Even with the quirkiness of the ''VideoGame/PaperMario'' series intact, this might just be the [[DarkerAndEdgier darkest game in the Mario universe.]]

'''Unmarked spoilers. Proceed with caution.'''

* The Underhands are disembodied hands that slowly pursue the player when they are in grabbing range. They are found either in deep water or in dark areas; in the latter, they are usually hidden away in out-of-the-way places, ready to sneak up on you.
* The River Twygz. Pretty tame if you stay near the surface; go any deeper and be prepared to encounter Underhands and [[https://www.youtube.com/watch?v=8LKHa7s1pD8 creepy music]]. The music has a bunch of garbled voices in the background.
* The FinalBoss, Super Dimentio, a monster that Dimentio created by merging with Mr. L and the Chaos Heart, a giant monster who has a fairly disturbing face that resembles Luigi's, and is initially unable to be harmed just like Count Bleck. And when he's defeated, he ends up being decapitated and still surviving for a brief period of time before his head explodes.
** And the theme music (of Super Dimentio) 'The Ultimate Show' begins close to Dimentio's own theme (AffablyEvil at its finest), before the music seemingly "cracks" to reveal the rest of the tune, a remix of the aforementioned Dimentio's theme, the Chaos Heart, and Mr. L.
* Mimi's transformation sequence into a giant spider. She ''twists her head entirely around'', ''Film/TheExorcist''-style. Complete with the sounds of [[{{Squick}} her spine cracking in multiple places.]], and grows extra legs with her head hanging upside down. If you flip while Mimi is in spider form, you can see the gears inside her, too. Even worse, in chapter 2-4, if you slouch for too long in an area while being chased by her spider form, ''she spawns at your location''. With the change of music, this can very well be a JumpScare.
* The first time you go into the Sammer Kingdom, it's increasingly obvious that the huge void in the sky is growing and there's not enough time to save the place after recovering the Pure Heart. What's even worse is that the inhabitants are completely aware of their imminent demise and even allow Mario and company to bypass the Duel of 100 in a desperate attempt to get the Pure Heart into their hands in time. The party doesn't even come close to getting the Pure Heart before they're forced to evacuate. You go back after it's destroyed, and all that's left is an endless [[WhiteVoidRoom white void]] with occasional debris. NothingIsScarier at its finest. And [[https://www.youtube.com/watch?v=IihQ5PlQRss the music]] makes it ''even worse.''
** Speaking of the music, there's the sound of a heart monitor ''flatlining'' in the background. [[spoiler:It makes sense in-game too, since the Pure Heart in this level has been turned to stone.]]
* Megabites, as well as their variations, are flying skull-like enemies that can randomly, and suddenly, appear in almost any level, with the earliest known sighting being 1-3, simply flying in from off-screen. While they aren't especially scary looking, there's a certain creepiness in their appearance, especially the basic Megabites, with their large, red eyes. Especially jarring is encountering them while 3D.

** And the theme music 'The Ultimate show' begins close to Dimentio's own theme (AffablyEvil at its finest), before the music seemingly "cracks" to reveal the rest of the tune, a remix of the aforementioned Dimentio's theme, the Chaos Heart, and Mr. L.

* The Underhands are disembodied hands that slowly pursue the player when they are in grabbing range. They are found either in deep water or in dark areas; in the latter, they are usually hidden away in out-of-the-way places, ready to sneak up on you. Although the game says they are invincible, they can be defeated by using Barry. In addition, lighting up a dark area will (temporarily) make them go away.

** Also, if you listen closely around minute 0:23 the voice appears to be saying "Save us, please!". [[SarcasmMode Have fun sleeping]] If you're hearing this late at night.
* The FinalBoss, Super Dimentio, a monster that Dimentio created by merging with Mr. L and the Chaos Heart, a giant monster who has a fairly disturbing face that resembles Luigi's, and is initially unable to be harmed just like Count Bleck. And when he's defeated, he ends up being decapitated and still surviving for a brief period of time before his head explodes. What about the concept of it in general? Luigi is the physical vessel for the death of the multiverse. As in every fictional world you've come to know even if completely unrelated, all wiped out. Including the non-fictional one, by the way. [[TheFourthWallWillNotProtectYou Yeah, remember how Merlon points out we exist, thus including our world in the equation?]] You'd never expect this from a series that people outside the fandom generally consider to be for kids.
* Mimi's transformation sequence into a giant spider. Feeling arachnophobic yet?
** It's less about the extra legs and more about the fact that she ''twists her head entirely around'', ''Film/TheExorcist''-style. Complete with the sounds of [[{{Squick}} her spine cracking in multiple places.]]
** If you flip while Mimi is in spider form, you can see the gears inside her. No one's sure if this makes it better or worse.
** Worse, in chapter 2-4 if you slouch for too long in an area while being chased by her spider form, ''she spawns at your location''. With the change of music, this can very well be a JumpScare.
* The first time you go into the Sammer Kingdom, it's increasingly obvious that the huge void in the sky is growing and there's not enough time to save the place after recovering the Pure Heart. What's even worse is that the inhabitants are completely aware of their imminent demise and even allow Mario and company to bypass the Duel of 100 in a desperate attempt to get the Pure Heart into their hands in time. The party doesn't even come close to getting the Pure Heart before they're forced to evacuate.
** As the dimension is about to be destroyed, the last Sammer Guy you encounter delivers one of the creepiest lines of dialogue in the game: [[DespairEventHorizon "HA HA HA. We are doomed. It cannot be stopped. HAH HAH."]] After the Sammer Kingdom is restored, you can learn that [[NightmareRetardant the guy's tendency to laugh is more of a nervous tic than anything else]], but it still doesn't detract from the line's sense of hopelessness.
** Then you go back after it's destroyed. All that's left is an endless [[WhiteVoidRoom white void]] with occasional debris. NothingIsScarier at its finest. And [[https://www.youtube.com/watch?v=IihQ5PlQRss the music]] makes it ''even worse.''
*** Take the following into account: ''THIS'' is the fate of anything that is destroyed by the void, and the void is also present in the Underwhere and the Overthere. That's right, '''not even the afterlife is safe from destruction.'''
* Megabites, as well as their variations, are flying skull-like enemies that can randomly, and suddenly, appear in almost any level, with the earliest known sighting being 1-3, simply flying in from off-screen. While they aren't especially scary looking, there's a certain creepiness in their appearance, especially the basic Megabites, with their large, red eyes. Especially jarring is encountering them while 3D.
* The fact that Luvbi is the final [[MacGuffin Pure Heart]] and that [[AndIMustScream she reverts to this for the sake of the worlds only to be stuck in a pillar somewhere in Flopside]] (then again the post-game reveals that she came back as herself, but still).
* After all is said and done, the [[TomeOfEldritchLore Dark Prognosticus]] is neither destroyed nor sealed away. Instead, it's simply said to have "[[NothingIsScarier faded back into history]]".
* Go back to visit Captain Gills the goldfish in subsequent chapters and not only is he bigger every time, but there are bones littering the bottom of the water. It's never specified what (or who) those bones belonged to.
