://www.homestarrunner.com/main7.html Pom-Pom as a ghost, and Homestar and Strong Bad as zombies]]. Defused somewhat when Strong Bad's head falls off and rolls away.
--->'''Zombie Strong-Bad:''' "I come back from the dead, to ta-* head starts leaning* whoa-oa! * head rolls away* holy craaaap..."
** And when you roll your cursor over "Toons," worms come out of H* R's mouth * shudder*
* Then, there's Marshie's bit at the beginning of [[http://www.homestarrunner.com/sbemail159.html "retirement"]]...
--> "Just e-mail who you think done it on a 3x5 postcard, stick a Fluffy Puff on each corner, and ''just walk away, Mother...''"
* And don't forget Sweet Puttin' Cakes, the very deranged miniature golf course from "mini-golf". "Every bit as messed up as the cartoon on which it's based", indeed.
* The sbemail [[SurrealHorror "Virus"]].
* The Poopsmith ''hissing'' during a particular Halloween special. Also, Strong Bad's pickled, talking corpse in the sbemail "[[http://www.homestarrunner.com/sbemail168.html Your Funeral.]]"
--> Zombie Strong Bad: Sorry, everybody. Funeral's over. Not even death can stop me from stopping my leotarded brother prancing around in my honor.
--> Strong Sad: But you never got to see my Chaup au Fan!
--> Zombie Strong Bad: You keep your chappy thong to yourself, mister.
* [[http://www.hrwiki.org/w/images/c/cf/Dongrel.PNG The Dongrel torso in ''VideoGame/ThyDungeonman III''.]] That thing should go back to the ''SilentHill'' universe where it belongs.
* The Powered by the Cheat music video "Crystal Fortress" features some darn creepy imagery (The unicorn horns sprouting out of stuff-- {{Squick}}...).
* In Punkin Show, there was the Homestar pumpkin. Not quite high octane, but Homestar did mention that it may be unsuitable to children.
* The end of "being mean" features Strong Bad's drawing of a nasty-looking shark. While the design can be a bit [[NightmareRetardant cheap in appearance]], it expresses a desire to eat the sender's kids.
* Doomy Tales of the Macabre, while mostly a BlackComedy, did cross the line a few times. Strong Mad [[spoiler: eating The Cheat]], the King of Town drowning to death (though he enjoyed it), Pom Pom exploding, Bubs' severed head, ONION BUBS TALKING, Homestar gaining too many knees and, of course, the UncannyValley [[spoiler:human hands]]. Strong Sad's costume and the NothingIsScarier intro did not help.
** It's kind of nullified by (a) the awesome costumes (STRONGBADAS[[MajorasMask SKULLKID]]OMG) and (b) everyone's various reactions to their deaths, some of which are hilarious.
*** Nullified a bit when Strong Bad cuts in to say that's actually how they ''bathe'' The Cheat.
---> '''Strong Bad:''' That's not macab-er! Strong Mad eats the Cheat like, four times a day! How do you think we give him baths?
** [[http://www.hrwiki.org/wiki/The_Legend_of_Zelda What a totally unfrightening Zelda moon...]] ''I'm terrified...''
** Not to mention Strong Sad, one of the ''nicer'' characters in the show, is fantasizing about ''killing'' his friends because [[DisproportionateRetribution they didn't come to his party]]! Talk about ''serious'' HiddenDepths!
* At the end of [[http://homestarrunner.com/xmas10.html this Decemberween toon]], we see Homsar [[spoiler: ''half-dead in a snowbank.'']]
** His expression helped *add to the shock value* a lot.
** And then, to compensate for their lack of a Halloween toon that year, The Brothers Chaps released a cartoon where all of the main characters appeared, "got their weens mixed up" and dressed up in Christmas-related costumes. ''[[FridgeHorror All except Homsar]]''.
*** Nullified by the fact that one was JUST the costumes part. The costumes come at the end of every Halloween toon, and Homsar usually only appeared if you activate his easter egg during the toon. Since there is no toon, [[http://tvtropes.org/pmwiki/pmwiki.php/Main/FridgeBrilliance there is no easter egg, meaning no Homsar.]]
* In "Bug in Mouth Disease", Homestar goes to see Bubs about his swallowed bug problem. Before he arrives, there's a shot of Bubs burning a manilla envelope labeled "Exhibit A", which he quickly hides when Homestar shows up. After "examining" him, Bubs tells Homestar that he has no pancreas, but "luckily", he happens to have a fresh one on him- inside a cooler labeled "Exhibit B". It's not hard to figure out what's going on here: ''Bubs is involved in organ trafficking''.
** The SCG4AP series confirms this.
* There's also Strong Bad's [[LaughingMad little psychotic laughing fit]] at the end of "isp". Not helped is that the camera jump cuts closer to his face as he laughs.
* The voice actor for Blue Laser Commander is revealed in one cartoon. Let's just say he looks like a pastel green [[Series/TalesFromTheCrypt Crypt-Keeper]] with bloodshot eyes.
* The King of Town is both an ExtremeOmnivore and a BigEater. He employs the Poopsmith for reasons he doesn't want to say.
** And he's apparently able to eat ''anything''. [[FridgeHorror Think about it]].
*** Well he did seem excited to go to Transylvania after hearing from Strong Bad that they eat puppies for breakfast there.
*** And according to one Halloween special, he's capable of ''eating holidays''. He's a borderline EldritchAbomination!
* An Easter egg in "Hremail2000" shows Strong Bad walking around in what looks like Strong Sad's feet which have torn edges and make a squishy sound as he walks in them. What's more, he refers to them as "foot pelts", thus giving the impression that he's wearing Strong Sad's actual feet. NegativeContinuity saves it in the end.
* Near the end of "Homestaraloween(sic?) Party" Strong Sad just flickers the flashlight on and off, continuously, until the end of the toon, all while spooky music is playing. It's just...creepy...
** [[WildMassGuess He was the only one still at the area of the party, and still with the flashlight. It'd probably be a antic of boredom.]]
* There's a DVD Game on Everything Else, Volume 2 that's HONF. You play as Blue Laser, and both the wrong choices kill you. One zaps him to death and you see his skeleton, the other slices him in half and ''you can see his insides''.
* Regarding the Easter egg on imaginary: trying to imagine what Pumpy Clumpy looks like.
** From that same sbemail, Coach Z shows us his imaginary friend, "Real Life Mister Blancaster Next Door." He's the most humanoid of the imaginary friends, and all he does is shiver and moan. It's really kind of unnerving, and reeks of FridgeHorror.
* Mancuso's Older Brother from [[http://www.homestarrunner.com/costumecommercial.html the first 2008 Halloween toon]] could count; the fact that he has a less-cartoony design than the regulars probably doesn't help matters.
* At the end of the "Grumblecakes" music video, Strong Bad makes a rather unnerving grin that just has to be a SlasherSmile.
* In the remake of "[[http://www.homestarrunner.com/wheremyhat.html Where My Hat is at?]]", there's a scene where Homestar finds Strong Sad in a pool, and it seems that he was being drowned mafia-style by Strong Bad and The Cheat. Never mind the highly disturbing punishment, which is far more cruel than anything else Strong Bad has ever done to his little brother, but his eyes are also sunken in and ''bloodshot'' from being submerged so long. Yikes!
* In the normally cheery world of Homestar Runner, it's incredibly unnerving when the series suddenly and abruptly switches tone. Such an occurrence happens in one of the Easter eggs available at the end of the Sbemail "[[http://www.homestarrunner.com/sbemail170.html rough copy]]". Homestar is shown sitting alone in a darkened room, apparently despondent. Nothing but the wind is heard for quite a while. Homestar eventually sighs and [[OverusedRunningGag wearily mutters "DNA evidence..."]] This is part of a series of teasers for a later (and thankfully humorous) cartoon.
* Strong Sad keeps [[http://www.homestarrunner.com/sadjournal/index.html a secret blog]] that was updated from 2002 to 2005, and surprisingly, it's genuinely sad. It's spooky from the moment you enter, with a drab grey color scheme, the depressing title "Strong Sad's Litany of Crushed Hopes and Dreams", and his creepy black-and-white profile picture (currently Bull Shannon from ''NightCourt'', with previous pictures including Count Orlok from ''Film/{{Nosferatu}}'' and a freaky caricature of Edgar Allen Poe). Some of the content is pretty funny, as Strong Sad has a dry sense of humor and leads a very strange life, but most of it is shockingly dark for ''Homestar'': Strong Sad is shown to be pitifully lonely, nearly emotionless, severely abused, obsessed with counting, and prone to wasting hours of his time on pointless tasks, and he has bizarre and eclectic tastes, no talent in anything, and no drive to ''do'' anything. Given how, in the main Toons, Strong Sad's depression is usually PlayedForLaughs, it's [[MoodWhiplash very upsetting]] to see it portrayed as the awful living hell that it [[RealityEnsues really is]].
** [[http://www.homestarrunner.com/sadjournal/vday.swf This]] is one of the things you can access from Strong Sad's blog.
* Sickly Sam's Big Outing has a scene after the flower scene where the film "glitches" up. It then cuts to an alternative ending whereas they put The Homestar Runner and Old-Timey Marizpan in the glue factory as well. It's out of nowhere, and thank goodness it's not the real ending.
* The SBEmail "current status" begins with a shot of Strong Bad's computer and no sound for the first few seconds, then the sound of running footsteps closer, which turn out to be coming from Strong Bad on the run for a reason he "really can't explain." [[NightmareRetardant It turns out he's running from Coach Z and Bubs because he somehow managed to switch their heads.]]
