Mailponies, the couriers of Equestria, carry important documents and packages back and forth throughout the land. Known for being kind, steadfast, and reliable, they are bound by a code of conduct detailing how to behave. In this code, an emphasis is placed on camaraderie between fellow mailponies. They are to trust, assist, and cooperate with each other whenever they can.
When mailmare Ditzy Doo finds an injured stallion by the edge of the Everfree Forest, she takes him under her wing. Upon waking, she discovers that he is, in fact, another mailpony, bound by the same creed as her. Through an adherence to the rules and the kindness of her heart, she allows the stallion to stay with her until he recovers. What will life be like for him under the Doo roof? More importantly, will he survive Dinky?
