Congrats, man.

The only catch is I'm going to do everything in my power to destroy it.

And it's up to you to protect it from attacks like 100 cannonballs,

massive explosives, and so much more.

You got to be kidding me.

And you have exactly 24 hours from now to build your defenses for the yacht.

Time has started.

Good luck.

All right, dude.

Let's see if this yacht sinks.

Sean, using my credit card,

immediately bought a bunch of supplies

and began building his defense against phase one, 100 cannon shots.

Run me through your plan.

My plan is to build a giant wall angled to hopefully block the cannon fire.

And after working all throughout the night,

into the next morning and all the way through a complete

24 hours, Sean was going to have to call it.

Because the time is up.

Let's go shoot some cannons.

Will his defense protect his new yacht

from a hundred cannonballs

or will we start this video over with a new contestant?

Phase one of four has begun.

- I'm nervous. - All right, Sean.

We're about to fire the cannons at your new yacht.

- Terrifying. - Aim the cannon.

Fire.

That's just going right through.

Dude, it is ripping through those storage containers.

The cannons were melting through his defense like butter.

I'm toast, man.

I feel like I lost a little piece of my soul.

And probably a piece of your yacht.

The cannons were already damaging Sean's yacht,

and we're just getting started.

These cannons are tearing me up. She's a goner.

I guarantee it just went straight through.

We kept firing cannon after cannon ripping through Sean's defense.

These cannons were way more hardcore than I thought they were.

After a torturous three hours.

Oh, go, go, go.

Let's go see this thing.

Somehow.

God, I hope my yacht isn't shredded.

Sean's yacht actually survived.

You have a tiny hole and it hit a rail.

Dude.

Bro, a cannonball hit right here.

But that was only the least of the damage.

No.

The bathroom in Sean's yacht was completely destroyed.

Look at that mirror right there.

Three cannonballs hit your yacht and you nearly survived phase one.

I'll take it. Three out of a hundred. It's pretty good.

No, I need you to take phase two more seriously.

Ok.

And if you don't think I'm being serious, I'll just show you.

Bring out the bomb.

In 24 hours.

Those 15 sea bombs will explode around your yacht.

Oh, no.

And by the way, we tested these things before the video.

They are extremely powerful.

15 big booms in a circle around this thing.

How am I going to protect this?

I'm gonna go hit the hay in a yacht surrounded by bombs.

Come back fresh in a couple of hours.

Sean got up the next morning and immediately got to work,

but because of the severe thunderstorm, he couldn't use his crane.

This is brutal.

We're doing everything today by hand.

How are you going to pad up the yacht?

Mattresses.

That's right.

Sean's big plan is mattresses

and his workers bought every mattress in town.

All of those mattresses.

We'll start ferrying them back and forth.

There we go.

All the way around, every inch.

I can't even tell this is a yacht anymore.

It just looks like a bunch of mattresses.

In 2 hours, we blew up the mines and he hasn't really done

as much as I thought.

These are heavy.

You know how much easier this would be with the crane?

You know how much easier this would be if it wasn't in water?

Yes.

Clock's ticking.

This is not looking good.

I don't think his yacht's going to survive.

Three, two, one.

Time's up.

That's all I'm going to get.

So he has some mattresses and water jugs.

Karl, can you cover his ears?

This might be the most hideous thing I've ever seen.

What I'm getting from you is you don't think this is going to work?

- Yeah. - Yeah?

Yeah.

Let's see if the yacht sinks.

Any last words?

Can I have the hat?

I will give you my hat if your yacht survives.

All right.

Three, two, one.

Blow it up.

No!

Oh my gosh.

- There's no way that didn't do damage. - It is over.

- Come on. - Let's go check it out.

My yacht.

It looks good.

She's still standing.

You did it.

It just burned the mattresses. That's right.

I'm not sure what to say.

Somehow, these mattresses were actually

a very effective defense against the mines.

In front of us is phase three.

This attack consist of three different levels.

We're going to be launching a million fireworks

straight at your yacht,

followed by a barrage of flaming arrows, a level higher

and finally catapults launching flaming death balls from the sky.

And by now, Sean's build strategies were getting pretty efficient.

He gave his crew orders.

Yeah, let's go ahead and get those

containers moved into place for phase three.

Then got some much needed rest while they worked.

Now it's on to trebuchets, fireworks and flaming arrows.

What is your plan?

My plan is to basically get more shipping containers and build a giant wall.

And I'm basically just hoping that that wall will be

tall enough to block the fireworks and the flaming catapult debris

from hitting the yacht.

That's so sketch this whole thing is so sketch.

Today is my day. I'm feeling it.

I'm hard...

- Hard confidence now. - Okay.

Compared to phase two.

This is insane.

- You really stepped it up. - Yeah, man.

You went from a pathetic build that led multiple cannonballs through

to this, which I actually think might work.

He is currently taking lake water, flushing it through sprinklers

to wet his mattresses.

All right, We're about to go inspect his defenses.

Is now a bad time to tell you guys, I'm afraid of heights?

This is a 40 foot tall, solid wall.

When we fling the catapults,

they're going to fly over the shipping containers where I'm at

and hopefully hit his yacht.

Right?

No, you're going to miss.

Hey, Chandler

envision you're catapult with giant flaming balls.

I got you.

Ready?

Aim,

Fire.

That's the one.

Dead hit.

Your boat's going down.

Not going to happen.

All right, So why are you so confident?

You have 30 seconds where you can be building and you're doing nothing.

We're ready. It's covered up. I built the wall.

Everything's wet back there.

Do we even need to wait 20 seconds?

No, let it rip.

Let's do it.

Time's up. Phase three is upon us.

Catapults, flaming arrows and a million fireworks.

Let's see if this yacht lights on fire.

Ready the fireworks.

Any last words?

Good luck.

Fire the fireworks.

Oh, my God.

That doesn't look real, bro.

That is wild.

Oh my gosh.

How is this… How is this doing that?

While these pretty fireworks are going off,

I'm going to tell you about Bloons Tower Defense 6.

Bloons Tower Defense is a game

I've actually been playing since I was a teenager.

- Oh my god! - They're so many.

No joke.

I used to literally play this in English class when I was 15.

Dude, I see smoke on his yacht.

And they're back with their sixth installment of the game.

Bloons Tower Defense 6.

Oh, my God.

How is this doing that?

And if you've never played Bloons Tower Defense,

basically you defend yourself against the balloons

by placing monkey towers and heroes on the map.

- I want to celebrate something right now. - Oh my goodness, bro.

It's hitting his yacht.

Oh, yeah. It is hitting the top of his yacht.

That firework just hit his yacht.

Blow up the arrows.

Now, it's time for a thousand flaming arrows.

Oh my God.

The arrows are going right over his wall.

- Wow. - Yeah!

I wouldn't cheer yet.

Ready to catapults.

Ready?

And because of the sponsor, the next thing we're flinging are balloons...

...on fire.

Here we go.

Basically, flaming bowling balls.

Fire in the hole.

There goes.

That's going straight for his yacht.

They hit the shipping container right by his yacht.

Let's go, baby.

If you buy anything in-game, use MrBeast

in the supporter creator code, if you want to support me

and help me do more videos like this.

Make sure you download Bloons Tower Defense 6.

And if you download it right now, you can get a MrBeast pack for free.

Oh my God!

Dude, his boat is exposed.

Sean, I'm feeling worried for you right now, bro.

I'm still feeling good. I think I'm good.

This is a heavy balloon.

Dude, this looks nothing like a balloon.

You just don't look good enough balloons.

The defenses are falling

Let it rip.

And if just one of these catapult shots lands on Sean's yacht,

This whole video might be over.

That was a little closer than I thought it was going to be.

Fire the final catapult.

Oh, that's a direct hit.

Water.

The only thing burned today is me, boys.

All right. You know what?

Sean, you might be laughing now,

but you are not ready for this final phase.

In 24 hours from now, we will be attacking your yacht

with a barrage of machine guns.

Any questions about phase four?

In addition to every single phase so far in this video combined

the fireworks, the catapults, the arrows, the 100 cannons.

You have 100 more cannonballs?

And rather than a bunch of bombs,

this giant monstrosity, borderline nuclear missile,

questionably even illegal, island flattening sea mine.

All of that on top of machine guns?

Yeah.

Today is phase four of the challenge.

The general plan is to just put

a ton of stuff between my yacht and the up and coming attacks.

We're going to use the remaining crates

to try to block any cracks the bullets might get through.

That container is just perfectly placed for this outside purge.
