History NightmareFuel / TheGrimAdventuresOfBillyAndMandy

* "Dream a Little Dream" had scenes based on [[NightmareFuel/{{Disney}} the "Night on Bald Mountain" sequence from]] ''WesternAnimation/{{Fantasia}}'' but not as scary. It also had much more horrifying segments for Billy and Grim's nightmares. 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 nightmarish monsters that chase him. However, Billy ends up running right into a horde of killer rabbits. 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.

* The infamous contact lenses scene in ''My Peeps''. The one-eyed optometrist tries to put a contact in, but ends up hurting himself. It caused a lot of people to swear off wearing contact lenses.

* Jeff the Spider snapping towards the end of "Spider's Little Daddy." "Love me, Dad! Love me! Love me now!"

* ''Irwin gets a clue'': Hoss' backstory, where he was constantly one-upped by a guy called Kyle, whom he now keeps chained to a radiator in his basement, would be this if Kyle wasn't a traffic cone.

* 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]].

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]].

* In "Tween Wolf", shortly after Erwin 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.

** 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'''.

** 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

** The third segment, however, has you fighting on a school bus being chased by 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.

* 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 oponents... nothing happens for a bit and then... [[https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRcFXX15ZSWEDBcmJ_5aBhaRPO-LCL5sn-X4o0tgtpIvaLcxcxg Horror's Hand appears briefly]] [[JumpScare with a sudden yell]] which causes the oponents to explode.

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

** 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]]!

* "Dream a Little Dream" had scenes based on [[NightmareFuel/{{Disney}} the "Night on Bald Mountain" sequence from]] ''WesternAnimation/{{Fantasia}}'' but not as scary.

* ''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.

-->"Some day, you will all ''pay...''"

* The Clucking Doom stage of the videogame is based off of 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]].
-->'''[=Pud'n'=]''': Giant chickens from the sky! Now we won't ''have'' to eat each other to survive!
-->'''Sperg''': (Though a mouthful of Pud'n's limbs) [[BlackComedyCannibalism Tough luck for you, kid.]]

** [[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. 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.

* The ending to "Hog Wild". Even worse is that it [[GainaxEnding comes out of nowhere]]. Specifically: the closing iris closes on Billy's head and a bunch of blood and snot sprays from his nose and his eye pops out.
