History NightmareFuel / Rugrats

* The Passover special, with Angelica as the Pharaoh. If you're familiar with the story of Moses, the tenth plague causes the first-borns to be killed. The fear sets in when Angelica's conversation with her father reveals that since she's an only child, that technically makes her a first-born.
* "Babies In Toyland": There's the ImagineSpot where they're fighting the Mouse King, Angelica threatening Dil that "he'll never have another Christmas again for the rest of his life", the ReasonYouSuckSpeech Santa gives Angelica right before he quits, and the mechanical [[ChristmasElves elves]] in the dimly-lit workshop after Angelica promises to be good.

* The first aired episode "Tommy's First Birthday" has Angelica's shadow when she's placed in the crib and she approaches the babies.
* The episode "Special Delivery" has Tommy exploring the post office, and goes through the chute to the dead letter office, on a conveyor belt leading to what is best described as the junk-mail pit of death, complete with the skeleton of a postal worker who had apparently fallen in years before.[[note]]However, the skeleton could have just been an old Halloween prop.[[/note]]

* In the episode "Reptar on Ice" there was a creepy scene showing the lizard's point of view of how humans look, first Tommy's face up close, then Phil and [[http://dw91iscgvb0p5.cloudfront.net/assets/data/1091_3ef7a830ae1b751483781713ac0367fd.jpg Lil]], it is really horrifying.
* In "Chuckie vs. The Potty", Chuckie [[NightmareSequence has a nightmare]] where his potty-training is like death row, complete with screams of ''"Not the chair! NOT THE CHAIR!"'' Just to make it even creepier, the sequence features ''all'' of the babies--Phil and Lil appear as the prison guards that march Chuckie to the chair, and Tommy is an [[DissonantSerenity eerily calm]] priest who tries to console him. The bit ends with Angelica as the "executioner", who pulls off her mask to reveal one of the creepiest SlasherSmile and EvilLaugh combinations EVER, and [[FunWithFlushing flushes Chuckie down a giant toilet]].

* Then there's the episode where Stu's latest invention is Mr. Friend, an [[NightmareFuelStationAttendant unintentionally creepy-looking]] robotic [[MonsterClown toy clown]]. Given the toy's erratic and disturbing behavior, the babies' [[{{Malaproper}} malapropism]] "Mr. Fiend" may be a more accurate description. It gets worse when Tommy and friends have to fight off a small army of malfunctioning Mr. Friend dolls.

* Another episode was played out like a sci-fi movie with the parents as aliens. It turns out to [[AllJustADream be a dream]]... [[OrWasItADream but then]] it ends with Angelica ''stranded on a desert planet trying to dig for food'', [[MindScrew after Tommy wakes up]].

* Chuckie's {{nightmare sequence}} in Spike's doghouse at the beginning of "In The Dreamtime" where he approached Tommy (who was facing away from the camera) and tapped him on the shoulder, only to have Tommy's [[ExorcistHead head rotate]] to reveal a [[NightmareFace creepy clown face]] and declare in the most disturbing voice ever, "I'm not Tommy!" before laughing insanely while the BackgroundMusic that plays [[ScareChord lets you know something's wrong]].

* There are moments of this in the episode "Real or Robots". It opens with Tommy and Chuckie [[KidsShouldntWatchHorrorFilms watching a movie]] about a {{mad scientist}} plotting world domination with his robots. Stu quickly turns it off.

* In "Stu-Maker's Elves", Tommy and Chuckie had to go down to the basement to get a fly-away frisbee. The basement was creepy, but the real nightmare fuel was a creepy first-person view of Chuckie's memory of being spanked by the doctors. We see Chuckie being held upside-down with his freakishly malformed and tube-like arms dangling beneath him, flying around franticly, and the loud "SMACK SMACK SMACK!" coupled with Chuckie bawling. It's probably the most terrifying thing to ever happen in the series.
* The episode "Under Chuckie's Bed" where Chuckie gets a new bed to replace his crib and thinks there is a [[ThingsThatGoBumpInTheNight monster under there]] and imagines that it's talking to him. When Chuckie dares to peek under his bed for the monster he actually saw a dark, demonic-looking humanoid WITH AN ARM REACHING TOWARDS HIM. This image is pictured above, by the way.

* Chuckie's germ nightmare in the episode "Mr. Clean". The faces that the germs wield do ''not'' help.

* "Pickles Vs. Pickles": Angelica appears to be suing her parents as revenge [[DisproportionateRetribution because they tried to make her eat broccoli and then sent her to her room when she lost her cool and threw the plate of broccoli against the wall]] and Drew almost gets thrown in jail. The scenery suddenly darkens as the judge orders him locked up and then the guards take him away from the court, with him kicking and repeatedly screaming, "NO! I'm a good father!" while everyone in the audience/jury ''laughs and cheers for Angelica'' and the camera [[EatTheCamera zooms in on his mouth]]... He wakes up immediately after this back in his bed. It was AllJustADream that Drew was having, but it's still a disturbing scene.
* The [[BullyBulldog vicious bulldog]] in the episode "Barbecue Story", specifically the part where Tommy and Chuckie are in the bulldog's yard searching for Tommy's ball and the dog growls at them, yanking so hard at its chain that it pulls against the dog house and ''[[SuperStrength pulls the dog house out from the ground nail by nail]]'' with the dog getting closer and closer to Tommy and Chuckie. Thankfully Spike comes along in a creepy voodoo mask of some sort and saves them.

** The scene where he wakes Tommy up by yelling, "RISE AND SHINE YOU SLEEPY HEAD, IT'S NO FUN TO STAY IN BED, [[RepetitiveAudioGlitch IN BED, IN BED, IN BED]], IN [[ElectronicSpeechImpediment BE-E-E-E-E-E-"]] is especially creepy because it takes place at night and ends with the uncanny, glitched voice.

** After the robotic Angelic is defeated, her [[YourHeadAsplode head explodes]], revealed a skull-like frame for her mechanical headpiece.

** Angelica's story that she tells halfway through the episode about a boy who got "eaten by a monster under his bed" is also quite disturbing too. It begins with the boy just laying on his bed and reading comic books, when he hears the monster talking to him. The monster tells the kid that he has cake and ice cream under the bed, and the boy, buying the monster's lie hook-line-and-sinker, [[TooDumbToLive drops down to the foot of his bed]], only for the monster to '''eat him alive in a scene that looks like it came from a ''Franchise/ANightmareOnElmStreet'' movie.''' Ending with [[BurpOfFinality a horrible belching noise]] to top it all off as well.

* The Passover special, with Angelica as the Pharaoh. If you're familiar with the story of Moses, the Pharaoh orders the first-borns to be killed. The fear sets in when Angelica's conversation with her father reveals that since she's an only child, that technically makes her a first-born.

* There are moments of this in the episode "Real or Robots". It opens with Tommy and Chuckie [[KidsShouldntWatchHorrorMovies watching a movie]] about a {{mad scientist}} plotting world domination with his robots. Stu quickly turns it off.

* [[ItsAWonderfulPlot "Chuckie's Wonderful Life"]], where Chuckie wants to [[TheRunaway run away from home]] when his dad's CD goes missing, and he sees [[ItsAWondferfulPlot what life would be like if he never existed]]. What was both terrifying and depressing was when his guardian angel showed him Tommy's dark, grey house, with a beaten, dirty and sad Tommy playing in the trash cans. The dialogue is as follows:

** The whole matter of getting injections in the first place, even without Angelica playing it up to be the most horrible thing ever. Adults can be terrified of needles too, after all. And as the doctor says at the end, some kids can take them, but some kids can't (granted, in this content, an inability to "take" a shot just referred to crying, but it's still creepy phrasing).

*** The climax of that episode, where [[ItMakesSenseInContext Tommy is in the bathroom]] and he keeps ''almost'' falling... It isn't scary as a kid, but to an adult, that whole scene is terrifying; what with the fear of walking into the bathroom to find your baby dead on the floor, with [[BodyHorror his skull cracked open]]. Oh- also, babies' skulls are very soft.[[note]]The soft spot at the back of their head goes away at two months, but a one-year-old's skull is still softer than an adult's.[[/note]]

** Babies are highly sensitive to cold temperatures and a cold wind can KILL them. Didi could have walked in to find that Angelica [[AccidentalMurder MURDERED]] her cousin.

** To couple with the above example in "Tommy Pickles and the Great White Thing", there's Tommy and Chuckie trying to plug up the bathtub drain with Play-Doh, Tommy climbing in and out of the tub and almost falling over! Two babies left unattended in a bathroom is always a terrifying thought.

* "New Kid in Town", where Tommy and his friends join up with this fat boy named Josh, who decides to play a game called "Pillow". He swings to the highest point he can and then tells the babies he's not trying to jump over them ...but he's going to jump ''on top'' of them. This kid looked [[FatBastard heavier than all four babies]] ''combined'', and he was going at least as high at the swing bar. Had it not been for Angelica intervening when she did, imagine what could have happened.

* "Toy Palace" had an actual working ''{{time machine}}'' (the Wee Willie Warp Time Translator) and a life-size toy robot got inside after hijinks ensued. It was transported back to the Revolutionary War in the middle of an ongoing battle with no way to return. Tommy and Chuckie, an ''infant and toddler'', could've ended up lost in the past forever in the middle of a '''''bloody battle!''''' Just imagine the trauma ''that'' would wreak on their innocent minds...
** Worse... with a robot toy from the future in that era, there might be an impact on the future. It showed up ''in plain sight'' during the war. [[FridgeLogic Maybe]] it caused [[EpilepticTrees alien paranoia...?]]
** What about the fact that it never said that there was ''any way of getting back to the present?''
** One of the toys was an electronic alligator that had a ''miniature fission reactor.'' What kind of toy store is this?!
** Arguably the most disturbing part of the episode is the security guard's ''blatant indifference'' to the fact that two infants were left behind in the toy store. Even when Stu and Chaz are ''pleading'' for him to help, the only thing the guard is even focused on doing is ''bragging'' about how good his security system is. Even after Chaz snaps at him, he continues to boast about its specifications!
