Le Petit Four is a Fan Sequel of the seminally infamous My Little Pony: Friendship Is Magic gore fanfic, Cupcakes (Sergeant Sprinkles).
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 Fan Sequel in the form of One Last Party Favor.
The story is here.
Le Petit Four contains examples of:
- Anypony Can Die: Due to Pinkie Pie’s twitchy gut, and knowing the random nature of her twitches, anypony can really die. Except one.

- Cold-Blooded Torture: Pinkie saws off Rarity's horn, scalps her, tears off her tail, forces her to look at herself in a mirror, makes her drink Gummy's bath water, removes her hind hooves, skins her alive, and removes her organs.
- Cruel and Unusual Death: Rarity dies after an almost hour-long torture session inflicted on her by one of her best friends.
- Dark Fic: Like its predecessor, the fanfic contains high amounts of gore, contrasting the light-hearted cartoon that inspired it.
- Dark Reprise: An especially chilling example, as Pinkie begins singing while skinning Rarity, the tune she butchers being Rarity's dressmaking song, "The Art of the Dress".

- Instant Sedation: Rarity is knocked out by Pinkie's cupcake pretty easily.
- 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.Rarity: Please... don't do this to my little sister Sweetie Belle.
- She honours the promise.
- Anypony who read the Silent Ponyville Chronicles may feel especially sympathetic towards Pinkie Pie for honouring this specific promise.
