This story is a sequel to On Getting to the Bottom of this "Equestrian" Business
A magical accident causes the personalities of the future Mane Six at the moment of getting their cutie marks to be swapped with those of their human counterparts during the Freshman Fair. They have only three days to figure out what’s going on and find the right individuals to help them: Princess Celestia in Equestria and the newly-arrived Sunset Shimmer on Earth. In three days the mirror portal will close, and anyone not swapped back will be trapped in the wrong dimension and body for thirty moons.

Note #1: This story is set in the same universe as my earlier novel On Getting to the Bottom of this “Equestrian” Business. I’m using the rules I established in that story for how the Equestria Girls setting works, but nothing from the plot, and since it’s twenty-five years later, you might as well start over with the characters anyway. That’s why I think you can read this story without having to read that earlier fan-novel first. Therefore, I’ll be including author notes as necessary to catch you up on those rules.
Note #2: I use “H” for “Human” or “P” for “Pony” before a character name to refer to the mind, not the body. So “P. Rarity” is the character that starts out in a pony body, suddenly finds herself in a human body, and struggles to get back into her pony body by the end of the story.
Note #3: For the human parts of this story, I refer to the “Freshman Fair”, an event that happened in the comics. All you have to know is that it was an event held during school hours at Canterlot High when Applejack, Rainbow Dash, Fluttershy, Pinkie Pie and Rarity were freshmen. It existed in order for the various school clubs to advertise themselves and gain new members, and it was at this event that Applejack and company all met for the first time and decided to become best friends. (Oh, and Sunset Shimmer as president of the yearbook committee later interviewed each of them about the event, gathering the facts she would later use to tear their friendships apart.)
