As the Cakes and their guests walked in, There was a flash of pink suddenly and two six year old foals appeared. One was Spark and the other was Fable, they were laughing like crazy. "That was the best hide and go seek game ever! Though don't ever sneak up on me like that again!" Fable cried. The foals laughed but slowly looked up at who they bumped into. "Sorry…" Fable whispered. The Cakes bowed to their little princess and Spark did a mocking bow of his own. The filly giggled. "Fable? Oh, there you are." Princess Twilight laughed. "Oh, look, it's princess prissy pants." Skyla muttered. Berry glared at her. He grabbed her brown braid and pulled her into a bow. "Hello, Mr. and Mrs. Cake, Pound, Pumpkin." Twilight said, wrapping her arms around Fable. "Hey Fable, Spark, how are you?" Pumpkin asked. "You know them?" Berry asked. "Yep! Of course they know her! I used to live with them and I know everything about everypony!" A bubbly voice from the hallway said. "Oh Celestia help me!" Skyla whispered. Pinkie Pie came in and the twins squealed. "Auntie Pinkie!" They said together, running into a bear hug. When Pinkie saw Berry and Skyla, she gasped. "Um… Are you okay?" Berry asked. "You brought ponies here!" The element of laughter screamed. Pinkie bounced over and hugged Berry. Berry had never had a hug and he liked hugs, he realized. Skyla tried to run, but Pinkie scooped her in the hug. "Let me go!" Skyla creid. The pink pony let her go, but everypony was staring at her. "So… Um, Pound, Pumpkin, want to see something with me and Spark? Your friends can come too!" Fable said. Twilight gasped. "Honey, it could be dangerous! You foals can't go alone!" She cried. "Princess, we're twelve, we can take care of them." Pound said. "Please, I'm older than that!" Berry muttered. The ponies looked at him. "Well, I am one hundred and…..eighteen?" The changeling asked himself. The room was silent then Pinkie started laughing. "That's funny!" She cried. Berry looked confused. "Ha, ha! He was joking! He's only eighteen!" Skyla said, glaring at him. "I have my magic too." Spark said. "And I have…" Fable started. "Oh, that's right, you can only perform shields and only when the time is right." Spark said. His friend bit her lip. "Sorry…" Spark whispered. "Still, you must bring uncle Spike with you." Twilight insisted. Spike, who was a bit taller in size then when the castle was made, happened to be walking down the stairs. "Did you hear that, Spike? Can you watch the kids and make sure they are safe?" The princess asked. "Do I have to foal sit them?" Spike groaned. "Please!" Twilight pleaded. "Fine!" The dragon sighed. He looked around for his partly niece and found she and her friends had already left. Twilight blushed. "Sorry!" She whispered. Spike muttered something under his breath and walked out.
"Maybe we should have waited for uncle Spike…" Fable said. Skyla only rolled her eyes. "He would slow us down! So where are we going, princess?" The changeling asked. "It's called the castle of the two sisters!" The girl said. "But isn't that in the everfree forest?" Pound gasped. "The castle of the two sisters, huh?" Skyla whispered. Berry caught her saying it and whispered back, "Skyla, I must warn you, if you do anything to that castle, you'll be in serious danger!" He said. "Let's hurry up! I want to get to that castle!" Skyla called to the other children. Pumpkin smiled. "Skyla has the right idea! Let's go!" The mare cried. Fable turned to Skyla. "Skyla? Is that that your name, girl?" She asked. The foal nodded and Fable narrowed her eyes. Oh really? My cousin… Her name was Skyla… but I think… given to circumstances… well, she's probably… Dead…" The girl whispered. The foals looked at her in shock. "D-dead?" Skyla cried. "Something told me she was never coming back…" Fable sighed. Spark put his arm around Fable. "Well… Um, maybe we should go to the castle now?" Pound whispered. The princess nodded. They walked into the forest for a bit and found the castle. They were all amazed as they peered around, Skyla looked out the window and saw that bellow, in a big valley, there was a tree that shone like silver, there were six different colored leafs on it, but Skyla knew too well these trinkets were not leafs. "The tree of harmony…" She whispered. Fable and Spark looked over and the princess gasped. "Hey look! It's the organ of the outside!" She said."I believe that it's this key…" Fable said, pressing down the most worn key. There was a loud sound and what used to be Princess Celestia throne spun around, a pedestal replaced it and on it, propped up was a dusty old book with two alicorns on it. "That's it! This book reveals all the secrets of the castle!" The pony princess giggled. The twins rushed to it and hit heads but Spark levitated it over to his friend. Even Berry ran up ad Fable blew the dust off the cover and opened it. Skyla only rolled her eyes. A few minutes later, the children looked up to see the tree of harmony out the window. "Oh no!" Twilight's daughter cried, seeing Skyla come closer to the tree. "Spark, please-" Spark only nodded, lit his horn and the friends vanished. "Really?" Pound groaned. Berry suddenly lit his horn and vanished as well. "Come on! There's got to be a secret entrance in this book!"
Skyla was about to reach the element of magic when she heard a voice. "Stop! You're making a big mistake!" Fable yelled. She turned to face her cousin and Spark. The hidden changeling only smirked. "You're the one making a mistake, princess! You and your little boyfriend better-" Skyla was interrupted. "What are you doing?" Berry gasped, appearing beside them. The girl only rolled her eyes and grabbed the element of magic. Suddenly, the ground started to shake and the tree lost it's glow and the elements of harmony dropped from it. Skyla gasped and suddenly black thorn infested vines shot from the ground, grabbing her and pulling her down. The vines curled around the elements of harmony and had captured Spark, Berry, and Fable, and since the filly was a princess of friendship, therefore could hold all elements, the vine twisted around her neck, not killing her but about to. The princess choked for air, reaching for the elements. Spark started to levitate them to her, but even more vines grabbed his horn, making it impossible. "Somepony…. Help…" Fable cried, clawing at the vines. Suddenly, a beam hit the plant and it vanished from the girl's neck. She gasped and breathed in. The children looked up and saw the bearers of the elements standing there. The vines shot at them but princess Twilight flew up and hit them with her magic. The mares hit the vines and Spike, who was transported along, ran and grabbed the elements. Vines tackled the dragon to the ground and Rarity screamed. Twilight ran to her assistant but there was a green beam that suddenly hit the vine away, and the others. The mane six took no time to wonder who it was from, they just put the elements back to the tree. The plant shined and sent a light wave from itself, stopping the plants for good. "Is everypony okay?" Fluttershy asked. "What were you thinking?!" Rainbow cried. "What was that beam?" Applejack asked. "Can you do it again?" Pinkie squealed. "Everypony stop!" Twilight cried. They all turned and the alicorn sighed. "Fable, what happened?" The kids all looked at Skyla.
"Well, well, well! I knew she couldn't stay hidden for long!" Queen Chrysalis laughed. "It's very convenient that the elements and her little dragon friend were saved, princess Twilight should thank me for that!" Chrysalis said. "My queen, princess Skyla… Are we to go and destroy her?" A changeling asked. "No….I want her alive and well, but considering her want to leave so much, I want you to track down the girl and watch her movements." The Queen said.
