A short special taking place between the last Serial of the First Series and the Christmas (a.k.a. Hearthwarmer's Eve) Special, which I personally think is just a missing scene to fill in the plothole between those two episodes: How does Twilight (Rose in the TV Series) cope with a new Doctor? I really liked those six minutes I saw on Youtube, and wanted to convert that into Pony form.
P.S. The TV Series "Doctor Who" belongs to the British Broadcasting Corporation; I am not responsible for creating the crossover character (obviously), whose official name is Time Turner, as explicitly stated on the Time Turner/ Mayor Mare Trading Card, licensed by Hasbro. (They're still listening to fans, though; on the back, they say timey wimey!)
P.P.S. Like it? I might just write down the pony form of the entire New Series! But that's a "maybe" on my list . . . summer's ending soon.
