Doctor Whooves: Cutie Marks and the Daleks

Chapter 1
It was a nice day in Ponyville. Especially for the Doctor.
He had once come in his TARDIS and ended up in this world. But, entering this dimension forced his body to change it's shape. Kinda painful at first, but then you get the hang of it.

"Hey, Pinkie Pie." Said the Doctor passing Pinkie, on his daily stroll through town. "Hey, Time Turner." Said Pinkie.
Now, Pinkie thought the Doctor's name was Time Turner. Mainly cause he lied to her. He lied to everypony that his name was Time Turner.
"So, where are you going?" Asked Pinkie, curiously. "I am walking around town, patrolling for alie-" He stopped. He didn't want Pinkie to know his secret. "Uhh... Did I say patrolling? I meant walking..." Said the Doctor, nervously. "Well, I have to go!" Exclaimed the Doctor.
"Okay...?" Said Pinkie. "Really suspicious."

The Doctor decided to stop his patrolling. He had found nothing. If he did, Twilight and her friends would've stopped them.

Hmm... Thought the Doctor. Those ponies appear to be attempting to skydive. He watched as they jumped off. They were about to die! The Doctor ran as fast as he could. He pulled out his Sonic Screwdriver.
I need to save them, but how? The Doctor then saw a unicorn. Except, this was no ordinary unicorn. This was Twilight Sparkle.

"Don't worry, Time Turner." Said Twilight. "I got them."

The Doctor noticed her wings. I forgot she is a princess now. The Doctor stared as the Alicorn brought them down to safety.

"Now don't try that again." Said Twilight. "We just wanted our Cutie Marks." Said the yellow one.

"Apple Bloom, do you really think that is jumping off a cliff is the way to get your cutie mark?" Apple Bloom. So that's her name. What about the other two fillies?

"No, but we were trying to be Cutie Mark Crusader Skydivers..." Apple Bloom looked sad. "Come on, Sweetebelle, and Scootaloo."

Ah. Now it's coming together. Thought the Doctor. But before he could think more, a building right by exploded and knocked them unconscious.
