Since the end of the last Summer Sun Celibration, the Ponyville Post Office has been quite the hub for delivering mail about the return of Princess Luna, and Derpy has been working hard with the recent flow of work. A normal day was about to end, when Princess Celestia came into the humble establishment, expecting not only a package, but requested Derpy Hooves to do the delivery.

What can go wrong?

Through wind and rain, down track and lane, Ponyville Postal delivers. No matter the weather, letters bring ponies together, and Ponyville Postal delivers.

Parcel Post faces his toughest assignment yet.

First day on a delivery job that pays on commission, Arthur Pinkles (known lovingly as Parcel Post) receives a letter with a cryptic address leading to seemingly nowhere. New in town and with no bits to his name he'll have to search for the enigmatic 'Discord' the letter is addressed to. Getting food at some point couldn't hurt much, though.

Pinkie will sit and wait right by the mailbox until she gets a letter from that marefriend of her's. After all she did promise to write to her, she always keeps her promises. If that the case, then why Pinkie heart breaks bit by bit everyday.
