Pinkie Pie is bringing her big sister Maud around on a tour of Ponyville. While looking around Sweet Apple Acres, Maud loses her pet rock, Boulder. She receives help from Big Macintosh, and the two have a nice, deep conversation.

Thanks to RainbowBob for the idea for this ship.

Now with a Spanish translation!

The Rainboom happens as it should, and a few certain fillies earn their cutie marks because of it. Except little Pinkamena Diane Pie, who went inside before she could witness it. Thus, she never left the rock farm.

That meant she wasn't in Ponyville to throw that party that inspired a runaway colt named Cheese Sandwich.

However, the two end up meeting in adulthood, and the broke wanderer Cheese takes a job at the rock farm, and works alongside the grumpy Pinkamena and her family.

My take on an AU, created upon realizing that Cheese Sandwich was indirectly affected by the Sonic Rainboom. And in case you're wondering, the whole eternal night thing goes the same way as the show (except a different mare--whoever you imagine--wields the Element of Laughter).

If one would ask Pinkie on her work as a detective back on the train, she would say she had (in her words) a million, billion, gajillion years of experience, tracking down every sneaky pony down that did-done-dood it! But even the greatest detectives have humble beginnings, so where does hers start?

It started a long, long time ago, in a small rock farm, where Pinkie Pie was the lowly assistant to the greatest detective of all time.

Her sister, Maud Pie.
