Fluttershy and Pinkie Pie have been married for a year or two.
The events of their wedding aren't important. What is is the fact that they want to prepare for motherhood.
And so, they ask if their friends would be fine with casting an age spell - and foal mind spell - on themselves. They agree. They'll keep the maturity of a mare - overall - but will act like a foal.
This won't end well.
Rated Teen for safety.
