By now you've heard of Pinkie Pie. You have heard appalling things. I tell you this - She was a friend... and she was a seeker of Happiness. Of Laughter. The experiments... They were all part of her search for those things. All for the Element of Laughter. The elements of good and evil, which are inherent in every personality.

She became a brilliant pony. But she became a monster.

The arrival of a new "Star Buck's Coffee" in Ponyville is putting the pressure on Sugarcube Corner. The Cakes worry they'll soon be forced to say 'goodbye' to their bakery, until Pinkie Pie discovers a sugar-craving plant. Is this bizzare vegetation the bakery's saving grace, or will Pinkie Pie find it's growing appetite too much to handle?

A greedy corporate baron, a ravenous plant, musical numbers, and romance. Three of these four things are in this story, and since there's no shipping tag, you only get one guess.

Story is author-rated to be approximately PG (Nopony gets eaten or anything like that).

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

Just before leaving for her honeymoon, the newly-married Princess Cadance finds her old diary in her clothing dresser, filled with memories long forgotten, where she then recounts on those happy days as Twilight Sparkle's foalsitter. (Featured on EqD!)

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.

Hearth's Warming Eve has come once again, which means fun in the snow, warm food, and spending time with family. At least, that's what it means for most ponies. For Scootaloo it means a day off from crusading, loneliness, and the coldest night of the year. When Discord begins to whisper to her from his stone prison, she questions the beliefs held by many. What was so great about Harmony? What could be so bad about a world where chocolate milk fell from the sky?

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.
