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 [[ the "Pinchface" bumper]], which features a NightmareFace made by floating dentures with floating eyes and glasses, which screams "NICKELOOHHH- DEE- AAAAHHHH!!" over an insanely loud disco rendition of the Nickelodeon theme. The face is voiced by Tom Kenny, but that is just a ''tiny'' amount of NightmareRetardant. Not to mention, [[SensoryAbuse there's all sorts of flashes all over the place.]] Who knew a 10-second {{Ad Bumper|s}} could be this frightening?
* The [[ "Box"]] bumper is the unholy lovechild of said "Pinchface" bumper and Klasky-Csupo's 1998 logo (despite predating the latter by a few years). The entire thing, like the "Pinchface" bumper, feels like it was [[WhatDoYouMeanItWasntMadeOnDrugs made on drugs]].
* [[ The "Compilation" bumper]] features characters and scenes from a lot of Nickelodeon's even older bumpers. There's so much weird noises and crap flying at you that children are likely to at least be profoundly creeped out by it.
* Face, the old Nick Jr. mascot, is somewhat unsettling. He's essentially a talking face that takes up the entire TV screen and makes weird faces and sounds.
* [[ Inside-Out Boy]]. YMMV, but the concept of the thing is just [[ParanoiaFuel a little creepy]].
* 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 ''eats up the entire screen'', leaving us with a CGI Nickelodeon uvula and a creepy, [[StarWars Darth Vader]]-esque breath.
