So if you guys are like me, then you would also have a terrifying fear of the ocean.
So today we're gonna get to the bottom of it.
Yeah, something about it being like a bazillion kilometers deep,
and to this day, we still have no idea what lives down there, really scares me.
I got my adult diapers on everybody,
and judging by this thumbnail, it looks like I'm gonna need it.
Subscribe for that awesome pun, by the way.
By the way, huge shout out goes to MysteriousFact for the video.
Have you ever wondered what's hiding in the 80% of the ocean's floor?
Oh my god, oh my god, oh my god.
Bro, we're three seconds in.
This looks like those giant shadows that was cast on the ocean
before the straw hats entered Skypiea in One Piece.
Come on, bro. There's no way that's real.
What if some sea monsters from Legends were actually real hiding there?
No.
Today we're looking at 10 mythical sea creatures that really existed.
Four of them showed up in my older video.
Four of them?
But six are totally new discoveries.
Okay, I just caught a quick glimpse of those four that actually existed, guys.
There's no way, right?
This is clickbait.
Surely this is clickbait.
My adult diaper is already filled, guys.
I gotta change this already.
So stick around.
The craziest ones are waiting at the end.
Okay, nah, you're lying, bro.
Yo, that's straight out of God of War.
I played that mission.
Number 10, Kraken.
As far back as the 12th century, sailors and people living near the sea
told scary stories about the Kraken, a giant sea monster that looked like a squid.
They said it attacked ships and pulled them underwater.
What?
No.
The story probably began in the waters around Norway, Iceland, and Greenland.
Nah, nah, nah, nah, nah, nah.
Norwegians, Greenlandians, Icelandians, whatever you call them.
Okay, y'all are tripping.
No way this thing actually exists.
I don't believe it.
Okay, what did they find?
An 800 feet octopus fossil somewhere?
These things don't even have bones.
You can't prove to me they're real.
There's no way.
Spoke of a huge creature with long arms that could grab whales.
Long arms?
You mean tentacles?
Wait, wait, wait.
Stop, stop, stop, stop, stop, stop, stop, stop.
Back up, back up.
Long arms that can grab what?
Spoke of a huge creature with long arms that could grab whales.
Whales?
These krakens were grabbing your mom?
Guys, that's kind of messed up, don't you think?
Yo, gotta insert a yo mama joke at least at some point.
We gotta lighten the mood a little bit.
Okay, this is scary.
Can we admit that this is scary?
If you didn't have a fear of the ocean before, I hope this is unlocking a new fear in you.
Huge creature with long arms that could grab whales or smash large ships.
The kraken didn't just attack.
It pulled ships down and made a strong whirlpool that sank everything and everyone aboard.
Like many old stories, this one was probably made bigger and scarier over time.
But the first report of someone seeing the kraken goes back to the year 1180.
At that 1180, some random drunk Norwegian Viking said he saw the kraken.
Everybody believed him.
Come on, bro.
Others didn't know about giant squids.
So when they saw something strange in the water-
Oh god, oh god.
That ate people.
But what if the stories were true?
In 1853, something big washed up on a beach in Denmark.
It was a-
Guys, I'm gonna go put chlorine in my eyes real quick.
We'll be right back.
Nah, nah, nah, nah, nah.
Nah, nah, nah, nah, nah, nah, nah, nah, bro.
That's not a real photo.
No, there's no way.
That's not a real picture.
Tell me that's not real.
The first time something like that had been seen up close.
And it looked a lot like the kraken.
That's real?
Since then, scientists have asked how many kinds of giant squid exist and how big they can get.
But can any of them reach the size people talked about in the past?
Think about this.
Animals like the megalodon and nothosaurus were real.
Shout out fish.
Megalodon, you guys already know.
Roblox.
Wait, wait, wait, wait, wait, wait, wait.
This thing right here was real.
Guys, do you still think I'm crazy for thinking this ocean is scary?
And these are just confirmed what we know was real, bro.
Nobody's been to the bottom of the ocean to actually find out.
And the biggest squid found so far was 43 feet long, about 13 meters.
Dude, stop.
But that's not all.
In 2011, scientists found...
Wait, wait, wait, wait, wait, hold on.
2011 or 2012, bro.
What year was it?
Make up your mind.
Scientists found bones from very old sea reptiles.
The bones were placed in a strange way.
Some scientists said only a huge octopus or kraken-like squid could have done it.
One scientist, Professor Mark...
Oh, like it got squished.
Like all the bones kind of got crumbled up and squished up.
Is that what they're saying?
Because like these octopuses be just like wrapping their tentacles around and...
You know how octopuses work, okay?
Are we ****** right now, bro?
That's not the same guy.
That's not the...
Why would you put a picture of this random scientist over here when you...
What?
Professor Mark McMenamin has spent years trying to show that these giant squid were real.
He looked at the bones of a sea reptile called a...
Yeah.
Shonisaurus.
Oh my god.
Even that thing's scary.
He also saw marks that looked like they were made by squid suckers.
Oh my god.
The neck looked broken.
So he believes something...
What?
The way the bones were placed is like how today's octopuses pull food to their homes.
But this sea creature...
That's so disgusting, dude.
Bro, bro, bro, bro, bro, bro, bro, bro.
People eat octopus and squid, by the way.
They're literal sea aliens.
I swear they're actual aliens that just landed into the ocean and decided to live there.
...eat that big reptile.
That's more than twice the size.
It would have had to be over 30 meters long to kill and eat that big reptile.
That's more than twice the size of any squid we've ever...
Oh, it's huge.
It's huge.
30 meters?
...from sailors might not be all made up.
And the deep ocean, which we still don't fully understand, could have...
That's the thing.
...still is home to a...
Oh my god.
What's that fear of like very large things?
It's like mega, mega, mega something phobia.
Comment down below if you know what I'm talking about, bro.
That last scene right there just made me pee a little bit more.
...or maybe still is.
Look at this.
That's the boat.
Those are the tentacles.
Number nine, Leviathan.
Leviathan...
No, man.
No, no, no, no, no, no.
The Leviathan didn't exist.
Don't lie to me, bro.
Please.
Leviathan wasn't just a myth.
No.
Oh, there you have it, guys.
It was in the Bible, so it must have been real.
Okay.
Yeah.
Oh.
Bro.
Look at these pictures.
Does that not just give you like literal goosebumps, bro?
Why?
Oh, that's a long time.
Okay, is that that big?
Oh, that's big.
Oh my god.
But to be fair, it's not bigger than a Leviathan, so we shouldn't be too scared of it, I guess.
Why even scared of a thing that has no legs and arms?
Like it can't even hit you.
95% of the ocean is unexplored, guys.
All the weird that we've seen that have confirmed exists is only 5% of it,
which means something that's much worse than the Leviathan probably is down there somewhere, bro.
That is the-
Oh my god.
That makes me sick.
A whale?
Levitar?
Dude.
And whales have like a million teeth.
Yeah.
What?
Isn't that just the Leviathan?
A mile long?
Naga gods?
Some random little town in Massachusetts?
It's just a Leviathan, bro.
Nothing to be scared of.
What?
Oh, that's from the One Piece live action!
What kind of a footage-
Where are you getting all this footage from?
Oarfish?
Ew.
Eww!
They rise to the surface to feed on what?
Okay, it bothers me that you didn't say on what.
It's the Leviathan!
Oh my god, bro.
Oh my god.
All right.
Talk about mermaids now?
What's that?
The Naga?
Okay, stop.
Pause, pause, pause, pause.
This title of the video-
I just want to make sure.
It's mythical creatures that really existed, right?
It really did exist.
The Naga existed.
This dude right here?
We're talking about this guy?
What?
Those are two very different descriptions of one creature.
It was a human with a snake body or a snake with five heads?
How are they even comparable?
I'm so stressed out right now, guys.
I'm so stressed out.
That's a very specific reason to worship a god.
To not be bitten by a snake.
Guys, I've been alive for like 72 years.
And I've never even been-
Gotten-
Came close to being bitten by a snake.
Only guy that I could imagine would be getting bitten by snakes on a regular basis
is this dude, Terra Green.
Because, I mean, let's face it.
He's asking for it.
...than with floods, drought, or sickness.
Snake worship still exists today in some parts of India.
The cobra is especially important in this-
Oh, the cobra is so cool.
During the Naga and Nami festival, people offer milk to snakes,
following an old custom based on legend.
Many times-
Really?
They still show carvings of Nagas with their hoods raised
as symbols of this ancient practice.
Some historians believe this legend began
when ancient tribes saw snakes living near rivers and streams.
Okay.
So they imagined Nagas as guardians of water and land.
Over time, this belief became part of rituals.
Even today, Naga stories are everywhere.
From temple art to modern TV shows like Nagin,
where the Naga is shown as a mysterious, shape-shifting being.
I gotta love the Bollywood level production, guys.
Oh, you gotta love that.
That was perfect.
Oh, that was perfect.
Some say these are just old stories, but others wonder,
was it based on something real?
Either way, the legend of the Naga still wraps around our imagination.
Wraps around our imagination?
Did you guys even-
Bro, you're seeing-
You're hearing, but you're not listening though.
Could snake be wrapping around stuff?
Come on, bro.
My man's spitting bars.
Number six.
That's Japanese.
A shadow from Japanese legend.
A sea monk feared not for its roar, but for its silence.
Stop.
The sea goes still.
No wind, no waves, nothing.
It feels peaceful, but that's exactly when you should worry.
Without warning, boom.
A towering wall of water rises from nowhere.
Ships vanish in an instant.
But the real horror comes after.
Oh, god.
This figure, it quietly asks for a bucket.
Simple, right?
But handed a regular bucket, it begins filling your ship.
Calmly, steadily, until you sink beneath the waves.
Almost like it enjoys watching your panic.
There's only one way to escape.
So you're giving it-
You're literally handing it your own death.
Yo, the umibozu is kind of a piece-
Bros, asking for a bucket just to fill your ship up with water?
That's messed up.
Watching your panic.
There's only one way to escape.
Tricky.
What?
Give it a bucket without a bottom, and you might buy enough time to get away.
What does umibozu look like?
What?
Dude, it's so big.
How are you gonna get away?
Oh, that's so creepy.
Legends disagree.
Sometimes he's massive.
Taller than sails.
Sometimes as huge as a mountain.
Rising faceless from the deep.
Other times he stretches snake-
Oh, god.
Some tales even describe smaller versions that attack in groups.
Like evil mermaids hunting together.
No matter what form he takes, one thing stays the same.
His arrival means danger.
Today, umibozu haunts anime, movies, comics, and video games.
Okay, so we're safe, guys.
Only the weebs are in danger.
We're gonna be perfectly fi-
Oh, no. I'm a weeb.
Oh, god.
That's not good.
So I've been studying Japanese a little bit, guys, since I've been living out here.
And if you're a weeb like me, then you might also know umi means the ocean.
And bozu, I'm pretty sure, means a monk.
So maybe this thing is just mad because it's bald.
Science says he's just a story.
But when the sea goes quiet and fog swallows the horizon,
Japanese sailors remember one thing.
Silence is a warning.
No, dude.
Number five, Moby Dick.
Moby Dick might seem like just a story.
Oh, I know Moby-
But it's rooted in grim reality.
On November 20th, 1820, the American sailing ship Essex was sailing the Pacific
when a massive sperm whale rammed it with-
I shouldn't laugh at his name because it could probably swallow like a thousand of me whole.
But a whale would just never not be funny.
The ship sank, leaving 20 crewmen adrift in small boats.
Hunger and thirst set in quickly.
Weeks passed, and their journey turned into horror.
In the end, only five made it back alive.
After being stranded for 89 days, driven-
89 days?
Did they eat each other, bro?
How do you-
How do you go 89 days in the middle of the ocean?
Therefore, while Herman Melville's Moby Dick is fiction, it's no wild fantasy.
Melville drew heavily from real stories of 19th century whalers.
Sailors back then didn't just hunt whales.
Oh, God.
Sometimes whales fought back.
Whales were being slaughtered for oil.
But these giants weren't-
For oil?
Sailors told tales-
They got oil in them?
Really?
Of furious whales that attacked ships without warning,
overturning them or dragging them beneath the waves.
High key, bro.
If you're killing, like, thousands of whales just to get oil out of them,
you kind of deserve that, you know, that sweet, sweet revenge from the whales.
One tale especially captured Melville's imagination.
The legend of an enormous albino whale.
Pale as a ghost, stalking the Pacific.
Whoa.
Sailors swore it was violent.
A ghost whale?
Attacking ships with terrifying precision.
This beast earned a chilling reputation as-
Any second now, bro's gonna put up a clip of-
Of, uh, of Laboon from One Piece.
Okay, also something really funny about a whale named Moby Dick.
Like, sometimes jokes just write themselves, you know?
You don't really even have to add anything to it.
What's next?
Ogopogo?
The Loch Ness Monster?
Where is it?
British Columbia!
That's Canada!
That's where I'm from!
No, bro!
They got Canada too?
I thought Canada was supposed to be safe.
Something is down there.
Sitting on a beach on a sunny day, you don't expect to see a dinosaur come out of the water.
A dinosaur?
Ogopogo, Canada's very own Loch Ness Monster.
Ogopogo is described as a dark green black serpent.
Dark green black serpent?
You just described, like, three different colors.
With a thick scaly body-
15 to 25 meters.
And a flexible neck.
It moves in smooth undulating humps.
Powered by a strong tail and fins.
What?
Often leaving a foamy wake as it zips across the lake.
The first official sighting was in 1926-
When a group claimed they saw a strange shape moving through the water.
Since then, blurry photos, shaky videos, and stories have kept the legend alive.
In the 1980s, a $1 million reward was offered for proof.
Greenpeace-
By who?
Who's offering up a million dollars for this?
Man, I'm about to go out there and find it myself.
Greenpeace even argued Ogopogo should be protected like an endangered species.
What's clear is that Ogopogo became a tourism magnet.
Kelowna even put up a playful cartoon statue.
This is not a joke.
Why would you put that up?
It's not funny.
It's not cute.
It may be a prehistoric relic.
Scientists dismiss it as waves, light tricks, floating logs.
But here's the thing.
No one can prove it exists.
But no one can prove it doesn't.
Every ripple and strange shape-
Okay, but that's the stupidest argument-
That's the dumbest argument I've ever heard.
You can't-
Technically, you can't prove that the One Piece doesn't exist either, right?
Are we gonna go out looking for the One Piece now?
Beneath that glassy surface keeps the mystery alive.
Maybe one day, someone will capture undeniable proof.
Until then, Ogopogo stays right-
What is that?
That looks like a pile of garbage.
Number three, Cthulhu.
Cthulhu is a creepy sea monster from a 1928 horror story
said to haunt dreams from the depths of the ocean.
But long before that tale, real sea monsters ruled the deep.
One was Tusotoothus, a massive-
Tusotoothus?
I never even heard of that.
Two giraffes laid into it.
It had a hard shell inside, which made it stronger and faster than modern squids.
And to be clear, those are all different from the Kraken.
We got Cthulhu, Tusotoothus, and the Kraken now?
The Earth is not safe.
We have to leave.
Guys, we have to evacuate ASAP.
Giant fish, and even baby marine reptiles.
But like many others, it disappeared when the asteroid hit 66 million years ago.
Oh, thank God.
Okay, they're dead.
Guys, they're dead.
Tusotoothus was real.
And here's something to think about.
We've explored only 5% of the ocean.
So if monsters like that-
You don't have-
You didn't have to mention that again.
Number two, Nixie.
Nixie?
What?
Oh, I was just about to say, you know what?
Like, Nixie might be kind of bad.
This ruined it completely.
Nixie, what are you doing out here?
What are you doing?
Guys, I can save her.
Ew.
That's the poison ivy.
What?
That's kind of hot, isn't it?
Oh, I've heard of-
I've heard of water sprites.
What?
Well, mermaids are from like the ocean, right?
But these-
These Nixies are from the dirty, disgusting swamp.
Big difference.
Ocean.
Beautiful.
Scary.
Swamp.
Disgusting.
Also kind of scary.
Sailors of what?
The swamp?
Oh no.
Okay.
That's sweet.
Ew.
Disgustingly ugly to the women you have seen in your life must be
for you to mistaken this for a woman, bro.
That's crazy.
What is this?
The hell even is this?
What?
Uh-huh.
Oh, ew, ew, ew, ew, ew, ew.
Okay.
That looked way too real.
El Gran Maja?
Dude, I swear I've seen this thumbnail in like Roblox fish videos before.
Am I crazy?
Oh, hold on.
Give me a second.
Look, look at this.
Sea monsters on Roblox.
There it is.
El Gran Maja.
Oh, there's one right there.
Almost every single thumbnail is of the El-
Is like a different iteration of the El Gran Maja.
That's actually crazy.
Okay, let's continue.
Arctic ocean.
Oh my God.
No.
What?
Bro, I'm actually so scared.
Excuse me?
Yeah, no, if these things live on the same planet as me,
I don't want to be here anymore, bro.
Elon Musk, get me to Mars.
Oh my God.
Look at it.
Okay.
No.
No, the clip.
Oh my God.
Okay.
First of all, you're kind of down for going in the first place, right?
Like who doesn't know the ocean is scary?
Second of all, yeah, no.
This thing definitely exists somewhere on the ocean.
Again, 95 unexplored.
That thing is real.
100%.
Yes.
100% real, bro.
Just like aliens.
We got to find it.
Is there a drop in the ocean?
There's more?
There's a...
Oh, what?
Well, guys, I guess comment down below if you want to see part two.
Subscribe if you're down there, but I need a break for now.
See you in the next one.
