Nickelodeon may be a "kids network", but that sure as heck doesn't stop them from adding plenty of frightening moments all over place, whether it be in their shows or even their own bumpers/station ID's.

[[caption-width-right:350: NICKELOOOOOO-DEE-AAAAANNNNNN!!]]


Many of the network's earlier bumpers have been remembered as quite terrifying to young viewers, who are now old enough to use TV Tropes.

* The one most commonly cited seems to be [[http://www.youtube.com/watch?v=wdhQKrRw9kA the "Pinchface" bumper]], which features a [[NightmareFace creepy face composed of disembodied eyes and dentures]] that yells out the network's name (voiced by Creator/TomKenny) over a loud Balkan brass rendition of the Nickelodeon theme, all while seemingly having a seizure [[SensoryAbuse and inducing one to the audience.]]
* The [[http://www.youtube.com/watch?v=Jb3AgrXmLxU "Box"]] bumper is the unholy lovechild of said "Pinchface" bumper and Klasky-Csupo's 1998 logo (despite predating the latter by a few years) with Shrek ears. The entire thing feels like it was [[WhatDoYouMeanItWasntMadeOnDrugs made on LSD]].
* [[http://www.youtube.com/watch?v=xfbp8oI66Mo The "Compilation" bumper]] features characters and scenes from a lot of Nickelodeon's even older bumpers. While many consider this an awesome bumper, there's so much weird noises and crap flying at you that a few children were profoundly creeped out by it.
* To some, Face, the old Nick Jr. mascot, is somewhat unsettling. He's essentially a talking, Kirby-esque face that takes up the entire TV screen and makes weird faces and sounds. YMMV, some may find him cute.
* The "Egg and Spoon" bumper shows an egg turning into an UncannyValley monster that scares a spoon, which turns into a chicken scared out of its own wits. Then, the egg monster ''[[EatTheCamera eats up the entire screen]]'', leaving us with a CGI Nickelodeon uvula and a creepy, DarthWiki/DarthVader-esque breath.
* The [[https://www.youtube.com/watch?v=4q4Xaryg1T8 "Opera" bumper]], with a huge female opera singer wearing a humongois Nickelodeon-logo wig, along with a few [[GrossUpCloseUp close-ups of her face]], and the creepy-looking conductor and his face at the end as [[GlassShatteringSound his glasses break from the high note]].
* In October 2007, when the channel received a "Shocktober" theme, before and after commercial breaks they would show some rather unsettling images of Nicktoon characters done in a twisted monster movie style. Some of them looked mostly innocent, while others...fell a bit more into the creepy side of things. Examples included one image of Katara as an evil water spirit and a surprisingly graphic one of the skeletal corpse of Aang in chains.
* Similar to the one above, Nickelodeon update the bumpers for October 2016. Some bumpers were innocent [[note]] the [=SpongeBob=] bumper had him and Patrick turn into ghosts[[/note]], while some were pretty horrifying. An example is the bumper created for ''The Loud House'', where Lincoln tells the viewer that there's nothing to be afraid of... then we see his sisters eyes in the background, and Lincoln is still smiling.
* [[http://www.youtube.com/watch?v=S8YzSkLAbzo This]] 1986 Creator/{{Nickelodeon}} bumper (also shown in the UK during closedown) is creepy in its own rights, with wolves howling on a solid white background with an eerie noise.
* "[[http://www.youtube.com/watch?v=wlQNnX3phMY Sleeping Boy]]". The boy isn't scared by the fact that the Nickelodeon logo keeps stalking him throughout the bumper.
* [[https://www.youtube.com/watch?v=f48Of9zPkZc This]] bumper with mannequin silhouettes, [[EpilepticFlashingLights flashes]], and creepy minimal jazz music.
* [[https://www.youtube.com/watch?v=gseIizMw2ek This]] bumper has a coffee dispenser drink the tea with its nose, before its hair shrinks in and its skin dissolves, revealing 3 fish. This can be elevated for those who hate early CGI animation, because this and the aforementioned egg bumper are just abysmally ugly.
* Perhaps even worse than any of the above is "[[https://www.youtube.com/watch?v=0bjk33bE3R4 Nick is Kids]]". Nothing but a HeartbeatSoundtrack, unnerving sound effects, voiceovers with very long pauses, and dark images of Nick series and stars. It has been described as what would happen if Creator/DavidLynch made a Nickelodeon bumper.
* [[https://www.youtube.com/watch?v=DyFHCdKtFlc This one]] has very soothing music and creepy claymation kids that come straight out of the UncannyValley.
* While not aired on Nickelodeon itself, an ident on Nicktoons Network in 2004 named "[[https://www.youtube.com/watch?v=ze4URd3pwng The Dancer]]" could qualify. Its UncannyValley dancers that are always up in your face and the loud, fast-paced wonky music probably spooked more than a few younger viewers. The fact that it would air at [[ParanoiaFuel unexpected times]] during the commercials didn't help, and it can probably be considered a JumpScare for some who don't expect it. YMMV, as some may find it nostalgic.

!![[AC:Shorts and other Non-Ident Material]]

* [[http://www.youtube.com/watch?v=fdppYlhxltw Inside-Out Boy]]. YMMV, but the concept of the thing is just [[ParanoiaFuel a little]] [[AdultFear creepy]].
* Nickelodeon's ''Short Films by Short People'' showcased shorts created by kids, including one of which the kids who saw it on TV wouldn't forget: "[[https://www.youtube.com/watch?v=1JVo7p84u9U Attack of the Giant Vulture]]", which revolves around a giant vulture chasing three kids around Chinatown with the intent of eating them. Those who didn't find the short silly were terrified by the eponymous vulture (as the comments in the linked video will attest to), and even the short's ending (where the kids [[TheHunterBecomesTheHunted turn the tables on the vulture and eat him instead]]) comes off as somewhat disturbing, too.
* [[https://youtu.be/4Pd5dJSfQa8 A]] [[https://youtu.be/GeaYopeN38c Show]] of Hands. Namely the intro, where a group of disembodied black and white hands come together to form a NightmareFace with a deadpan voice--and yes, the hands move with the words. The rest of the shorts are actually not too bad, as they show a group of hands doing comedic sketches such as painting a picture or tying a present. But to say this short introduces itself poorly is putting it lightly.
