One-Shotober Story #2 10/2/2013

When Trixie's brand new wagon breaks down in the middle of Hoofington, she finds herself unable to repair her broken wheel herself. So she decides to call upon Equestrian Roadside Assistance for help.

It will be a decision she is doomed to regret as she is forced to confront automatic voice directories, unhelpful operators, intolerable hold times, lovecraftian madness, gastrointestinal distress, and moronic protocol.

Trixie will never leave Hoofington with her sanity intact.

(Inspired by events that happened to the author)

Trixie's line of work is dangerous. But she's a careful showpony, and that's why she's only died a few dozen times in her career.

She thinks this is normal.

Twilight Sparkle flagrantly abuses her Come-To-Life spell, and learns a little bit about love in the process. Also, puns.

Now with actual cover art, thanks to the generous SuddenlyFerrets!

Now with a Spanish translation by Spaniard Kiwi!

When Apollo 11 lands on the moon, Neil Armstrong utters his famous lines as his boots land in the lunar regolith, but when he turns around he finds something no one was expecting or had ever planned for.
There's an alien on the moon. And it's blue, four-legged, and staring at him.

Sequel here.

A crossover between the popular, deranged Youtube series Charlie the Unicorn, and My Little Pony: Friendship is Magic.

Charlie, in his quest to rid himself of a pair of pesky unicorns, finds himself in Ponyville. The mane six give him a warm welcome, not knowing a certain pink unicorn and his blue counterpart are waiting on the wings... How will the Ponies react to these logic-defying Unicorns?

Charlie the Unicorn, and all of its characters, are property of "FilmCow". My Little Pony: Friendship is Magic, is property of Hasbro, I claim no affiliation with either.

Note: I seriously recommend you watch the Charlie the Unicorn shorts on Youtube before attempting to read this fic. It will help give you a scope into the nonsensical world I am attempting to convey here. I think I gave myself permanant brain damage attempting to type this...

Edit 20/7/2013: As of Episode 4 this fic is now even less canon.

A secret unknown to any hornless pony, unicorn horns are made of candy. Pinkie Pie found out, and now she wants to try every flavor!

Warning: contains awkward moments and far too much non-consensual horn licking. Proceed at the risk of your horn and your dignity.
