Derpbooru Free Edition!?
I searched around a bit and couldn’t find any released episodes of the Pony Plot Perfection Project. The only thing I was able to find about the project was this official blog and the official forums for it. I have a feeling you already knew about those though considering you commented on it. If you want to try and find any episodes in the sources, good luck. I searched through them a little and couldn’t find anything saying there was an episode released.
