Le Petit Four

Le Petit Four is a fanfic sequel of the seminally infamous My Little Pony: Friendship Is Magic gore fanfic, Cupcakes.

The story starts with Pinkie Pie's twitchy gut "telling" her to invite Rarity to Sugarcube Corner to become a particularly fancy treat, despite Rarity thinking otherwise. Soon Pinkie drugs Rarity, and it all goes downhill from there, with a rather surprising yet in-character twist at the ending.

Le Petit Four also has a direct fansequel in the form of One Last Party Favor.

The story is here.

"Pinkie Pie: A promise is a promise, Rarity..."
 * Anypony Can Die: Due to Pinkie Pie’s twitchy gut, and knowing the random nature of her twitches, anypony can really die..
 * A Love to Dismember: Pinkie Pie kept Rainbow Dash’ taxidermised corpse hanging from the wall.

 * Beware the Silly Ones
 * Black Comedy: “Oh look Rarity, I got my beloved Moustache back!”
 * Cold-Blooded Torture
 * Cruel and Unusual Death: Horn removal notwithstanding along with everything else.
 * Dark Fic
 * Dark Reprise: An especially chilling example, as Pinkie begins SINGING while skinning Rarity. The tune she butchers? Rarity's dressmaking song, The Art of the Dress.
 * Even Evil Has Standards: Even if she is a cannibalistic serial killer, she will never break a promise to anyone, not even from her victims.
 * Evilly Affable: Pinkie Pie
 * Fallen Hero: Considering it's Pinkie Pie, Element of Laughter, yes.

 * Force Feeding: Pinkie forces Rarity to drink Gummy’s bath water.
 * Giggling Villain
 * Gorn
 * Grotesque Cute
 * Hero-Killer: Again, Element of Laughter upon Element of Generosity.
 * Heroic BSOD: Rarity's beautiful horn, mane and tail being removed would surely send her over the brink.
 * Hoofgore: Pinkie Pie takes the burning nails scene to the extreme, when she uses them to detach Rarity’s hind hooves.
 * I’m an Equitarian
 * Genuine Pony Hide: And it gets even worse when Pinkie Pie skins Rarity alive to make a dress out of her.
 * I Ate What??: Played straight when Rarity realizes Pinkie Pie made the cupcake she ate out of Rainbow Dash.
 * I Gave My Word: After killing Rarity, she honours her promise and  so she will not be killed.

"Rarity: Please... don't do this to my little sister Sweetie Belle."
 * Instant Sedation
 * Lottery of Doom: One of the first, if not THE first fanfic based on Cupcakes to expand upon the lottery idea with a more drawn-out process, involving a wall of all the ponies in Ponyville and a number for each of them, all mixed up in a hat.
 * MacGyvering: It's Pinkie Pie, and it's Cupcakes, her inventiveness remains.
 * Pet the Dog: What separates this fanfic above other sequels from Cupcakes, is when Rarity begs Pinkie Pie to promise her one thing.


 * Anypony who read the Silent Ponyville Chronicles may feel especially sympathetic towards Pinkie Pie for honouring this specific promise.
 * Pinkie Pie Swear: Even when cutting up Rarity, she repeats her Pinkie Pie Swear to honour Rarity's pleaful promise.
 * Pony Resources

 * Traumatic Haircut: Being Rarity, this is twice as traumatic to lose her beautiful hair.
 * Less of a haircut and more of a full-on scalping.
 * Vile Villain Saccharine Show
 * Vomit Indiscretion Shot: Rarity at one point ends up puking on the floor.
 * Water Wakeup: Right before Rarity falls into unconsciousness.
