Christmas Eve, Ponyville
"Silent night, holy night. All is calm, all is bright" - Silent Night
It was Christmas Eve, the town was barren and dark with nopony in sight. Some would even call it a ghost town. Everypony was tucked away in bed, awaiting the next day with hopes that somepony would have come during the night and left gifts under their trees. This silence wasn't to last. Out of nowhere, at the stroke of 11:30 PM, the peace was disturbed by a distant sound. The sound was alien in nature, nothing in Equestria could have made such a noise. Nopony was disturbed though, they were all in a deep sleep. Suddenly, a new star appeared in the sky. It was moving! The star was moving, not left or right but towards Ponyville. The sound became ever louder, it almost sounds like engines. As it come closer and closer towards the town, it almost looked like a blue box.
Inside the TARDIS, over Ponyville
The TARDIS was filled with fire and smoke as The Doctor completes his regeneration.
"Ok, fingers! Where are my fingers!" yelled The Doctor, now in pony form "Well that's just useless! Oh my four legs and HUGE teeth!"
The Doctor tries to stand up on his four legs but the having the TARDIS in flight wasn't doing him much good. He reaches for the stabilisers while hanging onto the side of the console. With a flick of the hoof, the TARDIS adjusts itself and The Doctor is able to stand.
"Well that's taken care of" The Doctor said to himself "I swear there was something I'm forgetting"
Just as he gets used to his new pony body, the stabiliser lever flicks back and the whole room shakes
"Oh yeah! I'm crashing!" The Doctor shouted with excitement as he holds on to the console.
His voice was followed by...
Twilight's Library, Ponyville
An almighty crash followed by a loud yell wakes Twilight Sparkle from her sleep.
"Sweet Celestia! What was that!" said Twilight as she jumps out of her bed "Spike! Where are you!"
"What's all the yelling for Twilight" said Spike, giving her a confused look.
"Didn't you hear that crash?"
"No but it nothing to worry about, it's probably in your imagination"
"This is serious" yelled Twilight in frustration "This could be anything! Somepony might be in danger!"
She turns and runs out of the door. In the middle of the road there was a blue box with the words Police Public Call Box wrote on the top. The doors swung open, a hoof reached over and then another followed by a chestnut stallion with a dark brown mane.
"Hello!" said The Doctor with his head poking out of the TARDIS "Could I have so... OH MY GOD YOU'RE A HORSE!"
"No, I am not a horse. I am a pony and so are you" exclaimed Twilight
"Oh wow! This is amazing" he screamed "Not only have I landed in the land of the talking ponies but I have regenerated into one too. Fantastic!"
"No it is not fantastic, it's perfectly normal thank you very much" she said "Do you need any help?"
"Yes if you would be so kind as to pull me out" said The Doctor
"What's your name?" asked Twilight as she pulled him out of the box "I'm Twilight Sparkle"
"Very nice to meet you Twilight Sparkle, I am the Doctor" he said with pride, he then opened his mouth like he was going to be sick but instead of vomit, it was a yellow gas that disappeared after a few seconds "Oh excuse me, it seems I'm not done yet"
"What do you mean not done?" she asked
"It's simple... I'm... a... ti..." he said in a slurred voice then falling to the floor unconscious
"Spike!" yelled Twilight "Can I have some help over here?"
