10	Being a supernatural show in which the premise involves two kids who are friends with Death itself, ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' not only has a large number of NightmareFuel, but also a great deal of BlackComedy and [[GrossOutShow gross-out humor]].

15	[[folder:In general]]
16	* ''[[https://www.youtube.com/watch?v=vVTyJ3Yecx0 Trepanation of the Skull and You]]'', the old short that Maxwell Atoms made in college, starring early versions of Billy and Mandy. It's been described as being like something out of a Main/{{Creepypasta}}, and it definitely shows. It involves Mandy drilling Billy's head to make room for his brain, complete with [[{{Gorn}} blood coming out of his head]]. Mandy's personality here isn't much better because while Show Mandy was more [[EmotionlessGirl harsh and cold]], Short Mandy is the complete opposite being [[DissonantSerenity deceptively cheerful]] and a little [[TroublingUnchildlikeBehavior too happy to drill Billy's head]].
17	* The intro for Grim Adventures when it became its own series, when Billy and Mandy are brought from skeleton to muscle to skin.
18	* The ending credits for the beginning seasons. Accompanied by some utterly eerie and evil-sounding music, it first shows flames with the main characters as Tarot cards. Then as the flames begin vanishing and the credits come to a close, there's a very creepy VoiceOfTheLegion.
19	** The creepiness factor [[NightmareRetardant dampens though]] if one reverses the audio, revealing it to be Maxwell Atoms saying "No, no, this is the end of the show! [[LampshadeHanging You're watching it backwards]]!"
20	* Mandy smiling. Not her evil smiles, but a genuine grin. Considering her character, it's extremely unsettling.
21	* Mandy in general. This girl even scares the Grim Reaper! One example is when she demands Grim to help her close Pandora's Box.
22	--> '''Mandy:''' You're going to help me fix this mess, and you're going to do it now!
23	--> '''Grim:''' And why should I do that?
24	--> '''Mandy:''' You're going to do it, or so help me, [[VoiceOfTheLegion I will pull your stupid cloak through your eyes, and]] ''[[VoiceOfTheLegion use it as reins to ride your bony butt back to the darkest pits of the underworld]] '''[[VoiceOfTheLegion FROM WHENCE YOU CAME!!]]'''''
25	--> '''Grim:''' Okay, okay! Sorry I asked! [quietly] You little psychopath.
26	** Even worse is the fact, when she tells this to Grim, Mandy shows [[NightmareFace a exaggerately demonic face]], with [[MoreTeethThanTheOsmondFamily a pair of shark teeth rows]], plus the entire stadium on hellfire to date.
27	** Also, to date, in ''EVERY'' moment where Mandy appears, the things turn DarkerAndEdgier.
28	* In one of Mandy's intro quotes, she just walks on screen, points at the viewers, and lets out a ''demonic screech''. This scene, or at least one like it, was actually a ShoutOut to the alien screech from ''Film/InvasionOfTheBodySnatchers''.
29	** In another, she says "Evil. Pure and simple from the 8th dimension". And after she says that, she pulls her face off, revealing her as a purple skull-like creature and hisses at the viewers. This is a reference to ''Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension''.
30	** One of the scariest ends in a JumpScare. "No matter how bad it is, it's about to get worse." Cue JumpScare
31	** The one before the episode "The Love That Dare Not Speak Its Name"; she just simply walks in, looks at the camera and ominously says, “Things are not always as they seem”. What makes it creepy? ''[[VocalDissonance She says it in]] '''[[VocalDissonance Grim’s]]''' [[VocalDissonance voice.]]''
32	* Nergal Jr. You don't want to mess with that kid. His "true form" is truly horrifying. There's also the shot of his tentacles coming out from weird fleshy holes in his back and head.
33	** The "green-eyed kid" form he is usually seen on the show in ''[[YouCannotGraspTheTrueForm isn't even his own original form]]'', he ''stole'' it from the first person he met he met when he rose from the core of the planet. His original form is never seen by the viewer, but the original green-eyed kid is unfortunate to, and is outright terrified of it. [[BlatantLies The best part?]] The original green-eyed kid is '''''[[WhatHappenedToTheMouse never]]''''' ''[[FridgeHorror heard of in the show again]].''
34	* That creepy anthropomorphic crow [[NoIndoorVoice without any indoor voice]] that narrates some episodes.
35	-->"Do not cry for him. DO NOT CRY!!!!!!"
36	[[/folder]]

38	[[folder:Grim and Evil shorts]]
39	* "Billy's Growth Spurt" has Billy drink a potion that inadvertently gets him a pimple on his back which turns into a creature that slowly turns into a clone of him who is dubbed Yupp Yupp. And when he eats Yupp Yupp's remains, it's implied Yupp Yupp ''became'' him.
40	* Billy's nightmare of New Mandy coming after him with a spatula in "Tickle Me Mandy". The random detailed close-ups of Billy's face do not help.
41	* The ending of "Tastes Like Chicken", in which we find out that [[ImAHumanitarian while Mandy didn't actually eat everyone else, she did indeed eat Irwin]]. The title card for the segment is also pretty unsettling, as it shows a grotesque drawing of Mandy cannibalizing another kid.
42	* "A Dumb Wish", in which Mandy wishes that everyone in the world except her would go away.
43	-->''"Perfect."''
44	** There's also the matter of Mandy, prior to that wish, managing to scream [[BigWordShout "STOP!"]] loud enough to ''[[TimeStandsStill stop time itself]]''.
45	* The very end of "Something Stupid This Way Comes". After Nergal hears that Billy and Mandy enslaved and forced Grim into being their friend, he gets the idea of turning everyone into Nergalings. "[[TheFourthWallWillNotProtectYou And you. You will be my closest, most bestest friend of all!]]"
46	** And even worse? The whole ending of this episode in general would've probably never happened if Grim had just kept his big mouth shut! NiceJobBreakingItHero.
47	* The ending of "Get Out of My Head!", where it's revealed that Mandy possessed Billy's cat Milkshakes to get back at him for what he did with her body, complete with a ExorcistHead as the music turns sinister. The episode pans out with a ShadowDiscretionShot as the sounds of tearing and Billy screaming and pleading with her is heard.
48	-->'''Mandy''': You know, Billy? You can pick your friends (''shink!'') and you can pick your nose (''shink!''), [[BreadEggsBreadedEggs but you can't pick your]] ''[[BreadEggsBreadedEggs friend's]]'' [[BreadEggsBreadedEggs nose...]] (''shink!'')
49	** If you listen closely at the end, you can hear Billy scream, “My eyes!”, which heavily implies that Mandy very well might have just ''[[EyeScream clawed his eyes out]]''.
50	* "Little Rock of Horrors" with the singing Audrey II-like space rock that required Billy to get it human brains.
51	** Quickly doused with some NightmareRetardant, courtesy of Music/{{Voltaire}} providing its voice.
52	--> ''Brains, brains, it's okay! It's not a matter if it isn't gray.''
53	** But quickly made scarier through the fact it doesn't use any sort of alien magic or anything, all it promises is to be Billy's best friend. And there is no little boy or girl who doesn't want a friend out there. If Billy hadn't found it, would it have just preyed on some other insecure kid?
54	** There’s also the fact that it has no qualms about who’s its prey. Whether an old man or even a baby, making clear it especially finds those delectable, it’s not a matter if it isn’t gray indeed.
55	*** Speaking of the baby line, the one the alien eats from has an unusually weird and creepy look on it’s face, which doesn’t change even as their brain is taken.
56	** After it eats Mandy's brain, she takes over it after her brain proved to be [[TooSpicyForYogSothoth "too spicy" to eat]]...and now she wants some brains. Even worse, it's implied the brainless zombies (even her previous body) are now under ''her'' control.
57	* "Dream a Little Dream" is an AffectionateParody of ''WesternAnimation/{{Fantasia}}'' and has the darker tone to go with it.
58	** In Billy's dream, Billy initially is overjoyed to be in a seemingly tranquil, beautiful and lovable place that is SickeninglySweet. Then he finds the cute little baby rabbits that transform into huge, nightmarish monsters that chase him. He tries to save the last baby rabbit, but then it too transforms into a monster in his own hands. He then tries to escape the rabbit hole, and almost gets dragged back down by the monsters below. When he gets out, the rabbit hole transforms into a huge mountain that the now gigantic monsters erupt out of to continue chasing him. However, Billy ends up running right into a horde of killer rabbits with sharp claws and huge wicked grins, who don't even move but just vacantly grin at him. And this is where we stop, but Billy's reaction the next morning makes clear the killer rabbits did a number on him.
59	** Grim, meanwhile, dreams of the unfortunate reality he's stuck in - he's Mandy's eternal slave, and at the end is beaten up by an army of Mandy clones. Even when he beheads some of them, they just keep coming and doubling their ranks.
60	-->'''Mandy''': '''Give up. Give in.'''
61	** Finally, the last segment is a parody of the [[NightmareFuel/{{Disney}} one and only]] ''Music/NightOnBaldMountain'' segment. It starts with an imp mischievously dragging Mandy into the couch and causing her to fall down into a volcano (take note that Mandy actually does look unnerved for once). Then the familiar strings of ''Bald Mountain'', or at least approximations of them, cue up as something brews in the lava after Mandy falls in. We then see hordes of nightmarish demonic creatures gathering at the volcano's base in anticipation. Then Mandy finally erupts from the volcano as a fiery demon with a fist raised, as the hellish hordes celebrate in rapturous joy. Mandy then kills the imp that delivered her to the volcano and fully takes control of the proceedings as the lord of evil, or really Satan herself given what the sequence is parodying. The kicker is that she wakes up feeling refreshed and rejuvenated and wanting ''more'' of the pizza that caused her dream.
62	----

65	[[folder:Season 1]]
66	* In one episode, Grim falls for a goth girl and struggles to tell her that he is, in fact, the Grim Reaper. So how does he show her? By ''disturbingly rising from the ground'' while fire forms around him whilst he randomly takes on this slinky look akin to [[Franchise/TheSlenderManMythos Slender Man]] with a horrifying frown throughout.
67	* The ending of "The Really Odd Couple." The idea of being gagged and imprisoned inside a brick wall is terrifying enough for many people, but then there's Mandy's line just before the credits.
68	-->'''Mandy:''' "I'm glad you see it my way."
69	* In "The Halls of Time", Billy and Irwin start to mess around with a few hourglasses that control the lifetime of all people in the show, and when Billy accidentally lets one fall several stories to shatter, it ends up [[RetGone unmaking]] Maxwell Atoms, the creator of the show.
70	-->'''Billy:''' Meh. Probably no one special.
71	** Not only that, but Irwin kills his own brother by throwing his hourglass away.
72	** We get to see Billy's father choking to death, but it's immediately revived by Billy putting his father's hourglass upside down.
73	** At the end, the two end up accidentally putting their own hourglasses, and the ones from Grim and Mandy, upside down, making them grow up backwards until all of them become fetuses, and disappear with a pop, leaving their empty incubators in Grim's hand. The worst part is that Grim is happy watching Mandy wasting away before his eyes. But at the very end of the episode, Grim is unable to put his own hourglass upside down, then gives up, waves at the camera and vanishes.
74	* Most of "Who Killed Who?" is absolutely terrifying, especially if you [[ItMakesSenseInContext haven't seen all of it]]. It's one of the episodes that use {{Scare Chord}}s more often than the normally cartoonish sound effects, adding to the horror even more. That's not even counting the TwistEnding, where it's revealed that Mrs. Doolin really ''was'' a ghost.
75	--> '''Mandy:''' Mrs. Doolin beat Grim. She beat ''death''.
76	** Also, there's a possibility this episode is where Bleedman took inspiration for ''Webcomic/GrimTalesFromDownBelow''. Mandy did the same thing Mrs. Doolin did, only rather than just defeat Grim, she married him, thus taking the power of Death for herself.
77	** Grim's little ghost story about Little Frankie, the boy Mrs. Doolin murdered and made into a scarecrow, is also pretty creepy, although this is offset by the twist that Grim was making up stories about her.
78	* In "Tween Wolf", shortly after Irwin gets mauled by a werewolf with a GoryDiscretionShot, he comes across Billy - and stares at the camera with a low growl, a DeathGlare complimented by an actual dark-brown coloration to his eyes that never shows anywhere else in the series, and ''part of his ear torn off.'' And during his transformation into a wolf you can briefly see his bones jutting out of his body as he shifts in agony.
79	* Nergal Jr.'s introduction episode in "Son of Nergal" involves him pretty much taking over the forms of an entire camp of kids and the man in charge and then hiding their bodies in snowmen. With all of the grace of a SerialKiller, including Billy uncovering their frozen bodies akin to discovering corpses. Nergal Jr. assures that they're just sleeping - but they're never recovered, and Billy ends up joining them with only StatusQuoIsGod saving everyone's hides.

82	[[folder:Season 2]]
83	* Jeff the Spider snapping towards the end of "Spider's Little Daddy". For the entire episode he is [[FriendlyNeighborhoodSpider a very nice spider craving Billy's love]], but Billy is too afraid to see that. Once he hears Grim's rant over being Mandy's servant shortly after Mandy abandons her efforts to train him to be less nice, he pulls a whole 180 as he finally releases his frustrations and actually gets terrifying:
84	--> '''Jeff:''' Love me, Dad! Love me! Love me now!
85	* "Tricycle of Terror", where Billy gets an evil tricycle that brutally attacks anyone that wrongs Billy in [[DisproportionateRetribution any insignificant way.]] He gets the bike in a strange magic portable bathroom that takes him to a creepy ambient version of Pittsburgh, where a creepy British child tells him that he must love the bike forever, or else. The worst part is that the bike is practically [[NighInvulnerability invulnerable]], as it simply rebuilds itself when destroyed. Luckily, Mandy is able to finally finish it off by [[ThereIsNoKillLikeOverKill smashing it with the garage door repeatedly until it stops rebuilding itself.]]
86	** The beginning of the episode where Billy crashes his bike and scrapes his face against the street, '''leaving his exposed skull and flapped skin hanging off of his face'''. No wonder the kids who saw as much screamed in pure terror.
87	* "Nursery Crimes" featured a tale from Mandy that had Billy cast as Humpty Dumpty... who falls to his death and shatters, and his remains are eaten by all the king's horses, men, and villagers for days. It's quite terrifying to think Mandy has that much hate for a person in her heart.
88	** Then we get the already somewhat creepy Pinocchio trying to eat Billy's flesh. Mandy saves the day by carving Pinocchio into a chair, and Pinocchio is seemingly killed when the witch from Hansel and Gretel crushes him under her weight. He gets better in a later episode.
89	** Pinocchio's creepy house, which is silent, aside from a ticking clock, and full of inanimate dolls.
90	** And finally, the ending. Mandy is trapped inside the fairy tale book with Billy, with Grim having fallen asleep on them. Mandy only quietly swears vengeance on us all.
91	--->"Someday, you will all ''pay...''"
92	* The infamous contact lenses scene in ''My Peeps''. The one-eyed optometrist tries to put a contact in, but ends up hurting himself in the process. It caused a lot of people to swear off wearing contact lenses due to the GrossUpCloseUp EyeScream.
93	* The episode where Nergal Junior takes over the teacher, and [[MoreTeethThanTheOsmondFamily gives the class bully a fanged grin that slowly grows]] ''wider than her face''? BringMyBrownPants.
94	*** ''It's on the title card, too!''
95	** Jr. forcing Sperge to become his ''pet'' after he takes revenge on him for his bullying, complete with keeping him in a cage in the underworld, with a terrified Sperge slinking out of his dog house like a beaten, frightened animal. This is thankfully lessened somewhat by Sperge loving the food he's given as it's much better than what he gets at home.
96	* "Circus of Fear" has Gladys' threat to Grim to bring Billy home to her, complete with an extreme close-up of her NightmareFace and frightening graphics, which actually make Grim [[ScreamsLikeALittleGirl shriek]] [[HorrifyingTheHorror with fear]].
97	-->"Listen, mister! ''If Billy isn't back by dinner, there will be'' '''''grim consequences!'''''
98	* The Clucking Doom stage of the video game is based on the episode "Which Came First?," which features Billy and Mandy's school bus breaking down in the desert, at which point the two come across a secret government lab dedicated to growing genetically mutated chickens for the US Army, with eggs containing Acid Yolk and for whom ingesting the meat of the chicken itself causes you to lay an egg containing a mutant chick. Aside from that, the episode featured Pud'n fearing that being stranded in the desert would lead to the kids [[NoPartyLikeADonnerParty having to cannibalize each other to survive]]. By the time the nearby volcano erupts, raining cooked mutant chicken over the camp, Sperg has [[ImAHumanitarian already eaten Pud'n's arms and legs]].
99	-->'''[=Pud'n'=]''': Giant chickens from the sky! Now we won't ''have'' to eat each other to survive!\
100	'''Sperg''': (Though a mouthful of Pud'n's limbs) [[BlackComedyCannibalism Tough luck for you, kid.]]
101	[[/folder]]
102
103	[[folder:Season 3]]
104	* In "Sickly Sweet", just to scare off a couple and real estate agent, Grim transforms a tiny, innocent flower into a giant, plant-monster... ''thing'' that begins to trash the ever-living ''hell'' out of Billy. It's made much worse as Billy screams "IT'S DIGESTING MY '''''NOOOOSSSEEE!!!!!'''''". The real estate agent responds with some mood-clashing CasualDangerDialogue:
105	--> '''Real Estate Agent''': Looks like we've got a bit of a ''weed'' problem.
106	** Mandy's SanitySlippage throughout the episode until she finally snaps at the end.
107	*** '''[[RageBreakingPoint "I'll KILL YOU!"]]''' ([[NightmareRetardant If "Haw-HEE! Haw-HEE!" doesn't lighten the mood afterward]])
108	*** Mandy eventually abandons any attempt at losing the mask, preferring to go full BodyHorror and turning into a hideous donkey monster rather than act ''nice''. Granted, it didn't help that Billy and Grim took shameless advantage of her and tried to basically enslave her as a form of revenge against her abuse.
109	----> '''Grim''': Well, we knew this was going to happen from the start.\
110	''WHAM''\
111	'''Billy''': Yeah, but it was [[WorthIt worth it]].\
112	''WHAM''\
113	'''Grim''': I just hope we don't need to sit down for the next couple of weeks.\
114	(''cut to show Grim and Billy tied up and repeatedly kicked from behind by Mandy in monster donkey form'')\
115	'''Mandy''': [[HonorBeforeReason Well, a girl's gotta have her principles]]. (''brays, then [[CameraAbuse kicks the camera]]'')
116	** The episode ''starts with Billy's SEVERED ARMS (complete with bones sticking out of the end) BEATING HIM SENSELESS.'' ([[ItMakesSenseInContext He put on a pair of magic gauntlets that made them pop out and come to life]])
117	* The episode, "Attack of the Clowns". Expect to find some {{Monster Clown}}s in this one.
118	** Mandy's intro quote before the episode:
119	--->Mandy: No matter how bad it seems, [[TemptingFate it could get worse]].
120	*** What happens immediately after that quote? [[JumpScare She turns into an ugly green reptile-like creature and screams at the screen (or she at least has her mouth open while there's a thunder sound effect)]]. This all happens in a flash...
121	** That creepy goddamn clownhead that Grim tries to bring to life to help Billy to get over his fear of clowns. It seems the magic didn't work at first, so they leave it in the basement, only for it to suddenly come to life, ''sprout fangs and a balloon body'', and drag itself along the floor, where it meets the cast once they return to the house, and ''promptly devours all of them'' then runs off.
122	** Billy's psychotic breakdown after having a talk with his "inner fratboy" who tells him to get angry at the things he's afraid of.
123	* In "Chocolate Sailor", Billy turns completely into solid chocolate after eating too many supernatural chocolates. If that isn't enough, Billy even begins to ''eat himself'', saying to Mandy that "...it's not that painful" at one point, and continues to do so, reducing himself to a limbless torso. The rest of his body is then lost to ''seagulls'' who have developed a taste for chocolate due to hanging around the Chocolate Sailors ship, reducing Billy to a mutilated head. At the episode's climax, the Chocolate Sailor gives Billy the antidote, but with a twist: it's in a box of assorted chocolates and Billy has to pick the right one. Since Billy is [[IdiotBall stupid incarnate]] (the antidote bar is called ''Antidote''), he eats the whole assortment and promptly [[MadeOfExplodium explodes]]. The episode ends with Mandy and Grim eating hot fudge sundaes, with them saying Billy is in a better place. The bottle of hot fudge syrup they have has an illustration of Billy on it who says "''I like chocolate!''"; implying that they scooped up all that was left of Billy and dumped him into chocolate syrup containers ([[LetsMeetTheMeat and to add that Grim and Mandy are eating hot fudge sundaes with sauce made of him...]])
124	* The ending to "Hog Wild". Even worse is that it [[GainaxEnding comes out of nowhere]]. Specifically: the closing iris closes on Billy's head, suffocating him as his eyes pop out.
125	* "Wishbones".
126	** [[https://www.youtube.com/watch?v=wmZAzVS8Nw4 Pud'n's part]]. (shudder) What really drove that one home is how realistic the bunny was drawn. When Pud'n's holding the cute bunny and it lets out a terrifying shriek as its face contorts (pictured above). Cut to Pud'n's face looking like he pooped himself. And when the bunny rises out of the fire of the destroyed truck in an obvious ''Franchise/{{Terminator}}'' [[ShoutOut homage]], complete with its insides showing and says "Of course I forgive you, Pud'n! I forgive you because I love you... And I love you, to ''death''." The epic MoodWhiplash (the truck had just blown up from [[MadeOfExplodium having its cargo, a]] ''[[MadeOfExplodium giant pillow]]''[[MadeOfExplodium , hit with the]] ''[[MadeOfExplodium creme filling from an eclair]]'') really made the moment scary. It does just turn into standard cartoon violence for parts of it, but the fact that it goes from that to the said quote is horrifying. That voice is just awful.
127	** It was disturbing that Pud'n was searching through the garbage for candy.
128	** The part where he [[EyeScream rips the cactus out of his eye]] revealing a hideous, skinless red eye.
129	** Skarr's wish is nothing to sneeze at either. The statue he stands on grows out of Earth's atmosphere, causing him to suffocate in space. His face turns blue, his eyes bug out and we hear him choking before he explodes.
130	* "Bully Boogie" ends with Grim and the Boogie Man deciding to figure out who's scariest by picking someone and random and trying to scare the daylights out of them. Boogie turns into a frightening-looking (but relatively tame) werewolf to do so, and is confused when all Grim plans to use is a rubber ducky with demon horns. One scene transition later, Boogie pops up in a bathtub and "roars" at the kid in it, who is completely unfazed by him and, in fact, is ecstatic that a new pet just spontaneously appeared in front of him. Grim's rubber duck pops up out of the water next, and the kid plays with it for a moment, squeezing the duck and it makes cute little quacking sounds. And then the quacks suddenly sound deeper. The duck starts getting bigger, then changes from a basic rubber bath toy into an outright monster with jagged teeth as it grows to the size of a dinosaur and ''really'' roars. The scares for the audience are deflated a moment later when its head pops and Grim comes out to say "Boo!", successfully terrifying the kid with all that build-up, but ''holy shit!''
131	[[/folder]]
132
133	[[folder:Season 4]]
134	* In "My Fair Mandy", she smiles at the end of her ''Over the Rainbow'' song cover...and reality falls apart. [[NightmareRetardant Turns out now]] the main trio and Irwin are in [[WesternAnimation/ThePowerpuffGirls Townsville]].
135	* Then there's the episode with the zipper, where Billy uses the zipper to remove his left arm and replace it with the cat's head.
136	* The Cthulhu episode. The ''real'' Cthulhu (the one playing golf is really one of his Star Spawn) shows up and eats Billy at the end, meaning they failed to stop him.
137	** And when Billy's nose changes into a squid-like appendage which can flip up and spawn hundreds of insect-like creatures with Billy's head, sharp teeth and tiny tentacles. Screaming wildly, they all fly to Grim and attack him.
138	* The so-called ChristmasEpisode. BadSanta? More like blood thirsty Santa. This must be the first time a show's Christmas special is scarier than its HalloweenEpisode, which is quite mild.
139	[[/folder]]
140
141	[[folder:Season 5]]
142	* In "Keeper of the Reaper", Irwin is brought into Underworld Court while in the bathtub. When he puts on his glasses, he sees the monsters inhabiting the room [[GrossUpCloseUp in disgusting detail]].
143	* The ending to "Scary Poppins", which shows Mandy apparently controlling the minds of ''everyone in Endsville'' (except for Grim).
144	-->'''Mandy:''' This is ''my'' world. I'm just letting you live here.
145	* "Spider-Mandy" had Mandy slowly transform into a Giant Spider, much to Billy's arachnophobic horror. For Billy's "son" Jeff, though, it's love at first sight.
146	** The ending too, where everybody in town has become a mutant spider creature. This proves to be in-universe nightmare fuel to Billy.
147	-->'''Spider!Gladys:''' Do you want breakfast...BEFORE I EAT YOUR HEAD!?
148	[[/folder]]
149
150	[[folder:Season 6]]
151	* The character of Pinface considering his voice is done by John Kassir (you know him as the voice of the Crypt Keeper in ''Series/TalesFromTheCrypt''.
152	[[/folder]]
153
154	[[folder:Movies]]
155	* The origin/adaptation of Jack-o-Lantern in ''Billy and Mandy's Jacked Up Halloween''. He was once a village fool who loved playing pranks. The problem with Jack was that he didn't know when to stop and would pull dangerous pranks on Endsville, sometimes pranking the same person more than once. When the townspeople couldn't take it anymore, they pulled a prank of their own. They sent a "snake in a candy jar" prank to the Queen and signed it from Jack. When she opened it, the rest was history. After being executed, Grim was sent to take Jack, but Jack tickled him and stole his scythe. He wanted to make a deal: if Grim gives him immortality, he will give him back the scythe. Grim did so, but as payback for being tricked (which he doesn't like), he decided that Jack [[OffWithHisHead would not be showing his face around town again...]] '''''[[OffWithHisHead ever]]'''''. After that, Jack replaced his head with a pumpkin and his pranks became more cruel than ever as payback for what Endsville did to him.
156	* ''Billy and Mandy's Big Boogey Adventure'' [[NightmareFuel/BillyAndMandysBigBoogeyAdventure has its own page]].
157	* The trailer to "Wrath of The Spider Queen". The Spider Queen's singing as Grim says the title of the special (with him also giving a good punch to the fourth wall in the actual special) is particularly unnerving.
158	[[/folder]]
159
160	[[folder:The Video Game]]
161	* The whole concept of magic balls of energy that can send someone into a violent fit of rage just by being in their presence.
162	* The Clucking Doom stage. The three phases to the level are as follows:
163	** The laboratory, which has chickens, stripped of all their feathers, floating helplessly in capsules filled with strange liquid. Said capsules can be destroyed, causing the chickens to collapse to the floor, presumably dead.
164	** The second segment is the interior of a volcano, and it's probably the tamest of the three segments.
165	** The third segment, however, has you fighting on a school bus being chased by [[Attackofthe50FootWhatever a giant chicken]]. If you fall off the school bus, you roll down the road, straight towards the giant bird. And the chicken also goes out of its way to pick off the other vehicles on the road... The icing on the cake, however, is the incredibly disturbing music they chose to have play before each and every battle on this stage.
166	* The first time you use Boogie's Supermove it's likely you'll get a scare: Boogie yells that "With Horror's Hand, I'll be invincible!" and then yells "Boo!" at the opponents... nothing happens for a bit and then...
