My origin story for how Pinkie came to live with the Cakes is without a doubt my most popular story. It's simple and charming and I certainly get the appeal. I really haven't done anything MLP related in a while after finishing Pound and Pumpkin Tales, so I decided to go it big and transform my most popular story into a comic format.
This is a scene from chapter 3 of How a Pie became a Cake, but a few details shaved off to cut costs like the Cakes being there, Enjoy!
If you're wondering why the panels looks weird it's because Fimfiction now autosizes all comics so they're only as tall as your screen, so the only way to avoid that was to chop it up into 7 parts so it's shorter vertically.
