Two weeks later, Randall, the cake twins and the CMC all went to the underground paradise to meet Bony Armor, Tough Femur and Frank, because they wanted to see them again, but when they all reached their house, only Tough Femur opened the door for them, and he allowed them to go inside and then he gave them some food to eat.

When Randall asked him where's Bony Armor, Tough Femur explained that she's lying down in her bed, but he also added that she's still expecting to meet all of them, because she have a surprise for all of them she wants them all to know about, and Randall and his friends all wondered what kind of surprised Bony Armor wants to tell them about, and they all went upstairs to her bedroom to meet her.

When Randall and his friends entered Bony Armor's bedroom, they saw her lying down in her bed, but she smiled to them when she saw all of them, because she still expected them to come, and she also planned to tell them about the surprise she have for every creature, which only Tough Femur and Frank already know about.

Then, when Randall accidentally touched Bony Armor's stomach, he felt that her stomach is much bigger than when the fight against Immortal Hoof and his mutated animals occurred, and Bony Armor finally revealed to the young ponies the surprise she wanted to tell everypony and every creature - Bony Armor is pregnant.

When Randall and his friends learned from Bony Armor that she's pregnant, they were all in shock, but they're also vey excited to meet the newborn when Bony Armor will give birth to it.

Then, Randall and his friends thanked Bony Armor for revealing to them she's going to have a new foal, and then, they said goodbye to her and they left her bedroom, and when they're about to leave, they also said goodbye to Tough Femur, and to Frank the gigantic black bear, who waited for them outside, and then, they all left the underground paradise, and they went back to Equestria's surface.

Then, everypony went back to Ponyville, where they all parted ways and they went to their own respective homes. When nighttime came, Randall wondered what the newborn would be, a filly or a foal, before he went to his bedroom and fell asleep.

The months have passed one by one, and Bony Armor is coming close to giving birth to her newborn within a matter of few days, and Tough Femur and Frank were both getting so excited to finally meet the newborn.

Eventually, when Bony Armor finally gave birth to her newborn, she asked Frank to go to Ponyville to search for Randall and for his friends and to take them all to their house to finally see the newborn.

When Frank found Randall and his friends, whom are now with Gabby, Blueberry, Bianca, Babs Seed, the baby six, the student six and Flurry Heart, he allowed them to have a ride on his back to the underground to meet Bony Armor and Tough Femur's newborn.

When every creature accepted, they all climbed and/or flew up onto Frank's back, and then he took off at full speed towards the underground paradise. Once they all reached there, Frank took every creature to Bony Armor and Tough Femur's house, so they can go inside to see their newborn.

When they all finally arrived in front of Bony Armor and Tough Femur's house, every creature climbed and/or flew down from Frank's back, and then, they all went and entered the Unicorns' house, to finally meet their newborn.

Once every creature went upstairs and then entered Bony Armor's bedroom, they all saw Tough Femur smiling lovingly and Bony Armor still lying in her bed, but when every creature came closer, they saw a cute newborn Unicorn filly sleeping in Bony Armor's hooves, and Randall and his friends knew exactly what was that meant to be - Bony Armor and Tough Femur have became parents once again.

When Randall saw the newborn Unicorn filly in Bony Armor's hooves, he said "Oh, she's so beautiful!", and Bianca added "And she's cute too!", and Blueberry added "I never saw a newborn pony before! She's the very first newborn pony I've ever seen in my whole life!", but then, the newborn Unicorn filly suddenly opened her eyes and she started to cry, but Bony Armor tried to calm down her newborn daughter so she won't be feeling afraid of Randall and of his friends.

Then, Tough Femur asked Randall and the others "Do you like our newborn daughter?", and Randall answered "Yes! I truly like her! I wish one day she'll even become a friend of mine!".

Then, once the newborn filly finally stopped crying, she closed her eyes and then she gave a cute and warm smile on her face, which made every creature happy, especially Randall.

However, they all suddenly heard a angry growl coming from outside, but this one doesn't comes from a dinosaur at all. When every creature looked out of the window, they saw an adult male rhinoceros standing as almost as big as Elasmotherium, and like him, he had wool covering his body, and like a large modern-day rhinoceros, that one had two horns on his snout. That prehistoric mammal was the long-lost member of the prehistoric mammals of evilness; Woolly rhinoceros.

However, when every creature looked to Woolly rhinoceros' sides, they all saw five cynodonts that were actually the same ones from which two were already dead (due to Randall and Indoraptor, who both already killed the two other cynodonts), showing every creature that Woolly rhinoceros was indeed their boss and master.

Then, Woolly rhinoceros suddenly spoke up and said to his cynodonts "Get the hedgehog for me!", and they all obeyed him and one of them answered "As you wish, master Woolly rhinoceros!", and then, they all ran towards the house and they all began to attack as they tried to claw the opening door out.

Once the opening door was finally broken down, the cynodonts finally entered Bony Armor and Tough Femur's house to capture Randall. Then, the Thrinaxodon pack all began to climb upstairs and once they all entered Bony Armor's bedroom, they found every creature trying to defend Randall, Bony Armor, the newborn Unicorn filly, and themselves.

When the cynodonts saw the newborn baby filly in Bony Armor's hooves, a female Thrinaxodon said "Woolly rhinoceros will be so proud if we give him two things to kill - the hedgehog and that newborn filly!", and then she jumped up and she tried to snatch the newborn Unicorn filly, but Randall jumped up and kicked the female Thrinaxodon in the face, thus sending her back down towards her pack-mates, and also preventing her from making a meal out the newborn Unicorn filly.

However, the four other cynodonts jumped up and they all tried to get either Randall or the newborn Unicorn filly or even both of them, but the student six all prevented this from happening.

However, the female Thrinaxodon got back up on her feet, and then she jumped and attacked every creature once more, and this time, she successfully managed to snatch Randall and then she jumped off the window with him, but luckily, they both landed on the ground unharmed.

Then, Woolly rhinoceros approached him and said "So, you're finally, little hedgehog! Elasmotherium will be so proud of my usefulness!". However, when Randall heard Elasmotherium's name, he became shocked to know that Woolly rhinoceros and Elasmotherium actually knew each other, and were also best friends.

"Did you just said Elasmotherium was actually your best friend?!" Randall asked while he was still shocked to know the truth, and Woolly rhinoceros answered and introduced himself "Exactly! I'm one of the prehistoric mammals of evilness! I'm the long-lost member of the team that was separated from the rest of the prehistoric mammals of evilness long ago! My name is Woolly rhinoceros!".

Then, he said to Randall "I also know that YOU killed Elasmotherium, haven't you?!", but Randall answered "I didn't! But at least, he got what he truly deserved!". However, Woolly rhinoceros didn't listened to Randall and he angrily said to him "Do you think you can fool me with your lies?!", and then he was about to kill Randall, but he moved out of the way and Woolly rhinoceros accidentally killed the female Thrinaxodon instead, who didn't had enough time to react and move out of the way.

With four cynodonts left, Woolly rhinoceros angrily said "You'll pay for defying the prehistoric mammals of evilness, worthless hedgehog!", and then he turned to retreat and the four remaining cynodonts jumped through the window and they all landed on the ground unharmed, before they all retreated and ran away as well.

Once the threat is gone, Randall returned back to the Unicorns' house and then he climbed upstairs and entered Bony Armor's bedroom to check on every creature to see if they're all right, and much to his relief, no one is hurt.

Then, Randall went to check on the newborn Unicorn filly to see if she's alright, and much to his full relief, she's completely unharmed. Then, every creature heard some voices calling for them from outside, and when they looked from over the window, they all saw the mane six, Princess Cadance, Shining Armor, Prince Silverback, Princess Silverback, and of course, Spike the dragon, Starlight Glimmer, Indoraptor and her baby son, who all looked up at then from outside, with Frank standing right behind them, revealing that he knew about the fight with Woolly rhinoceros, so he took And brought the others to the underground paradise to help the young ones.

Just then, Randall called for Pinkie Pie and Indoraptor, before he ran downstairs and exited Bony Armor and Tough Femur's house to meet up with both sister and favorite savior. Then, he jumped onto Pinkie Pie and he hugged her and then he did the same with Indoraptor, because he was happy to see them again.

Then, every creature came downstairs from Bony Armor's bedroom, and they all carried Bony Armor and her newborn daughter with them to show the newborn to the others. Once every creature came out of the Unicorns' house, Bony Armor and Tough Femur showed to all the others their newborn daughter.

When Pinkie Pie saw the newborn Unicorn filly, she said "Oh my gosh! It's a newborn filly!" and Indoraptor added "She's the cutest filly I've ever seen in my entire life!", and then Indoraptor's baby son came forward and then he began nuzzling the newborn Unicorn filly on the face, showing he truly likes her as a friend of his.

When every creature saw how Indoraptor's baby son nuzzled Bony Armor and Tough Femur's newborn daughter, they all knew he probably liked her so much. Then, the newborn Unicorn filly opened her eyes and she slowly turned and saw Indoraptor's baby son staring at her with a smile, and then she gave her hoof to him to touch him, but she accidentally tickled him instead, causing him to run back to his own mother.

Randall said and suggested "I guess that Indoraptor's baby son really do likes your newborn daughter, and they're nearly the same age as one another! I wish for both of them to be friends when they grow up to be bigger and stronger in the future!".

Then, Prince Silverback said "I wish that one day, I'll hold her in my arms, just like my mother held me when I was a baby gorilla.", and Shining Armor said to him "I'm sure she'll like you and your kind, because all gorillas are gentle creatures, whom are truly caring for their young.".

Then, Bony Armor and Tough Femur said goodbye to every creature, and Frank took them all back to Equestria's surface, and he brought them all to Ponyville, before they all came down from him, and then he turned to go back to the underground paradise.

Then, every creature went back to their respective places, and Randall went back to Sugarcube Corner, with Pinkie Pie and the cake twins were all by his sides. When nighttime came, Randall went upstairs to his bedroom and he fell asleep, but he also hoped while asleep that one day, the newborn Unicorn filly will become a new best friend for Indoraptor's baby son.
