It will appear on Google Drive as a double feature with Thomas' Adventures of My Little Pony Friendship is Magic - The Cutie Map (Full Movie) in the near future.
Twilight's friends learn that she has been avoiding her castle because she does not feel at home there. The five offer to decorate the castle, arranging Spike to take Twilight for a day around Ponyville. In their first attempt, the five end up cluttering the castle with their own clashing styles. They try to remove pieces one by one, but only end up satisfied when everything is emptied out, making no progress. Realizing that they all miss Twilight's old home at the destroyed Golden Oak Library, the five fashion the tree's roots into a chandelier adorned with gems to remind Twilight of her old memories from Ponyville and inspire her to make new ones. Twilight returns to the castle and is moved by her friends' gift, finding that they have each also decorated a different room in the castle themselves.
