This story is a sequel to The Rainbow's Surprise

On the day of Fluttershy and Rainbow Dash's wedding, Princess Celestia left Twilight a message saying that she should prepare herself if something happens. The next morning, Twilight awakens to find that all of Ponyville has succumb to a blinding fog. She must now travel a monster-filled town in search for her teacher and friends and try to return Ponyville back to the way it was.

No, not that kind of tank.

What really happened on the rock farm? She said "And that's how Equestria was made!". What in the world does that mean? Well, this story will tell you everything that went on at the rock farm before Pinkie moved to Ponyville, and what happened to her old family. Rated T for mild gore and graphic (bloody) scenes (for certain people).

One by one, Twilight and her friends must come to terms with the consequences of being the Elements of Harmony.

These stories take place in the intervening time between Season One and Season Two,
with the exception of Ditzy Doo: Muffins, which takes place early in Season One.

The series continues in the sequel, Secrets and Lies.

Set in an alternate version of the Ponyville we're familiar with, Cupcakes: The Musical blends elements of our favorite horror story with the musical fun of Sweeney Todd: The Demon Barber of Fleet Street. Here's the story:
This musical tells the story of Pinkamena Diane Pie, alias Pinkie Pie, who returns to Ponyville after 15 years' exile to the Everfree Forest on false charges. When she learns from her former landlady Rarity that her best friend has died, due the actions of the friendship-hungry Judge Twilight Sparkle (who's bought the "loyalty" of Rainbow Dash), she vows revenge in the best ways she knows: through baking and singing!

Credit goes to Stephen Sondheim and Hugh Wheeler for the 1979 musical from which the music is drawn and Sergeant Sprinkles for the story from which this draws inspiration.

Princess Luna must go on a diplomatic mission to the isolated city of Marem, and is tasked with choosing a suitable traveling partner to accompany her on the way. She does not choose the talented and magically-inclined Twilight Sparkle, nor the quick and loyal Rainbow Dash, nor even the strong and talented Applejack. Instead, she surprises everypony by taking Pinkie Pie with her and leaving without a word. Not even Celestia can guess the reasoning behind her sister's choice.

For whatever reason, Princess Luna and Pinkie Pie set off to find and negotiate an agreement with the mysterious community of unicorns located beyond the borders of Equestria. What they find there will impact not only Equestria's stance on foreign policy, but the very lives of the two ponies at the center of it all.

Twilight Sparkle just can't find enough time in the day. She has to study friendship for the Princess, hang out with her five friends, and juggle her own hobbies and interests besides. But when a novel solution presents itself in the form of an experimental new spell, will it solve her time crunch, or will she be distracted even further?

A thousand years is quite the generation gap, so Princess Luna decides she has to get with the times. However, this isn't quite as easy as she thinks it will be...
