Fluttershy and Rarity are going through the gems they've collected for outfits. "Wow, Rarity. You sure got a lot of emeralds in here." said Fluttershy. "I know, right. I should make something spring like." said Rarity. "There's also some rubies, topazes, aquamarines, and a dinosaur bone." said Fluttershy as she pulls out a small dinosaur bone. "Oh my word! How did that get in there?!" Rarity asked in fright. "I don't know, but it's rather unique." said Fluttershy.

Suddenly, they both hear the Book of Disney calling for them. "Speaking of rather unique, we should get going. The Book of Disney is calling." said Rarity. "It is. Oh my goodness, I guess it's time for us to meet new friends." said Fluttershy as she and Rarity ran towards Twilight's castle. When they got there, Twilight opened the next chapter to the book. The next story is Dinosaur. She began to read,

"Millions of years ago, there were creatures known as dinosaurs. They come to life when they were hatched from an egg, and one of them survived an attack caused by the vicious Carnotaur. The little egg traveled far away until it landed on a tree filled with lemurs. Once the egg hatched, it was revealed to be a baby Iguanodon. The leader of the lemurs Yar wants to get rid of it because he thought the baby would become a meat eater, but his daughter Plio suggested to keep him. Which he agrees. The baby was named Aladar and grew up to be a gentle giant. One night, a giant meteor crashes into the earth and destroyed everything. Well, almost everything. Aladar still has his family by his side and will find a better home for him and his family."

Once she's done reading, she and her friends got sucked in by the book.

...

They ended up in a place that was like a desert.

"What is this place? It's very dusty here." Rarity asked. "I don't know, but it doesn't look like a safe place." Applejack replied. "You're right, AJ. I'd say we keep going until meet someone who doesn't eat us." said Twilight. "But, what if that someone is mean?" Fluttershy asked. "Leave that to me, Fluttershy. I'll tell you when a smile is right or wrong." said Pinkie.

And then, a big dinosaur appeared right in front of them with four lemurs on his back. "Excuse me?! Are you guys lost?!" he shouted out to the girls. "Um, actually. We are. We don't know what this place is. I'm sure you don't either." said Twilight. "You're right, I don't. And, I've never seen creatures like you before. Who are you?" the dinosaur asked. "I'm Twilight Sparkle and these are my friends. Fluttershy, Rarity, Applejack, Pinkie Pie, and Rainbow Dash." Twilight introduced. "My names Aladar. This is my family, and this is all we have." he introduced. "Oh my. I'm so sorry. Is there anything we can do?" Fluttershy asked. "Well, meeting you guys is nice." Aladar replied. "We're planning on moving forward to see if there are other life forms nearby." said Twilight. "Oh, I like that idea." said Aladar.

Suddenly, they heard some slick moves coming from a smaller dinosaur. "Whoa, did you see that?" Rainbow Dash asked. "See what? I don't see anything." Rarity asked. "I thought I saw something that went really fast." Rainbow Dash replied. The dinosaur she saw was actually called a velociraptor it was not alone, there were dozens of them. The mane six and Aladar screamed as they ran for their lives. "What are these things?!" Fluttershy asked. "I don't know, but they don't look friendly!" Applejack shouted.

As they keep running from the raptors, they accidentally bumped into a cold hearted dinosaur who looks just like Aladar named Kron. "Stay out of my way!" he shouted. And then, they saw a whole herd of dinosaurs right behind him. "Oh my Celestia." Twilight muttered. "At least we escaped from whatever those things are." said Rainbow Dash as she sees the raptors giving up on chasing them.

When everyone stopped walking and began resting, Kron and his sister Neera went to the mane six and Aladar to confront them. "You! What do you think you were doing here?!" he shouted. "We're sorry, my family and friends just got here and we need rest." Aladar explained. "You don't deserve to be here!" said Kron. "Hey, what is the matter with you?! Can't you be a little nicer than that?!" Twilight shouted. "How dare you judge me the way I lead! Oh, so help me!" Kron shouted.

"Kron, please. Be gentle." said his younger sister Neera. "Fine, they'll stay. But, heed my warning. Don't get in my way." said Kron as he leaves with his companion Bruton. "Thank you, miss. I don't know what is wrong with him." said Aladar. "He's always like that. And please, call me Neera." she introduced. "I'm Aladar." he introduced. "You're welcome to stay in the herd of you like." said Neera. "We'd be honored. But, we still don't like that guy who was rude to us." said Aladar. "I know. Sometimes, I wish he wasn't my brother." said Neera. "Wait, he's your brother?! But, why is he so brutal?" Pinkie asked. "It's ok. You better get some rest for tomorrow. It's going to be a long trip." said Neera. "Thank you, Neera." said Aladar. "Don't mention it." said Neera.

So after that, everyone got rested up and went to sleep.

...

The next morning, everyone woke up in a bad mood thanks to Kron's brutal ways of learning.

"Oh, does he always act like this in the morning?" Rainbow Dash complained as she tries to go back to sleep. "Well, we have to get going so that we can help these dinosaurs find better civilization." said Twilight. "Ok, I'm up. Let's get going." said Rainbow Dash as she got up.

"Looks like somebody doesn't like the rules." said an elderly dinosaur named Eema. "You don't like them either?" Rainbow Dash asked. "Not really, but we still have to follow them in order to survive." Eema replied. "Yeah, I know. That's what we're doing." said Aladar. "So, who are you?" Twilight asked. "My names Eema and this is my good old friend Baylene." Eema introduced. "Nice to meet y'all. We better get going otherwise Kron will whoop our butts off." said Applejack.

So after hours of walking, they tried to find a place with water. "So, where are we going?" Rarity asked. "I heard we're trying to find water." Aladar replied. "Oh, thank goodness. I'm getting thirsty over here." said Rarity. "Just a little further." said Rainbow Dash. "How close are we?" Twilight asked. "I think Kron found something!" Rainbow Dash shouted. "Did they find some water?" Applejack asked.

Rainbow Dash flew towards Kron and Neera when they stopped and saw completely nothing. "Wait, where's the water?" she asked. "It's not here. Why isn't it here?" Kron asked in gruff. "I don't know, it looks dried up." Neera replied. "Dried up?! It can't be dried up! My friends are thirsty!" Rainbow Dash shouted. "Well, why don't you tell them yourself?!" Kron shouted as he whacks her with his tail as she flies back to her friends. Rainbow Dash landed on the ground hard.

"Well, what did they say?" Aladar asked. "The water's dried up. There's nothing but dust." Rainbow Dash replied. "Oh no. That's not supposed to happen, they need the water. Otherwise they'll die of dehydration." said Rarity. "Rarity's right. We still need to find water. It may be dried up, but there's still water underneath. I can feel it in the ground." said Twilight. "I can feel it too. But, how do we bring it to the surface?" Pinkie asked. "Well, we better hurry up because Eema needs it like now." said Applejack as she tries to help a collapsing Eema.

Twilight has gotten herself an idea. "Baylene, place your foot on the ground and press it really hard. Applejack and Pinkie Pie, keep digging until you see water rising up." she ordered. "Aye aye, Twilight." said Pinkie as she and Applejack start digging while Baylene presses her foot to the ground hard. And suddenly, there was water. "Water. We found water!" Applejack shouted. "We did it! We did it!" Pinkie shouted. "Come over here, Eema. You need to drink." said Rarity as she brought Eema to the water and she begins to drink.

And then, a lot of the dinosaurs came to them since they announced they have water. "Wait, it's not enough for everyone!" Twilight shouted. But, they didn't listen. Kron noticed this and forced everyone not to drink the water.

He was fighting with them for so long that it lasted all day.

...

When it was sunset, the mane six have completed the lake by turning it into water again by making it fresh and clear.

"Good job, girls. Now, the entire herd can have some water." said Aladar. "Good thing Kron didn't bother us while we were working." said Applejack. "Well, he was on patrol. In case there are carnivores nearby." said Aladar. "What's a carnivore?" Fluttershy asked. "A carnivore is an animal that eats other animals like me." Aladar replied. Fluttershy gulped in nervousness, and said, "We never get carnivores in Equestria." "Good thing too." said Pinkie.

"Mind if I come in?" Neera asked. "Oh hi, Neera. Are you thirsty?" Aladar asked. "Actually, I am. It looks so pure and clean." said Neera. "Yep, we made it ourselves. With a hint of magic." said Twilight. "Thank you. All of you. I'm so glad that you didn't leave." said Neera. "We would never leave when it comes to situations like this. It's our job." said Twilight. "Well, I'm glad you're helping us survive." said Neera. "Well, let's drink up then." said Applejack. So, everyone began drinking the clean water and enjoys it.

But, the moment didn't last long when they hear roaring. "What was that?" Pinkie asked. "It sounds like a warning." Aladar replied. "And it doesn't sound good at all. I can tell by the tone." said Fluttershy. They went to Kron to ask him what's going on. "Kron, what's going on?" Neera asked. "Carnotaurs, they're coming right to us. We have to move the herd double time." Kron replied. "Carnotaurs?" Twilight asked. "They're vicious predators that kill and eat us. So, let's move it!" Kron shouted.

"But, what about the elders? We need to help them." Applejack asked. "They'll slow the predators down." Kron replied coldly. "You can't sacrifice them for this!" Aladar shouted. Kron roared at him as he pinned him down. "If you interfere with me again, I'll kill you." he said as he takes Neera with him. "Neera!" Twilight shouted. "It's ok, girls. I'll be okay." said Neera as she goes with her brother. "We better get the elders so we can help them." said Applejack.

When they got to the elders, the was gone just like that. "Hey, where did the herd go?" Pinkie asked.

...

When it got dark out, the mane six, Aladar, and the elders were very anxious about finding the herd or avoiding the Carnataurs.

"Oh man, I can't we lost the herd. It feels like Kron wants to get rid of us." said Rainbow Dash. "That's what I was thinking. We did so much for the herd and this is what we get in return." said Rarity. "And now, we're being hunted down by Carnotaurs. How many are there?" Fluttershy asked in worrisome. "I heard there's two of them." Eema replied. "Two Carnataurs?!" Fluttershy asked in fear. "Oh, that's bad news. We need to find somewhere safe and fast!" Pinkie shouted. "Keep it down, Pinkie. They'll hear you." said Rainbow Dash.

While looking for a safe place to spend the night in, they saw Bruton mortally wounded and could not catch up to the herd. "Oh, its Bruton." said Eema. "We should help him. He looks hurt." said Fluttershy. "Well come on, then. Let's help him." said Applejack as she and the others went towards Bruton. "What happened to him?" Twilight asked. "It looks like a Carnotaur attacked him. He's lucky to be alive." said Fluttershy. "Save your pity. I'm just getting some rest. Now, get away from me!" Bruton shouted. "Suit yourself then." said Aladar.

Pinkie managed to find a nearby cave that's big enough for the group. Aladar noticed it too and said, "Change your mind, there's a cave for you to sleep in." Once everyone is in the cave, everyone sat down in exhaustion while Rarity began to heal Bruton. "What are you doing?" Bruton asked. "Healing you, of course." Rarity replied as she finishes healing him. "Thanks for finding this place, Pinkie." said Aladar. "No problem." said Pinkie.

And then, it starts to rain. But, they didn't mind that at all. "Good thing we didn't get caught in this rain, otherwise it'll be dreadful." said Rarity. "The entire trip is dreadful! We have a bad leader that hates us including Aladar, been abondoned by that same leader, and now we're stuck here!" Rainbow Dash shouted. "Look on the bright side, at least we don't see any Carnotaurs. For now." said Applejack. "Let's just keep an eye on them, in case they walk by." said Twilight. "Don't worry, girls. We'll get there in no time." Aladar promised. "Yeah, and we'll teach Kron a piece of my mind for leaving us. Including Bruton." said Rainbow Dash. "At least he's one of us now." said Fluttershy. "Let's get some rest. We have a long day ahead of us tomorrow." said Twilight.

Everyone began to rest up and fell asleep almost immediately.

Once everyone was asleep, Aladar began hearing stomping noises coming from outside. It was the Carnotaurs, and there were two of them.

The mane six saw them as well and were frightened by their appearances. They tried their best not to scream, otherwise it'll catch the attention of the predators. "What do we do?" Twilight asked. "Wake the others. There's a passage way over there." said Aladar as he suggested the girls to go to the passage way along with the lemurs and the elders. "What about the Carnotaurs?" Twilight asked. "They're getting closer." said Fluttershy. "Don't let them see you. Your bright colors will catch their attention." said Aladar.

Everyone else got inside the passage way and are waiting for Aladar to come to them. But, a rock was accidentally knocked over and tumbled towards the Carnotaurs. They noticed that there's food in that cave and they went in without warning. Once they saw Aladar, they began to attack him as he ran for his life. "ALADAR!" Twilight shouted. Aladar was catching up to them, but the Carnotaurs caught his tail and was about to kill him. And then, Bruton knocked them down and shouted, "Go, I'll hold them off. Help the others!" Aladar ran for his life and caught up with the mane six.

What Bruton did was the unthinkable. He uses his strength to cause a rock avalanche to kill the Carnotaurs, but it costed his life to do so. "No! Bruton!" Aladar shouted. Once the rock avalanche was over with, he digged up to fin Bruton only to find him dead. "Oh no. He didn't make it." said Fluttershy. "But, he died like a good solider would." said Applejack as she takes off her hat to honor Bruton.

After mourning Bruton, they had no choice but to move on. Suddenly, they saw a Carnotaur who survived the rocks and roars at them for revenge. Then, it leaves.

...

When everyone kept on going further to the cave, they ended up on a rocky trail which they think is a dead end.

"Oh no, it's a dead end." said Rainbow Dash. "Maybe there's something on the other side." said Twilight. "Are you sure about that?" Rarity asked. "I'm positive. I think I see a light up there." Twilight replied. Fluttershy flew up and saw the light. "I see it too. We could knock all of these rocks down." she said. "She's right, we're gonna push them until we see a bright sunny day!" Applejack shouted as she starts kicking the rocks. Everyone else began to do the same thing.

"Keep going!" Aladar shouted. But suddenly, the light disappeared. "No!" Rainbow Dash shouted. "Now what? We're stuck here!" Aladar shouted. "Oh no, we're not. We are not staying here to die and rot. We are getting out of this place, whether you like it or not!" Twilight shouted as she uses her magic with all of her might to blast the rocks out of the way.

And then, they saw a beautiful nesting ground and a perfect civilization. "Whoa, I can't believe it. We're here." said Aladar. "The nesting grounds. It's untouched." Eema gasped. "And it looks like we're the first ones here." said Applejack. "And we got ourselves a pool!" Pinkie shouted as she jumps into the lake and swims like a little fish. Baylene jumped in with her and caused a wave to make it more fun.

While everyone was having fun with the nesting grounds, Aladar realizes that the herd is on the other side of a large cliff. "What's wrong, Aladar?" Twilight asked. "The herd's on the other side of that cliff. They're never going to make it since it's really deep. We have to get them, no matter what Kron says." Aladar replied to her. "Are you crazy? Kron is going to kill you!" Twilight warned. "I'd rather see him try." said Aladar as he ran back to the cave while the mane six follows him.

When they got back to the cave, they saw the Carnotaur they encountered last night and was eating a dead dinosaur. They sneaked past it and went straight towards the herd.

...

When they saw the herd being forced to climb the rocks by Kron, they immediately went towards him to warn everyone.

"Kron! We have to get the herd out of here now! A Carnotaur is coming!" Aladar shouted. "There's a safer side to the nesting grounds, and we've been there!" Twilight shouted. "Keep moving!" Kron shouted, meaning he doesn't listen to them. "Kron, listen to him." said Neera. "No, don't go to that side. There's a deep drop that could kill everyone." said Aladar. Kron still doesn't listen and keeps going. "You're going to kill the herd! There's still a better way!" Applejack shouted. "Follow me, I'll show you!" said Aladar.

Kron had enough of Aladar and decided to finish him off by force. He began to attack by knocking him down and scratched him on the chest. "Aladar!" the mane six shouted. When Kron was ready to release his final strike, Neera knocked down her down her own brother and helped Aladar. She agreed on his decision and let's the herd follow Aladar's lead. "NEERA!" Kron shouted. But, she didn't listen to him. In fact, she doesn't want to listen to her brother anymore and will stick to Aladar from now on.

Once everyone was about to leave, they heard a loud and vicious roar. It was the Carnotaur and it was racing towards the herd. Everyone began to panic, but Aladar calmed them down by encouraging them to stand up against it. "No, don't cower! That's what it wants you to do! Stand together!" he said. He went up straight towards the Carnotaur and roars at it, telling it to go away. Neera followed him by roaring at it as well. Then, the rest of the herd began roaring as the Carnotaur begins to back away.

When everyone leaves, the Carnotaur begins to go after Kron who is still climbing up the rocks. Neera saw this and chased after it so her brother won't get killed. "Neera, wait for us!" Twilight shouted as she and her friends followed her along with Aladar. They kept running to it, even though it's still after Kron. "Kron!" Neera shouted. "Look out! There's a Carnotaur right behind you!" Rainbow Dash shouted.

Kron ran for his life until he sees a dead end. "No." he muttered. The Carnotaur catches up to him as it bites him and throws him to the ground. When it was about to strike again, Twilight uses her magic to blast the horrible creature off the cliff. She did it so powerful and with the help of Aladar, the Carnotaur falls off the cliff and immediately dies from the fall. "We did it! We beat the Carnotaur!" Twilight shouted. "Thanks to you, Twilight. How'd you do that anyway?" Aladar asked. "It's called magic." Twilight replied.

Before they can celebrate more, they saw Neera mourning for her brother as he died from his wounds. "Kron." she muttered. "He didn't make it." Applejack muttered. "I know he was a jerk to us, but he doesn't deserve this." said Rainbow Dash. "Well, its too late now." said Twilight.

Neera nuzzled with Aladar in comfort.

...

When everyone made it to the nesting grounds, the herd was so happy that they are now free from survival and now can live happily.

"Girls, I can't thank you enough for helping me find a better life source and making me a better leader." said Aladar. "You're welcome, Aladar. Now, it's time for us to leave. We have other journeys to attend." said Twilight. "Oh, really? Alright, I won't forget you." said Aladar. "You're the best leader a dinosaur could ever ask for." said Fluttershy. "Thanks." said Aladar.

"Bye Aladar!" the mane six shouted as they disappeared. "Bye, girls!" Aladar shouted.

...

When they got back to Equestria, the mane six were really dusty from the traveling they've been doing.

"Oh my, I'm as dusty as an old house." said Rarity. "You should see me. I get dusty everyday!" said Applejack. "Come on, girls. Let's take a nice bath and clean ourselves up." said Twilight.
