In Marie's bedroom, Marie and Natasha were sitting together on the bed. They had textbooks and papers out. Onda was napping on Marie's pillow, while Costa was seated on the nightstand, munching on some cookies.

"The genotype refers to an organism's genes," Marie explained, "While the phenotype refers to an organism's observable physical attributes. If the genotype is a mixture of dominant and recessive genes, the dominant gene will appear in the phenotype. In order for an organism to show a recessive gene in its phenotype, the genotype has to be all recessive. Are you getting this, Nat?"

Natasha looked sheepish. "Uh... Could you go over bonnet squares again?"

"Punnet squares," Marie corrected.

"Yeah, those," Natasha said.

"You know, you could've asked Ruth for study help," Marie said.

"I know, but I lo-" Natasha paused. "I like, uh, spending time with you. I ask Ruth for study help enough, and you're really good at biology, anyway!"

"I'm not that good," Marie said.

"Don't sell yourself so short," Natasha said. "I wouldn't have asked for your help if you weren't so good at it!"

Onda's eyes opened, and she sat up, looking around.

"Oh, no," Marie said, turning toward the fairy. "Did we wake you up, Onda? I'm sorry."

"No, it's..." Onda began.

Costa put down her cookies and looked up, too. She flew up toward the window and looked out of it, Onda joining her soon after.

"Onda, can you sense it, too?" Costa asked her sister.

Onda nodded. "Yeah."

"What's going on, you two?" Natasha asked.

Costa turned toward Marie and Natasha. "We can sense one of the Gems of Tide."


OP: "Swim! Splash! Precure!"

EPISODE 7:
"A Gem of Tide! Between Scylla and Charybdis!"


"Man, when's Talia getting here?" Natasha said, lounging lazily on the couch.

"Be patient," Marie said.

"She lives much further from your house than either of us do," Ruth pointed out. "Relax, just give her time. She'll get here."

"You're right," Natasha said as she sat up. "I didn't think about that."

A knock came from the door.

"See?" Ruth said. "That should be her now."

"It's open!" Natasha called.

The door opened, and as expected, Talia walked in. "I'm so, so sorry I'm late!" She said. "It's a long walk, and-"

"Hey, hey, it's cool," Natasha said. "You don't have to say sorry."

Talia looked relieved. "Okay."

An older woman, noticing Talia's entrance, poked her head out of the kitchen door. "Oh, hello!" She said. "Nat, who's this?"

"Oh, hey, Mom!" Natasha said. "This is Talia. She's a new friend of mine. Talia, this is my mom. Say hi!"

Talia hesitated a bit before speaking up. "Nice to meet you, Mrs. Burke."

Natasha's mother waved a hand in the air. "Oh, please, I'm not married. Call me Flora!"

"Then, nice to meet you... Flora," Talia said.

Flora smiled. "There you go," She said. "Snacks are here in the kitchen, in case any of you girls get hungry!"

"Thanks, Mom!" Natasha called, as Flora withdrew back into the kitchen.

"What did you call us over here for?" Ruth asked.

"Can't talk about it with Natasha's mom within earshot," Marie said.

"It's important, um," Natasha leaned in close to Talia and Ruth, lowering her voice to a whisper. "Pretty Cure business."

"To your room, then?" Talia asked.

"To my room!" Natasha said. "Come on, let's go."


Natasha's bedroom was far from tidy, to put it politely.

Her bed was unmade and mountains of clothes both clean and dirty littered the floor. In most spots, the actual floor wasn't even visible. Posters of olympic swimmers were hung crookedly on the walls. The only tidy part of the room was the shelf that held Natasha's many swimming trophies and awards. As Natasha closed the door, Marie unzipped her bag, letting Onda and Costa out.

"First, let's put on some tunes!" Natasha said. She walked over to a beat-up and well-used stereo, covered in a disorderly pile of music albums. She selected an album from the pile and pulled the CD out of its case, popping it into the player. When she hit play, the sounds of a banjo and acoustic guitar filled the room, and a soft, sad-sounding man's voice sang over it.

"I didn't expect you to be a fan of folk," Talia said.

"A lot of people say that." Natasha shrugged her shoulders. "What did you think I was into?"

"Heavy metal, to be honest," Talia said.

"So, this important Pretty Cure business you talked about?" Ruth asked.

"Oh! Right," Natasha said. "Don't worry, it's good news."

Talia and Ruth sat down on the bed, while Marie and Natasha sat down on the floor.

"Earlier today, I was helping Natasha study for biology," Marie began, "And that's when Onda and Costa told us they could sense one of the Gems of Tide somewhere nearby."

"That's awesome!" Talia said, clapping her hands together.

Ruth turned to the penguins. "You two can do that?"

"Me and Onda were the guardians of the Gems," Costa said. "We're connected to them, in a way."

"Pretty cool, huh?" Onda added.

"Not to mention useful," Marie said.

"If you can sense it, where is it, then?" Ruth asked.

"That's where it gets complicated," Costa said. "We can't sense its exact location. It's more like a vague pull in the direction of it. We can point you in the right direction, but we'll still have to search for it ourselves."

"Yeah, scavenger hunt!" Natasha exclaimed, pumping her fist into the air.

Marie laughed a little. "Nat, what are you doing?"

"I'm just trying to make this a little more fun," Natasha said. "Come on, come on! Which way are we going?"

"The Gem of Tide is... That way!" Onda exclaimed, pointing with her flipper.

"You're pointing towards the wall, Onda," Marie said.

"Yeah, I think that probably would work better if we went outside first," Ruth said.

"Heehee, good idea!" Onda said.


The sun was already low on the horizon, and getting lower every minute. Most people were already home for the evening, others on their way home, a few others still out and about.

"At times like this, I almost wish we lived on the west coast instead of the east coast," Talia said, blinking in the low light. "Watching the sun set over the ocean would be so beautiful. Anyway, let's get started."

Onda and Costa were tucked inside Marie's bag with the top unzipped, hidden from sight by others but still accessible. "Let's hope nobody we might run into finds it suspicious that we're talking into a bag," Marie said. "Alright, you two. Which way is the Gem of Tide?"

Onda and Costa poked their heads out of the bag only slightly, to point in the direction. "That way!" They said in unison.

"Let's go!" Natasha shouted.

The four of them broke out into a run. It wasn't long, however, before Ruth began to slow down, her stamina failing her. Marie began slowing down shortly after her. Talia lasted for much longer than both of them, but she, too, began falling behind. Natasha stopped running as she realized she was ahead of all the others.

"Come on, what's the hold up?" Natasha called.

"Come on, Nat, we're not as active as you are," Ruth said. "I spend most of my time studying. I get winded just when I walk up the stairs."

"This is good exercise for you, then!" Natasha said.

"Why don't we transform for this?" Ruth said. "We're stronger, faster, and we have more energy and stamina in Pretty Cure form. That way, we can all keep up! Plus, Onda and Costa won't have to hide."

"That's not a bad idea," Talia said.

Natasha shrugged. "Fine, we'll do this the easy way."

The four of them ducked into a nearby alleyway, away from anyone who could possibly see them.

"Let's go, everyone," Marie said.

Natasha, Talia and Ruth all nodded.

"Pretty Cure, Tidal Power!"

"The defender of the sea with an ocean of bravery... Making a splash, Cure Coral!"

"The defender of the sea with an ocean of strength... Making waves, Cure Storm!"

"The defender of the sea with an ocean of confidence... Diving in, Cure Pearl!"

"The defender of the sea with an ocean of intelligence... Swimming in, Cure Kelp!"

"With hope and power as vast as the ocean!" All four Cures spoke together, getting into their respective poses. "We are Pretty Cure Ocean Splash!"

"Nobody can even see you," Costa said. "Was the team catchphrase really necessary this time?"

"Yes," Storm said. "Yes it was."


"So... What are we supposed to be doing?" Charybdis asked, confused.

"We are observing, my dear Charybdis," Scylla answered.

"Oh," Charybdis said. "What are we observing?"

"We are keeping our eyes out for the perfect opportunity or moment in which to strike," Scylla said.

"Oh, that makes sense," Charybdis said. "You're so smart, Scylla!"

The two of them stood upon a high rooftop, looking down over Shore City.

Charybdis sighed. "I'm bored. I want to summon a Hadalis right now!"

"I know you do, but you must be patient," Scylla said. "The perfect opportunity will present itself soon enough. When it comes, you will know."

"Okay," Charybdis said. She looked out over the horizon, spotting something strange in the distance. It was the Pretty Cure, along with the penguins, jumping from rooftop to rooftop.

"Scylla, look at that!" Charybdis pointed to the distance.

"Hmm?" Scylla looked to where Charybdis was pointing. "Is that the Pretty Cure? That's unusual. Why are they transformed right now? They certainly don't seem to be fighting."

"Maybe they're looking for something," Charybdis guessed.

"It's possible, but if that's the case, then what are they looking for?" Scylla thought for a moment, before a sly smile spread across her face. "Oh, I think I have an idea."

"What?" Charybdis asked.

Scylla took Charybdis' hands in her own. "What else could they be trying to find than one of the Gems of Tide?"

"Oh, yeah!" Charybdis said. "Of course. So, if we follow them, then they should lead us right to it!"

"That's right," Scylla said. "Come, Charybdis. I believe the perfect opportunity is right in front of us."


Eyecatch 1: Marie, Natasha, Talia and Ruth are all in beachwear, chasing Onda and Costa along the beach. Marie, however, trips on a rock and falls right on her face. The others laugh and help her up as the Precure Ocean Splash logo appears in the corner.

Eyecatch 2: Standing in a line, the girls all hold oyster shells in their hands. One by one, they open them up. Marie opens hers up, nothing, Natasha, nothing, Ruth, nothing, but when Talia opens hers up, inside is a sparkling pearl. The others look at her while she proudly smiles, and the Precure Ocean Splash logo appears.


"Are we any closer to the Gem?" Coral asked.

"No," Onda said.

All four Cures let out a deep sigh.

"Where is this thing supposed to be?" Storm said.

"We've been heading in this direction for ages," Pearl said.

"This might be a bad time, but..." Costa began.

"Oh no, has something happened?" Kelp asked, worried.

"The Gem seems to have... Switched directions," Costa said.

"Switch directions? It's a rock!" Storm said, crossing her arms. "What, did it sprout wings and fly away?"

"No explanation for how it switched directions, but at least that explains why we weren't getting any closer to it," Coral said.

"We should head for it before it changes directions again," Pearl said. "Which way is it now?"

Just like earlier, Onda and Costa both pointed their flippers in the direction. "That way!" They said in unison again.

The four Cures took a running start and leaped from the rooftop they were standing on to the next. Powerful and fast, they breezed over the skyline of Shore City, streaking through the sky like shooting stars, Onda and Costa following close behind them as they leaped from building to building.

"Stop!" Onda bellowed.

The Cures skidded to a stop on the building they stood upon.

"The Gem is somewhere close by," Costa said.

"Finally," Storm said.

"Keep your eyes peeled, everyone!" Kelp said.

"I hope we find it before the sun goes down," Pearl said. "It'll be so much harder to find once it's dark out."

Coral noticed a tree nearby to the building they stood on. It wasn't an unusual sight. There were many trees along the sidewalks, lining the streets. Looking a bit closer, she noticed a bird on one of its branches, and in its beak, the bird held a round, blue gemstone.

"Uh, Storm, I think your little theory about the Gem sprouting wings and flying away may have been true," Coral said, pointing toward the bird.

"What are you..." When Storm looked to what Coral was pointing to, she immediately burst out into laughter. "Oh my god, you can't be serious!"

When Pearl and Kelp looked over, they let out small giggles, too.

"That's a Gem of Tide for sure!" Onda said.

"That bird has it!" Costa said. "Are you serious?"

"Well, there's our explanation for how it changed directions," Coral said.

"Birds are attracted to shiny stuff, aren't they?" Storm said. "This is just hilarious. A stupid bird found the Gem before we could!"

The Cures jumped down to street level, near the base of the tree, Onda and Costa following soon after.

"I'll get it," Pearl said. She jumped off the ground, up toward the branch that the bird sat on. When she tried to reach for the Gem, however, the bird took flight to another branch. "Okay, I should have expected that," She said as she landed back on the ground.

"Here, let me try," Kelp said. "I'm going to try to sneak up on it." She grabbed onto the low-lying branches and pulled herself up. Climbing up toward the branch the bird sat on, she tried to climb out toward it, but when she shifted all her weight on the branch, she heard a snap. "Uh oh." The branch crashed toward the ground, taking Kelp with it. The bird took flight again and perched on another branch.

Kelp got up and dusted herself off. "I'm alright!"

"I've got an idea," Storm said, bending over and picking a small rock up off the ground.

"Storm, don't throw a rock at the poor thing!" Coral said.

"Don't worry, I'm not that horrible of a person," Storm said. "I'm not going to throw the rock at the bird. I'm just going to throw the rock near the bird. The rock will startle the bird, and make it drop the Gem!"

"Okay, just be careful," Coral said.

"Right! Here I go!" Storm exclaimed. She drew her arm back and threw the rock with all her might. It soared through the air before colliding with the branch the bird was perched upon. The bird once again flew away and perched on another branch, but it still held fast to the Gem of Tide. "Oh, come on! Not only did this stupid bird find the Gem before we could, but we're being outsmarted by it, too! Why does it want to hang onto the Gem so bad, anyway?"

"Onda, Costa, maybe one of you could try to grab the Gem," Coral said. "Penguins are birds, right? You could probably get close enough to the bird to get the Gem without it flying away again."

"That might work!" Onda said.

"I'll do it," Costa said. "Onda, you stay here."

"Okay," Onda said.

Costa flew up toward the bird, sitting down beside it on the branch. "Hey, what's up? Crazy weather we've been having lately, right?" The bird didn't react.

"Are you making small talk with it?" Pearl called up.

"I don't know, maybe it's friendly!" Costa called back down.

"I doubt it can understand you!" Kelp called.

"Come on, Costa, just grab the Gem so we can go home!" Storm called.

"Fine, fine," Costa said. She grabbed onto the Gem and pulled, but the bird refused to let go, holding onto it with its beak tightly and pulling back. "Come on, just hand it over, you stupid birdbrain! You don't even know how important this thing is!" Costa pulled as hard as she could, but the bird pulled even harder. The Gem slipped out of Costa's flippers and she lost her balance, falling off the branch and down toward the ground.

"Costa!" Onda shouted in horror.

Coral reacted quickly, jumping out and catching the fairy penguin in her arms. "Are you okay?"

"Yeah, I'm fine," Costa said, sitting up. "It's because of you, Coral. Thanks for catching me."

"No problem," Coral said, looking up toward the bird. "It really doesn't want to let go of the Gem, does it?"

"Perhaps we can provide some assistance?" A voice behind them said.

The Cures all turned around to see the source of the voice: Scylla, with Charybdis by her side.

"After all, we would love to have that Gem just as much as you all would," Scylla said.

"Aww, not these two again," Storm said. "They're so weird."

"I'm going to take that as a compliment," Scylla said.

Charybdis chuckled darkly. "We've been following behind you all for so long, and you never even noticed! You led us right to the Gem, and now we're gonna take it from you!"

"Well, we still found it first," Coral said.

"Yeah, finders keepers!" Storm said, playfully sticking her tongue out.

"Ah, yes, finders keepers," Scylla said. "How childish. If that were the case, then the rightful owner of the Gem would be that bird there. It certainly seems intent on keeping it."

Kelp got into a fighting stance. "If you want that Gem, then you're going to have to go through us."

"We're not going down without a fight," Pearl added.

"Fighting! Now you're speaking our language," Scylla said.

"Is it now, Scylla?" Charybdis asked. "Is now the perfect opportunity you were talking about earlier?"

"Indeed it is, my dear Charybdis," Scylla answered.

"Great," Charybdis said, grinning. She waved her hand in the air, bringing out her Hadal Vial, and uncorked it. She waved her free hand over the top, extracting a few drops of the dark liquid contained inside. "What should I make my Hadalis out of?"

"How about that troublesome bird?" Scylla suggested.

"I'll do it," Charybdis said. Charybdis pointed toward the bird. "Rise from the depths, Hadalis!"

The liquid drops raced toward the bird. When they made contact, the bird grew in size to become giant, its feathers blackening and its beak sharpening, its eyes turning bright red. The bird had been transformed into a Hadalis.

"No... They can make a Hadalis out of a living creature?" Pearl choked in horror.

"That's horrible," Kelp said.

As the transformation completed, the bird Hadalis, with the Gem of Tide still in its beak, drew its head back and swallowed the stone whole.

"What?" Coral said in disbelief.

"It... It ate it," Storm said, blinking. "It just ate the Gem of Tide. What's gonna happen now?"

The bird Hadalis began to give off a strange blue glow. It spread its wings, opened its beak, and a ghastly caw rang out from its mouth.

"It seems exposure to a Gem of Tide gave our Hadalis a little power boost," Scylla said. "Fascinating. Lady Ceto will be very pleased to hear about this."

"If you want the Gem, you'll have to beat our powered-up Hadalis!" Charybdis exclaimed.

"We haven't lost to you yet, and we don't plan on letting our streak be broken," Coral said.

"That's right, Pretty Cure Ocean Splash is invincible!" Storm boasted.

"Hadalis, attack!" Charybdis demanded.

The Hadalis spread its wings and took to the sky. It swooped down quickly, and Coral and Storm stood in its shadow with their fists drawn back, prepared to punch it with full force once it came close. However, it came down much faster than they expected it. Flying close to the ground, it swept both of them off of their feet with spread wings before either of them had a chance to react.

"Ouch," Storm said.

Coral picked herself up from the ground, hurt and a bit shaken, but still capable of fighting. "Wow... I didn't think it would be this fast."

Pearl took a running start and jumped up into the air, preparing to deliver a quick kick to the face of the Hadalis, but its movements were too quick for her. The Hadalis snapped at her, grabbing onto her and trapping her between its beak.

"Somebody help!" Pearl squealed. "I'm trapped!" She struggled and struggled, but just couldn't manage to free herself.

"You let her go!" Kelp shouted. She delivered punch after punch to the Hadalis' foot, but her punches didn't seem to have any effect. Eventually, the Hadalis, seeming to grow tired of her futile attempts, reached out with its foot. Kelp tried to run away, but she wasn't fast enough, and the Hadalis grasped her between its massive talons. "Now I'm trapped! Coral! Storm! We could use a little help here!"

"Let our friends go!" Coral and Storm shouted in unison. The two of them ran at the Hadalis, leaped up at it and punched with all their strength, but even with both of them attacking at once, the Hadalis wasn't even moved.

"No," Coral said, "How can it be so strong?"

With a fierce swipe of the Hadalis' wing, Coral and Storm were knocked back, hitting the wall of a building with a loud thud. They slid to the ground in a crumpled heap.

"Coral! Storm!" Onda and Costa screamed.

With Pearl still trapped in its beak and Kelp still trapped in its talons, the Hadalis spread its wings and took off into the sky. It finally released Pearl and Kelp, throwing them hard against the same wall Coral and Storm had hit. They landed beside their fellow Cures, all of them badly hurt and lying still. The Hadalis landed back on the ground, awaiting further orders.

"Excellent," Scylla said, pleased. "Let's finish this and get back to Abyss, Charybdis."

"Okay," Charybdis said. "Hadalis, crush them."

The Hadalis lifted its foot over the Pretty Cure and tried to bring it down on top of them, but the Cures, greatly weakened, yet still alive, caught its foot in their hands, holding it up with the last of their strength.

"We can't..." Coral began.

"...Lose here." Storm continued.

"Pretty Cure..." Pearl added.

"...Is invincible." Kelp finished.

The Pretty Cure pushed back with all they could, but as they were already weakened, they were no match for the powered-up Hadalis. There was a loud cracking noise and a cloud of dust was kicked up. When the dust cleared, the Hadalis' foot was flat against the ground.

"What?" Costa said.

"The Pretty Cure... Were defeated?" Onda said, tears already beginning to form in her eyes.

Scylla and Charybdis approached the Hadalis, both of them with smiles on their faces.

"That went well," Scylla said. "We got a Gem of Tide, and we won't have to deal with the Pretty Cure any longer. I was expecting them to surrender. This was much better!"

"Lady Ceto is going to be so pleased with us!" Charybdis said with a giggle. "Hadalis! Give me that Gem."

Charybdis held up her hand as the Hadalis bent down and opened its mouth, releasing the Gem it had swallowed at the start of its battle into her hand. The blue glow around the Hadalis faded. Charybdis held the Gem up in the fading light of the setting sun and grinned.

Onda was crying freely now. Costa patted her head with her flipper, trying to calm her sister. She looked up at Scylla and Charybdis, a scowl on her face.

"You... You're horrible!" Costa spat.

"Us? Horrible?" Scylla said. "The queen you hail has the blood of countless innocent civilians on her hands. How can you say that Abyss is any worse?"

Costa didn't say anything in response, but continued scowling at the Abyssal generals.

"We're done here, my dear Charybdis," Scylla said. "Let us be off."

"Okay," Charybdis said.

The two of them formed a dark bubble around themselves, and when the bubble popped, they were gone.

Costa continued trying to comfort Onda.

"Onda, please, stop crying," Costa said. "Everything is going to be okay."

"But it's not!" Onda shouted back. "Everything isn't going to be okay, because the Pretty Cure were the last hope for the Kingdom of Waves, and now they're... Now they're..."

Onda and Costa suddenly heard movement, and looked up to see the Hadalis' foot, the one it had used to crush the Pretty Cure, was being pushed up, by none other than the Pretty Cure.

"What? But I thought..." Costa said.

"They're... Okay?" Onda said.

Looking closely, Onda and Costa could see what had happened. The Hadalis hadn't actually crushed the Pretty Cure beneath its foot. It had instead created a crater in the ground beneath them, pushing them down into it, and blocked it off with its foot, making it appear as if they had been crushed.

The Pretty Cure pushed the Hadalis back with great strength, knocking it off its feet. They climbed up out of the crater.

Coral looked toward the penguins, and smiled. "Sorry if we made you worry."

"We're just happy to see you're okay!" Onda said.

Costa looked toward the Hadalis. "I think I understand. Holding the Gem of Tide within it made it stronger, but now that the Gem of Tide is removed, its back to normal strength."

"Today's been a long day," Storm said. "I just want to end this and go home." She approached where the Hadalis lied on the ground. "Pretty Cure, Storm Strike!"

A bolt of lightning flew out from Storm's hands toward the Hadalis, purifying it and turning it back into an ordinary bird. The bird, despite everything, seemed to be no worse for wear, spreading its wings and flying away. A bright light shone, and when it faded, all damage that had occurred during the battle was repaired, and the Pretty Cure were all completely healed.

The Cures all formed bubbles around themselves, and when they popped, they were back in their normal civilian forms.

"Sure glad that's over," Marie said.

"I really need a rest after that," Natasha said, stretching. "I am going to sleep so well tonight."

"One thing, though," Talia said, looking around. "Where's the Gem of Tide? Where did Scylla and Charybdis go?"

Onda and Costa looked at the ground.

"Oh, no," Ruth said. "They didn't really get away with the Gem of Tide, did they?"

The four of them all looked at each other, frowning.

"Pretty Cure Ocean Splash has lost for the first time?" They all said at once.
