''One Last Party Favor'' is one of the better-known {{Fan Sequel}}s to ''Fanfic/LePetitFour'', itself a well-known FanSequel to the infamous ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''Fanfic/CupcakesSergeantSprinkles''.

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, [[Fanfic/CupcakesSergeantSprinkles and you know the drill.]]
