[Warning: this is an economical and caricatural reflexion without much humor]

Pinkie Pie was just enjoying a sunny day. But an encounter with the cutie mark crusaders and the leftovers of their latest creation lead her to build her own invention, the "Superpinkiastrolophilosothingything".

A pony comes and buys it, which Pinkie Pie accepts because it makes the pony happy and she loves making other ponies happy. But as other ponies come too to buy their own "Superpinkiastrolophilosothingything", Pinkie Pie begins to have some difficulty understanding what's happening and how to control it before something goes wrong...

Even if you could think this text is an economical satire, I have to warn you that this is just the way you interpret it. As for me, I just wanted to write about Pinkie Pie inventing the "Superpinkiastrolophilosothingything" and describe what purpose it had. If you want to be lectured, go see Twilight, that's her domain after all...Silly.
