Shortly later, Heller was checking on Jonas' blood pressure. But they were staring at each other and still upset about 5 years ago.

"He's in perfect shape." Heller turned to Zhang.

"Just like the last time you examined me." Jonas said to Heller.

And then Mac, Chris and Martin entered the bay.

"Suyin took a glider 15 minutes ago." Mac said. "She's planning on taking the Origin back up."

"Aviva's getting the Amphi-Sub ready." Chris said. "Me, Martin and her for getting ready to go down after her. It's almost ready."

"Take me to the sub." Jonas said and stood up and removes the strap.

"We're not done here." Heller said.

"Yeah, we are." Jonas said. "Lori's running out of air, and we're in international waters. Which means legally I can still beat the ever-loving shit out of you... and get away with it."

Heller turns to Zhang and Mac.

"It's true." Mac nodded. "legally, I mean."

"Definitely not someone to mess with." Martin said.

And then Jonas turns and heads out.

"Good thing he doesn't hold a grudge." Mac pointed.


Outside, Aviva was finishing the Amphi-Sub as it was ready for the long dive.

"Okay, all ready." Aviva said.

And then Chris and Martin appeared with Koki.

"You sure you wanna join us?" Martin asked. "Not that we hadn't done this before."

"Don't worry, my deep sea resistance should be able to withstand the pressure of the Mariana Trench's bottom." Aviva assured. "I was meaning to test it there."

And then, a spouting sound was heard. And they looked below to the water. And sound Bumper's Mom at the surface, and seems to be taking in deep breathes of air.

"What's Bumper's Mom doing?" Koki asked.

"She must getting ready for a deep dive." Chris said. "Sperm Whales always rest before diving. Takes 10 minutes to prepare themselves for the dive."

"Okay, Amphi-Sub is ready to go." Koki reported.

"Okay." Aviva said and steps into the sub and the windshield closed.

"And, I know a way to swim down there." Martin said and brought out a Giant Squid Power Disc.

"Oh, I have something." Chris reached into his pocket. Okay, where is it?" He then he brought out his Creature Souvenir Kit. "I just happen to had a piece of a Squid beak." He then brought out a beak of an Arrow Squid. "Since their both in the Squid family, it might work."

"Thanks." Martin said and inserts the Squid Disc and touches the beak. "Activate!"

And then Martin's Power Suit activates into the Giant Squid Power Suit, and falls in the water. And the Amphi-Sub was lower down into the water.

"I'll catch up with you guys in a minute!" Chris called to them.

"Okay, let's do this." Aviva said and grabs the controls.

And then they both begin to make the long descend to the Trench's floor. Hoping they might catch up with Suyin.

At the loading pier, Chris made his way to Jonas as another sub, Evolution was ready.

"Jonas, you do know that this sub is rated for 12,000 meters, right?" Mac reminded.

"Like the one leaking on the ocean floor?" Jonas questioned.

"Ah. Good point." Mac admitted.

"We good?" Mac asked a member.

"Yep." He replied.

"Once you strip back the safeties and go full manual, like I know you're gonna do." Mac said. "The system's gonna have problems trying to keep up with your pressure changes."

Jonas enters through the hatch, and then he saw a drawing of some Butterflies and a writing "CAPT. BUBBLES".

"Try not to blow your ears out, brother." Mac said.

"Thanks, mate." Jonas grabs an air pump from him.

Jonas drops the bags into the sub as he then climbs inside, and checks the gauges. And turns on the lights, and over at the cockpit was Meiying playing around.

And Jonas soon noticed her. "Hello, Skipper."

Meiying turns to Jonas. "You must be the crazy guy."

"Now who called me that?" Jonas asked offended.

"My mom. Dr. Heller." Meiying answered.

"Yeah, well, I'm not crazy." Jonas sets a small crate down. "I've just seen things no one else has."

Meiying turns back to him. "That's the definition of crazy."

Jonas lightly chuckled. "Backup power. Backup power." He looks around.

Meiying reaches to her left, and flips on a switch. And Jonas was impressed by that.

"So where are your parent?" Jonas asked.

"My mom's trying to bring our friends back from the bottom of the ocean." Meiying turns to him. "My dad's with a Pilates instructor in Taipei. Granddad says Mom needs to move on. But Mom says she needs some more time because she was married to an a-hole."

"Sounds like your mom's got a point." Jonas said.

He then moves to front with a bag.

"You know a lot." Jonas remarked.

"8 year olds hear everything." Meiying smiled.

"Mind if I give it a try?" Jonas asked.

Meiying spins the chair and got off.

"Bye." Meiying said as she heads to the ladder.

And then Jonas moves over to the sit, and turns.

Meiying then halts as she was on the ladder, and turns to him. "Hey, Crazy."

Jonas turns to her.

"Is my mom gonna die?" Meiying asked.

"I'll have Captain Bubbles and your mom back in no time." Jonas replied gently. "I promise."

And then Meiying climbs out the ladder, and Chris helps her out as he soon climbs in and closed the hatch.


In the Control Room, everyone checks on the sub's status.

"Thank you, Emma." Mac said as she gives him a mic.

"Evolution launch, in T-minus 15 seconds."

"DJ?" Mac turns to him.

"Yeah." DJ gave a thumb's up.

"Jaxx, we good?" Mac turned to her.

Jaxx gave a good to go gestured.

"Doc?" Mac turns to Heller.

Heller nodded.

"Evolution... we are go for dive." Mac called to Jonas.


Jonas flips on a switch as the windshield's pads showed "ZHANG OCEANIC". And then turned on as the view of the night sky and the ocean below was seen.

"Fancy." Jonas commented.

And then the sub was lowered into the water, and soon the cables broke off as the sub lands in the water. And nearby, Bumper's mom has finished her resting. And then takes one final breathe of air, and then bends downward and soon her massive tail fluke lifts up and then disappeared under.

"System go for descend."

The sub rests near the surface as Jonas looks down below at the depths below him. And watches as the Sperm Whale pass by diving down, and disappearing from sight.

"System go for descend."


In the Control Room, everyone watches the 360 screen on Jonas.

"Hey, brother. We're good to go." Mac called to him.


"System go for descend."

Jonas remains silent as he watches the depths below.


"System go for descend."

Everyone remained silent wondering why Jonas hasn't descended yet.

"Jonas." Mac called to him.


"System go for descend."

Jonas then grips the control gear, and then after a moment he closed his eyes and moves the joystick forward. And then the sub begins the long descend down.


Soon, everyone saw that.

"Evolution successful launch."

And then the screen shows Jonas turning, and then and made his way to the back of the sub.


Over with Bumper's Mom, she's still descending towards her usual hunting depths.

Her whole anatomy, is designed for diving for long periods. With each breath, Humans replaced only 15% of the air in our lungs, while Sperm Whales able to renew 90% of their breath.

Her muscles are rich in Oxygen-carrying proteins and can store 10 times more Oxygen than Humans.

As soon as she left the surface of the water, the Sperm Whale's metabolism slows down to save Oxygen, and her blood is concentrated on vital organs like the heart and her enormous brain, the largest in the Animal Kingdom.

Her chest cavity is flexible, so it doesn't snap when the pressure mounts. And she has protective mucus that keeps the ribs from sticking onto the organs permanently.

Her huge head, a third of her body length, contains a yellowish wax called Spermaceti. It is believe that whales can vary the density of this substance at will. By restricting the blood supply, the Spermaceti solidifies, acting like a weight and allowing the whale to dive deeper, and with less effort.

The Spermaceti is how the Sperm Whale got it's name, and is why it was one of the most targeted whales during the Whaling Era. Hunted for their oil for some 200 years.

And she can descend 10 feet every second. And she's hardly using her tail at all.

And when she'll resurfaces, the Sperm Whale reheats the Spermaceti, causing it to liquidefy until it is lighter than water. To avoid decompression accidents in the bends, the whale is able to collapse its lungs, while still sending Oxygen into the brain.

So the Sperm Whale can under for up to 2 hours.

And in a single life time, she can make half a million dives. And can cover a distance almost to the Moon.

And is the ultimate free diver.


Meanwhile, Jonas was still descending in the sub.

And readies to place some wires.


And is still watched from the Control Room.

"Evolution now passing 1,000 meters."


The sub soon quickly passes the ledge of the trench.


In the Control Room, Evolution's secondary system was off line.

"Caution. Evolution's secondary systems offline."

Zhang went next to Jaxx and placed his glasses on.

"How is he descending so fast?" Zhang asked about the descending rate.

"Looks like he's diverted all nonessential power like heat and life support to the motors." Jaxx said looking at the screen.

"He's gonna black out." Heller said.

Concern by this, Mac heads over to Heller.

"His blood gases are dropping." Heller gestures to the screen.

"Jonas." Mac called to him.

"Tell Heller I'm not slowing down." Jonas glanced the screen.

Mac then stood up and pats on Heller's shoulder and leaves.


Over 20,000 feet below Jonas and Chris, and another 8,000 from Martin and Aviva.

Suyin was still descending and nearing the bottom.

"Suyin, be advised." Mac called to her. "Evolution is now en route."


"Request you return to Mana One immediately." Mac said.

"Negative."


"He can give us an escort on our way up." Suyin said.


"Tell her to get out of the way, Mac." Jonas called to him. "More people means-"


"-more risk and she's in way over her head."

Suyin clearly heard that.

"Jonas,-"


"-you just told her yourself." Mac said.


Jonas was confused by that. "What?"


"The little green button on your intercom, that's your single channel communication." Mac explained.


Jonas remained silent from that. "Brilliant."


Suyin smirked from that.


"Martin, Aviva you 2 holding up okay?" Koki called to them.

"Feeling a bit squeeze but okay." Martin replied.

"Deep sea resistance of the Amphi-Sub is holding great." Aviva said.


Meanwhile, Evolution continues descending fast as the sonar clicks from Bumper's Mom are now being heard as she was hunting around the Trench's edges.

And sound can travel 4.5 times faster and further through water than air.

And inside, Jonas flips a switch as power is being sent to the sub's batteries. And soon stops at 240%.


"Entering thermocline." Suyin announced.

In the Control Room, the screen shows Jonas moving back to the front.

"Suyin, we're still another mile and a half behind you." Aviva called.


Jonas soon sat down and rotates, but then was feeling a strong tense feeling in his ear as he holds it.

And then grips his nose, to keep his ears from crushing.


Meanwhile, Suyin has finally pass through the thermocline.

And begins to search for the Origin sub.

"Okay, Mac. I am through." Suyin reported.


Meanwhile with Jonas, he released his grip on his nose.

"Warning. Pressure load approaching, 16,000 PSI."

He then saw on his fingers, was some blood.

And the sub begins to jostle a bit.


"At this speed, I'm gonna have to divert power from the heaters and shut down anything that could ice over." Jonas called to them.


Jonas flips a few switches.


"Call you from the other side." Jonas said.

And then a screen showed "WARNING! VIDEO SIGNAL INTERRUPTED".

"You got Wi-Fi here?" Morris asked on his phone.

Zhang glanced at him.


Meanwhile, with the Origin team.

Wall was tending Lori's wound to stop the bleeding. But the screwdriver was still embedded on her stomach. And removing it means a risk she'll bleed out.

"All right." Wall adds a piece of tape over it. "Okay. Just... Just keep pressure on that.

Lori turns to Toshi keeping watch in case the creature is still around.

"Toshi, is it still out there?" Lori asked.

"I can't tell." Toshi said looking through the window. "I can't see anything right now."

It was too dark to spot anything from a distance.


Some distance away, Suyin was still searching around the field of hydrothermal vents for the Origin.

And so far, everything was quiet.

And then fianlly, the Origin came into view.

And Suyin sighs in relief. "There it is. I've got visual on the Origin."


"I can see movement."

"Okay. They're alive." Jaxx smiled.


"I'm going to set up to tow." Suyin said.

And Suyin begins to adjust the gilder into position.

"Range to target. 6 meters. 4 meters. Targeted locked."

Suyin's screen soon showed it was locked on. And then she flips a red switch, and readies her fingers over a button. And the magnetic hooks ready to be fire.

"Firing magnetic hook." Suyin announced. "3. 2."

But just before she can fire, the glider was suddenly struck by something. And felt it was hit by a freight train, and starts spinning.

And Suyin grabs the control stick as she tries to steady the glider.

And soon steadies the glider right side up.


The commotion was picked up in the Control Room.

"Suyin? Are you okay?" Mac called. "What's happening?"

"There is something down here." Suyin called knowing she isn't alone with the Origin. "Something just hit my ship."


Suyin looks around to see what struck her.

"Suyin. Look around you." Chris called to her. "Can you see anything? Anything at all?"

Suyin looks around the area, trying to spot whatever struck her. But it was too dark to see anything from a distance.

Everything was quiet and calm for a few moments.

But then suddenly, a large tentacle with serrated teeth like structures on it's suction cups slams over the glider causing Suyin to jump. And then another tentacle wraps onto the glider. And is joined by 8 more.

"Suyin, what's happening?" Mac called to her.

"It's a huge Squid." Suyin said. "It's got the glider."

Behind the glider, a Giant Squid has caught the glider in it's tentacles. And thinking the glider is a prey source.

The screen then showed "PRESSURE WARNING".

"Warning. Capsule pressure."


Everyone in the Control Room was now concern.

"Mac, it's crushing. It's crushing me! I don't think the glider can take it."

"It's not gonna hold." Jaxx said.


The Giant Squid's grips harder with it's tentacles as they grip harder like a Green Anaconda wrapped around a helpless Caiman.


Everyone watched as it's grip got stronger.

"Suyin,-"


"-engage the pressure compensator."

Suyin tried engaging the pressure compensator. But there was no response as she frantically tries.


"Compensator will not engage."

"Capsule breach 10 seconds."

"I can't watch!" Jimmy covered his eyes.


Suyin was helpless as the Squid's grip continues to strengthen around the glider.

"Capsule breach in 5 sec..."

Then suddenly, strangely blue Squid blood spews through the water. And then the tentacles loosen their grip as the suction cups were pulled back. And some of them looked they were bitten off by something.

Then suddenly, emerging from the dark and Squid blood was what looked like a giant mega-sized Great White Shark with the Squid's dead body and mantle in it's mouth. And Suyin watched as the Shark swims overhead and it's teeth looked 6-7 inches in size.

"It's a Shark." Suyin breathless gasped.


"It's like 20, 25 meters."

Jonas knew there was only Shark that can grow to that size.

"It's Megalodon." Jonas said.


"Impossible."

Everyone in the Control Room was completely in disbelief.

"I'm sorry, did he say a Megalodon?!" Koki exclaimed.

"As in, the giant Shark?!" Jimmy said.

Megalodon was one of Earth's most legendary predators. It stalked and terrorized the Earth's oceans for 20 million years, and vanished from the Earth at the dawn of the Ice Age.

And then Jonas turn the screen, almost looking at Heller. "I'm so glad I'm not crazy."

Everyone remained silent.


Tens of thousands feet below the surface, Martin in Giant Squid Power, the Amphi-Sub and Evolution came through the thermocline.

"Suyin, power down." Jonas called. "It's drawn to the light. Shut everything down and stay dark."

Martin quickly blends in with the surrounding darkness. Since Squid have chromatophores in their skin to change color and to camouflage. And that Aviva added that feature into the Power Suit.

Aviva quickly flips a switch, and then the whole Amphi-Sub became invisible after she installed a feature of Dragonfish spy-mode cloaking she added sometime after the Creatures of the Deep Sea adventure. And hopes that even a Megalodon won't detect.

Suyin quickly begins to shut down the glider.


"Shutdown in 30 seconds."

Everyone watched silently.

"Shutting off everything but comms."

The screen made an alarm as the shark is circling back and clearly still hungry.

"It's circling back. Here it comes, Suyin."


Suyin waited for the shutdown to finish.

"Shutdown in 25 seconds."

"Suyin, there's-"


"-no time." Jonas said. "Turn off your lights."


Suyin quickly flips the switch to turn the lights off. But strangely they stayed on.

"Shutdown in 20 seconds."

"Turn them off. Now." Jonas called.

Soon, the Megalodon was coming into view.

"Shutdown in 15 seconds."

"Suyin, what are you doing in there?" Chris called to her. "Turn them off, now!"

"I'm trying!" Suyin frantically trying to turn the lights off.

"Suyin, what's going on in there?" Aviva called.

"Mac,-"


"-I have no control." Suyin called.

"It must gotten damaged from the Squid." Koki said.


It appears the glider has taken serious internal damage from the Giant Squid. And is now unresponsive.

Suyin continues to get the lights turned off.

"Hurry." Jonas called.

"10, 9, 8, 7, 6, 5..."

Suyin then turns to her right and saw the Megalodon fast coming at her. But then at the last second, a bright flash of light appeared as the Megalodon then swam over her.

And then the Shark follows a trail of underwater flares as Jonas deploys a trail. And he and Chris watched as the Megalodon swam by them, and luckily it didn't noticed them.

"Whoa!" Chris breathless said watching it go.

"Now's your chance." Jonas called Suyin. "blow your tanks!"

"No." Suyin denied. "I can help you-"


"-save the crew."


"Your glider's damaged. There's nothing you can do."

"He's right, Suyin." Chris called to her. "It took too much internal damage from the Squid."

Suyin felt uneasy of leaving, but knew they were right.


"Blow your tanks now!" Jonas said.


And then given no choice, Suyin reaches her ballast tank lever.

"Damn it." She cursed and pulls it.

And then the tanks blew, releasing a gust of air bubbles. And Suyin's glider started rising upwards as Jonas, Chris, Martin and Aviva watched.

And soon, she disappeared through the thermocline.


"Dr. Zhang, your daughter's clear. Heading for the Origin now."

"Koki, stand for repairs." Aviva called. "Her glider is damaged."


The Evolution sub slowly and clearly lowers down to the Origin as Aviva controlled the Amphi-Sub's robot arms to keep it still. And as Martin stood by.

"Range to target, 3 meters."

Jonas carefully adjusts the sub as it nears the Origin's hatch.

And soon, it lands on top of it. And Jonas pushed a button on the screen to clear the water.

And then Jonas towards the hatch and waited.

"Water extraction complete."

Jonas then opens the hatch as it drops aside. And he and Chris saw the hatch's handle badly damaged and bent. And as well as a bent pipe.

"Oh, they weren't kidding about severe." Chris said.

Chris then hands Jonas a blowtorch, and he begins to reach down towards the handle and begins to remove it.

Hearing the blowtorch, Wall and Toshi begin to help Lori up.

"Let's do this, sweetheart." Wall helped her up.

Soon, Jonas was able to snap the handle off.

And Wall gently helped Lori to her feet.

Then Chris handed Jonas an air pump, and once Jonas had it secured. He begins pumping it to fix the bent pipe.

Soon Wall bangs over the hatch as Jonas removes the pump. And then quickly grabs a wrench and taps on the hatch.

"Open up!" Chris called.

Wall turns the handle, and lifts the hatch open as a bit of water spilled into the sub. And they soon saw Jonas and Chris as Jonas lightly laughed.

"Hi." Chris waved.

Lori sighed in annoyance from his ex-husband being the last person she expected.

"Tell me this isn't the world's best "I told you so"." Jonas said.

"You came all the way here just to tell me that, didn't you?" Lori asked.

"Pretty much." Jonas answered.

"How bout we save it on the surface?" Chris suggested. "And away from the giant Shark that's outside?"

"Give me your hand." Jonas extended his hand down.

He soon grabs hold of Lori, and he begins to pull her up. And Jonas soon saw the injury on her.

"Ah, that doesn't look good." Jonas said. "Ready? 1, 2, 3."

And then Jonas helps her in, but then suddenly the sub's alarm rang as they turned to the front. And on the radar, it showed a large object coming at them, and clearly it's the Megalodon.

"She's coming." Jonas said.

"Uh, oh." Chris said.

"Let's move." Jonas quickly pulls Lori to the front of the sub.

"Martin, do you have visual on her?" Chris called.

"1 '0 clock! 1,000 feet and closing!"

"You and Aviva clear out, now!" Chris said.

"If that thing hits us while we're still attached..." Lori said.

"The we're all gonna die." Jonas said.

Jonas quickly moves back to the hatch.

"Okay, who's next?!" Chris called.

Outside, the Megalodon was closing in on the distance with the 2 subs.

In the Origin, Toshi quickly helps Wall through the hatch.

"Come on, I've got ya." Jonas said grabbing his hand.

Toshi looks over to the screen, and saw that the Megalodon was closing in fast.

"Guys, hurry up in there!" Aviva called.

"We're hurrying!" Chris exclaimed.

"It's gonna be close." Jonas said. "Come on, move, move!"

Seeing how fast the shark was coming, Toshi was left with a difficult decision. He quickly grabs his notebook, and rips off the letter for his wife. And stuffs it into Wall's pocket.

"Go! Go! Go!" Toshi quickly pushed Wall out.

"Aviva, Martin! Get outta here!" Chris yelled.

Jonas and Chris quickly pulled Wall in the sub.

"We're not gonna make it!" Wall yelled.

Wall was soon in.

"Toshi, give me your hand!" Chris moves towards the hatch.

"Toshi, hurry!" Wall called.

Then suddenly, Toshi closed the hatch and locks it.

"Toshi, no!" Wall exclaimed.

"Toshi, wait a minute!" Chris moves to the hatch.

Toshi quickly closed the Origin's natch, and then quickly pulls a lever.

And then Jona's sub detaches from the Origin, and the sudden large burst of bubbles was enough to frighten the Megalodon as she swims away.

And Martin and Aviva quickly made a break for it.

And the sub raises upwards as the Shark swims off.

But then, Toshi moves over and flips a switch. And then the lights of the sub turns on.

And the Megalodon saw that, and circles back making a beeline towards the Origin.

Toshi sit in the cockpit's sit and reaches his mic. "I'm sorry."

And he looks up as the alarm beeps as the Megalodon quickly closes the distance.

And then, Toshi let out one final scream as the Megalodon emerges from the dark with her open jaws.

And then with the force of a runaway freight train, the enormous jaws of the Megalodon clamp down on the sub. And drags the sub across the seabed, and hits a hydrothermal vent causing it to go off.

In the Evolution sub, they all watched as the vent spews out a jet of lava as the Megalodon swims away from view. And with the Origin in her mouth, and likely eaten if the water pressure hasn't got him first.

And everyone remained silent as Wall and Lori were in tears of their friend gone.

"Come in, Evolution." Mac called. "Jonas, come in. Are you all okay?"

Wall then felt something in his pocket, and pulls out Toshi's letter to his wife.

"Dr. Heller has vitals on Lori and The Wall, but we don't have Toshi. Is Toshi okay? Jonas, is Toshi okay?"

And the team of 2 subs, and blue and black Giant Squid begin the long trip up.


Author's Note:

The Wild Kratts meet the most legendary Shark that has ever existed.

In real life, the temperature is nearing below freezing at the bottom of the Mariana Trench. And Megalodon is believe to be cold blooded. So it would likely wouldn't last long even it can withstand the pressure which is 15,750 PSI.

And who was shocked about Notre Dame going up in flames yesterday?

A cathedral that has been around for 850 years. Survived and witness many conflicts, both World Wars, made famous hits in Cinema History. And was based in the story The Hunchback of Notre Dame.

Let's hope it can be restored.
