Princess Equestria pursues a magical MacGuffin, which is broken down into numerous pieces so I can crank out an arbitrary number of episodes before the ending. If I get sick of it and end it early, she'll just find a whole bunch of pieces at once. Pies explode and dogs don lipstick. Somepony gets whacked. A sowbug crawls across a desk.
Will Horsetaria survive? Will the Princess ever find a pair of pants that burn as brightly as the last ones? Will rubbing your nose vigorously make a piece of paper stick to the back of your head? These and other questions are answered! Somewhere.
