One Last Party Favor is one of the better-known Fan Sequels to Le Petit Four, itself a well-known Fan Sequel to the infamous My Little Pony: Friendship Is Magic fanfic Cupcakes (Sergeant Sprinkles).
The story begins with Twilight Sparkle researching a short string of bizarre disappearances. Spike is sent out to gather information, and notices suspicious happenings at Pinkie Pie's house. Pinkie Pie, believing that too much of her secret had been given away, gives Spike drugged food. He wakes up sometime later in a dark basement, and you know the drill.
The story is here.
Tropes:
- Axe-Crazy: Pinkie Pie until her memory gets wiped by Celestia.
- Big Damn Heroes: Celestia, who suddenly saves Twilight with telepathic powers.
- Lighter and Softer: It contains a great deal less Cold-Blooded Torture and Gorn than either Le Petit Four or Cupcakes (Sergeant Sprinkles)
- Not to mention that, in terms of mutilation, Pinkie only managed to cut halfway through Twilight's horn before Celestia arrived.
- Lottery of Doom: Just Like Cupcakes and Le Petit Four, Pinkie selects her victims using this.
- Scenery Porn: The fic's full of descriptions of the Torture Cellar.
- Why Don't You Just Shoot Him?: Subverted. When Twilight comes to save Spike, Pinkie just hits her on the head instead of feeding her cupcakes.
