Pizza Dash: When Rainbow Dash gets a job delivering pizza, she's forced to work all night long. She's even sleepier than usual during the daytime, and she has to miss several of Pinkie's parties. But the money's too good, and she can't quit. In the end, everypony involved learns about responsibilities and making time for friends when you have it, rather than forcing time for friends when you don't.
The Pinkie Package Plot: Pinkie orders something off of totally-not-eBay. Shortly after it arrives, things start going missing from Sugarcube Corner. Is the mysterious package to blame? And, more importantly, what was in the dang thing anyway?
Ding Dong Envy: Ponies from the next town over grow envious of the huge, ancient bell atop Ponyville town hall. They try to steal it, because they're a bunch of dickheads. Can Applejack, with "help" from the CMCs, put a stop to it?
Dragonslayers: There's already a few ideas for episodes with similar titles, so I'mma skip this.
Target: Spike: Spike grows convinced somepony has it out for him. He teams up with Owliscious, Angel, Opal and Winona to get to the bottom of the "conspiracy" (Gummy's busy doing something suitably weird), which turns out to be a bunch of coincidences.
Flutterage: Twilight invents a way of using Fluttershy's anger to power the town. She eventually realises, however, that deliberately hurting a friend's feelings is wrong, even if it's for the greater good.
Rainbow Smash: Rainbow Dash is cast as the heroine in an action movie. She grows arrogant (well, more arrogant than usual) over her newfound fame outside of Ponyville, and angry at the ponies of Ponyville for not giving a fuck, because Ponyville doesn't even have a cinema. Confrontations and yelling and making up, ho!
Twilight Twinkletoes: Twilight takes up ballet for...some reason, I don't know. She's not very good at dancing, but she's even worse at taking criticism. Eventually, she learns how, in time for a dance competition where she wears a bunch of accessories for Hasbro to sell to little girls, the greedy capitalistic fuckers.
