The Enigma

Chapter 3: Doctor Whooves

The Doctor opened the TARDIS door and jumped out. "Here we are Derpy, back in Ponyville."
"Yeah, we've come back here after every adventure, so it was pretty obvious we were coming here." Derpy walked out and stood next to The Doctor.
Suddenly, a purple maned filly ran up. "Hey, where did you guys come from? That box wasn't there a second ago, was it?"
Another pony ran up and said, "Buttercup, it was probably just our imaginations. There's no such thing as a teleporting box. Let's go look for Rainbow Dash."
The filly sighed. "Can we at least look inside the box?"
The Doctor quickly closed and locked the door, then said, "Oh, it's nothing interesting, just... A box."
"But... You were both in there, wouldn't it have been crowded?"
"Um... Buttercup... I think we should just go..."
"Uh, yes! It was... very crowded inside the TAR- the... the box." Derpy replied.
"The... Tar? It doesn't look like tar."
The Doctor exchanged a glance with Derpy. "Um, we have to go." The Doctor ran around a nearby corner into an alley, and Derpy followed close behind. "You almost told her about the TARDIS!"
Derpy lowered her head. "Sorry."
The Doctor sighed. "It's fine. I shouldn't have had the TARDIS teleport in plain sight during this time of day. We're lucky they're the only ones who noticed."
"So... What do we do now?" Derpy asked.
Um... I don't know." The Doctor thought for a moment. "Doesn't something bad usually happen soon after we get back?"
"Yeah, usually. Nothing bad has happened yet. Maybe we should go on another adventure?"
"We can't just jump to conclusions! We only just got back!"
"But when we just got back is usually when something bad happens! Remember? Nightmare Moon, Discord, That time we visited Canterlot and there were Changelings, it was all right after we got back from an adventure on another planet!"
"Usually doesn't mean always!"
"Well, yeah... I guess you're right. Actually, no. You ARE right."
"Yes. I'm also The Doctor."
There was silence for a while, until The Doctor said, "So, what shall we do while we-"
"HEEEEEEEEEELP!"
The Doctor's eyes brightened. "That's our cue!" The Doctor ran back out the alley, tracing the scream, and leaving Derpy behind.
"Doctor, wait up!" Derpy dashed out the alley as well, and looked around, but was unable to spot The Doctor anywhere. "Doctor? Doctor! Where'd you go?"
"HEEEELP ME!" At the sound of the second scream, Derpy caught something out of the corner of her eye. She turned to see what it was, and asked, "H-hello? Is someone there?"

"HEEEELP ME!"
The Doctor turned one final corner before bumping right into another pony.
"Ah! Get out of the way! It's right behind me!" He blurted out.
"What is? There's nothing behind you!"
"Wha- what..." He turned to look behind him. "W-where... Where did it go? It disappeared!"
"Ok... You need to calm down, and tell me what happened."
"Uh... O-ok... I was walking near the Everfree Forest, because it's part of my daily walking routine path, and a creature jumped out of the forest and started chasing me!"
"What did it look like?"
"Well, it had randomly appeared out of nowhere, and it kind of scared me, but even more so after it began to chase me!"
"Ok, but what did it LOOK like?"
"It had a spider-like body, and its head was a huge tentacle! That's um... All I remember."
"Well, I've never heard of a monster like that... What do you think, Derpy?" The Doctor looked around. "Derpy?"
