0:00:02 > 0:00:05- SIREN WAILS - 'Octonauts, to your stations!'
0:00:05 > 0:00:07Barnacles!
0:00:07 > 0:00:09Kwazii!
0:00:09 > 0:00:10Peso!
0:00:37 > 0:00:40- Explore!- Rescue!- Protect!
0:00:40 > 0:00:42Octonauts!
0:00:52 > 0:00:56Brr! I can't believe we're back in these chilly waters again.
0:00:56 > 0:00:59- It's all in the name of science, Kwazii.- Indeed.
0:00:59 > 0:01:03Arctic zone creatures make some fascinating sounds.
0:01:03 > 0:01:08And with the Octopod's underwater microphone, we can record them!
0:01:12 > 0:01:14GROWLY GRUMBLING
0:01:14 > 0:01:19- Ooh, what's making that sound? - Oh, heh, just my tummy.
0:01:19 > 0:01:24I ate some of Tunip's kelp cakes with a wee bit too much hot sauce!
0:01:24 > 0:01:28Wait! I'm picking up something else. Listen.
0:01:28 > 0:01:31MOANING AND GROANING
0:01:31 > 0:01:34Sounds like walruses to me.
0:01:34 > 0:01:37The computer will match the sound to the animal
0:01:37 > 0:01:40and we'll see if you're right, captain.
0:01:40 > 0:01:44Ah, walruses! Now let me guess the next one.
0:01:44 > 0:01:46SQUELCHING AND BUBBLING
0:01:46 > 0:01:50'Tis a strange sound from a strange creature.
0:01:50 > 0:01:53And this strange creature could only be the...
0:01:53 > 0:01:56- Herring?!- Yes! Herring.
0:01:56 > 0:02:01They talk by blowing gas bubbles out of their behinds.
0:02:01 > 0:02:03Out of their behinds?!
0:02:03 > 0:02:05LOW HUMMING
0:02:05 > 0:02:07Oh, what's that coming from?
0:02:07 > 0:02:14- Sounds like some kind of whale song. - It is! Bowhead whales.
0:02:14 > 0:02:16They only live here in the Arctic.
0:02:16 > 0:02:20So their sounds can't be recorded anywhere else.
0:02:20 > 0:02:22- WHALE SONG - Look!
0:02:26 > 0:02:32- Howdy, folks!- Hello! We're the Octonauts.- Pleased to meet you.
0:02:32 > 0:02:35That's an enormous head, even for a whale!
0:02:35 > 0:02:38The head of each bowhead whale is as big as a bus.
0:02:38 > 0:02:42We're not aiming to brag now, but we bowheads do have
0:02:42 > 0:02:45the strongest, toughest heads in the Arctic.
0:02:45 > 0:02:50- How tough?- Tough enough to smash through just about anything.- Yiaow!
0:02:50 > 0:02:54And we make some pretty big sounds too. Ready, boys?
0:02:54 > 0:02:56THEY SING
0:03:00 > 0:03:03I'm getting a perfect recording of them.
0:03:03 > 0:03:05Bowhead whales sing all the time.
0:03:05 > 0:03:08While they're travelling, playing, even eating.
0:03:08 > 0:03:10It's how they talk to each other.
0:03:10 > 0:03:14It's nice to make new friends out here on the Arctic range,
0:03:14 > 0:03:16but now we've got to hit the trail.
0:03:16 > 0:03:20It's feeding time. Come on, giddyup, partners!
0:03:20 > 0:03:24- Y'all take care now! - Bye!- Bye!- Goodbye!
0:03:24 > 0:03:26DISTANT SINGING
0:03:29 > 0:03:35- Yaow, what's that?- More whales? - It sounds familiar.
0:03:35 > 0:03:37BLEEPING
0:03:37 > 0:03:41- Narwhals, Captain! - Sounds like a call for help.- It is.
0:03:41 > 0:03:43Then we haven't got a moment to lose.
0:03:43 > 0:03:45Kwazii, Peso, to the launch bay!
0:03:54 > 0:03:58It's coming from inside that ice tunnel.
0:04:03 > 0:04:08Shiver me whiskers, Captain! Look! There's been an avalanche.
0:04:08 > 0:04:12They must be somewhere behind all that ice. Ahoy in there!
0:04:12 > 0:04:16- Narwhals, are you all right? - Help us, please!
0:04:16 > 0:04:20- We are trapped in here, we can't get out!- I know that voice.
0:04:23 > 0:04:30- Boris?- Da! Barnacles? Is this you? - Yes, old friend. What happened?
0:04:30 > 0:04:33Me and my two friends, we dove down very very deep.
0:04:33 > 0:04:35Everything was good, yes?
0:04:35 > 0:04:38Until the pack ice move and trapped us in here.
0:04:38 > 0:04:43The ice, it is too thick for a narwhal to punch through!
0:04:45 > 0:04:50- And we are almost out of air.- Then we need to get you out of there now.
0:04:50 > 0:04:52Octonauts to the HQ!
0:04:55 > 0:04:57SIREN WAILS
0:05:01 > 0:05:04Octonauts, three narwhals are trapped under the ice
0:05:04 > 0:05:06and they're running out of air.
0:05:06 > 0:05:11Jumping jellyfish! Narwhals are whales, and whales breathe air.
0:05:11 > 0:05:14They can only stay underwater for a while,
0:05:14 > 0:05:16then they need to come up to breathe again.
0:05:16 > 0:05:21We'll get them out of the ice, but first, let's get them some air.
0:05:21 > 0:05:23We'll run a breathing tube down there now!
0:05:23 > 0:05:26Octonauts, let's do this!
0:05:31 > 0:05:33THEY CHEER
0:05:40 > 0:05:43TWITTERING
0:05:43 > 0:05:47I've found a small opening for the breathing tube.
0:05:47 > 0:05:50- Here you go.- We're pushing in a breathing tube, Boris.
0:05:50 > 0:05:54- It won't be long now. - Da, please hurry, old friend!
0:05:54 > 0:05:55We are feeling very weak!
0:05:59 > 0:06:04Arrgh! It's caught on something. Ugghh! Urrrgh!
0:06:05 > 0:06:09- Yes! That did it. - Oh! There it is!
0:06:09 > 0:06:13HE BREATHES DEEPLY
0:06:13 > 0:06:17Ah, thank you! Much better.
0:06:17 > 0:06:21Now that you've got air to breathe, it's time to break through the ice.
0:06:21 > 0:06:24Dashi? Let's try the GUP-C's icebreaker.
0:06:26 > 0:06:28Icebreaker activated.
0:06:33 > 0:06:37- Not even a crack. - Let's bring in the drill.
0:06:37 > 0:06:39Tweak, we'll need the GUP-D.
0:06:43 > 0:06:45All right, cap.
0:06:45 > 0:06:49I'll have 'em out faster than you can say bunch of munchy crunch carrots!
0:06:49 > 0:06:53Narwhals, back away as far as you can.
0:06:59 > 0:07:04Oh! The drill's stuck. That ice is just too thick.
0:07:06 > 0:07:08Whoaaaaaaa!
0:07:10 > 0:07:14I'd better pull out! As soon as everything stops spinning...
0:07:20 > 0:07:22Easy does it...
0:07:25 > 0:07:27- RUMBLING - Huh?
0:07:30 > 0:07:33- Ahh!- Oh, no! The breathing tube!
0:07:35 > 0:07:36Oh, it is no use!
0:07:36 > 0:07:40We are back where we started, and we will soon need air again!
0:07:40 > 0:07:44We're not giving up on you, Boris. Octonauts, we tried the GUPs.
0:07:44 > 0:07:48We need something stronger to break through this ice,
0:07:48 > 0:07:50and we need it NOW!
0:07:50 > 0:07:53We could melt the ice with a blowtorch?
0:07:53 > 0:07:56- Good idea, but it would take too long.- Hmmm... Ah!
0:07:56 > 0:07:58HE TWITTERS
0:07:58 > 0:08:00Brrr! Hup-da-whale!
0:08:00 > 0:08:04- How about blasting it with a sonic slicer?- The ice is too thick.
0:08:04 > 0:08:05Hup-da-whale!
0:08:05 > 0:08:08I have an old pirate cannon under me bed.
0:08:08 > 0:08:11- But I'm out of cannonballs. - HUP-DA-WHALE!
0:08:11 > 0:08:13WHALE SONG
0:08:14 > 0:08:17That's it! The bowhead whales!
0:08:17 > 0:08:20Tough enough to smash through anything!
0:08:20 > 0:08:22Yeah, hup-da-whale!
0:08:22 > 0:08:23Good thinking, Tunip.
0:08:23 > 0:08:27Now all we have to do is find our new bowhead whale friends.
0:08:27 > 0:08:32Let's call them to the Octopod by playing their songs.
0:08:36 > 0:08:40Try it louder, Dashi. We don't have much time.
0:08:53 > 0:08:54THEY CHEER
0:08:57 > 0:09:00- Super, super!- Howdy, y'all!
0:09:00 > 0:09:02We need your help.
0:09:02 > 0:09:06Narwhals are trapped in the ice and we can't break them free.
0:09:06 > 0:09:10We bowheads are the greatest icebreakers in the seven seas,
0:09:10 > 0:09:12- ain't that right, boys? - That's right!
0:09:12 > 0:09:15You ready to take a ride, partner?
0:09:15 > 0:09:20- Captain, help is on the way. - Thanks, Dashi. How much longer?
0:09:20 > 0:09:22- Whoo-hoo!- Look!
0:09:22 > 0:09:24Yeeehah! Whoooo!
0:09:26 > 0:09:30Aaagh! Boris, narwhals, everyone! Get back!
0:09:41 > 0:09:44Yeah! Ha ha ha!
0:09:50 > 0:09:53THEY GASP AND BREATHE
0:10:02 > 0:10:04Now that's what I call a ride!
0:10:04 > 0:10:07ALL CHEERING
0:10:08 > 0:10:12Captain Barnacles, my dear old friend.
0:10:12 > 0:10:15Thanks to you and your Octonaut crew for saving us.
0:10:15 > 0:10:21- And you too, our mighty bowhead whale friends.- Oh, shucks, Boris.
0:10:21 > 0:10:25Weren't nothing. Always glad to help a fellow whale in need.
0:10:25 > 0:10:26Yes, thank you, bowheads.
0:10:26 > 0:10:30It's amazing what you can do when you put your heads together!
0:10:30 > 0:10:35Hee hee hee! Especially when you've got heads THIS big!
0:10:35 > 0:10:38Ain't that right, boys? Happy trails, partners!
0:10:38 > 0:10:40- Yip, yip, yip!- Yahoo!
0:10:40 > 0:10:44- Bye!- Bye!- Cheerio! - Thanks for the ride!
