Derpy Whooves landed on the cloud that Rainbow Dash's house was on. Well, landed was putting it nicely. Crashed would be a more appropriate term in this situation. She had slammed face-first into one of the dense cloud columns supporting the house with such force, her head stuck out of the opposite side. She quickly pulled herself free of the column and shook her head, thankful that her worst crashes always seemed to be up in the soft clouds.
The mailmare giggled to herself at her own clumsiness, then walked up to the house's door. She knocked and fished out the letter for Rainbow Dash from her mailbags. She stood patiently, but was surprised at how long it was taking for the door to be answered. 'Maybe she isn't home right now,' Derpy thought to herself. 'Oh well, I'll just leave it in the mailbox.' Just as she was turning to do so, the door swung open to reveal a panting and excited cyan pegasus with a rainbow mane. Derpy was a little startled, but maintained her professionalism. "Hiya Rainbow Dash! I brought you a letter!" She said happily, using her trademark delivery line. On it was the crest of Equestria's most famous aerobatic stunt fliers, the Wonderbolts.
Rainbow Dash squealed with delight as she took the letter. "Oh, thank you, thank you, THANK YOU!" she exclaimed, wrapping the mailmare in a strong hug, before backing up and tearing open the letter. "I've been waiting for this letter forever! Ohmygosh, ohmygosh, ohmygosh, I'm so excited!" She calmed down enough to stop and read the letter out loud.
Dear Rainbow Dash,
On behalf of all of the Wonderbolts, I would like to thank you for taking the time to try out for the open position in our team. While we had many applicants, we are only accepting a hoofful of ponies for the official tryouts.
However, due to your excellent performance during the in-pony interview, I am happy to inform you that your application has been accepted. I will personally escort you to the Wonderbolts training area from Ponyville station in two weeks. You may bring along two friends to cheer you on during the tests. Please keep in mind that earth-ponies and unicorns will not be able to attend, due to the training area's cloudside location. Cloudwalking spells are not advised, as your stay will extend beyond the duration of such spells. We only wish to ensure safety of your guests.
I sincerely hope to see you in two weeks time at the station.
Truely yours,
Spitfire
At this point, Rainbow Dash was trembling with excitement, the grin on her face as wide as the skies she flew in. "That's awesome Rainbow Dash!" Derpy said, "Congradulations! Best of luck if I don't catch you at the station when you leave!"
Dash scoffed, "I won't need luck, I've got skill... But still... Thanks." She suddenly jumped into the air, and began performing all manner of airial acrobatics. Doing twists, loops, turns, and dives, all while shouting, "Woo hoo! I'm going to be a Wonderbolt! This is gonna be sooo awesome!" She dove down to the mailmare again and gave her a quick hug. "Thank you sooo much Derpy! You just made my day!"
"Oh, you're welcome Rainbow Dash," Derpy replied, smiling brightly at her cyan companion.
"I gotta go tell all of my friends about this," Dash backed up from Derpy and prepared to take off. "See ya Derpy, and thanks again." With that, Dash launched herself off the cloud and sped away, leaving a tell-tale rainbow in her wake.
Derpy sighed, content. "Another job well done," she told herself. "Now, let's see who's next. She pulled another letter from her mailbags and strained her wall-eyes to focus on the address. "Oh, it's a letter for Pinkie Pie! She's gonna be sooo excited when she gets it." Derpy quickly stored away the letter, and jumped off the edge of the cloud, gliding to her next location.
At Sugarcube Corner, Pinkie Pie was happily bouncing around, preparing for a big celebration party for Rainbow Dash. The pegasus had already flown by and given Pinkie Pie the news, and she was more than happy for her friend. The pink pony was zipping around the room, gathering her supplies, when she suddenly stopped. Her tail twitched, and her nose wrinkled up, without her doing it on purpose.
She hesitated for a moment, then gasped. "MAILPONY!" she cried, and rushed to the window to unlock it. As soon as she did, she stepped back out of the way, with a wide grin on her face.
Derpy's aim was a little less than perfect, as she flew, head-over-hooves into the second floor window of Sugarcube Corner. Luckily for her, the window was unlocked, and fell open easily when she hit it. She tumbled in, running on her two front hooves for a moment, before bringing herself to a stop right before hitting the opposite wall. She looked around the room to get her bearings, but Pinkie Pie pounced on her before she could.
"Hiya, Ditzy! I just knew you were coming because I got a twitchy tail, and then I got a wrinkly nose. And a twitchy tail means something is falling, but a wrinkly nose means something is flying, so I didn't really get it right away, but then I remembered that pegasi fly, and you're a pegasus, and sometimes you fall, but so does Rainbow Dash, but I had already seen her, and she couldn't be back already, so I figured it had to be you, and I thought, 'huh, if she's flying and falling, she'll probably fall through the window' cause falling through a window is the only way that would make any sense. So did you bring me mail? Huh? Didja, didja, didja?"
Derpy laughed at Pinkie's enthusiasm, and sillyness. She really liked this pony. "Yep," she said, "I brought you a letter!" She pulled out the letter addressed to Pinkie Pie, and gave it to her. "All in one piece, too! That's two in one day!"
"Thanks Ditzy! Oh, I absolutely LOVE getting letters! I wonder who it's from." Pinkie tore open her letter, only to find another letter inside, already addressed and stamped. She and Derpy both look at it in confusion for a moment, before Pinkie burst into laughter. "Silly me, I forgot I mailed this letter to myself so I would remember to mail it today." She gave the letter back to Derpy, who gave a quick glance at the address, then returned it to her mailbags, without any questions. "Thanks for the reminder, I would have forgotten all about it if you hadn't!"
"You're welcome Pinkie. Have a good day." Derpy turned around to hop back out the window she entered, and prepared to take flight again.
"Oh, and Ditzy, make sure you watch out for falling fillies by Applejack's house!"
"Falling fillies? Umm, okay Pinkie Pie, if you say so. I'll be careful." As soon as she finished that, she tripped out of the window and was lost from sight. A moment later she flapped back into view, giving an embarrassed smile to Pinkie. "Whoops, guess I wasn't being very careful, huh? But don't worry, your letter's still safe, and I'll make sure I watch out for those fillies. Gotta go!" And with that, she was off, headed to her next stop.
