Eric Sparkle and the Storm King

Eric and his friends kept going until they noticed Twilight and her friends trying to look for the hippogriffs. They went through city gate of Hippogriffia until there were suddenly quiet strings and woodwinds from a distance, as they saw that the place was abandoned and looked creepy, including the abandoned ruins.

“This place feels kinda creepy,” Jasper said.

“Tell me about it, bro,” Smokey replied.

“Mommy! Daddy! Over here!” Eric called out to his parents.

“Eric!” Twilight replied as she and Storm hugged their son.

Rarity and Applejack shared a hug with their little sisters, Scootaloo and Rainbow did the same.

“Glad you’re here, sport,” Storm said.

“The changelings and dragons will be here soon,” Eric replied.

“Good to know,” Twilight said.

Just then, everyone heard something humming in the distance.

“I hear something!” Eric said.

“It’s coming from over there!” Twilight replied with a gasp. She then saw the Hippogriffia cathedral blocked by large rocks.

The humming kept getting louder as they carefully entered and crawled through the debris and followed the light from Twilight’s glowing horn as they walked through the rocks. After they got through the tunnel of rocks, they saw a huge red lily flower floating in the stream of inside the Hippogriffia cathedral.

“It sounds almost familiar, like something I’ve heard in a movie once,” Eric said.

As they carefully got closer, a rock accidentally crumbled from the stairs after Pinkie took a step. The humming stopped, “What was that?!” she asked.

The creature jumped into the water by diving like a dolphin.

“Hey! Wait up!” Pinkie called out, while trotting and jumping down the stairs, “Cannonball!” She then landed into the water.

“Pinkie!” Twilight said, as the Mane 7 followed her into the stream.

Eric stayed on Twilight’s back, while Nightshade and the others accompanied them into the water.

Pinkie suddenly swam over, popped out of the water, and sputtered the water out of her mouth, “She's gone!” she replied.

The water started flushing. “Now what?” Twilight asked, until there were bubbles everywhere.

“Huh?” Pinkie Pie looked.

Then the Mane 7, Eric and his friends started screaming as the whirlpool spun around and dragged them inside.

“Oh, boy. I hate epic adventures,” Rarity said. They all kept screaming and tried to talk, until they were brought underwater in another tunnel.

Twilight and Storm then gasped for air, until they each noticed a bubble around their heads. The Mane 7, along with Spike, Eric, and his friends gasped for air as bubbles were formed around their heads.

“Way to leave it to the last minute, Twilight and Storm!” Pinkie said.

“We didn't make these bubbles!” Twilight replied.

“Then who did?” Fluttershy panted.

Eric then saw something swimming towards them. As the light came closer towards them, it revealed herself as a seapony with grayish yellow scales, cyan eyes, and an arctic blue mane and tail fins.

“Hello? We're looking for the Hippogriffs,” Twilight said.

“How do I know I can trust you?” Princess Skystar asked, until she saw Eric behind Twilight and Storm but then got all excited. “OH MY GOSH!!! WHO’RE THESE LITTLE ONES?! THEY’RE SO ADORABLE!!!” The seapony then spun around with Eric and his friends in her hooves and then brought them towards her chest for a tightly gentle hug. “And I’m serious! You really are adorable I could just smother you in my arms! Oooooh!” Eric and the other kids whimpered for air as their bubbles felt like they were about to pop, so Skystar handed him back over to Twilight. “I’m glad you enjoyed hugging my son and his friends,” she said.

“He’s your son?! That’s twice as adorable!” Skystar replied.

“Please. The Storm King invaded our land, and we need their help,” Twilight said.

“The Storm King?! I'm so glad I saved you guys! I'm totally taking you to my mom! I’m sure you’ll be safe there,” Skystar replied.

Twilight gasped, “Does your mother know where they are?”

“Can you please take us?” Eric asked.

“Oho! She might have an idea!” Princess Skystar replied in singsong, then giggled.

“Hoo-hoo!” Twilight chuckled excitedly, and then they all followed Princess Skystar as she lead them ahead, after Storm put Eric on Twilight’s back so he wouldn’t drift off accidentally.

“Don’t worry, sport. Everything’s gonna be fine, okay?” Storm said.

Eric nodded, and then held onto his mother’s neck while they kept moving on.

“We're almost there!” Princess Skystar said. Once she, the Mane 7, Spike, Eric, and his friends crossed the tunnel, they saw the underwater kingdom of Seaquestria.

“Wow!” The Mane 7, Spike and Eric said, as they continued to follow Princess Skystar inside. Upon entry, the Mane 7 and Spike gazed in awe while Eric saw another female seapony, but she was queen sized with whitish fuchsia scales, magenta eyes, fuchsia and mulberry mane and tail fins.

“Mother, look what I found!” Skystar said.

“Is it another shell?” the queen asked.

Princess Skystar shook her head, “Mm-mm.”

“Because I am telling you if it is another shell, I am—“ Queen Novo then gasped loudly after seeing their guests.

“Princess Skystar, what have you done?! You know surface dwellers are forbidden here! Guards!” The guards grunted as the Mane 7, Eric, his friends, and Spike gasped.

Princess Skystar swam up to Queen Novo, “No no n-no! M-M-Mom, please! It is so not like that! They mean no harm! The Storm King is trying to destroy their home, too!” Queen Novo looked at the Mane 7 with a sternly confused look.

“We need to find the Hippogriffs. Do you know what happened to them?” Twilight asked.

“Well, of course I know. I'm the queen. I know everything,” Queen Novo replied.

“Oh, oh, it's such a great story!” Princess Skystar said.

“Don't you dare tell them!” Queen Novo scolded.

“Once upon a time, like, a while ago, the Hippogriffs did live on Mount Aris,” Princess Skystar said, as the Mane 7 were amazed.

Queen Novo grunted, “Did I not say don't tell them? But hey, I'm just the queen. Don't mind me.” She then gave a dismissed look and swam away unapproved.

“Fine! I can't tell you! But if I could tell you, I'd say that that horned beast did show up to steal their magic! But, to keep it out of his clutches, Queen Novo, hid them deep underwater where he could never go! But I can’t tell you how or why because it’s a big secret, so sorry,” Princess Skystar said, looking away, until winking at Eric, before he giggled.

Queen Novo suddenly saw him hiding behind Twilight, and then smiled warmly at him before swimming over to them.

“Hello there, little one,” she said in a motherly tone.

Eric was unsure about meeting Queen Novo.

“Eric, it’s okay, sweetheart. She’s not mean like Chrysalis,” Twilight said. Eric then came out and then smiled softly at the seapony queen.

“Eric, is it?” Queen Novo asked, until Eric nodded. “My, you sure are young. But don’t worry, honey. There’s no need to be afraid.” Eric then hugged her neck and then Queen Novo hugged him back with her hooves and then handed him back over to Twilight.

“Well, I guess the pearl is out the oyster now. I am Queen Novo,” she said.

“Good to meet you, Queen Novo. You too, Princess Skystar,” Eric replied, “These are my friends, Sweetie Belle, Nightshade, Apple Bloom, Slapstick, Scootaloo, Marina, Zuni, Holly, Pincer, Jasper, and Smokey.”

“Good to meet you all,” Queen Novo said.

“Hold on now. Lemme get this straight. When the Storm King came, you just abandoned your entire city and fled?” Applejack asked.

“We didn't flee! We swam! Y'know, in order to flee,” Princess Skystar replied.

“But... how?” Twilight asked.

Princess Skystar then got excited, “Oh! Can we show them? Huh? These are the first guests we've had in, like, foreveeerrr! Can we, can we, can we, can we, can we, can we, can we, can we, can we?”

“Well, I suppose I should make sure it still works,” Queen Novo chuckled.

She and Princess Skystar swam around a huge jellyfish that had a blue flower underneath, revealing the Pearl of Transformation.

Princess Skystar giggled excitedly as Queen Novo held the pearl in her hooves. “Careful, now,” she said.

The queen then she placed her other hoof on top of the pearl, activating its metamorphic magic towards the Mane 7, along with Spike, Eric, and his friends. This caused Princess Skystar to excitedly squeal. Pincer held his breath, then popped his air bubble and shape-shifted into a seapony.

The Mane 7 looked at the magic from the pearl showering around them, “Huh?” Suddenly, Twilight, Rarity, Fluttershy, Applejack, Rainbow Dash, Pinkie Pie, Storm, Jasper, and Smokey were starting to magically transform into seaponies. Apple Bloom, Sweetie Belle, Scootaloo, and Nightshade were also transformed into seaponies. Zuni was transformed into a sea-zebra, while Holly was transformed into a sea-deer, and Slapstick transformed into a form similar to the constellation Capricorn.

Holly and Slapstick’s aquatic forms had webbed hooves and hands, along with the tail flukes of a dolphin.

“Oh!” Twilight and Storm said while laughing in amazement as they and their friends gazed at their new body features.

“Ooh! Oh!” Fluttershy laughed while gazing at her transformation.

“Oh. Wa-wa-whoa!” Applejack laughed and loved her seapony tail, then turned to her boyfriend, “Lookin’ good, Smokey.”

“Thanks, AJ,” Smokey replied.

The Mane 7, along with Jasper, Smokey, the CMC and Nightshade gazed at their new seapony looks with awed reactions and laughs of amazement. Holly and Slapstick were also amazed by their looks.

“This is amazing!” Storm said, touching his seapony tail, then asked flirtatiously, “How do I look, honey?”

“Lookin’ good, babe,” Twilight giggled.

Fluttershy and Rainbow Dash laughed in amazement.

“These fins are divine!” Rarity said.

“Hey, Applejack, I'll race ya to that coral!” Rainbow said, swimming on ahead.

“You're on!” Applejack replied, swimming up towards Rainbow Dash.

“Woo-hoo!” Pinkie giggled, doing a double flip with her seapony body. “Ooh! Try it, Fluttershy!”

Fluttershy giggled, until she caught her tail, “Yay.”

“Guys? Guys? What is...” Spike, who was now a puffer fish, inflated like a balloon. “...happening?!”

“Aw, so cute!” Fluttershy said.

“Mommy? Daddy?” Eric asked, nervously but softly smiling at his new look. They all gasped and saw that he had small gills on his neck, webbed hands, and his legs resembled the rear flippers of a seal. “Is this normal?”

“I believe so. You’re like a seapony but with human and seal-like features,” Twilight replied.

“You’re now a merman,” Jasper said.

“Only with no fishy tail,” Smokey added.

“This is amazing! With this, we could transform everypony at home into something powerful enough to face the Storm King's army!“ Twilight said.

“I don’t think that’s how it works. The pearl can only transform walking creatures into aquatic forms, correct?” Storm asked.

“Yes, it’s so precious to us that we don’t want it to end up in his greedy claws,” Queen Novo replied.

“But…” Twilight tried to say.

“Honey, I'm sorry about your home. I truly am. But my responsibility is to protect my subjects. The pearl... is not going anywhere,” Queen Novo replied.

“But we've come all this way. And you can't just hide down here! Trapped forever! There's so much you're missing!” Twilight said.

“We are one hundred percent okay with that!” Queen Novo replied.

“As Princess Celestia said, we have all the magic we’ll need,” Storm said to Twilight reassuringly.

“Even without the pearl, there must be something you can do to help,” Eric said to the queen.

“I’ll have to think on that, Eric,” Queen Novo replied, until she heard Jamal chattering next to her holding some seaweed. “Oh! Now if you’ll excuse me, it’s time for my seaweed wrap. Mama needs her massage too as well.” She then swam away.

“So that's it? We left home for nothin'?” Applejack asked.

“Not quite. Queen Novo said she’ll have to think of another way to help us without the pearl,” Eric replied.

“Oh, my gosh! Best... idea! You can stay with us! Forever!” Princess Skystar said, laughing, “There are so many things we can do! We can make friendship bracelets out of shells and... picture frames outta shells and... decorative wastebaskets out of shells... Oh, I have so many projects that involve shells, haha! Now I have someone new to share them with! I mean, aside from my friends, Shelly and Sheldon. Right? "Shelly"? And "Sheldon"?” She then nervously chuckled, “Get it?” She chuckled, and then snorted.

“That sounds lovely, darling, but you must realize, we can't stay,” Rarity said.

“We've gotta get back to our families and special someponies,” Applejack added.

“I know we have to go, but you guys saw how nice and friendly Princess Skystar was. Couldn't we stay for just a little longer?” Pinkie asked, until Applejack replied, “Pinkie, we just don't have time for—“ Twilight then cut her off, “No. I think Pinkie's right.”

Rainbow Dash and the other 6 were confused, “Say what now?”

“Well, we still need to come up with a plan to get back. A few minutes or probably an hour or two... or three won't make a huge difference. And if there's anypony who can cram a lifetime of fun into a blink of an eye, it's Pinkie Pie!” Pinkie made a beaming smile with a squee. “So, let’s go ahead and show Skystar the best time ever!” Twilight said until Pinkie saluted her. “We won't let you down!”

“We’re counting on it,” Twilight said, with Storm and Eric nodding in agreement.

She and the rest of the Mane 7, along with Eric and his friends were giggling while swimming over to Princess Skystar. Princess Skystar was playing a sad harp, “It's probably for the best.” She kept holding back her tears until she saw Pinkie Pie imitating Shelly and Sheldon.

Pinkie’s singing quickly convinced the young princess, and so she happily led Twilight, Storm, and the others out into the middle of Seaquestria to swim playfully. She quickly started doing more activities, all while singing happily. Both Pinkie and Skystar were having the time of their lives. Their joy quickly spread to the others, luring them in. Meanwhile, the two new friends started to sing in unison.

It soon became a chorus. This drew in many of the residents of Seaquestria, who could not recall the last time they'd had so much fun and joy in their lives. Their harmonious, joyful singing echoed through the depths. In the span of just a few minutes, they had brightened up everyone's spirits. The princess was then joined by the residents of Seaquestria, including her mom, as they all sang together.

“Woo!” Queen Novo laughed.

“Hmm?” Princess Skystar asked as she saw her mother feeling like she enjoyed the celebration. Pinkie giggled, and then the rest of the Mane 7, Eric, and his friends laughed.

“Well, I guess there is one small thing we can do,” Queen Novo said.

The others nodded in agreement, and then they went back with Queen Novo and swam back to her throne room.

“Thank you, Queen Novo,” Eric said.

“Don’t mention it. We’ll join you soon,” Queen Novo replied, using the pearl to return them to the surface.
