Nightmare Fuel / Rocko's Modern Life

  • "YOU PUT ME IN A JAR?!"
    • Earlier in the episode, Rocko ends up in a closet full of organ jars, all of which have black holes for eyes and are all moaning "Don't cut us!" in a horrifying deep voice!
    • Rocko's appendix ''throbbing''.
  • The episode in which Heffer choked on a chicken bone and Rocko had to enter his body to find his heart and restart it. Of course, Heffer's insides were as creepy as could be, and his heart was a realistic heart.
  • Many of the rides in "Carnival Knowledge".
    • The aforementioned "Elevator to Hell" where said elevator rises, only to bump against the ceiling and plunge into the earth.
    • The "Saw Mill" where Rocko and Heffer nearly get chopped by spinning saw blades. The log they ride on even gets divided in half.
    • The "Nose Bleed", a roller coaster that's so high it takes its riders into orbit. Rocko's scream of terror and Wild Take before the train drops makes it even scarier. On top of those the coaster is unfinished with the track being built right at the bottom of the first hill!
  • The Hopping Hessian episode really did a good job of being surprisingly unnerving for a kid's show.
    • "Who took those pictures?!"
  • The episode "Who's For Dinner" had Heffer's house, which was a family of wolves who were carnivores. Carnivores who are eating what is obviously completely sentient food. Rocko opens up a mirror in the bathroom, which reveals three pigs being Bound and Gagged, and Rocko responds by merely closing the mirror to leave them to their fate.
    • There's also the room full of girls who look like Red Riding Hood.
    • Rocko slammed the mirror shut on obvious impulse and looked horrified at what he saw, which doesn't seem to fall in line with someone "leav[ing] them to their fate." He could, y'know, open it back up again.
  • Really Really Big Man's nipples coming into play.
  • Most of "Ed is Dead".
  • Mr. Bighead's vision of Heffer, Mrs. Bighead, and Rocko as devils in "Cabin Fever". "Are you okay, Mr. Bighead?" *shudder*
  • The crazy bus driver from "I See London, I See France".
  • The episode "Power Trip" where Rocko lets the power go through his head when Mr. Smitty goes on vacation. After hiring Filburt as a temporary assistant, Rocko pushes a literal Berserk Button in his boss' office that he was specifically told not to. Later on, the pressure becomes more intense for Filburt when he was trying to attend to the angry customers' needs and Rocko's as well. Eventually, Rocko was revealed to have similar features (i.e. portly physique, grouchy demeanor, etc.) to his boss, only with deranged eyes, much to Filburt's horror. If it weren't for Really Really Big Man calling Rocko out, the both of them would have horrible futures.
  • "Uniform Behavior", which pays tribute to The Shining. There's the twins-in-the-hallway scene which you can see coming a mile away, and then there's the scene where Heffer says he'd give his soul for a soda, and when the bill for said soda comes, it says "Payment: 1 soul".
  • The scene in "Love Spanked" where Rocko meets his date's father, who seems like a nice guy, but then he transforms into a horrifying grotesque monster saying that he will kill him if he even touches his daughter.
  • The scene in "No Pain, No Gain" when an ox gets his arms ripped off by arm crunchers with blood spraying from the stumps.
  • The smoking bluejay coughing up his heart in "Flu-In-U-Enza." Also a good Getting Crap Past the Radar moment as not only does it show someone dying, but it also shows a cartoon character smoking, something that has fallen out of favor in a lot of Western children's cartoons.
  • Three words with regards to the episode "Nothing to Sneeze At": Amphibial Globo Bloaticitis. It's a disease that basically causes your head to swell to three times its normal size (to the point of seeing veins) and appear like a huge tumor on your neck. This happens to Bev, much to Ed's horror when he wakes up smothered by her flesh.
  • In "From Here to Maternity," where the Easter bunnies have stolen eggs, and are seen whipping a bunch of baby chicks.
  • In the episode "Fish n Chumps" the scene with the crazy fisherman revealing his eye patch shows a cork in each eye can be a bit jarring, even Rocko and friends looked disturbed!
