"Thyberthonieth"

The Doctor and Rainbow Dash go on an adventure, kick metallic flank, save the day, and overall be awesome.

Now with complementary music!

When the Doctor and his companion Rainbow Dash land the TARDIS in the basement of the Canterlot royal castle, they discover that a whole bunch of robotic-like ponies the Doctor calls "Cyberponies" are hiding there, and seem to be up to something nefarious.
