The adventurs of doctor hooves and derpy

The doctor trots around the room while being followed by guards with there weapons at the ready. "what are you doing here" says Luna staring at the doctor "I have no clue" the doctor says with a smile " are you finding this amusing" Luna says with a tone in her voice "oh I am very amused, you know why?" the doctor exclaimed "no" everyone in the room says at the same time

"its because there's something wrong, and where there is something wrong there's danger and where there is danger.......I come" the doctor says while taking a breath.

At that moment the doors to the throne room open and a grey coloured pony with golden hair and eyes  walks in the room with a sack full of letters around her neck. "letters for the pri" she stops mid sentence as her crooked eyes draw to the doctor "doctor?" derpy says in excitement "derpy?" the doctor says in amazement. The two ponies look at each other in pure shock "you two know each other?" twilight says in confusion. "yes. she was my temporary companion a few years ago when nightmare moon attacked" the doctor says while looking back at twilight.

As the doctor looks a twilight he draws his attention to the window behind her. "now that's not good" the doctor says with a worried tone in his voice. twilight and Luna look outside the window to see a statue of a pony outside on the porch. "what is that thing?" Luna said looking back at he doctor. "that, princess. is a weeping pony".
