After saving Ponyville from the Cyberponies, the Doctor takes Derpy, Dinky, Vinyl and Octavia on their first adventure through time and space. Their destination; The Splendor, a massive cruise ship travelling the stars and powered by one. But, as usual, it doesn't take long for things to take a turn to the worst as the ship is overtaken by some hostile invaders with very nasty plans for the most amazing cruise ship in the galaxy. The Doctor must save not only his friends and the guests of the ship, but an entire world. The balance of an intergalactic war is on the line, and only the Doctor can save everyone.

No pressure.
