Chapter 3:
"But… We were just in New York!" Leo pointed out.
"I think I might understand how we got here," Donnie added. "That black- I mean… purple hole was actually something more like a portal."
Twilight nodded. "I'm very sorry. It's my fault you're here. I was just trying out a new spell that I discovered and-"
"Wait," Donnie interrupted. "Did you say… spell?"
"Yes. I study magic under the great Princess Celestia."
"Where we come from, there's no such thing as magic."
"Don't you have friends?"
"Yes, but what does that have to do with-"
"Friendship is magic! That's the reason I'm here in Ponyville. I study the magic of friendship."
"Speaking of friends…" Leo muttered. "I wonder where Splinter and April are. They were in the lair with us, so why didn't they come through?"
Donatello gasped. He couldn't believe he'd forgotten about April! He paced back and forth with his hands on his head, mumbling unintelligibly.
"You have funny names!" Pinkie Pie exclaimed. "And seriously, what are you? You look like turtles, but different."
"That's because we're not just turtles," Mikey, who had finally snapped out of his trance, offered. "We're the most awesome mutant ninja turtles in the history of the world!"
"We're the only mutant ninja turtles in the history of the world, Mikey," Raphael corrected.
"Exactly!" Mikey exclaimed.
"So…" Leo breathed. "In case you didn't catch all of our names, I'm Leonardo, this is Raphael, that's Donatello, and this piece of work is Michelangelo. Now… could you possibly get back to explaining how we got here?"
Raph rolled his eyes. "We're never going to get information like that! We should do it this way!" He gently set Spike down on the ground, then took out his sais and tackled Pinkie Pie, pinning her down.
"How did we get here?" he demanded.
Pinkie Pie giggled. "Twilight made a magic portal and we were going to go through just to get a looksie at where it went, but then you came through and the portal disappeared."
"Raph!" Leo exclaimed, running up to knock him off of the pony.
Mikey came over to help Pinkie up, but he wasn't needed. She was already up and bouncing, like nothing had happened at all.
"What Pinkie said is true," Twilight confirmed. "We were going to just get a peek at where the portal went, but something went wrong and it brought you all here."
"Well, do you think you could open the portal again and let us get back home?" Leonardo asked.
"I could try, but there's no guarantee that it'll open up in the same place as before. This spell is very unstable."
"Please, at least try. We have to get home."
"Alright. Just… Would you mind staying a little longer? I'd love to learn more about you and where you came from."
Leo looked around at his brothers. Mikey and Raph nodded, and Donnie continued to pace, oblivious to anything outside his thoughts.
"Donnie, we might be able to get back. Are you okay with staying just a little longer? April can take care of herself, plus she's got Splinter there."
Donnie looked up, then sighed. "I guess. It would be good to learn more about this place."
"Then it's unanimous. We'll stay just a little while, then go home. Or, try to go home, at least."
