History NightmareFuel / DextersLaboratory

* Mom's [[SanitySlippage slow breakdown]] in "Plsightly Psycho" leading up to a pretty creepy nightmare that can turn ''anyone'' into a germaphobe. The entire episode is basically what happens when a neat freak is told to relax and not clean, all while everyone around them makes a mess and barely noticing their sanity just ''shattering'' as they watch on.

* The episode "Star Check Unconventional"--basically a Star Trek parody. Dexter and his friends go to a convention center for a Star Check convention (the show's equivalent of a Trekkie convention), but due to distracting themselves talking about Star Check, the three mistakenly end up in a Darbie (Barbie parody) collectors' convention instead. Said doll collectors look and act very much like Klingons. Especially when one of the boys acts on sci-fi impulse and opens the box of a collector's item labeled "N.R.F.B." (Short for Never Removed From Box), which appears to be a capital sin around here. The expression on the other customers' faces is simply hair-raising. Said box contained a Darbie based on the American War Of Independence (the toy itself having been released during the U.S Bicentennial of the 1970's), and in a crazed state of mind, the kid thought he had to "free her" from her prison, not realising that it was a simple doll.

--->'''Dexter''': "It's okay, my sweet. Go back to sleep. You need your rest..."

** Really, Dexter's SanitySlippage and the utterly bizarre narration through the whole episode. It's meant to invoke GirlsHaveCooties taken to an extreme (the greatest danger inside Dee-Dee's room are literal cooties that look like weird insects), but it doesn't end there. Dee-Dee's whole room is portrayed as a twisted SugarBowl DarkWorld, filled with CreepyDoll inhabitants. At one point, Dexter is "attacked" by a girl doll that is somehow big enough to fall over him, covering him entirely with just its head, even though this makes no sense, as there's no way Dee-Dee would even own a doll that big.

* One [[https://www.youtube.com/watch?v=a-mHqaNCDho episode]], "Filet of Soul", started off with Dexter and Dee Dee's pet fish dying and Dee Dee refusing to let it get flushed down the toilet. Later, the ghost of said fish comes back to haunt them because [[NiceJobBreakingItHero he was denied entry to "the sewer beyond"]]. The ending parodied the classic ending from the "[[Music/MichaelJackson Thriller]]" music video.

** The way that mom says [[https://www.youtube.com/watch?v=8rO9fy134EI "Flush Him"]] in that episode is freakishly creepy.

* Dexter's Mom's mental breakdown in "Pslyghtly Psycho" can turn ''anyone'' into a germaphobe.
** The dust bunnies. DEAR GOD. ''THE DUST BUNNIES.''

** Anytime Dexter's mom gets angry, she's pretty terrifying, especially in the episode "Dee Dee Locks and the Ness Monster". It's no wonder why Dexter is unlikely to say no to her favors. Here's an example from the episode "Dexter Is Dirty":

'''Mom:''' [[SuddenlyShouting DON'T ARGUE WITH ME, YOUNG MAN!]] ''[[VoiceOfTheLegion JUST DO IT!]]'' ([[MoodWhiplash proceeds to walk off as if nothing had happened]])

* The episode "Jeepers Creepers, Where is Peepers?" featured Dexter and Dee Dee's magical friend Koosie working together to save Peepers (another magical being) from an [[EvilIsSexy anime villain]]. In one scene, we see a rather disturbing graphic look at Peepers as he is having his energy sucked off. HE'S INSIDE OUT. Also, he then ([[BigLippedAlligatorMoment somehow]]) goes from a BlobMonster to a flesh-colored [[OurDragonsAreDifferent dragon]] and fortunately stomps on the villain, [[FridgeHorror but how do we know that's not an effect from the machine he was trapped in?]]

* "Ewww, That's Growth" has Dexter trying to accelerate his body growth so he can be big enough to ride a rollercoaster. His experiment succeeds, but as soon as they arrive at the rollercoaster, they must go down an impossibly long queue, and by the end, Dexter's gotten much bigger than most of the other people waiting for the rollercoaster. Once an elongated Dexter finally gets on the rollercoaster and enjoys the ride, his head crashes into the upper part of a tunnel. [[GoryDiscretionShot The scene abruptly cuts]] [[NoEnding to a THE END card]]. And an uncomfortable feeling will most likely come over you.
** And yes, [[WordOfGod the episode's director]], Creator/RobRenzetti has [[https://twitter.com/RobRenzetti/status/1597436971080556544 confirmed]] that it's one of the episodes where Dexter is actually '''killed'''. Thank god for NegativeContinuity.

** Anytime Dexter's mom gets angry, she's pretty terrifying, especially in the episode "Dee Dee Locks and the Ness Monster". It's no wonder why Dexter, Dee Dee, and even their dad are unlikely to say no to her favors. Here's an example from the episode "Dexter Is Dirty":

** Not to mention that they get into an honest-to-goodness ''kaiju battle'', and while it's more funny than scary (Dexter and Dee Dee even [[CallingYourAttacks name the attacks they throw at each other]]), there's quite a bit of collateral damage to the city they're in. There are a few close up shots of their fight though, during which we actually see them ''bleed'' and Dee Dee bites Dexter. One of the worst parts though is at the end of the fight, [[TheBadGuyWins Dee Dee has beaten Dexter]] and he slowly falls backwards crushing buildings as he falls and people run for their lives, and Dee Dee just watches him fall with a PsychoticSmirk.
** Even before this there's something unsettling about Dee Dee's initial monster form, especially when she starts crying and destroying the lab…

* From "Aye Aye Eyes", there's the Creepy Eyed Girl's ThousandYardStare.

* The titular villain of "Simion" is nothing short of unnerving, especially regarding his backstory. Being the first monkey in space, his ship was hurtled into a belt of gamma radiation, via a crack in the hull which caused a horrific explosion. The ensuing radioactive exposure mutated the ape into what amounts to a god. Not just strong snd intelligent to the point of being able to speak, but can create matter ''by thought''. 50 years later he was poised to destroy Earth after being left to drift in space all that time, had Monkey not shown him that compassion…

*** The title card (pictured above) is also extremely scary due to featuring the close up of a bloody-red realistic eye, complete with the title being done in a Creator/TimBurton-style font.

* "The Old Switcharooms". The premise of this is that Dee Dee and Dexter break Dad's trophy and get sent to each other's rooms as punishment. Dad, however, doesn't just tell them; he gives them a lecture in [[TranquilFury a broken tone of voice indicating his rage]], [[TheUnSmile smiling all the way]] as though he's not so much disciplining as he is taking revenge on his kids over the trophy. Not helping is the psychotic background music and especially the shot where [[RedFilterOfDoom the entire screen is tinted red]] as it shows Dad's crazed eyes before he's seen furiously stomping towards Dexter when he protests. They also made Dee Dee's room - a room otherwise filled with harmless "girl" things - downright ''terrifying'', being mostly dark red and accompanied by a rather tense soundtrack, even [[TickTockTerror making the ticking cat clock ominous]] at one point. And then Dexter [[SanitySlippage proceeds to go insane]].

* "Chicken Scratch". [[AnimationBump The animation is more fluid]] [[UncannyValley (and downright ugly)]]. It really gets scary when [[https://www.youtube.com/watch?v=Uslw8e3VtKY Dexter crazily scratches himself, including on metal spikes at one point, and even destroys one of his robots to use its arm and head to scratch himself]]. It doesn't help that his maniacal laughter was lifted straight from "The Laughing".

* Puppet Pal Mitch, [[UncannyValley especially in the live-action skits]]. *shudder*
