The TARDIS door creaks open and the lights flash on, revealing a familiar brown stallion approaching the console.
"Well old girl, it's time. I don't particularly like his trip either, but it must be done. Allon..." The TARDIS interrupts him with a sudden, slow beep. "I know girl. Gallopfreyans aren't very welcoming when it comes to me. The Time Lords are even worse, and I have to speak with the Lord President." Rolling his eyes, he adds, "Fun."
A rapid knocking at the door catches the Doctor's attention. He approaches the door, but as soon as he begins opening the door, a blue colored mare pushes her way in and immediately stops, enamoured by the size difference.
"Wow Doc. How'd you manage to make the outside teeny tiny, and the inside super big?" The mare asks.
"What? Minuette?! What are you doing here?" He replies as he picks himself off the floor.
"You haven't returned any of my calls or letters, so I came to make sure you were okay. Are you okay?"
"I'm quite alright, but I must ask. Why did you barge in uninvited? I'm about to go on a big monthly trip, and I much prefer going alone." He begins typing in a set of coordinates.
"To me, "Big Trip" sounds like "Adventure," so I'm in." She leans back in a desk chair.
The Doctor shakes his head. "You misunderstand. I mean this is more of a regular visit to my home planet of sorts in which I must go to a meeting with the Lord President. I don't think she'd like it if I brought someone else with me."
Minuette calmly listens up until he mentions his home planet. "Wait. You're from another planet?"
"Correct."
"Why do you look like a pony then?"
That must be what this universe defaults to."
"You're from another universe?!"
"Yes I don't entirely know how I got to this universe though. In my original universe, I was a human. Tall bipedal beings with no fur"
"Aren't those the things Lyra babbles on about all the time?"
"The very same. Now if you insist on accompanying me-"
"I do."
"Then you'd better grab onto something sturdy. Things are about to get bumpy."
