Some of you are failing hard at this. "The Great Muffin Caper - Spike has to help Pinkie Pie track down the walleyed pony who's been stealing all her muffins." Who WOULDN'T want to see this episode? Even if you hate Spike and Pinkie, it'd be worth it for the Derpy. "Let Me Stand Next to Your Dragonfire - Spike accidentally sends Twilight's private diary to Princess Celestia, and has to go to Canterlot to get it back before the Princess reads it." Not a fan of the title, but this is kind of an intriguing concept that could make for an interesting episode. "Blackscale the Pirate - A band of dragon pirates take Spike hostage" Dragon pirates? Do I even need to say how AWESOME that is? "Too Long, Too Cold - Rarity and Vinyl Scratch are stranded together during a snowstorm." A Rarity and Vinyl episode? BUCK YES! You guys seriously need to step up your game and make all the episodes actually sound bad.
I guess I better show everypony how to do this right:
Episode 1: Pandora's OCs Part 1 - The mane six go on a journey to find the legendary Pandora's Box, and halfway through the episode, they find it and open it. Equestria is flooded with OC's as a result. Deer horns, snake eyes, Homestuck hair, bat wings, exotic markings not seen before in the show, and eye-bleedingly horrible color schemes all become the norm as the mane six feel short due to the average height of ponies tripling.
Episode 2: Pandora's OCs Part 2 - Celestia and Luna are overthrown by a much more powerful Alicorn, who is then overthrown by an even more powerful Alicorn, and on and on. Chaos ensues throughout all of Equestria, as only a small number of these ponies are actually normal, not insanely powerful or hideous ponies. Both the Elements of Harmony and Cadence's love fail to stop these horrific monsters.
Episode 3: Pony Rewind: Bloodhooves the Death Master casts a spell on every non-OC pony in the show that begins to age them backwards. As the near the baby stage, they notice that they aren't changing into normal gen 4 babies. Their heads are bigger, their limbs slightly longer, and their eyes are much bigger. At the end of the episode, gen 3.5 Scootaloo wakes up from her dream, and tells her friends all about how "Friendship was magic".
Episode 4: Two For Tea: Pinkie Pie and Toola Roola have a tea party. Despite being capable of having a fully-functional tea party, they must still wear diapers because BABIES.
Episode 5: Portrait of a Pony: Toola Roola paints Sweetie Belle's portrait.
Episode 6: Gotta Go Fast: Rainbow Dash wants ice cream, but the refrigerator is all the way downstairs and on the other side of the house. She crawls as fast as she can to get it, finally obtaining and eating it at the end of the episode.
Episode 7: Shake Yo Twist Thing: G3.5-ified Twist shakes her booty for 22 minutes.
Episode 8: Scootaloo's Toy Train: Scootaloo receives in a package in the mail. It's a toy train. She proceeds to play with it.
Episode 9: Rainbow Dash's Fashion Show: Rainbow Dash designs outfits for everypony, helping them all learn to dress in style.
Episode 10: Starsong's Musical: Starsong performs a musical with her pony friends. (Note that Daniel Ingram is no longer the show's songwriter, as all of the DHX staff were replaced by the gen 3 staff as of episode 4)
Episode 11: Cheerilee's Story Time: Cheerilee reads to her little sister, Scootaloo.
Episode 12: Griffon the Brush-Off: It turns out Gilda was actually real, and she shows up in Ponyville. The events that follow are very similar to the Season 1 episode, with some changes: - Things are altered to fit G3.5. - At Pinkie's ending party, we see her leave shortly after Gilda does. The episode then focuses on the rest of the party-goers for a little while, and then Pinkie returns. Everypony is oblivious to the fact that she left.
Episode 13: Diaper Problems: Sweetie Belle is out of diapers, and goes to Cheerilee's diaper shop to get more.
Episode 14: Cupcakes Part 1: This episode plays out exactly like the fanfic does, only with G3.5 ponies. This time, nothing is altered to fit G3.5.
Episode 15: Cupcakes Part 2: Continuation of the Cupcakes story. However, at the end, there is a brief fade to black, then we see an autistic 5-year-old staring at the G4 and G3.5 ponies he holds in his hands.
