Stories currently in the Manehattanverse
The Wrong Place at the Right Time: Twilight is sent to Manehattan to oversee the preparations for the Summer Sun Celebration, and along the way makes several new friends.
Apples to Oranges: Orange Sherbet receives an invitation to the Apple Family Reunion. Now her friends have to help her remember how to fit in with her rural roots.
The DJ-PON3 Party: Octavia's old friend Vinyl Scratch invites her and her friends to attend a party. But this isn't the type of party Octavia's used to.
Brag You Down: Twilight has enough of Trixie's bragging and devises a way to knock her down a few pegs. However, there are unforeseen consequences that'll risk their friendship, and the city itself.
Hurricane Blossomforth: When Manehattan is offered to help Cloudsdale get water, all pegesi are to help out. So Daring Do and Blossomforth must help out the city using the water reservoir. In midst off it all, Blossomforth has a secret she can't tell which could put the whole event in jeopardy.
Badass Bookworm: In addition to Twilight Sparkle, there's also Professor Honey Do, AKA Daring Do.
Beam Me Up, Scotty!: When Octavia uses her cello to lull the chimera to sleep, she gives the oft-misquoted expression to Twilight: "Music soothes the savage beast." As Little Jackie Papercut points out, the actual expression is "savage BREAST."
Berserk Button: A subtle one that results more in annoyance than anger, but Honey Do doesn't like it when people compare her to her fictional counterpart.
Big "WHAT?!": A group one from the rest of the group when Orange Sherbet initially announces that she won't be attending the Apple Family Reunion.
Black Sheep: Orange Sherbet fears she's become this to the Apple Family. She's wrong.
Brick Joke: In response to the Beam Me Up, Scotty! above, when Twilight is explaining to Nightmare Moon how Octavia earned the Element of Kindness, she pointedly uses the correct version of the quote.
Chekhov's Gun: While at the Equestrian Museum of Supernatural History to check on the decorations for the Summer Sun Celebration, Honey Do shows Twilight "a few unremarkable lumps of rock." Once we learn in the next chapter that the Elements were moved to the Museum from the Everfree Forest, any fan familiar with the show can figure out what those rocks actually were.
Honorary Aunt: Orange Sherbet is insistant upon everypony referring to her as "Auntie." It's implied that this may result from her failed attempt to bond with Applejack. In Apples to Oranges, we learn that her husband Mosely Orange is very much the same way, insisting that Twilight refer to him as "Uncle".
I Am Not Spock: Pretty much sums up Daring's attitude towards her fictional self.
Twilight: "Next thing you know, (Trixie) will be given the key to the city just for fixing a broken cart wheel." (Cuts to Mayor Tux giving the key to the city to Trixie for repairing his Marecedes-Benz)
Koan: Octavia has a tendency to quote famous phrases.
Load-Bearing Boss: For the final battle, Nightmare Moon transports the Manehattan 6 into a pocket dimension fascimile of Manehattan that begins collapsing upon her defeat. Luckily, Luna is able to get them all out in time.
Shout Out: During her first visit to the Equestrian Museum of Supernatural History, Twilight is startled by a giant Jormungandr skin. Honey Do sympathizes, saying that she "really hates snakes." Also doubles as Foreshadowing since Daring Do is often presented as an Indy Expy.
When Nightmare Moon pulls Twilight into her pocket dimension, the Manehattan 6 get a good look at the portal:
