Trick or Treat?

Dear Rainbow Dash,

I'd like to invite you to spectate a magic competition at the Golden Oaks Library. Please meet me at two o'clock sharp on Tuesday, the fourth of December. Thank you in advance!

- Twilight Sparkle

Dash squeaked when she saw the letter fall through her mailslot. "Eeek! It's from Twilight! Maybe a new Daring Do book came out..." she wondered as she tore open the envelope. It was addressed to "Rain Bow Dash XXV, Cloudly Lane 1052" and the return address was "Twiletta Sparkella Admira, Palace Avenue 7703". It fascinated Rainbow that Twilight would use her full name, in the old-world style as "Rain Bow".

Twilight swiftly filled out letters, each address different. Spike was outside near the Town Square, telling all the pegasi and earth ponies about the contest. Back at the Library, she panted a little and moved the letters past her eyes as she checked each address; "Colgate Tel Flozz, 9093 Chomper Ct", "Rarity Silvershine, 4003 Carousel Blvd", "Berry Punch, 3600 Elder Avenue", "Night Quillfeather, 4431 Bluesnow Blvd", "Lyra Heartstrings, 4400 Count Dr", and finally "Sunstar Filre, 3690 Emotional Aria Ct". She closed her eyes a little disappointedly; there weren't many unicorns in Ponyville as there were Canterlot. Nevermind, she chided herself, it's fine. So what if 92.5435678.23455x4 ponies in the town are earth ponies.
