Dear Fluttershy:
I must say, your first attempt at terrifying your friends was rather lackluster. However, I did enjoy your little drawings. I had no idea you were into Japonese comics! You should consider working for an art company.
Also, that little smile of yours was absolutely adorable.
Even so, your second attempt was far more effective. I loved how that little monster that calls itself a rabbit managed to plan out every little detail to absolute perfection! I'll admit, I'm somewhat disappointed that your rabbit is so much better at this than you are, but I at least know that you'll always be able to count on him to save you from any awkward situations you may have in the future! Just make sure you let him know who you want to keep alive.
As for you, I think you should keep the vampire getup. It really gives you a dark and moody appeal. Just please don't add any sparkles.
Your friend, Discord.
Dear Fluttershy:
If you wanted to scare your friends, you should've invited them into your shed.
Sincerely, Princess Celestia.
Dear Twilight Sparkle:
My father, King Hasbro, was trying to have both holidays happen in order. However, there was a re-arrangement of the order of the episode schedule calendar, and so things got a bit messed up. Alas, this left us with some strange quirks, such as summer turning into winter which led to fall, but that's not something terribly uncommon. Calendar shifts happen all the time in this country. Remember how we ended winter two weeks before beginning fall last year?
On the plus side, the Cutie Branded Crusaders wore full-body costumes, so nopony questions the sudden disappearance of their cutie marks.
Sincerely, Celestia.
P.S.: Apparently some idiot didn't get the memo about the calendar shift, because we did, indeed, celebrate Nightmare Night at the proper time. And then we did it again tonight. Somepony's gonna become an astronaut!
Dear Twilight Sparkle:
You dressed up as me? You flatter me, you Trojan Whorse.
...Now could you please help me escape Celestia's fun-geon?
Sincerely, Flash Sentry.
