''[[http://www.fimfiction.net/story/1451/The-Monster-Mash The Monster Mash]]'' is a WesternAnimation/MyLittlePonyFriendshipIsMagic fanfic by [[http://www.fimfiction.net/user/FredMSloniker [=FredMSloniker=]]].

A collection of six {{horror}} stories revolving around members of the Mane Six encountering the supernatural. The stories are independent of one another and some are darker than the others. Despite the horror theme, the ponies remain very much in character and the optimistic tone of the series shows through.

The six chapters are:
* ''Fluttershy: The Curse of the Night'' - When Angel falls sick, Fluttershy ventures into the Everfree Forest at night to find a remedy. Though she faces danger, she escapes... but not unchanged.
* ''Rarity: Blood and Water'' - You know the story. Rarity gets seduced by a creature of the night, and her friends don't realize what's happening until it's too late. They find the vampire who turned her and destroy him. But then what happens?
* ''Rainbow Dash: The Big Battle'' - Discord's defeat didn't erase every trace of his influence on Equestria. Fortunately, hard-working ponies are already gathering the remnants of his power into Manehattan for easy disposal. What could possibly go wrong?
* ''Pinkie Pie: Gallows Humor'' - Pinkie Pie, Ponyville's premiere prankster, is dead. So why haven't the pranks stopped?
* ''Applejack: One of the Herd'' - Applejack may be in charge of Ponyville's biggest farming community, but that doesn't mean she can't take a break now and then. Besides, tonight's meteor shower should be even better than last night's...
* ''Twilight Sparkle: The Case of Wild Clover the Warder'' - It's a boring day in Canterlot, and Twilight Sparkle has time to kill. Maybe picking up an old lot of books will brighten her mood.

Despite the title, this isn't actually an example of a MonsterMash.

!!Tropes common to multiple stories:
* BigDamnHeroes: Occurs several times, most notably in ''Rarity: Blood and Water'' and ''Rainbow Dash: The Big Battle''.
* BittersweetEnding: Most of the stories leave the main character marked by their experience in some fashion.
* EarnYourHappyEnding: Much like the series itself, the ponies go through hell to get their (bittersweet) ending in most of the stories.
* ShoutOut: Several:
** [[spoiler:Ultradash]] in ''Rainbow Dash: The Big Battle'' is one to Series/{{Ultraman}}.
** Pinkie's reference to pod ponies in ''Applejack: One of the Herd'' is likely a ShoutOut to ''Film/InvasionOfTheBodySnatchers''.

!!Tropes appearing in ''Fluttershy: The Curse of the Night''
* BigNo: TheCavalry announces her arrival with one.
* TheCavalry: Played straight with the timely arrival of [[spoiler: Princess Luna.]]
* ChallengingTheChief: Twilight Sparkle's fight with the herd leader.
* NearVillainVictory: Twilight Sparkle faces the werepony alpha in a duel over Fluttershy's fate. In the course of this duel we discover that not only are these lycanthropes stronger and faster than normal ponies but magic resistant as well. Despite putting up an unexpectedly good fight Twilight is defeated. [[spoiler: And then [[TheCavalry Princess Luna arrives.]]]]
* OurWerewolvesAreDifferent: Aside from the obvious difference(they're wolf-ponies, not wolf-people), the werewolves retain their intelligence-the curse "just" increases their savagery. They're also inherently magic-resistant.

!!Tropes appearing in ''Rarity: Blood and Water''
* CurbStompBattle: The Mane Six are well prepared to take on Count Drache.
* EvilDetectingDog: She's not actually evil but, following her transformation, Rarity discovers that Winona doesn't like her. Opalesence on the other hand doesn't care.
* {{Expy}}: Count Drache is one to {{Dracula}}.
* FacingTheBulletsOneLiner: [[spoiler:'''Rarity:''']] "I only see one monster here."
* FriendshipMoment: Applejack defending Rarity from [[spoiler: the vampire hunter]], despite how uneasy Rarity's new condition makes her.
* HolyBurnsEvil: Holy symbols can block a vampire's powers and holy water burns them. Rainbow Dash takes this up to eleven by arriving at the confrontation with Count Drache pushing a rain cloud that was blessed by Celestia herself.
* KnightTemplar: The vampire hunter.
* [[MySisterIsOffLimits My Brother Is Off Limits]]: Not stated outright, but a significant source of the friction between Applejack and Rarity.
* OffscreenTeleportation: Pinkie uses hers to good effect against Count Drache.
* OurVampiresAreDifferent: Vampires in this story are weakened by sunlight, but not ''destroyed'' by it.
* StaringDownCthulhu: [[{{Dracula}} Count Drache]] attempts to use his vampiric mesmerism on Fluttershy. She meets his gaze with her own and it's the vampire who looks away.
* VoluntaryShapeshifting: Rarity gains this... sort of. She ''can'' turn into a bat at will at night, but discovers to her dismay that she ends up stuck like that during the day if she doesn't change back in time.
* WeakenedByTheLight: Although they don't burst into flames when exposed to sunlight, vampires lose much of their power in the daytime. Unfortunately for Count Drache, Twilight Sparkle has the sun on speed dial.
* YouDoNOTWantToKnow: Pinkie Pie keeps Rarity supplied with blood to drink. Rarity concludes that she doesn't want to know where Pinkie is getting it from.

!!Tropes appearing in ''Rainbow Dash: The Big Battle''
* AttackOfTheFiftyFootWhatever: The salamander [[spoiler: and Dash]].
* BehemothBattle: Pretty much inevitable, given this is an homage to giant monster movies.
* {{Kaiju}}: Giant monsters are the theme in this story.
* MutagenicGoo: The "chaos goop" left over from Discord's rampage.

!!Tropes appearing in ''Pinkie Pie: Gallows Humor''
* NoodleIncident: left unanswered throughout the story is the question of just how Pinkie died. But apparently it was spectacular.
* TakeAThirdOption: Rainbow Dash chooses this.
* VerbalJudo: Rainbow Dash, of all ponies, uses this to get through to Pinkie Pie.
* WhamLine: "Pinkie, this isn't funny anymore!"
* WoobieDestroyerOfWorlds: [[spoiler: Pinkie when she realizes that she's dead]]. Subverted, in that she's largely unaware of her rage awakening the undead and calms down.

!!Tropes appearing in ''Applejack: One of the Herd''
* AlienInvasion: Of the infiltration variety.
* DespairEventHorizon: Applejack crosses one when she realizes all of her friends and family have been taken over.
* GlamourFailure: Applejack can sense something is off with her family and friends, and she's also [[spoiler: immune to]] the spore's MindControl.
* PuppeteerParasite: The alien spores.

!!Tropes appearing in ''Twilight Sparkle: The Case of Wild Clover the Warder''
* BreakingTheFourthWall: Happens at the end.
* EpiphanyTherapy: Pinkie Pie provides this.
* FourthWallObserver: Pinkie Pie is shown to be this, and Party Popper is implied to be one. By the end, the spell has made Wild Clover and [[spoiler:Twilight Sparkle]] one as well.
* GoMadFromTheRevelation: This happens to Wild Clover and [[spoiler: Twilight]]. The latter gets better; we don't know what happened to Wild Clover.
* HumansAreCthulhu: [[spoiler: The reveal at the end.]]
* TomeOfEldritchLore: Twilight reads one of these.
* TheseAreThingsManWasNotMeantToKnow: Stated literally. Twilight's friends are all able to somehow tell that she's speaking in capital letters.
* WhamLine: The chapter ends with Twilight deciding to take a nap... before doing one last thing:
-->Turning to [[spoiler:[[TheFourthWallWillNotProtectYou look at you]]]], she said, "I guess I'll see you later, then!"
