[theme music]
[birds squawking]
[heroic music]
Zane, would you do the honors?
[beeps]
[all gasping]
How did you build this so fast?
I had been tinkering with it in my spare time
over the past several years.
It's amazing, Pixal!
I am proud to say it is one
of the most sophisticated vessels
I have designed and is practically unsinkable.
You know what happens
when you call a vessel "unsinkable," right?
It doesn't sink, of course.
[grunting]
This is great, Pixal. Just what we need.
But how sure are you that the underwater pulse
you guys saw is causing my powers to freak out?
-[tranquil music] -97 percent positive.
That's pretty positive.
But what if my powers go crazy on me while we're down there?
Maybe I should sit this mission out.
That's exactly why we need you to go.
You're the Master of Water!
There's no one more connected to the sea than you.
[Master Wu] However, you do make a point.
If you'd rather stay here, with your mother--
[Nya] No, no, no. Jay's right. I'll go pack!
[laughs]
[Nya] I don't know how long we'll be gone.
However long it takes to figure out
what's creating this pulse and shut it down.
Sounds like it'll be dangerous.
So I guess I'll have no one to play "Prime Empire" with.
Hmm.
Wait, I'm not going on the mission!
Wu wants to study the current and previous Masters of Fire.
That's your and me, pops. [clicks tongue]
And besides, if that pulse hits again,
someone has to protect Ninjago City.
Cole is staying too.
[video game music playing]
Does Cole play "Prime Empire"?
Not as well as I do!
[scoffs] In your dreams, Kai.
[somber music]
Are you sure this is the right time
to be going on a mission?
Mom, I go on missions all the time.
Missions are pretty much the main thing I do.
Don't you think it's time to maybe take a break?
Rest a little.
Maybe that's how you used to solve problems,
but the way I do it is to get involved and fix things.
[club dance music]
[grunts]
[yells]
[sighs] Jay!
[clears throat] Sorry!
[birds squawking]
[spooky music]
All hands ahoy, ye old salts!
Cast off! And be quick about it!
Why are you talking like that, Zane?
Let me guess.
You downloaded thousands of terabytes of movies
and novels on sailors
and pirates in order to prepare for our journey.
Yargh! And musical sea shanties.
Now stow that jibber-jabber and cast off, I say! Cast off!
[exhales sharply]
That's better!
Now full ahead, and sound off, the lot of ye!
Navigation is go.
Engines are go.
Sonar is go.
Uh... sorry, what am I?
Blast me wits! You're at the helm, lad, the helm!
Oh! [clears throat]
Helm is go!
Music to me ears! Dive the boat.
Make your depth 300 feet, and full ahead!
[epic music]
[beeping]
Hm. I'm detecting movement in the aft corridor.
Fie! How can that be? We're all here.
Never mind. Must be a faulty sensor.
[eerie music]
[Pixal] We are entering open ocean.
Avast, scallywags, we must be on arrrrr guard as we dip inta
the dark and briny deep and fathoms unseen!
Yeah... I'm gonna need
a "Pirate to Nindroid" translation on that.
What Zane means is that we are now traveling
to the deepest part of the ocean,
a trench known as the Tartarus Trench,
which has never been mapped...
so we should prepare for the unexpected.
[melancholic music]
[Jay] Ah! Delicious!
[moans]
At least this quest means lots of fresh sushi.
You sure you're not hungry?
Jay, the ocean's good for much more than food.
As we go deeper, I can feel its elemental power growing...
it's almost overwhelming...
Don't worry, Nya.
Whatever is freaking out your powers,
I know we'll find the solution down here.
No one's ever been this deep before.
We have no idea what we'll find down here.
Well, [laughs] one thing I don't want
to find is myself in the pirate brig.
I'm sure Captain Zane would have us keel-hauled
if we don't do our dishes. [gasps]
[playful music]
[Lloyd] What?
Who made my bed?
Is that... [sniffing]
Pillow mint?
Ahh, the most refreshing mint of them all. But how?
Did someone already wash my clothes?
[quirky music]
[Nya] Zane, we might have a problem!
[Lloyd] Yeah, the chores are--
Wait, why are you walking like that?
I be simulating the walk of a pirate with a peg leg.
Sure. Okay. One question. Why?
So me crew will respect me, of course, ye briny barnacles!
[Jay panting] Guys!
Guys! Someone's been doing all my chores!
[dramatic music] There's only one explanation.
Right, a stowaway.
What? No!
We're being haunted by the ghost of some butler!
Probably named Ducklesworth or something.
[gasps] It's Ducklesworth! Get him!
Where'd they go?
Hello, he's a ghost!
He can fade through walls.
Ghosts are like super Ninjas.
Wait. Let's say I was a Ninja.
A former Ninja. Where would I...
[gaps] I knew it!
Oh, hi, sweetie. You're here too? [giggles]
[Jay] You're Ducklesworth?!
[Nya] There's no ghost butler, Jay.
Just my mom not believing I can do anything on my own!
That's not true, Nya.
I just wanted to be there for you,
to help you figure this out...
Besides, you're the one who told me
it's important to get involved and fix things. So I'm here!
We're turning around and taking you home!
Stand fast!
We be miles 'neath the briny blue.
We canna turn back now!
Oh, see? No back-sies.
Don't worry, I'll bake us some muffins!
[Lloyd and Jay] Yes!
[chuckling]
[Pixal] All crew to the bridge.
We are now approaching the Tartarus Trench.
[suspenseful music]
Ah. Maya. Good to see you.
That explains why my clothes were pressed and folded.
Oh, that reminds me, Jay, honey,
I need to teach you how to bleach your boxer shorts.
Oh, come on.
Pixal, what are those structures approaching?
Spires of rock.
Reduce speed.
[crashes]
[all] Ah!
[beeping] No damage detected.
[all exhales]
[suspenseful music continues]
Look...
[Nya] It's like a graveyard of ships.
[whimpers] What do you suppose happened to them?
Hold fast, lads. Keep your nerve.
-[alarm beeping] -What was that?
[explodes]
We're taking fire!
Something is approaching fast.
[beeping]
Avast! They've hit us abroadsides!
Evasive action! Return fire!
Locked on target.
All stun torpedoes.
Chutes one and two! Fire!
[explodes]
I've lost the target.
[Jay] Did we hit it? Whoa!
[alarm ringing]
[Pixal] We've lost power!
[beeping]
[Nya] We're sinking!
We are approaching maximum safe depth!
We must stop our descent!
[Nya] I see a ledge of some kind to our left!
Left full rudder! Brace for impact!
[tense music]
[all grunting]
[steam hissing]
[all screaming]
[thuds]
I'm definitely going to need to wash my boxer shorts again.
[laughs]
[shushes] No one make a sound!
They can still hear us.
[Lloyd] Is everyone okay?
I think so.
[Zane] I be alive.
[Pixal] I do not believe it can see us.
Great!
Now how do we get out of here?
[sighs]
It appears we have sustained critical damage.
All systems are down.
Shiver me timbers!
We be stranded at the bottom of the sea!
Our unsinkable vessel be sunk!
[tense music continues]
