Meanwhile, at Splatsville

BGM: Crazy Cap Shop (Super Mario Odyssey)

"Hmhmhmhm~" Frye hummed as she was walking with a few of her small cousins at the Barnacle & Dime Mall.

"Can we stop over at the food court later?" One of her cousins asked.

"Whatever you want!" Frye grinned as they continued to wander around the mall with a few bags in her hands. She had decided to take some time for herself and spend some time with her family after the last Splatfest.

Sure, she had won the Yaki Splatfest and was happy that it should be called Oban-yaki compared to Katten-yaki and Imagawa-yaki, and she had felt pretty confident with the Handshake vs Fist Bump vs Hug Splatfest that went on immediately after that one, especially considering Fist Bump dominated… but to her dismay, Shiver snuck up behind her and pulled through with only three points.

To say that she was a bit devastated, especially for Big Man who didn't get anything in that Splatfest was an understatement… and she was also a bit fatigued since they tend to spread out Splatfest but they decided to try a Doublefest in a row.

A girl can only perform Anarchy Rainbow for so long before her legs give out.

Once she helped with the announcements on the stages for Turf Wars and Anarchy Battles, she decided to take some time for herself. As far as she knew, there was nothing scheduled for Barnacle & Dime, so she called up a few of her cousins and went on a shopping trip.

She didn't know what Shiver and Big Man were up to, but she was pretty sure they were taking it easy as well.

A few fans of her waved to Frye as she waved as she possibly could as she walked into a store with her cousins, and then came out with even more items. Sure, her arms were killing her but if it meant spending time with the little squid kids, it was worth it.

Suddenly… the ground started to shake violently.

End BGM

"Whoa…!" Frye said in surprise, nearly catching herself.

"F-Frye! What's going on?"

"We're probably just having an earthquake!" Frye said.

"Look!" A male Inkling called out to the center of the mall, AKA the biggest fountain known to squidkind and where the Inklings and Octolings battled to their heart's content.

A geyser went up, followed by another… but these geysers were different. They weren't your typical fresh and clear blue waters… they were sludge green as Salmonids started to pour out.

"WHAT THE CLUCK?!" Frye yelled in disbelief as the residents cried out in terror… since they didn't have any weapons on 'em so they started running around in a panic. She turned to her cousins. "Quick, get on my shoulders!"

With a nod, they quickly hopped on as she dropped her bags, pulled out her phone and located where Shiver and Big Man were at, and then squid jumped straight for them right as a Flyfish started firing missiles everywhere.


Meanwhile…

"Ay?" (You sure you don't want some Mint Chip?)

"Nah, I'm good." Shiver responded, eating some vanilla ice cream.

Big Man looked up in the sky to see Frye coming in for a landing. "Ay!" (Ah, Frye's back!)

Frye landed near them. "Hey, how was shopping at-"

"We need to alert Grizzco!"

"Huh?" Shiver tilted her head. "What do you mean? The Salmonids are all under control. I mean, it was well contained in Undertow but… Um'ami Ruins was a bit messier than that, especially with more of those Cohozuna and Horrorbor-"

"They're invading Barnacle & Dime!"

"What?!/Ay?!"

"We need to alert them NOW."


Meanwhile, at Grizzco…

"Soooo, let me get this straight… you want a bigger paycheck because of your Shell-Out Machine gambling addiction?" Ikura asked.

"Yes!"

Ikura sighed exasperatedly. "Get out."

The pink female Inkling walked out of the door, grumbling to herself and mumbling "Greedy business squid and "worse than Mr. Grizz himself"."

"Don't feel too bad about it." Cordelia said. "At least you're handling it better than that cat."

"I still can't believe Lil' Judd tried to make himself at home…" Ikura shook her head. "Glad we nipped that in the bud and don't have to worry about him assassinating Judd."

"Speaking of which, what ever happened to Lil' Judd?"


Meanwhile…

Tom Nook casually sat on a lawn chair next to a female Villager, both of them getting a tan… while Redd ran away in terror.

"GET BACK HERE, YOU FRAUD!" Lil' Judd yelled.

"WHY DO YOU PEOPLE ALWAYS BRING IN THE WEIRDOS!" Redd yelled.

"I'm not the one selling fake Mona Lisas." Tom Nook said.

Isabelle walked by. "Hey guys, brought a friend over!" She said as Tom Nook looked up to see Doom Guy next to her.

"Oh, hello mister Slayer. Pull up a seat! Brewster should be coming back with more coffee, yes yes!"


Back in Splatsville…

"I think he was taken to another world called… Animal Paradise or something?"

"Huh, good for him."

At that moment, Deep Cut burst in. "Oh, hello Deep Cut!" Cordelia smiled.

"Cordelia? I wasn't aware you were here for a visit." Shiver said.

"Ayyyy~!" (Hi, Mrs. Brooks~!) Big Man smiled with a soft blush, happily hugging her as she grinned and hugged him back.

"Oh, this isn't the time for hugs!" Frye exclaimed. "We got a Salmonid emergency!"

"What, did they destroy the Hydroplant?" Ikura asked.

"No! It's worse than that… Barnacle & Dime just got hit!" Frye said.

Ikura's expression darkened. "...Oh…" She immediately stood up. "Cordelia, suit up. I'll alert the Squidbeak Splatoon."

"Right." Cordelia nodded as Ikura hit a button on a wall as sirens blared all over Splatsville.

"ALERT. ALERT. SALMONIDS ARE INVADING THE BARNACLE & DIME SHOPPING MALL. ALERT. ALERT."


Meanwhile, in Toad Town…

BGM: Toad Town (Mario and Luigi: Bowser's Inside Story plus Bowser Jr's Journey)

"Dude, you think that'll be enough for your girlfriend?" Coco asked.

"Well, yeah, obviously!" Sun nodded.

"I dunno… Blake doesn't strike me as a necklace type of gal…" She mused before shrugging. "Eh, maybe she does and I just never noticed."

"That's a first." Velvet teased.

Coco chuckled. "Eh, what can ya do." She said as her scroll started to vibrate, as did Velvet and Sun. They looked into their scrolls to see what it was.

URGENT: Calling all members of Squidbeak Splatoon. Salmonids are invading Barnacle & Dime.

"Welp, I've got nothing better to do. Let's rock." Coco said as they nodded and took off, with the rest of SSN, FY, Nagisa, Jataro, Junko, Mukuro, Mondo, Chihiro, Leon, Ink Fresh, Oobleck, Namine, Komaru, Toko, Magnolia, Nick, Logue, Becky and the Badland Mercenaries accompanying them.

End BGM


Later, after meeting up in Splatsville…

"Oh look, there they are." Marie said as she, Callie, Ribbon and Octavio were waiting for them.

"We got the news… wait, aren't we missing two?" Coco asked.

"The Captain and Azure are already assessing the damage, we just got here." Callie said.

Cordelia walked out wearing a red helmet with a built-in headlamp instead of just being strapped on where it also had a visor. Her gloves were skin tight and fingerless for better holding of weapons, with knee high green boots and had a semi-loose yet firm Hazmat-like suit.

"Right on time as I had just finished preparations on this." Cordelia said.

"I got the choppers ready. Let's go." Ikura said with all of them nodding.


Meanwhile, at Barnacle & Dime…

Azure swiftly tore through a few Small Fry that made their way into the clothing districts, one of them running out with a bra over their heads but was quickly stepped on by Azure. "No respect for fashion…" Azure shook his head, turning around and shooting a Cohawk until it was destroyed.

One snuck up behind Azure, ready to smack him silly with a frying pan… until it was completely flattened by a Triple Splashdown courtesy of Captain Three.

"Oh, thank you!" Azure smiled.

"We gotta find a way to clear up those geysers." Captain Three said.

"Got any ideas? Because I'm not the best swimmer out there."

"Neither am I."

At that moment, several helicopters came flying in through a hole in the skylight as everyone hopped off and landed on the ground.

"Alright, some of you find any stragglers and get them to evacuate. Some of you guys deal with the Salmonids… and well, the rest of you guys go to the main source and figure out how to seal those geysers shut." Ikura ordered. "We can't let this mall fall to these things!"

"Let's go!" Cordelia said, vaulting over a railing as everyone went off.

"Honestly, this is just me, but I definitely prefer Arowana Mall." Callie said.

"Eh, this one's bigger and more popular." Marie said, getting into position and sniping some Cohawks.

BGM: Bait & Click (Splatoon 3)

Hopping into the main center was CFVY, Azure, Ribbon, Mukuro and Komaru.

"We'll try to plug the holes up!" Oobleck called out to them as he went to work with Junko, Heavy, Engi, Toko, Chihiro and Nagisa.

"I don't care if you guys get the golden eggs in the basket or not, I ain't greedy like the furball. Just make sure the Salmonids are secure!" Ikura said, shooting at a few stragglers.

Ribbon pulled out her Tri-Stringer. "Alright, let's splat these suckers!"

They proceeded to mow down the Chum and the Cohawks as Velvet ducked underneath a Cohawk's frying pan and punched it away with Yang's Gauntlets before switching it up to a Splatana Stamper and cut through the Cohawks.

At that moment, a Steelhead emerged with a few Scrappers and a Steel Eel, the latter already blowing up since Yatsuhashi was near it and destroyed the driver, then he tossed the eggs into the basket.

The Steelhead charged up and threw the bomb down at them, only for Fox to punch it back and had it explode in the Steelhead's face to kill it while Azure snuck past a Scrapper and shot it from behind.

As the Boss Salmonids were getting destroyed, several Snatchers came in to try and pick up the eggs… only to get picked off from railings courtesy of Marie and Sniper, both of them fist bumping on a few occasions.

In the water, the others were busy trying to plug up the holes as Engineer was making some makeshift buildings to seal them up.

"Huh…?" Chihiro wondered as he looked at a device he was holding.

"What's up, pardner?" Engi asked.

"I'm getting readings of some movement coming from below us, and it's a big one."

"Probably a wave of little Salmon babies." Heavy said as Nagisa took a look.

"No… I don't think it's a "little Salmon baby"..." Nagisa said. "Think you can keep an eye on it?"

"Will do." Chihiro nodded as Junko sealed up the first Gusher.

"There we go!" Junko said… only for another to pop up. "Augh!"

"I was afraid of that." Engi mumbled.

Below Mukuro as she was busy taking out some Chum, a light lit up underneath her as she looked down, only for a Maws to come up, but she spread her legs as her feet were on both sides of the jaws. The Maws tried to bite down, but was annoyed when it couldn't eat her up.

"Here ya go, big guy." Mukuro said, dropping a grenade into the creature and backflipped off as the Maws exploded while Mukuro gracefully landed as a Stinger aimed at her, only for Komaru to shoot it down with her Luna Blaster, save for the head.

The head of the Stinger started to sweat nervously as Komaru picked him up and proceeded to use it against it's own brethren, destroying a few Flyfish and cutting through a Big Shot's stomach that cut him in half, while also going through a Fish Stick's tower that fell and crushed some Chum that swam on by.

By the time Komaru was done, the Stinger was out of juice. "Aww…" She pouted before tossing it behind her.

With the others, Oobleck and Toko put the covers on the gushers with some help from Heavy and Junko, but more just kept popping up. "You gotta be kidding me…" Junko said.

"Mmmm… whatever this thing is, it's getting closer…" Chihiro grimaced.

At that moment, a Salmonid Mothership arrived and started to let loose its Chinook henchmen to overwhelm them, but the Chinooks didn't even have time to bring down some Chum and Cohawks as they were quickly sniped down by CFVY and even Marie and Sniper provided backup.

The Mothership tried to home in on them, but was quickly shot down and crashed into the fountain when Coco let 'er rip. "Nice try!" Coco smirked as they went back to dealing with the rest of the Boss Salmonids.

Back in the fountain, Heavy had the idea to climb in and grabbed the mothership and placed it down on one of the gushers, sealing it up. "Nice one, big guy!" Engi praised as he continued to build more as everyone went and sealed up the remaining Gushers.

"It's done!" Junko smiled as the ground rumbled underneath them.

"It's getting closer! It's right on top of us!" Chihiro warned.

"How much longer?" Nagisa asked as the quakes started to increase.

"Not long enough!"

"Okay, move it!" Engi yelled as they evacuated the fountain as the quakes were enough to make CFVY and the others stumble.

End BGM

The mall shook violently as everyone held onto something for support. Whatever this was, it wasn't a Mudmouth event… nor was it a Cohozuna or a Horrorboros rearing their ugly heads.

A large King Salmonid burst through, opening its large mouth. It looked like a giant Maws ready to chomp down and take a piece of the Earth with it.

"Holy… dooly…" Sniper whispered in awe.

BGM: Vs Boss (Super Mario Sunshine)

We're Gonna Need a Bigger Splat Bomb - Megalodontia

"I've heard of this Salmonid in passing… a Megalodontia." Cordelia said.

"That sounds like a mouthful. Can we just call it "Joe" for short?" Sun asked.

"That's way too generic…" Namine said.

"Look, "Joe" rolls off the tongue better than THAT thing!"

"Maybe "Joe Maw Maw"?" Azure chuckled at his own joke.

Ikura stared at the Megalodontia, her eyes widening in horror as she flashbacked to when a Maws ate up her best friend. Her legs trembled as she put her hands over her mouth as her knees gave out as she fell flat on her butt, frozen terror had replaced her determination.

She put her hands over her head, closing her eyes as she tried to block it out as Megalodontia screamed.

Cordelia turned to Ikura, seeing her in her state as she clenched her fists. "You're not going out that way…" She drew out her sword. "Not if I have anything to say about it."

She vaulted over the railing. "Someone make sure Ikura's taken care of!" She said over the radio as Namine ran through and quickly set up some Blizzaga barriers along with a few Ink Turrets on stand by, all of them aiming at Megalodontia.

Marie put her finger on her ear piece. "Sheldon, do you copy?"

"Loud and clear. I'm seeing the news on TV. Need anything?"

"Think you can make a large Splat Bomb?"

"I'm gonna need to find some outside resources for that one… because I got an idea!"

"Hurry then!"

"Right!"

Megalodontia went back underground as the ground underneath CFVY rumbled, signaling that they needed to get the heck out of there as they rolled out of the way right as Megalodontia sprang up to chomp down, but chomped down on a Slammin' Lid and a Flipper Flopper.

"It's eating its own kind?!" Velvet paled at the thought.

"This thing will stop at nothing…" Coco whispered as she noticed a big red bump on it, complete with a bandage over it. "...You gotta be kidding me." She smirked as she directed her attention toward it and fired.

The Megalodontia sunk back underground and then re-emerged nearby, tearing through an upper floor and destroying the stores around it as the Mercenaries proceeded to fire upon the creature, and then Becky came in from below and let out a scream, striking its weak point as Megalodontia roared before going back under.

As the Megalodontia got closer to a PTSD-stricken Ikura, the Turrets opened fire while back at the fountain, Heavy gathered up several cannons from the Big Shots and then fired multiple eggs at the big guy.

Another Big Shot came up, only for SSSN to beat it up as Sage picked up the cannon. "Heavy! We got another one!"

"Good!" Heavy nodded.

Namine backflipped, avoiding the Megalodontia's jaws as dark paint swirled around her as she launched Painbrushes at the weak spot along with a healthy dose of Thundaga on the weak spot as Ikura climbed up on some debris and opened fire with her Tri-Stringer.

"Hey kid! Amplify your screams with this!" Octavio said as Becky nodded. "We'll remix that big boy's face!"

"Yeah!" Becky nodded and let out a massive Killer Wail scream that knocked the Megalodontia back as Deep Cut and Ink Fresh fired at the dazed monster with Soldier rocket jumping and firing rockets into his mouth.

Megalodontia got back up and sunk back underneath… and then came up near Chihiro and almost ate him up, only for Mondo to come out of a motorcycle shop and drove off a platform as he jumped off and struck the weak point.

"Maws off my little bro, ya demon!" Mondo said.

Megalodontia sunk underneath and came back up near Cordelia, where she proceeded to climb up its netting… and went for a swim as it went back underground and came back up, chomping on a few Steel Eels. Cordelia shook it off and climbed her way up, making sure to stab the Salmonid at every opportunity she had.

Azure took a running start off of a platform and then proceeded to shoot at the beast, corkscrewing his way down that caught Marie's attention. Midway down, Azure came face to face with Marie as he gave her a wink as he zipped by and landing in a Big Shot's cannon and launching his way toward the big Salmonid.

"What a show off… but he's my show off." Marie smiled.

Megalodontia sunk back down and started to re-emerge underneath Captain Three. She quickly activated her special as Megalodontia chomped her up… only for "Kracken Three" to sneak out of its mouth and corkscrewed into its weak spot for good measure as she harmlessly flopped to the ground as the Kraken special disappeared.

"Nice try." She smirked.

Azure proceeded to go all out on Megalodontia, even proceeding to unleash a move similar to Dante's Rainstorm attack.

And in Toad Town, as the Big Run was being broadcast over there, Dante had witnessed Azure's move on it.

"Hey, wait a sec!" He said, pointing to the TV. "THAT CALAMARI IS A GUNSLINGER!"

"Did someone spike your Strawberry Sundae again?" Nero asked. "There's no way that-"

"Let's get a replay on that awesome move from Agent Four! Talk about finesse and grace!"

"...Holy shit, you weren't lying."

"Told ya!"

Back at what's remaining of Barnacle and Dime, a large helicopter came flying in a few moments later.

"Huh?" Coco wondered as the helicopter flew above the Megalodontia, as the large Salmonid spotted the machine as it dug underground and then breached to the surface right as a hatch opened up as a gigantic Splat Bomb dropped inside.

The helicopter flew away in time as Megalodontia chomped down right as Cordelia stabbed it in the eye… and then the giant Splat Bomb exploded inside, making the Megalodontia explode as well, sending guts flying everywhere as Cordelia landed gracefully.

End BGM

"You're welcome! I was pretty lucky finding a Mega Mushroom so quickly!"

"Thanks Sheldon!" Marie smiled.

Cordelia walked over to Ikura, brandishing her sword and knelt down as Ribbon and Namine came over to her. "Hey…" She said gently. "It's over. The big guy is gone."

"It… it is…?" Ikura looked up and breathed a sigh of relief as Cari jumped out of Ribbon's bag and nuzzled against Ikura's neck. "Oh thank squid…"

"We're definitely gonna have to close this place up and rebuild." Cordelia said.

"Agreed." Ikura nodded. "Thank you everyone. If we have another invasion, we'll let you know."

"Will do!" Coco nodded with a smile. "Come on guys, let's go ahead and help clean up."

"I'll help with rebuildin'." Engi said.


Later, back at Grizzco…

"Okay, so… a lot of Inklings and Octolings came to help out, I've noticed that." Cordelia said.

"Yeah, I was planning on paying them." Ikura agreed as she hit the "Send all" button on the squids that helped out.

…Only to be met with angry Squid tweets.

"Um… people are upset with gaudy green trophies."

"What?" Ikura wondered with a tilted head. "I could've sworn I sent out Bronze, Silver and Gold trophies."

"Let me look into it…" Cordelia said as she looked through the system. "...Aha! Found the problem. Apparently the big ol' teddy bear's old system overrode the new system, hence why those gaudy green trophies were sent out instead of the new ones we made."

Ikura's eye twitched. "You mean… even in space and in death, the big guy is STILL screwing me over?"

"Unfortunately."

Ikura groaned, putting her hands over her face as she leaned back on her chair, with only one word coming out of her mouth,

"Broomy…"


With the recent Big Run finished up in Splatoon 3, I thought it'd be fun to do a fun Gaiden all about the Megalodontia! ...Or Joe as the Japanese Splatoon Twitter account called him for some reason.

Ibuki: Still funny~!

Deadpool: Talk about a big boy!

Indeed. Oh, and a fun little Easter Egg: Captain 3 using the Kraken to escape the jaws of death from Megalodontia? That was referencing a moment I had with the big guy in the Big Run. I panicked when I couldn't get away in time so I activated it... and was thrown into his mouth, but the Kraken saved me. Wanted to reference that moment! (Unfortunately, I didn't corkscrew into his weak spot. Wah wah...)
