The adventurs of doctor hooves and derpy

As the sun shined pasted the mountains echos of flapping wings pass through ponyville.

Twilight awakes to a laoud thud at her door "OUCH!" Said a high pitched voice emerging from outside. Twilight rushed to the door to see what happend. "Oh hi derpy" said twilight with a yawn, "hi twilight I have mail from the princess" said derpy rubing her head, "celestia wrote me a letter at five in the morning?" twilight said curiouslly "no not celestia, princess luna silly" derpy exlamed trying not to laugh. "what's so funny about thinking it was celestia wanting to see me?" Twilight said "oh I don't know the wrighter just put that in there" derpy said quickly, "wait what did you say" twilight daid curiously, "what did I say?" The two ponies stared at eachother aqwardly for a few seconds, "anyponie here's your letter" derpy said handing her the sky blue onvalope.

Twilight scurrys off inside to see what has hidden inside the letter, she opens the onvalope and reads to herself "dear twilight sparkle I need your urgant acistence at the royal castle I will explane later, from princess luna" twilight ponderd why would luna ask for her to help in a situation that she knows nothing about.

Twilight quickly packs a few dozen books on anything that can help in this mystirous event, and runs to the train station.
