Can you believe these emperor penguins have been standing out here since the winter started in Antarctica?

It's true.

It's up to these penguin dads to keep their eggs warm until they hatch.

The penguin mums are at the ocean getting food for their family, but it's a long, long trip home.

I hope they're back soon.

Yeah, me too.

It's going to turn right boring just standing here.

We may be bored, hungry, and tired, but we're emperor penguins.

We'll do whatever it takes to keep our eggs safe.

Right, dads?

Right.

I can hear you.

Right.

Shellington to Gup Eye.

Not quick here.

The emperor penguin eggs are fine and the fathers are staying strong.

Very good, Shellington.

It looks like the temperature is warming up.

The rain is nearly here.

The winds are calm and...

Huh?

What's that noise?

Follow me.

Quick, quick.

Ah!

Penguin chicks.

They're scratching because they're hatching.

Super, super.

Let's go and tell Captain Barnacles our egg-citing news.

Cracking.

Good to hear, Shellington.

The emperor chicks have hatched, and that means it's time to go home.

We'll be back.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

Bye.

It's almost time for the mums to head back home.

How are the emperor penguin mothers doing, Peyso?

Swimmingly, Captain.

Look!

They're chasing after food so they can fill up their tummies and feed their families.

Incredible.

Look at that strength and speed.

My emperor penguin cousins are champion divers.

They can swim deeper than any other bird.

Dashie, Kwazi, it's almost time for the penguin mums to head home.

How's the research coming?

Amazing, Captain.

I'm getting some video of emperor penguins feeding that nobody's ever seen before.

Look at them go!

They're flipping and zipping.

And now I'm getting some video of Kwazi that nobody's ever seen before.

Oh, I am so sorry.

Are you alright?

Yeah, ready to go again.

I'm still new at all this.

First year laying an egg, first time diving for food as a mum?

First time?

You swim like a pro.

Oh, you think so?

I feel so full and clumsy.

It's our last meal before the long trip home, so we have to eat a lot.

Oh, excuse me.

It looks like the mother penguins have finished eating and are ready to get back to their families.

We'll want to be on the ice when those penguins surface.

It tells me it's going to be quite a show.

Look!

Did you see that?

Those penguins launch faster than cannonballs.

Check, check.

Check, check, check.

Barnacles to gup eye, the emperor penguin mothers are on their way back home.

Not all the mothers, we're missing one.

Where's the penguin that gave me a ride?

She must still be underwater.

She'd never be late on purpose.

Penguin mothers know when it's time to go back home.

See?

Something must have happened to her.

She may need help.

Dashie, take the gup S under now.

Captain, emperor penguins can only hold their breath for 20 minutes.

Then we'd better move fast.

There, captain.

Peso, let's bring her aboard.

Easy does it.

This penguin's a lot heavier than you, Peso.

She's an emperor penguin, the biggest, tallest penguin there is.

And it looks like she's broken a foot and sprained a flipper.

What happened out there?

I remember swimming to the surface, but then I hit a chunk of ice.

This thing I remember.

You saved me.

Now I need to get home.

You need to rest.

But my family is waiting for me.

Then they won't have to wait long.

We'll bring you back to the nesting ground ourselves.

Oh, thank you.

The wind's picked up.

I think a blizzard's headed our way, captain.

Any sign of the other penguin mothers yet?

I can't see much in this weather.

Everyone, into your snowsuits, just to be safe.

Way ahead of you, captain.

Barnacles to gup eye.

Can you find us a path away from this wind and snow?

Turn north-west past the nearest ice peak.

You'll be sheltered there.

Understood. Thanks, Knackquick.

Feels like we're picking up speed.

You'll be home to your family soon.

Oh!

I seem to be bumping into a lot of penguins today.

What's happening?

The ice underneath us is cracking.

Ice chasm!

Octonauts, abandon the gup test now!

Oh, no!

Captain!

Never a dull moment in the Antarctic.

You had us worried, captain.

I'm all right.

But I can't say the same for the gup S.

Better sound the octo-alert.

Octonauts, to your stations.

That's odd. For a second, I thought I heard the octo-alert.

Huh?

My octo-compass is frozen and the octo-alert isn't working.

Gup eye, come in.

Come in, gup eye.

Shiver me whiskers.

And all me other parts, too.

We can't stay out in the cold like this.

Don't worry. We'll keep warm by carrying you home.

But which way is home?

Um...

I have no idea.

And the map's not working.

Bad way is home.

Huh?

That's right.

Emperor penguins can find the way back to their babies without a map or a compass.

Even in a blizzard.

Octonauts, let's do this.
