Imagine Ponyville, 40 years after Twilight became a princess. Pinkie Pie is still the same random pink bundle of laughter she always was, and the others are still doing what they've always done. Pinkie, by this time, has realized she cannot continue to spread happiness and cheer like she once could as her health began to decline, so she began to build a machine. This machine would carry on Pinkie's legacy and continue to bring smiles to the faces of ponies even after her passing. Pinkie pours her very heart and soul into the design and construction of this machine. How will those feelings reflect the machine's actions? Will this machine work as she had planned?
