Fluttershy was walking nervously toward the Castle of Friendship, her friend Twilight's home. After defeating Tirek in an epic battle, as Rainbow Dash would say, Twilight's crystal castle had appeared from beneath the ground and rested in the center of Ponyville.
"Whoa, is that where your friend lives, Miss Fluttershy?" Junior asks. "It looks amazing!"
"It is very nice, Junior. It's probably best though to stay hidden until we reach the castle. We don't want anypony to find out what you really are." Fluttershy said in a quiet voice.
"Hi, Fluttershy!" Carrot Top said, catching the pegasus by surprise.
"Eek! Oh, um, sorry! You just startled me, Carrot Top." Fluttershy said, catching her breath.
As Fluttershy calmed down, Junior peeked through his disquise to catch a glimpse of who Fluttershy was talking to. Carrot Top was a light yellow-coated pony with an orange mane and tail. Her cutie mark, as the ponies called them according to Fluttershy, was a set of three carrots.
Carrot Top then noticed Junior peeking out from his disguise, prompting the Edmontosaurus to hide himself once again.
"Oh, who's this little fellow?" Carrot Top asked.
"He's, umm, my nephew." Fluttershy said, sweat dripping from her forehead and nervously smiling.
"Oh, so you're brother finally found someone." Carrot Top asked.
"Uh-huh, and he's sent over his son to spend some time with his aunt." Fluttershy nervously chuckled. To prove this, she pulled her 'nephew' in for a hug, a very awkward hug to be honest. Fluttershy was very nervous about this since this was the first time she ever lied to someone.
"Would the little one like a carrot? Its on the house." Carrot Top said, cheerfully.
"Umm, sure." Junior said, quietly.
"Aww, are you a little shy, sweetheart? You're just..like...your aunt." Carrot Top said, but notices Junior's Edmontosaurus reptilian paw reaching for a carrot.
Before the carrot salespony could say anything else, Fluttershy quickly pulled Junior into the castle.
"Huh, weird." Carrot Top said and went on with her day.
"Alright, I just need to concentrate and all be able to perform this spell." Twilight said, calmly. She finished reading the steps on the scroll and got herself ready. Twilight got into the position needed for the spell and began meditate. As she did this, her horn began to glow with magenta-colored magic.
The spell was almost complete but before she could finish it, Fluttershy burst through the door. This caught Twilight by surprise, causing her to lose focus and all her magic to go away.
"Sweet Celestia, Fluttershy! You almost gave me a heart attack!" Twilight exclaimed.
"O-Oh! S-Sorry, Twilight. I can come back another time if you want." Fluttershy said, nervously. Junior, under his cloak, nudged Fluttershy forward. "Oh, actually, we need to talk right now. It's something important."
"Alright, Fluttershy. What is it?" Twilight asked. Twilight then noticed Junior hiding behind Fluttershy.
"Uh, well.." Fluttershy started to say and then slowly revealed Junior from his cloak.
"Wha-That's a-Oh, Celestia, I don't feel so good." Twilight said, before she passed out.
"Uh oh." Junior said. Suddenly, Spike, Twilight's dragon assistant and little brother, walked through the entrance carrying some groceries.
"Hey, Twilight! I got the stuff you asked fooooooorrrrrrrrrrr...WHAT THE TARTARUS IS GOING ON?!" Spike exclaimed.
After waking Twilight up and calming Spike and her down, Junior and Fluttershy explained the situation to them.
"Wait, but how is this possible? Edmontosauruses and other dinosaurs went extinct 65 million years ago! How are you here, talking to us?!" Twilight exclaimed.
"Well, my mom told me a long time ago that when this supposed "extinction" happened, some of the surviving dinosaurs were able to find escape underground through a cave." Junior explained.
"Fascinating." Twilight replied.
"That's kind of the reason I took Junior with me to see you, Twilight." Fluttershy said. "We need your help."
"What do you need help with it?" Twilight asked.
"Remember that earthquake a few days ago?" Fluttershy asked.
"Yes."
"And how the dinosaurs could possibly be living right under our hooves?" Fluttershy asked.
"Yeah, Junior just said that."
"Well, that earthquake caused some huge sinkholes to open up in the ground which is how Junior's here. Unfortunately though, Junior got separated from his mother in process." Fluttershy said. "Can you come with us to help find Junior's mother? If that's okay?"
Twilight thought for a moment, worrying both Fluttershy and Junior. Finally, Twilight replied.
"Alright, Fluttershy. We'll help Junior get back to his mom, I promise." Twilight said.
Fluttershy grinned and Junior went to hug to Twilight. Although she was caught off guard, Twilight hugged the little Edmontosaurus back. "Although, we are gonna need some help."
"Wait, from who?" Junior asked.
"From the other Elements of Harmony, of course."
After gathering all of their friends and explaining the situation to them, the Mane 6 all set out for the large hole that led Junior to Ponyville. It took a while but eventually, they found it.
"Here it is." Junior said, pointing a huge, dark cavern that led to the underground world. "I do have to warn you, ladies. There might be some really dangerous stuff down there so be careful."
"Don't worry, kid. We're the ponies that took down Tirek!" Rainbow Dash bragged, strutting a heroic pose.
"Oh, boy, here we go. We're going into unknown territory, Rainbow, we don't know what could be down there." Applejack said. Rainbow rolled her eyes and sighed.
"Relax, AJ! It's just a couple of bipedal lizards, what's the worse that can happen?" Rainbow Dash retorted.
"Applejack's right, Rainbow Dash." Twilight said. "I've read some books about dinosaurs and they are not some dumb animals."
"Whatever you say, egghead." Rainbow Dash said, rolling her eyes. "Let's get this over with!"
"Okay, girls. We're about to head where nopony has gone before." Twilight said. "Let's approach this in a calm, smart-"
"Geromino!"
The whole group turned just in time to see Rainbow Dash jumping into the abyss.
"Wait, Rainbow!" Twilight exclaimed.
"Wahoo!" Pinkie Pie exclaimed, following after Rainbow Dash.
"Well, you heard the mares, yeehaw!" Applejack exclaimed, diving into the hole.
"I really hope this doesn't mess up my mane." Rarity said, nervously before jumping in.
"Let's get you back to your mom, Junior." Fluttershy said. Junior nodded excitedly to this. They both jumped into the hole leaving Twilight by herself.
"Why do I even bother?" Twilight sighed. She carefully dived into the hole to follow her friends.
The 6 mares, plus Junior, kept on falling deeper and deeper. Fluttershy and Rarity screamed in terror while Pinkie just laughed the whole way. Eventually though, they started to see the ground slowly approaching them.
Spotting this, Twilight used her magic to pull all her friends together and form a magic forcefield to protect them from the impact. The ball landed onto the ground with a thud, leaving a huge crater. Luckily, no one was hurt.
"Woohoo! Again, again!" Pinkie exclaimed.
"No, never again!" Rarity exclaimed.
"Whoa nelly, that was a heavy fal-WHOA!" Applejack began to say before being taken aback by the beauty that surrounded the ponies.
All the ponies stared in awe at the environment that surrounded them. A large, glistening, lake stretched a great distance. A few trees and ferns decorated the otherwise sandy and earthy ground. A gushing waterfall poured gallons of water from atop a rocky cliff.
Fluttershy was especially astonished at not only the flora but also the fauna that called the lake their home. Large sauropods called Brachiosaurus took in huge gulps of water as they lowered their heads for a drink.
Gathered alongside them were some Gallimimuses and Camptosauruses. Because of their large size, the sauropods offered these small herbivores protection from hungry predators.
As the ponies continued to take in the beauty, Junior heard something in nearby forest. It was tough to see but he could make out two yellow eyes staring directly at the group. Junior tried to alert the ponies but they were too distracted.
"Uh, ladies? I think we have a problem." Junior whispered to the Mane 6. They were about to ask what the it was but their questions were soon answered. From the treeline, a two-horned carnivorous dinosaur stomped out, its sharp, pointy teeth laid bare. This was a Carnotaurus.
