The Tenth Doctor did not regenerate or die as suspected instead he is sent to ponyville as a pony now the Tenth doctor is given another chance at a happy ending. The tardis however is broken, can Twilight and Pinkie help the Tardis or will the Doctor be stuck in the same time and place forever? And where can they go if they fix it? What will Twilight and Pinkies friendships be like?
This story is also a litte random because pinkie pie random is the best in my opinion

In the introduction there is a explanation, but it's not who the Doctor is but I do explain it later. A little Doctor Who knowledge goes along way in this fanfic because I do not go over it very well.
