As this is a Moments subpage, all spoilers are unmarked.
- "Mario's Nightmare", in which Mario has a nightmare where he is constantly killed by a dream version of Mama Luigi and other characters pop up to add to the effect and mood of the story. And there's a Jump Scare at the end.
- The climax of "Ghost Shrimpo". Woody goes to investigate a rustling in his closet late at night, only to get jumpscared by the titular "ghost shrimpo", a horrific fanged shrimp that lets out a terrifying shriek.
- Shrek grinding up Toad alive in the blender in Toad's Mistake 3! is both funny and disturbing. Poor Toad lives just long enough to feel the pain, and can be briefly heard crying after the carnage is over.Shrek: That was my cheesecake! How dare you?! THAT WAS MY CHEESECAKE!
Toad: TURN IT OFF! TURN IT OOOOOOOFFFFF!!! - Shrek making Mario slurp all his crap through a straw from the toilet in "Shrek's Crappy Wish!" is downright sickening, coupled with the noises Mario makes while struggling to get the dirty deed over with to get turned back to normal. The kicker? Shrek revealed that he made him do that just because Mario wouldn't bring him toilet paper for calling him "Donkey". Pettiness at its worst.
- The second half of "Bowser Junior's Sleepover". That is when Chica emerges from nowhere, murders Joseph and inflicts fear on Junior and Cody, just because Junior offended the game while he and his friends were playing it. Not to mention that she Jump Scares the viewer at the end.
- Charleyyy's description of kidney stones in "Bowser Junior's Big Mess!".Charleyyy: You see, a kidney stone is when you go and take a pee and it's like a rock, it just... comes out of your pee pee and it just RIPS IT IN HALF!
- "Cody's Sleepover" qualifies as well, since Chica and Bonnie appear in the video, and it doesn't even make anything better. What makes it worse is that at the end, Junior notices his Thomas the Tank Engine toy driving around, and then a scary-looking Thomas Jump Scares the viewer, in the same fashion as "Bowser Junior's Sleepover".
- Mario finding Shrek unconscious from a heart attack in "Shrek's Diet!".
- "Chef Pee Pee Quits! Part 5" is basically SML's take on FNaF. Anyway, Chef Pee Pee becomes the new night guard at Freddy Fazbear's pizza. When Chef Pee Pee walks around the restaurant because he's bored, he gets into the kitchen and finds two severed arms in a pool of blood. In fact, the whole episode is very atmospheric. There is no music, it's dark, and the only sounds that can be heard are Chef Pee Pee's talking and Freddy's music box.
- "The Drone!" has Junior getting his tongue cut off and Chef Pee Pee getting his eye ripped out.
- The Charleyyy and Friends skit in "Bowser Junior's Halloween Problem!", in where Charleyyy's baby gets turned into a monster, Chef Pee Pee tricks Junior into thinking that he killed his friends, and it ends with the Freddy Fazbear's puppets appearing out of nowhere in Junior's room to attack him.
- You can still hear them growling in the SML question, over the normal, cheery, "Get Outside" theme.
- And then there's "The Ouija Board!". This is considered one of the darkest episodes in the series, and for good reason. After Junior and Joseph insult the demons, one to many times, one of the demon possesses Ken. The supernatural horror is played horrifically straight, and the episode ends with the possessed Ken murdering everyone in the house.
- Bowser Junior catching rabies in the appropriately-titled "Bowser Junior Gets Rabies!", from his grotesque and bizarre hallucinations of Joseph and Cody to gradually breaking down and frothing at the mouth.
- "Joseph's House!", specifically the fact that Joseph has been raising himself for nearly a year in a run-down house since his mom died on October 31, 2015. He has left his mom's corpse in the place she died, he has no electricity or running water due to no one paying the bills, he has to steal money from his mom to pay for food, his pet fish and dognote are dead, his dad is a zombie (and becomes a ghost not long after), his roommate and only living companion is Screwball the Clown (who also does nothing to pay the bills), and somehow, Social Services is not aware of this.
- "Evil Chef Pee Pee!". Junior kills Chef Pee Pee by dropping a frozen water balloon on his head, and when Craig the Devil comes to collect his soul, Junior makes a deal with him to bring him back to life. Chef Pee Pee tries to feed Junior poisoned macaroni and cheese, then kills Bowser and Brooklyn T. Guy. It turned out this was a trick by Craig to teach Junior a lesson that his actions do have consequences.
- "Bowser Junior's Package!" shows how depraved and violent Junior has become, when he ties his dad up and decapitates him with a knife over a package he believed stolen'. Bowser's parenting may have created a monster...
- The ending to "Jeffy's Favourite Song!"; Mario wakes up in the middle of the night in pitch blackness, and a creepy, demonic version of the Hop Hop rabbit manifests itself in the doorway as the cheerful, upbeat music plays with an ominous undertone before it starts to sing the song in a low, demonic voice, dancing its way over to the terrified Mario, who screams as the rabbit reaches over, grabs him, then eats him with an audible, messy crunch.
- "Bowser Junior's 8th Birthday!" is not the type of birthday episode you would expect it to be, compared to "Jeffy's Birthday!". Because Bowser forgot to book a birthday party for Junior at Chuck E. Cheese's thanks to his short attention span, he gets Chef Pee Pee to book one at Freddy Fazbear's. Junior and his friends are served a pizza topped with eyeballs and fingers, the apple bobbing tank has an arm, eyeballs, and a brain inside, and Joseph, Cody, Chef Pee Pee and Brooklyn T. Guy get eaten by the animatronics, one of which gives a Jump Scare at the end.
- In "The New House!", Brooklyn T. Guy reveals that 26 people died in the titular house and the skeleton of the 26th person is at the front door. While also being Played for Laughs, when the group enters and admires the house, the skeleton suddenly tries to get inside, as Brooklyn tries to shut the door.
- "Happy Halloween!" has a big moment due to the killer clowns phenomenon. After a news report on this comes up on TV, Bowser freaks out and forbids Junior and his friends from trick-or-treating. Junior and his friends sneak out, only to be threatened by killer clowns, one of which kills Joseph.
- An incredibly ill Jeffy's eye falls off after he gets the flu in "Jeffy's Flu Shot!", much to Mario's horror.
- Jeffy getting his pencil lodged through his brain in "Smart Jeffy".
- Nancy from "Jeffy's Parents".
- For one, she is a chillingly realistic example of a child abuser. She is directly responsible for Jeffy's behavior, having beaten and tortured him for an unknown number of years, and deliberately abandoned him. Unlike other antagonists who, while evil and/or abusive have redeeming traits or are Played for Laughs, Nancy is played far more seriously.
- She's a smoking, alcoholic Gonk prostitute that was willing to spit on Mario for a dollar. Cue Mario screaming to be taken to the hospital when she does so anyway.
- "Netflix and Kill", where Junior and his friends watch a movie on Netflix named Netflix and Kill; Junior shows affections for the movie, confident that a "girl" shall interact with him, despite Joseph and Cody trying to prove that the movie can kill you. The horrible truth about Netflix and Kill is that it's the SML version of The Ring. Thankfully, there's a loophole: if the TV is paused, the ghost will freeze and cannot attack them. But then Chef Pee Pee, while on break, unpauses the TV...
- From "Joseph Moves In!", Joseph trying to kill Junior with a knife in his sleep. He writes "I'M SORRY MOM" on the wall in blood, and from his dialogue, it is heavily implied that he killed his mom just because she didn't make his sandwich the right way. "Joesph's Mom!" retconned this, but it was arguably worse then the original (see below).
- Hide And Seek: The Movie from "Bowser Junior Sneaks Into A Movie!". Just by looking at the thumbnail, you think Junior is going to watch a Doofy the Dragon movie, but the actual movie is about a seeker threatening to kill a hider. In fact, Junior and his friends get so scared watching it that they leave the theater.
- "Jeffy's New Toy!", where Jeffy accidentally watches an 18+ movie entitled Ass Pounders 2 and keeps talking about it. In order to shut him up, Mario tells him that if he stays quiet, he will get him a toy. While at Toys'R'Us, Jeffy finds a creepy doll, forces Mario to buy it for him, and names it "Areola". For some reason, Rosalina thinks that the doll looks cute. After Jeffy goes to bed, the doll causes a power outage. Mario ends up escorting Rosalina to the door and tries to look for Jeffy, and then the doll. While doing so, he finds really suspicious stuff, until it turns out that Rosalina has been playing as the doll all along. And there's another Jump Scare at the end.
- In the post-credits scene in "Bowser Junior's Big Spill!", we see the door as something is banging and banging on it, and after a hand unlocks it, the screen cuts to black as Brooklyn T. Guy says "I told you not to open that!"
- "The Secret Door!".
- We finally find out what's in the door—all 25 of the dead people, like theorized. Not just dead, but mutilated like something out of Hellraiser; it's so horrifying that even Jeffy realizes how horrifying it is. But then, we find out that, supposedly, Brooklyn T. Guy was the killer. And not only did he kidnap and threaten to kill Mario, Rosalina and Jeffy, but he also revealed that he was faking his jobs, and the people he murdered were the actual employees. Except that it was actually Brooklyn's brother, Does Bad Things Guy. Also, the reason why the door was banging was because someone was still alive in there, only to die as soon as Jeffy opened the door.
- Does Bad Things Guy. Everything about him (excluding his name) makes him without a doubt the most terrifying villain of the whole SML series.
- Unlike Nancy, Does Bad Things Guy is much more serious than the rest of the villains in the series.
- Second, the idea that Does Bad Things Guy has been impersonating his brother for months (who's to say he hasn't been doing that for the past years or so?!) is pretty scary on its own (especially since he is Brooklyn T. Guy's only identical twin and does a pretty flawless job of impersonating him), and that he has done this before.
- Thirdly, just his personality in general is enough to freak anyone out. Not only is he an Ax-Crazy Serial Killer, but it's also implied that Does Bad Things Guy is a necrophiliac. He's like a puppet version of Jeffrey Dahmer.
- Mario and Mama Luigi melting Toad's face on the stovetop in the 2017 remake of "Toad's Mistake!".
- Vladimir from "Jeffy's Brain!" might be as bad as Does Bad Things Guy. He's also a serial killer, but he doesn't use weapons because he prefers doing it with his bare hands and "eating their last breath".
- The killer shrimp from "Attack of the Killer Shrimp!" definitely qualifies. First of all, it's a repainted chestburster puppet, which is creepy enough on its own. Second, over the course of the video, it kills Brooklyn T. Guy's partner, his wife, and his dog, in cold blood. Lastly, it literally backs Mario, Rosalina, and Brooklyn T. Guy into a corner. If not for Woody's Big Damn Heroes moment, all three of them would be dead.
- In "Spoken", Cody makes a puppet of Ken to prove to Junior and Joseph that Ken can talk. It isn't long before Junior and Joseph aren't fooled, and an upset Cody makes a wish that Puppet Ken would come to life. Cody's magic wand brings Puppet Ken to life...then, as retribution for making fun of him, Puppet Ken kills Joseph in his sleep with a knife and tries to kill Junior. When Cody finds out, Puppet Ken tries to get him to join him, reminding him that Junior and Joseph regularly make fun of him and his mom. When Cody refuses, Puppet Ken tries to kill him and Junior, and in the end, Cody is forced to kill Puppet Ken by lighting him on fire.
- "Joseph's Mom!":
- It initially starts off as a normal SML Movie, with a few Big Hero 6 and Cody's mom jokes here and there, but then Joseph suddenly shows up, having dressed up as the guy who killed his mom. He then claims that he had murdered his mom with a hammer in his sleep after she grounded him and took his Xbox controller. As if that wasn't enough, Cody, not knowing what to do, calls Officer Brooklyn T. Guy on Joseph, and Brooklyn does an investigation at Joseph's rundown house, only to notice a price tag on Joseph's mom's skeleton, revealing it to be a fake. He then locates Joseph's mom, and she arrives at the house to tell Joseph the truth: after she had grounded Joseph, she realized that she had won the lottery and faked her death by buying a plastic skeleton, and eventually she abandoned Joseph to start a new life. After this, she disowns her son and leaves him behind. In complete denial, Joseph believes that his mom is just joking and goes home, while Junior can only watch in pity, as Joseph sits on the couch all by himself, waiting for his mom to come home and give him a big hug.
- Like Nancy, Joseph's mom was shown to abuse her son, although while she was a realistic take on an abusive parent, Nancy was just a grossly-exaggerated Hate Sink.
- "Jeffy Has Kids!": You would either find Brooklyn T. Guy eating afterbirth funny, or — when compared to real life — disturbing. It's just Cheerios afterbirth, but still.
- Jeffy's evil robotic replica in the episode of his own name, "Robot Jeffy" is uncanny, as it looks like T-800 wearing Jeffy's own corpse. It also tries to kill in a psycho-esque way.
- Brooklyn T. Guy's torture of Cookie Monster in "Black Yoshi's Call of Duty Loan!" after he tries to extract information on the whereabouts of his money. He gradually begins upping his torture methods as he gets angrier and by the end, Mario ends up receiving his severed head in a box as an ominous warning for Black Yoshi. Fortunately, Brooklyn puts him back together, but it's still a reminder not to mess with him...
- "Jeffy's Lunch Money!": Black Yoshi's Brooklyn T. Guy costume at the end is ... rather unsettling.
- "Jeffy's Foster Home!": Brooklyn's other twin, Makes Bad Decisions Guy is a spastic cannibal who lives with a hockey masked chainsaw wielding killer named Tim. That alone is terrifying enough, but attempting to cannabilize Jeffy for refusing to eat a severed arm, combined with the dilapidated condition of his house and the horrific abuse he puts the poor kid through, makes him even worse. It didn't help that Brooklyn put him there under the guise of "foster care" to try to scare him straight. The end result has Jeffy begging Mario to forgive him for his misdeeds.
- "Black Yoshi's BIG BAMBOOZLE!": After Black Yoshi steals money from Goodman's credit card by pretending to be the electric company, the unstable billionaire mails himself to the house and pops out of the box. At first he blames Mario and tries to bite his nipples off, but Mario successfully outs Black Yoshi as the scammer, at which point Goodman successfully bites his nipples off. No wonder why Mario fears him.
- "Jeffy and Junior Go To Prison!" is where... Well, Jeffy and Junior go to prison. No punches are pulled when they get to prison though.
- Their first two cellmates that Brooklyn T. Guy tries to find for them are old foes from previous videos; the first is Face-eater from "Jeffy's Pen Pal!", who comes very close to eating Jeffy's face off before Brooklyn rescues him and hauls him back off to the electric chair for the fourth time (while casually mentioning that the criminal ate three faces today). The second is David Winkle from the "1st Grade!" series, who nearly tricks the kids into falling for the "drop the soap" trick before Junior calls Brooklyn to get rid of him. It should be noted that Junior, unlike Jeffy, knows very well who Mr. Winkle is and was downright horrified when he learned he was their new cellmate, implying Winkle's time with him left a bad impact on him.
- Later, Brooklyn seperates the boys for trying to break out. Junior fares slightly better as his cellmate is Bubbles who actually decides to take him under his wing. But who's Jeffy's cellmate? Nancy, who wants Jeffy's blood and wealth as revenge for locking her up two years ago. Now, Nancy was already an abusive jerk in her debut video, but her pulling a knife on Jeffy to finish him off is downright chilling and shows how unhinged Nancy has become. Fortunately, Jeffy incapicitates her long enough for Brooklyn to announce their release, foiling her plans yet again.
- Did you think the puppets' designs were bad enough? Well, Junior and his friends' old puppet designs from "The Old Machine!" are downright cringe-worthy. Junior in particular looks worse then his mates.
- In "Cody's Robot!", Bott Buddy goes into kill mode after getting short-circuited with water by Joseph. He then burns Joseph's and Penelope's tests, and vaporizes Jackie Chu after Junior tells him to turn the test into the teacher. After going into "super kill mode", activated by inputting an incorrect button combination, he vows to Kill All Humans and shove a rolling pin up Chef Pee Pee's butt. Thankfully, Junior manages to shutdown Bott Buddy by pulling out his battery.
- The Easter Bunny in "The Stolen Egg!" is quite unsettling both in appearance and personality.
- Jeffy unintentionally killing a bunny in "Jeffy's Grandparents!" can be considered a disturbing mix of this and Tear Jerker, especially if you're sensitive to animals. Marvin and Rose's reactions don't help matters either, with even MARVIN sounding like he's on the brink of tears.
- Jeffy harming himself to appear "allergic" to vegetables in "Jeffy's Green Bean Allergy!". He bruises himself up with a baseball bat, leaving his face black and blue and his eye socket slightly popped out. Finally at the end, he CUTS HIS OWN EAR OFF in an intensely grotesque manner. Some compare this video to "The Drone" and a lesser version of "The Secret Door" in terms of gore.
- Even though it's Played for Laughs, the segment where Junior tests out a set of real-life human teeth in "Junior's Teeth" is rather uncanny at best. Even Brooklyn Guy is immediately unnerved and instantly regrets doing the operation and when Junior asks Joseph for feedback, the latter appropriately screams in terror. Not helped that the thumbnail has Junior with the human teeth in question.
- Nancy's final appearance in "Jeffy's 18th Birthday!" shows how deranged she really is: from hatching a plan to kidnap Jeffy with Screwball's help (though she accidentally captures Mario instead), to holding Mario as hostage and threatening his life if they don't give in her demands, and even showing how dangerously Genre Savvy she is by having the police meet her unarmed (Brooklyn's Loose Lips didn't help). Her final rant to Jeffy truly cements how psychopathic she is:Nancy: Jeffy, I'm sick of you! I never loved you, you were an accident. After I get my money, I'm gonna kill you and bury in the deepest hole I can find, and then I'm gonna kill your other family!
Jeffy: DADDY, HELP ME! - "The Huckerdoos!" introduce's Marvin's new titular neighbors. While things look all sunny and 1950's remniniscent on the surface, the moment the kids start singing their father suddenly loses his shit at them, revealing the insanely controlling person he is behind that pearly smile.
- In the end of the last two Jeffy Ball Z episodes, Brooklyn Guy steals Jeffy’s wish both times, but it also backfires both times he fights Jeffy, but at the end of episode 3, when he steals Jeffy’s wish for the third time in a row, he wishes for even better powers than his previous ones he got in the last episode, leading to this horrific moment:Brooklyn Guy: [after he gains his new powers] I feel the power this time!! I’m all powerful!! [unleashes attack] I’m a grower, NOT A SHOWER!!! [fires attack on Jeffy and presumably kills him]
Rose: OH MY GOD, JEFFY!!!
Brooklyn Guy: AHAHAHA!! I’M OVERCOMPENSATING FOR MY TINY PENIS!!! I'M GONNA GO RULE THE WORLD!!!!!
Marvin: Oh, Jeffy!! [he and Rose trying to wake their son up] Are you okay?! Please wake up, Jeffy! PLEASE WAKE UP!!!- Thankfully, in the next episode, it’s revealed that Jeffy survived and was just knocked unconscious.
- The ending of "The Grimace Shake!" is both a mixture of this and Played for Laughs. In the video, Grimace kills anybody who drinks the Grimace Shake. After Grimace tries to kill Junior, Brooklyn Guy is given no other choice but to shoot Grimace. The whole thing is done off-screen, which makes it a bit more jarring, as we're treated to nothing but the sounds of Grimace's final moments, the gunshots and Brooklyn Guy's anguished screams as he's forced to kill his best friend. Pablo and Anthony's voice acting in this scene doesn't help matters at all, making the scene all the more intense.
- "Attack Of The Nuns"; after Brooklyn Guy is shot in the face, one of the titular nuns shows Brooklyn's corpse directly at the camera, showing his bloody blown up face.
- When you have videos based on horror game Five Nights at Freddy's, it leads toward this range, as Jeffy and Brooklyn serve as night guards, and it is what you expect from the Five Nights at Freddy's games, the animatronics attempt to kill them with their usual method.
- Part two of the series involves Marvin joining Jeffy and Brooklyn in serving as night guards, Marvin ends up receiving the short end of the stick during the night, and by the end of the video, Marvin is completely traumatized from being there. Doesn't help that the video included a jumpscare on the SML question part.
- Part three of the series is arguably the darkest one in the series so far, due to its more in-your-face jumpscares and the backstory. In the video, it is revealed that Springtrap was Mr. Winkle and explains that a long time ago, he dressed up as Springtime Bonnie and killed five children in a blind rage after being refused a hug. What makes matters worse is that one of them Died on Their Birthday and the deaths are shown off-screen, leaving their deaths, other than their terrified screams to the imagination. Most likely, he killed them by throwing them to the floor at full speed face first. And for each slam, another kid stops screaming until no more screams are heard. Wow.
