Plot Bunny Theater: Happy Birthday, Twilight · 12:37am Dec 8th, 2019
Every year, on her birthday, Princess Twilight Sparkle receives a visitor in a funny blue box. The Doctor, or Doctor Whooves. Every year, at the same time. They have tea, maybe a jump to another time or place, and then they return.
Finally, a thousand years after the events of the MLP Finale, Twilight finally asks the question.
Twilight: "... How do you do it?"
Doctor: "Hm?"
