- The very first plot had Dr. Sloth planning to hit Neopia with his mutation ray, turning every pet into a mutant. To make it worse, he captured the Space Faerie, the only being capable of stopping him.
- The Transparent color. This◊ is what happens. Sure, Invisible was literal... But this is what happens when your pet is permanently stuck in an X-ray!
- The entire Haunted Woods probably counts, if you go into detail... There's a tree with an exposed brain and a face there!
- The Web of Vernax game also has a rather menacing soundtrack, what with hunting Mootixs and all.
- There is a creepy animation for the Y8 Day Six of the Advent Calendar. A young Sophie the Ixi and her family are enjoying some holiday time at home. For some reason there is a distinctly foreboding theme playing to the cheery scene. Then three dark figures loom just outside the window...and there's a knock at the door. Sophie happily answers the door only to see three zombie Neopets looming over her. She looks up at them, horrified, then shrieks bloody murder. The gift for that day is a screaming Sophie toy. See it here.
- Back in the older days of Neopets, there was an incident where Maraqua was hit by a whirlpool. You actually could go in and see the entirety of Maraqua with a whirlpool scene over the top of it. It gave you a serious close up on what happened.
- Some of the Mutant forms can be kind of disturbing, but the Mutant Kau◊ takes the cake, especially compared to a normal Red Kau◊. It has tentacles coming out of its mouth!
- The Spooky Food Shop. It has a cute name but horrible wares. For example, the Blumaroo Steak, the description of which reads thus: "What goes bounce, bounce...whirrr....splat?" Then there's the several food items that involve Petpets. Let's not forget the pumpkin pie, either. Its description says: "Legend says that they used to make these pies out of something other than pumpkin in the past..." The Neopets Team horribly confirms that the Neopets sometimes eat food products made from OTHER NEOPETS, and some even eat Petpets! And it's not even necessary, since there are other foods in this shop that are perfectly fine, like Mashed Eye Potato. The Tyrannian Food Shop isn't much better. There is an item called "Mynci on a Stick", and it's apparently chunks of Mynci "roasted to perfection". The Lost Desert Food Shop also has dubious food items, most of them involving Petpets.
- Beware, all users with laggy computers, or who dare to wait between levels on certain games (looking at you, Typing Terror). You might be surprised by something...
- There is just something oddly creepy about most of the Advent Calendar animations and accompanying music.
- Were you expecting the uncased Robot Poogle to look like this◊? Yeah, didn't think so.
- The Haunted House. It's a Choose Your Own Adventure flash game from the old era of Neopets. Two pets are driving along a road during a storm and they break down right near a haunted house. All manner of horrible things can happen to the pets in the house: they can get turned to stone, turned into skeletons, caught by shadows and even Eaten Alive. If they don't leave their car, they see ghostly faces and if they still don't leave, you see their empty car before the scene changes to a police officer on the phone, stating that the pets were never found. The early era of Neopets was definitely dark.
- The loud sound effect that always plays when you lose Darigan Dodgeball and considering the type of game it is, losing is inevitable.
- The Jump Scare at the end of Lair of the Beast is the most famous example, and the current page image. It's just a pterodactyl that screams very loudly at you and can't do anything to your pets and/or account, but still. Oh, and you can get the same animation if you stop on a certain space in Wheel of Monotony, except this time it also can reduce your pets' health to one point. It's, unfortunately, the most common "prize", so expect to see this animation a lot.
- Back before the wheels' revamps, landing on the space that brings you to this will go to the page without confirmation taken, so imagine just browsing another tab while the wheel's going, and then all of a sudden... FRAAAAAAAAAAAAAAAAAAAAAA!
- The Malevolent Sentient◊ Poogle Plushie◊.
- Neopets: The Darkest Faerie has some pretty creepy places. This includes a maze-like dungeon towards the end of the game that has what looks to be execution chairs.
- Back when the site was run for college students, the NP Staff team did two contests where their avatars were competing in a Survivor-like game where their avatars got killed if they were voted off, and stuck in a murder mystery plot. While it was essentially meant to be nothing more than Black Comedy, the deaths got quite gory.
- The end of the murder mystery plot had the murderer revealed to be a robot controlled by Dr. Sloth.
- One of the TCG cards, Wocky Beast◊, features a bipedal Wocky with its face upside down and one gigantic swollen eye with no pupil! The only consolation is that his card is labelled as a Hero card, so he could be an example of Dark Is Not Evil.
They never went back to the fairground again, not after what they saw...
- The caption doesn't make it any better.
- If one really thinks about it, the Grundos' backstory as a Slave Race is a mixture of this and Tear Jerker. It's shown throughout the Dr. Sloth storylines that they are kidnapped, mutated, and brainwashed. They can, however, get a Happy Ending if you adopt them.
- The backstories of some of the villains are surprisingly chilling, especially for a kids' website.
If you look carefully at that old, disused chocolate factory on the hill, you may still be able to see this lonely Chia bouncing around, and you may still hear Wizzle's screams. Don't go inside however... whatever you do....
- The Jelly Chia. Basically, a crazy candy maker named Wizzle created an "edible friend" in the form of the Jelly Chia. He loved the little thing and took care of it...until Wizzle got hungry and decided to try and eat it. Instead, the thing jumped on him, devoured him and dissolved him alive. And then we get this lovely gem...
Always make sure your window is closed at night, because if you leave it open, you may not be there in the morning...
- The Shadow Usul, whose entry begins with this: "... creeping slowly up the wall, the shadow usul did not make a sound. The light from the moon illuminated the whole area, apart from a slow, crawling blackness, an area in which no light shone. climbing up to the unlocked window, the shadow flowed inside like a river of darkness..."
- Count Von Roo, whose entry is topped off with the epitome of Paranoia Fuel.
- The game Spell or Starve is about the malevolent AI Neopet v2, who is so lonely he's kidnapped you and forced you to play his new word game. After 3 days, you are on the verge of starvation and have no choice but to play along in order to escape.
- Xandra crashing Faerieland to the ground, changing the entire site forever. When you tried to visit before it was restored the game displayed the following message.Something horrible has happened...
- Jhudora's entry in the Gallery of Evil has her doing... something... to a Kacheek who had already failed her quest.
- This Story-Telling Contest about Jhudora taking over Neopia in a Bad Future."That's when Jhudora cast her ultimate spell. Historians think she had it planned from the start. Once she used all the other Faeries to take control of Neopia, she—she..." tears began to pour from the young Wocky's eyes.
"She what?!?" asked a frantic Jurgis.
"Oh, Jurgis!" Lerea cried, "She cast a spell to destroy all wings!"
"But, but... without wings!—" Jurgis stuttered in shock.
"Yes. The winged pets that had fought so valiantly-they... fell." Jurgis tried to swallow the lump in his throat, but could not. "They fell from the high clouds of Faerieland, and perished upon impact with the sea." Jurgis shook his head in horror. It was just too much. It was not only the Eyries that were extinct, but the Scorchios, Shoyrus, Unis, and Draiks, too! The Eyrie fought back tears; so many fine species lost—forever...
"Also, as I'm sure you know, if a Faerie loses her wings, she becomes a grey Faerie—stripped of all power. The Faeries that didn't perish in the sea with the other pets, just wasted away... even Fyora. Jhudora, as caster of the spell, was the only one not affected. With all the Eyries and flying pets gone, there was no way to fight her. Her throne sits in Faerieland now, but it's a dark cloud surrounded by a constant electrical storm. No ships will function near it, and no pet has wings to fly there anymore."
- Maybe not as horrifying as the others, but in the Cyodrake's Gaze plot, Orrin had been quite literally locked in the storeroom just before the storm hit. If the boat had actually sunk...
- Made worse by the fact that Captain Tuan seemed to have forgotten Orrin was down there, and didn't remember until the next morning.
- There is a random event that says that all your pets are sick and hungry, your items are stolen and your neopoints are all gone... but it's All Just a Dream. It's horrifying the first time you get it. Maybe not so much after that, but still.
- A Halloween Tale. DEAR. FUCKING. GOD! It may be the scariest story on the site to date. Just... what IS that old lady?!
- One of the fun images contains what seems to be a simple white Meepit, with only a blinking animation◊... until for a split second, it turns into THIS.◊ For anyone who isn't willing to click the link, it's a Meepit with elongated ears, a big disturbing stare, and a huge maw with a set of Scary Teeth.
- Petpets can get eaten by Turmaculus when trying to wake him up, or disappear completely if zapped with the Petpet Lab Ray.
- The Desert Abominable Snowball is a puddle with snowman features inside, implying the Snowball got melted alive. The only consolation is that they can still talk to your Neopets, which means that at least they aren't dead.
- The infamous Beast also appears in Bouncy Supreme. The game is about a jelly Blumaroo bouncing on pillars over a volcano to get away from it. If you lose all of your lives or run out of time, the game over screen appears and plays a loud roar, just as effective at jump scaring you as the Lair of the Beast. Not to mention the scare that comes with the concern for the fate of the Blumaroo.
- The April Fools' prank where everyone got The Scourgies, they even implied that Neopets could die from it.
- Edna is not (established to be) evil, and it was an accident, but her turning some Feepits into Feepit Pie is scary.
- There is also the rumor that she "smites" people who go near her tower.
- One of the phrases that Desert Petpets can say is "A CURSE ON YOU".
[Name of Petpet] starts to glow and shudder...
- Another spooky thing that Desert Petpets do is this.
- The Tale of Woe plot from Neovia certainly counts. A mysterious Snake Oil Salesman sells mysterious potions to the town-folk of Neovia, turning them into nightmarish and twisted monstrosities. Then there is the curse that the Spirit of Slumber cast on them...
- Another Jump Scare can come from the Snow Beast, which comes along roaring when you wait too long on Snowball Fight.
- Jhudora can be pretty creepy. Her Gallery of Evil entry states that while she hasn't done anything truly evil just yet, that's why she's creepy. Nobody knows when that's going to change, or how terrible her first malevolent action will be.
- The Awakened are an army of undead Neopets, led by creepy Wocky twins named Lanie and Lillie. It is implied that they themselves are Undead Children, and that they are responsible for doing away with other Neopets. Then there's dialogue like this, which is Played for Laughs but is actually disturbing when you really think about it:"Someone told us there was a war and we should go somewhere safe.""We ate him for breakfast. Yum."
- In a Neopedia entry about The Deserted Fairground an Acara is telling her friends a scary story around a campfire about the aforementioned attraction. The story goes that at sundown on Halloween Night the fairground comes back to life, looking pristine and filled with carnival workers. Visitors have to leave before midnight, or else, and the story doesn't leave anything to the imagination. Those who stay past midnight get eaten by the cursed carnival workers and all that's found in the morning is a ruined fairground and "wet earth beyond the gates". After hearing the tale, the friends decide to go see if the story's true, and surprise, it is. They play and then prepare to leave just before midnight. The Acara nervously asks her friend for the time but his watch has stopped. Then the gates ahead of them suddenly swing shut...
- The Neopets Team loves indirectly saying there has been violence while at the same time saying there's no violence. A book called "How to Teach Your Pet Not to Eat Everything They See Book"'s announcement description is as such: "It's been a while. You decide to check on your Pet. You open the door and oh not again! You better pick up this guide: How to Teach Your Pet Not to Eat Everything They See Book. You can get your hands on a copy at the Book Shop. And then you might want to grab some towels to clean up the spilled... milk..." 'Milk' is in bright red text, indicating blood.
- In the "Tale of Woe" plot, one of the puzzles has the player trying to open an old metal door with...something covering it. In the official solution for the plot The Neopets Team officially and insistently said the something was rust, but it didn't look like rust to some players. Later, after opening the door, the player finds the skeleton of a Neopet who'd died after being trapped inside. This is illustrated in the comic as well. The "it was rust" statement may have been an attempt by The Neopets Team to draw attention away from the plot's dark nature, or it was actually rust. Probably important to mention the skeleton of the pet above was from a nurse who worked in an asylum where all the patients went on a rampage one day and locked her in a room. A Neopet actually died.
