3. Cupcakes
Fanfic Of: My Little Pony: Friendship is Magic
Plot: Rainbow Dash (the jock of the show's main ensemble) visits the bakery Pinkie Pie (the party character) works at when Pinkies alone. Rainbow is given a drugged cupcake and wakes up strapped to a slab in a room Pinkie Pie has decorated with organs made to resemble party balloons, streamers, etc. Pinkie herself is in a dress made of patches of skin from other horses. Dash is mutilated, gutted, and then killed by her cheerful friend in a prolonged manner presented with very graphic detail.
Commentary: Cupcakes may well be the most viral fanfic that has never been professionally published. There are countless
dramatic readings, several
comic illustrations, and people have even done
cosplays of it. On top of all that, it's been animated time and again. Not bad for a story written in
six hours which the author thought was a
botched job because he didn't include enough humor to offset the horror. Of the animations, by far the most fun and professional one is by MisterDavey. It's good enough that when he jokingly claimed that he is an
animator at Hasbro, people bought it: NSFW: https://www.youtube.com/watch?v=43AuJjuxqAw The most disturbing animation by far is an unfinished cartoon by Suppa. Despite the less-than-polished animation, the sound mixing and voice acting by Vannamelon more than makes up for it. It's also pretty much the only serious adaptation, with just about every other making a point of including the comedy that Sprinkles (the author) failed to include in his version.
