It's too cold for pirates.

But not for my cousins, the Adélie penguins. I can't wait for you to meet them.

Aye, me hearty. Why couldn't we meet them somewhere warmer?

Adélie penguins don't live anywhere else in the world. Antarctica is their only home.

We've come to visit at the perfect time. The chicks have just hatched.

And Quasi, Peso and I are going to give their parents a little help.

Yeah, what kind of help?

Babysitting, of course.

Babysitting?

Quasi, Peso, to the guppies.

Hi, Peso.

Thanks for keeping an eye on the chicks while we swim out into the ocean for food.

Mum, Dad, can I come too? I'm not too scared to swim in the ocean.

You're still a chick. You haven't grown your seagoing feathers yet.

Yeah, Rocco. Grown-up penguins have special feathers that keep us warm in the freezing water.

You'll get too cold swimming in the ocean. It could make you sick.

Bye, Rocco. We'll be back soon.

Keep an extra eye on my Rocco. He's a daredevil. Completely fearless.

Don't worry. I know the type.

So, what's in the box?

Presents for everyone!

A rock!

A rock. That's right.

Adelie penguins collect little rocks to build their nests. See?

Line up, everyone, and we'll pass them round.

My name is Flip, and I'm a penguin.

My name is Flip, and I'm that.

Here's a present for you.

And one for you.

Your little rock is better than my little rock.

That's a tough one.

Well, let's see.

Here we go. These two rocks are exactly the same.

Thank you.

Good work, Pezo.

Captain, there's an iceberg on the moon, and it's heading for the octopod.

I'm on my way.

Pezo, Quazi, you'll have to handle the babysitting without me.

I'll miss all the excitement.

Not all the excitement.

I'll babysit most of the chicks, and you babysit Rocco.

Just Rocco? I can do that with one poor tide behind my back.

Flip! Flap!

Come away from that ledge.

Well, it looks like it's just you and me.

So, what... Rocco?

Where'd he go?

Rocco!

Quazi!

Cannonball!

That's what my mum always says.

Let's mop rocks.

Let's mop rocks.

I want my old rock back.

Why?

Because it's better.

I'm sure the rocks that I gave you were exactly the same.

No, my old rock had a brown spot on it, and this one doesn't.

Let's swap back.

No.

I'm sure we can work this out.

Now, Flip.

Oh, Flap! Hey, Flip.

Oh, sorry, Flap.

You mean Flip.

Yes, Floop. I mean, Fleep.

I mean, oh, Flappity Flippers.

Flap, if you flip over your rock, you'll see it has a brown spot just like Flap's.

I mean, Flip's.

You're right.

Flappy now. I mean, Happy now.

Happy!

Phew!

See that bird up there?

Aye, matey.

I like to play a little game with him.

Watch this.

Hey there, you big beaky birdie!

You don't scare me!

See? Now he's coming to get me.

Shiver, whiskers.

He is coming to get you.

That was fun.

That was close.

Rocco, me hearty, you have to be a little more careful.

Even in my pirate days, I never...

Where'd he go?

Rocco?

Quazzy?

Cannonball!

Whoa!

I think Captain Barnacles has the easy job today.

This water is getting rough.

Dashie to Captain Barnacles.

There's a storm about to hit and it's big.

The iceberg has changed direction.

It's heading towards...

Me!

Dashie!

Sailing!

Octolabels!

Octolabs to the HQ.

Octolabs, there's a big storm on the way.

That's dangerous for the Adelie penguin parents.

They could get lost at sea.

The storm will blow ice and snow onto the shore.

Peso and Quazzy will need to find a way to keep the chicks warm.

Dashie, contact Peso and tell him to get ready for ice and snow.

Ready on it, Captain.

I'll find and rescue the Adelie penguin parents, but I'll need a bigger gup.

Tweak, meet me outside the octopod with the gup sea.

Got it, Cap.

Octonauts, let's do this.

Hang on, penguins. I'm coming to get you.

Got you.

Two more.

Hold tight.

Hop on board.

We're through it.

We need a shelter to keep the chicks warm.

And we need it fast.

Bandages.

Bandages?

Quazzy, throw me bandage rolls as fast as you can.

Ready?

Aye, but...

Go!

That should do.

It's perfect, me hearty.

Everyone, inside the tent.

This is so exciting.

I don't want to go inside and miss the big storm.

Rocco, it's too cold for you out here, matey.

Oh, all right.

That ought to do it.

Nice and cosy.

Right, Rocco?

Where's Rocco?

If he's not in here, then he's out there.

I'm going after him.

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Rocco!

Quazzy!

Rocco!

I'm too cold to move.

Hold on, matey.

I'm coming for you.

Quazzy!

Whoa!

Cannonball!

Now that was close.

Let's get inside that tent and warm up.

All right, Quazzy.

We'd all be icicles if it weren't for this tent, Peso.

I hope Mum and Dad are all right.

How will they make it back in this storm?

Don't worry.

Captain Barnacles will bring them home.

And nothing can stop the captain, matey.

An iceberg on the beach could really slow him down.

Not that iceberg again.

How will we get home, Captain?

Don't worry.

The Gulf Sea was built to break through ice.

Penguins, this could get bumpy.

Yay!

I told you the captain would bring your parents home, matey.

Mum! Dad!

Octonauts, thank you so much for...

Hold on.

Where's Rocco?

Where's Quazzy?

Just one more time, eh, matey?

Cannonball!

Grrr.

Captain Barnacles, come in.

Dashie, what is it?

Something's not right.

I'm getting a strange weather warning.

Meet me in HQ.

Aye, aye, Captain.

It's the biggest whirlpool I've ever seen, and it's heading straight for us.

We'll be sucked right in.

Dashie, prepare to move the Octopod to calmer waters.

Attention, Octonauts.

There is a giant whirlpool heading for the Octopod.

Please put away any items that could fall or be broken.

Activate launch now.

What's that, Tunip?

You found some strange objects in the garden pod?

Well, let's go.

Jumping jellyfish.

They're eggs, but who or what laid them here?

What's tickling me toes?

Avast, ye toe tickler!

Come out wherever you are!

Ha-ha-ha-ha-ha!

Ha!

Ha-ha-ha!

Meow!

Hmm.

Oh.

Oh.

Ah-ha!

Oh.

Huh?

Hmm.

Ah!

Snake! Snake on the Octopod!

Some penguins are so uptight.

Octonauts, to the HQ!

Huh?

Octonauts? What's going on?

There's something aboard the ship.

We found eggs in the garden pod. I saw it in the library.

I almost captured it.

It was a snake.

A snake? On the Octopod? Are you sure, Peso?

Yes. It was in my medical bag.

It must have been a sea snake. Many kinds of snakes live underwater.

Was it one of these, Peso?

No. No. That's the worst.

A sea krait.

They're the only sea snakes who lay their eggs on land and not in the ocean.

Those must have been sea krait eggs that we found in the garden pod.

But how did one get on board?

I'll check the security cameras.

There!

Ah-ha! So she snuck in in the middle of the night.

And now she's trying to get out.

Once sea kraits lay their eggs on land, they immediately return to the water.

She can't swim out now. She'll get sucked right into that whirlpool.

Octonauts, find the sea krait and keep her on board until it's safe.

Um, there's just one other little thing, Captain.

Sea kraits are poisonous.

Poisonous?

Yes. But she'll only bite if she's scared.

We'll have to be very, very gentle with her.

These handy snake grips?

We'll have to be very, very gentle with her.

These handy snake grippers ought to do the trick.

Octonauts, let's find that snake.

That whirlpool is stronger than we thought.

Dashie, activate steering wheel.

Aye-aye, Captain.

Whoa!

Ah!

Sounds like a snake.

Aha! Gotcha!

Oh.

Aha! Prepare to be rescued, sea krait!

No!

Stop right there!

I am so getting off this ship.

Follow that snake!

This must lead to the sea.

Oh, no, you don't.

Captain, the snake is escaping through the land vent.

Let me see if I can help.

I need to get into the sea.

Why are you trying to stop me?

We're just trying to help.

There's a dangerous whirlpool out there.

If you go out now, you'll get sucked right in.

Seriously?

We're so serious.

So can we bring you back to your eggs until the whirlpool passes?

That's not how it usually works, Penguin, but sure.

They hatched! That's great.
