Nightmare Fuel: Tiny Toon Adventures
- Plucky channeling Einstein in "Never Too Late to Loon" is a direct shout out to the Pink Elephants on Parade scene from Dumbo. It's equally mindscarring.
- Wackyland and its surreal humor. They try to have Babs decapitated for having self control.
- The earthquake in "Journey to the Center of Acme Acres," as well as the Gremlins.
- As well as Plucky going crazy with greed to such an extent, he openly disregards being in danger from the Gremlins.
- One segment of the Halloween episode "Toons from the Crypt" had Elmyra, an animal lover whose affection was always disastrous for the target animal, mourning her late pets... whereupon they rose from the dead Zombie Apocalypse-style and came after her. Their being zombified didn't prevent her from lavishing her destructive affections on them, however. One truly scarring moment shows her plunking a zombie dog and cat into a tub of soapy water to give them a bath. But then she pulls out her hands and they're covered in muck. In other words, the zombie pets fell apart in the water.
- In the end it turns out it was just a nightmare though Elmyra admits it was fun seeing her old pets again, so what does she do? She goes to the cemetery to dig them up! Elmyra wanted to play with her pets' dead bodies, zombies or not! It was so scary it even scared the crypt keeper/Buster!
- The first segment of the episode, titled "Wait 'Till Your Father Gets Even", is pretty scary too, especially the ending, where Plucky is tied to a board being cut in half by a saw as punishment for gambling.
- In "Fit to Be Stewed," a witch named Sandy tried to cook Buster and Babs in a stew—until she realized Babs was a cartoon rabbit and her recipe called for a real rabbit. So she used her magic to turn Babs into a helpless real rabbit, unable to save herself.
- A variation on the usual Michigan J. Frog shorts. In this one, the frog was dead and awaiting dissection in a biology class, but came back to life when the teacher's back was turned. It was immeasurably creepy – especially the ending, where Hamton tried to bury it in a pet cemetery, but all the other animals came back to life... and sing.
- Wolvertooth from the Pluck Twacy short, which basically consisted of a closeup of Bugs Bunny grinning with a bunch of sharp pointed teeth.
- "Slaughterhouse Jive" as a whole can get pretty freaky. This is one of those things that can scare most meat-loving children into becoming vegetarians and at the same time scare kids away from vegetables.
- "Sawdust and Toonsil" is easily one of the darkest episodes Tiny Toons has ever produced. The story starts with Silas Wonder's circus coming into town, and the man himself invites Buster, Babs, and Plucky in to see his "wonderful wonderpieces". Then everything goes downhill. By the end of the episode, Silas Wonder is revealed to horribly, HORRIBLY mistreat the animals he has in his circus (and it's practically said that he poached them) and gets Killed Off for Real, the ONLY Tiny Toons villain to actually die.
- "One Beer" was a parody of the Very Special Episode that demonizes alcohol and ends with everyone dying (even though Buster, Plucky, and Hamton reveal that the whole thing was just part of the show, it did get complaints for cheapening the Aesop that "Underage drinking isn't cool and will lead to a life of ruin" and was banned until the 2000s and 2010s, when it was found on the DVD release of the show and in reruns on The Hub).
- In "The Undersea World of Fifi," Elmyra is desperate to catch sea monkeys. She ends up finding a plug at the bottom of the ocean, which pulls everything, even the universe, into it. "But at least I got my monkey-wonkey!"
- The same goes for the ending to the episode with Duck Dodgers in it, and that ending makes it even worse.
- Mr. Hitcher from How I Spent My Summer Vacation qualifies as he's a parody of Jason Voorhees and John Ryder. The whole extended sequence where he chases Buster and Babs even has him swinging his chainsaw wildly about, which causes part of the mine to collapse. And he does it with a really deranged look on his face.
- And then it turns out, Hamton has brought Mr. Hitcher to Acme Loo, thinking he's a friend. Plucky gets chased around the classroom by Mr. Hitcher while the students and teachers don't even notice!
- The episode "Hare Raising Night" features Dr. Gene Splicer, who in his very first scene is described as a certified loony who performs deranged animal mutation experiments. Cut to three guinea pigs, who, when Splicer opens the cage, are seen cowering in fear as he takes one guinea pig away (to be presumably experimented upon) as the camera cuts to static. It only gets worse when Buster and group arrive to stop him (actually just Buster; he tricked Babs, Plucky, and Hamton into coming), as he takes Plucky away for his brain, is extremely abusive to his creation Melvin, and at the end tries to mutate the four of them, and then ends up falling into his own vat of mutation goo. However, his Crowning Moment Of Nightmare comes in what he says after trapping the four in his Animal Experiments Lab and talking to them via a creepy-as-hell distorted static-y image of his face (which is then zoomed in upon for good measure):
Dr. Splicer: Aah, guess again kiddies. I got a little riddle for ya: what do you get when you cross two bunnies, a duck, and a pig?Buster: I don't know.Dr. Splicer: Neither do I, but we're gonna find out!
- The segment "Duck In The Dark" from "Best O' Plucky Duck Day", in which Plucky keeps having nightmares after watching a marathon of horror movies, the scariest bits are at the beginning in the movie Plucky watches as a fawn is stalked and presumably killed offscreen by Eddie Couger (A Freddy Krueger parody), and later when Plucky tries to escape from Eddie and tries to wake up Buster only to discover that he's turned into a horrifying monster with an eyeball hanging out of one his sockets. And at the very end after the nightmares are over there's the angry Nightmare Face Buster makes after learning Plucky learned absolutely nothing from them and has gone back to happily watching the horror films.
- The entire "Boo Ha Ha" segment from "Return of the Acme Acres Zone" where a ghost terrorizes Plucky and Hamton. The different Eldritch Abomination forms he takes throughout the short are horrifying. And then there's the ending, where he takes them to hell with them. The End!
- The effing Banshee in the second "Viewer Mail Day" segment.
- The "find the object" game Buster and the Beanstalk isn't too frightening for the most part, but as the manual warns you, Elmyra is hunting down Buster and Plucky as they search for key segments. Once she's closing in, she'll taunt you from parts unknown; you'd better find what Babs tasked you with retrieving before Elmyra materializes out of nowhere to capture the boys and lock them up in an endless kennel.
- Tad the Imaginary Friend's demise in "A Pigment of His Imagination". When Hamilton finally stands up to the JerkAss, he shrinks down to toy size and his voice becomes squeaky. Fitting, given how he was a big, muscular dude...but it was a bit much for Sweetie Pie to promptly EAT HIM, complete with Ted screaming in horror right before getting chomped, and Sweetie's pudgy belly and satisfied grin afterwards. And everyone just goes right back to partying like nothing happened.
- And then there's the loud *crunch* when Sweetie eats him, not to mention her crazed look just before that. If she'll eat Tad for seemingly no reason other than him being small enough, what would she do if she saw ANYONE ELSE suddenly downsize?
- She also tried to eat a shrunken Dizzy in "Squish". It was just a dream sequence, but still pretty damn creepy. Dizzy's terrified whimper and her "it'll only hurt a little!" line didn't help either.
- On the former Troper Tales page, one troper explained that he or she had a fear of toilets as a kid due to some bad timing during a TTA rerun on Nickelodeon:
It all started with an episode of Tiny Toon Adventures I was watching on Nickelodeon one afternoon (The one that had the short involving Baby Plucky getting potty trained), when there was a scene of the toilet overflowing; starting to flood the bathroom. On the first commercial break after that short, was none other than the anti-drug PSA with a girl trapped in a room flooded almost to the ceiling; as she struggled to reach the surface and eventually drowned. It gave me nightmares for days; giving me a fear of toilets in the process (I still used them, but I'd run like hell after flushing it; fearing that if I stayed any longer, than the door would slam shut on me as the toilet overflowed to the point of flooding the bathroom to the ceiling). I got over it, though I would have never had those nightmares in the first place had it not been for the poor timing of an already disturbing PSA.
