Upon entering Pinkie Pie's dream, Pinkie Twi and Pinkie Shy find that Pinkie Pie and Vinly Scratch have a plan to save everypony - by combining their cannons and blowing away the changelings forever!
This is a joke chapter that was released for The Conquering of Love on March 31st 2013. It offers a ridiculous and abrupt ending to the fanfiction. Reading the original fanfic up to chapter 16 (Book 2 Chapter 10) is required if you want to even have the slightest clue what is going on. That said, it's a joke, so all you really need to know is that the ponies are trapped in dream worlds by Chrysalis and the changelings, and that Luna, Pinkie, and Vinyl have a plan to save the day!
Yknow, this would have been the perfect ending... If you couldn't write. Clapping ensues.
That... was... hilarious! Oh, poor fourth wall...
That fourth wall never stood a chance...
I loved the implication that this is not how the story was meant to end.
Aaaaand I died at this line.
I can't believe I haven't read this before.
