* The WesternAnimation/LooneyTunes short ''"Now Hear This"'' is a NoDialogueEpisode set in a surreal landscape that's apparently a minimalist version of London. It involves a British gentleman getting into all manner of at-times-creepy weirdness upon finding an apparently cursed ear trumpet. Strangely behaved shapes appear inexplicably, accompanied by discordant noises, and at one point the poor bloke is plunged into darkness while being menaced by dozens of mean, staring eyes and floating text reading "PUNK" and "WISE GUY". [[spoiler: After abandoning the device in favor of his old one, we promptly find it was ''Satan's horn''.]]
** Worse if you look at the story as an analogy for an old man's struggle against the onset of senility, or schizophrenia.
* Norman Normal, yeah it's really a great cartoon altough with a lot of MindScrew, but then the ending [[spoiler: [[GainaxEnding the events of the cartoon are revealed to be inside the head of another, larger version of Norman]], visible through a door inside his head. This version then ends the film by closing the door on his head..]]. .

** Rudy Larriva's Road Runner cartoons in general can be ominous and nightmarish at times (if you can get past the fact that they look like a cheap imitation of Chuck Jones' work), and not just the one above. Some good examples include ''"Highway Runnery," "Chaser on the Rocks"'' and ''"Shot and Bothered."''
* ''The Case of the Stuttering Pig''.
* ''Satan's Waitin''', in which Sylvester ''literally goes to hell'' just for doing what cats do, e.g. chasing Tweety Bird.
* ''"The Big Snooze"'' being the most blatant. Lampshaded in three Chuck Jones-directed cartoons: ''"Scaredy Cat," "Claws For Alarm,"'' and ''"Jumpin' Jupiter"'', where Porky takes Sylvester to these scary places to sleep for the night, and only Sylvester can see the scary things ''just'' about to happen to Porky...
* ''"Chow Hound"'': [[spoiler: ''"And this time, we didn't forget the gravy!"'']]
* ''"PorkyInWackyland"'' can be a little ''too'' bizarre for some.
* ''Porky In Egypt'' (1938): [[http://www.youtube.com/watch?v=9NIuGkSikOU In this scene]], Porky's camel Humpty Bumpty starts to hallucinate while in the desert heat.
* ''Invasion of the Bunny Snatchers'', while being one a modern-day favorite, never fails to give viewers the creeps. ''Especially'' the [[UncannyValley doppelgangers]]. ''*Shudder*''...
* A scene from ''"Greedy for Tweety"'', in which Sylvester is given sleeping pills and as he opens his eyes as he goes to sleep, the bulldog is [[LightFlickerTeleportation coming closer and closer]] wielding a baseball bat, and Sylvester not being able to move or react because he's doped up on pills. The final shot has him raising the bat and '''''POW.'''''
* Charlie Dog's breakdown in ''"Often an Orphan"''.
-->[[FunnyAneurysmMoment "Look! It's the towers! THEY'RE FALLING!!! AAAAAAAAHHHH!!!"]]
* The GrotesqueGallery of bad guys in ''"The Great Piggy Bank Robbery"''.
* The cartoon ''"Pigs Is Pigs"'', where a gluttonous pig is force fed until he explodes. Luckily, it was AllJustADream.
* The end of ''"Leghorn Swoggled"'', where Foghorn Leghorn is knocked unconscious (to the sound of a sputtering engine!) and dragged on a toy train into (presumably) Henery Hawk's oven. Made all the more scary when you consider that this is otherwise one of Foggy's less obnoxious cartoons.
* The end of ''"Long Haired Hare"'', where Giovanni crawls out of the remains of the Hollywood Bowl, his tuxedo shredded, his face badly beaten, and his hair a completely different color. Bugs notices one last piece of the Bowl dangling from a support beam, cues the singer to sing that high note one last time, and then the last piece drops. Off camera, we hear a crash, and the singer goes completely silent...
* The obscure Porky Pig short ''"Fish Tales"'' (1936, Jack King) is pretty unsettling when you're a kid. For those who haven't seen it, it involves fisherman Porky getting caught by a family of talking fish and being cooked in an oven.
* Things are often disturbing for no other reason than how bizarre they are. Take the early Egghead cartoon where he hunter says that there are no other hunter's about, whereupon a hunter emerges from behind every bush around him.
* ''The Ducksters''. "You'll be sorry!" So Daffy kills whoever said it with a rifle and proceeds with the episode.
* ''"Draftee Daffy"'' combines AdultFear (Daffy Duck ''really'' [[DraftDodging doesn't want to be conscripted]] and face [[WarIsHell the horrors of war]]) with the genuinely (but possibly [[AccidentalNightmareFuel unintentionally]]) creepy figure of "The Little Man From the Draft Board", a [[NoNameGiven nameless]] government official with odd mannerisms[[note]]Especially when he peeps in Daffy's windows[[/note]] who [[ImplacableMan will go to any lengths to conscript Daffy]].
** At the end of the cartoon, Daffy [[spoiler: ''dies and goes to Hell'']], but is at least happy to have finally and totally [[DraftDodging dodged his draft]]. But then [[spoiler: ''Satan himself'' turns out to actually be The Little Man in disguise.]]
* The LaserGuidedKarma the cat and mouse inflict on the bulldog in the ending of ''Chow Hound''. at least from the point of view of the antagonist. "[[WaferThinMint And this time, we didn't forget the gravy]]."
