History NightmareFuel / LooneyTunes

* While the 1953 cartoon "Lumber Jack-Rabbit" is entirely comedic and light-hearted like most shorts, the same cannot be said for the [[https://www.youtube.com/watch?v=4tf939p_Hlo slightly-tweaked "Warner Bros. Pictures, Inc. present" logo at the start]], where the shield zooms farther than usual and ''almost engulfs the entire screen!'' Worse, the twanging noise is tweaked as well to sound more horrifying! The cartoon was originally screened in 3D... would that make this effect better or worse?

** Any and all "exotic"-sounding music in "WesternAnimation/WarAndPieces" (such as for the "Secrets of a Harem" peep show (actually a disguised shotgun) and in China where Wile E. Coyote mistakenly winds up and meets a Chinese Road Runner).

* The ending of ''Dr. Devil and Mr. Hare'' was the most disturbing for any WesternAnimation/BugsBunny cartoon as his FrankensteinsMonster-like robot he created to beat up Taz then turns on him as Bugs wails with genuine terror, "No, no, no, not me, Frankie! Not me, Frankie! No, Frankie, No! No!" After getting [[BattleDiscretionShot a savage off-screen beating]], Bugs hobbles back on camera to ask [[IsThereADoctorInTheHouse if there's a doctor in the house]], which normally would've added some levity, but thanks to Bill Lava's horror movie-esque music, it only makes it ''worse''. Compare to the ending in "Half-Fare Hare", which also ends with Bugs taking a beating (he accidentally hits his head and gets a series of [[CranialEruption head bumps]]), but thanks to the goofy music it's funny rather than off-putting.

* A third Dr. Jekyll influenced episode, ''Hyde and Go Tweet'' has Dr. Jekyll drinking the potion and then turning into Mr. Hyde, and Tweety (who is in the room with Sylvester) ends up getting exposed to the potion as well, (he hid in the bottle) turning him into this gigantic, frightening, and grotesque figure, which scares the daylights out of Sylvester. It all turns out to be a DreamWithinADream, though, but Sylvester thinks it might actually happen at the end and comedically goes berserkers, in which two cats and Tweety himself consider acting strange.
* Some of Bill Lava's music from the 1962-1964 period ventures into this, since he produced a far more "modern" (meaning "dissonant") sound than Carl Stalling or Milt Franklyn. As a result of this, some of his scores during this era create an ominous sense of dread. Some examples: The aforementioned "Bugs gets beat up by the robot" scene in "Dr. Devil and Mr. Hare"; some moments in "Martian Through Georgia" when the Martian is on Earth (and especially as he finds himself in a hellish landscape), as well as ending on a LastNoteNightmare in the form of a trilling flute-like sound; what little music there is in "WesternAnimation/NowHearThis"; the shrill sting after Sylvester is blown up by his own rocket in "The Jet Cage"; the moment when Sylvester screams during the flashbacks in "Freudy Cat", as well as the music in said flashbacks, consisting of past Sylvester cartoons, unnaturally mixing Lava's music with Stalling's, coupled with a stock piece by Philip Green; the title card to "Mad as a Mars Hare" (which could've easily been used for a '50s horror movie without missing a beat); Yosemite Sam in Hell in "Devil's Feud Cake" (more on that later); the catapult montage in "To Beep or Not to Beep" (which almost sounds like a death march); the establishing shot of WWI-era Germany in "Dumb Patrol"; and any and all "exotic"-sounding music in "War and Pieces" (such as for the "Secrets of a Harem" peep show (actually a disguised shotgun) and in China where Wile E. Coyote mistakenly winds up and meets a Chinese Road Runner).

** A big offender is ''The Solid Tin Coyote'', involving Wile E. constructing [[AttackOfThe50FootWhatever a gigantic]] [[HumongousMecha mechanical coyote]]. Even the PerpetualSmiler Road Runner is actually scared!

* Another similar cartoon, ''Dr. Jerkyl's Hide'', has Sylvester drinking up the formula himself, believing it to be soda pop, and turning into a really terrifying-looking monster cat who [[NoHoldsBarredBeatdown senselessly beats]] Alfie (otherwise known as Spike). The second time when he transforms, he chuckles evilly at Alfie's horrified expression before using his fingers to make Alfie's face form a smile, unsheathes his claws, and starts marking Alfie's jaw with dotted lines before the scene cuts to Chester outside of the door hearing what he thinks to be Alfie beating up Sylvester, until Alfie walks out in cross-sections. When asked by Chester if Sylvester hurt him, Alfie answers, "Nah, he just scratched me" before falling apart. Though it also doubles as a MomentOfAwesome for Sylvester since he gets to inflict some sweet payback on Alfie for his treatment of him.

* The WesternAnimation/WileECoyoteAndTheRoadRunner cartoons directed by Rudy Larriva in 1965-66 often veer into this territory, with their DerangedAnimation, ominous background music cues by the aforementioned Bill Lava, some freakish OffModel expressions, at times some unusual sound effects, and usage of the fairly creepy "Abstract WB" [[VanityPlate logo sequences]] (which were ironically originally designed by Chuck Jones for "Now Hear This"). That is, if you can get past the fact that they were mostly a cheap imitation of Chuck Jones's Road Runner cartoons.

* ''WesternAnimation/TheCaseOfTheStutteringPig'', with its gloating, nasty, audience-abusing villain Lawyer Goodwill, whose hideous looks are only matched by his gruesome plans for the pig inheritors. See the picture above.

** The beginning of this cartoon seems like a Shout-Out to the Night on Bald Mountain sequence from Fantasia.

* "Porky's Bear Facts" is a ''Looney Tunes'' version of ''The Ant and The Grasshopper''. Porky and his dog work all Autumn to get some food in the house but his neighbor the bear is lazy and doesn't work at all. When Winter comes Porky has plenty of food but his neighbor has none. When the bear and his dog try to eat the last bean a mouse ate it causing the bear to burst into tears. The bear's dog tells the viewers that he wouldn't be surprised if his owner would try to eat him then sees the bear looking at him with an evil scary look with a knife and fork in his paws, advancing towards as the dog backs away in fear and pleads for him not to eat him! Luckily they pass by Porky's house and Porky's willing to share his food.

** One drone sets fire to a trash can... And it's promptly revealed that the trash can is SENTIENT and it runs around screaming.

-->"Awise, stowm! Norf winds, blow! Souf winds, blow! Typhoons, hurricanes, earthquakes! SMMMMOOOOOOOOOGGGGGG!!!!"

* Sylvester's insomnia and ensuing nervous breakdown in ''WesternAnimation/BirdsAnonymous'' demonstrates a little too well the toll that withdrawal from an addiction can have on an addict's psyche and can border on psychological horror. Just look at the TropeImage used for this cartoon on this site!

** Paul Bunyan's dog Smidgen, nearly [[SwallowedWhole swallows Bugs Bunny alive]], and it appears Bugs has finally met his match as Smidgen is gigantic and there's [[GiantEqualsInvincible nothing he can do to fight back]]. As Smidgen picks his teeth however, Bugs comes out unharmed on the top of the toothpick.

* The cartoon "WesternAnimation/{{Pigs Is Pigs|1937}}", where a gluttonous piglet is force-fed by a mad doctor to the point that even he is clear pain, until he explodes. Luckily, it was AllJustADream.

** This was even sighted as the inspiration for a sequence in WesternAnimation/TheRenAndStimpyShow episode [[Recap/RenAndStimpy2x12RoyalCanadianKiltedYaksmen "The Royal Canadian Kilted Yaksmen"]] where one of the yaks goes COMPLETELY INSANE.

** The director's cut ending is arguably worse - instead of the dog shooting himself, Bugs ''shoots him at point-blank range''.

* While "WesternAnimation/HareTonic" is just your typical lighthearted Bugs Bunny cartoon, the ending somewhat manages to be a bit creepy. As Elmer Fudd chases Bugs out of his house with a rifle, Bugs stops him dead in his tracks to show him that the audience has somehow gotten infected by the "Rabbititis" disease, freaking out Elmer to the point that the poor guy retreats into his house. Of course, it's just another trick played by Bugs, but as if him deceiving Elmer wasn't enough, he then tells the audience that if they had "Rabbititis", they'd see red and yellow spots, which promptly show up on the screen around Bugs as the music starts to build up. Bugs then says that the dots would swirl around, which they do, and last but not least, he says that everything would go black. Immediately after Bugs says that, the screen does just that as the music comes to a dramatic finish, and finally, we hear Bugs laughing in the background.

* The 1944 cartoon ''Hare Ribbin''' has two endings, with both being very dark. While the released ending is the standard SuicideAsComedy ending for a '40's Looney Tunes short, the scrapped ending is so dark that it was banned from being released. Instead of the dog shooting himself, Bugs ''shoots him at point-blank range''!

* The self-aware Dr. Moron from ''Water, Water every Hare'' stands out among the rest of Bugs Bunny's adversaries by preferring the direct approach, he simply throws his axe at the hare's head giving him just a split-second to duck in fear and avoid getting butchered.

* Bugs Bunny and the gremlin come close to dying in a plane crash at the end of "[[WesternAnimation/FallingHare". Thankfully, the plane runs out of gas and remains suspended just a few inches away from the ground, but still, a plane crash is fatal for the most part.
