0:00:02 > 0:00:05- SIREN WAILS - 'Octonauts, to your stations!'
0:00:07 > 0:00:08Barnacles!
0:00:08 > 0:00:09Kwazii!
0:00:09 > 0:00:11Peso!
0:00:38 > 0:00:41- Explore!- Rescue!- Protect!
0:00:41 > 0:00:43Octonauts!
0:00:49 > 0:00:51A WHALE SINGS
0:00:53 > 0:00:55What are you doing, maties?
0:00:55 > 0:01:00We are listening to the most popular song of the summer.
0:01:00 > 0:01:04Er, doesn't sound like any sea shanty I've ever heard.
0:01:04 > 0:01:08That's because it's a whale song made by humpback whales.
0:01:08 > 0:01:10Look.
0:01:10 > 0:01:12Whoa!
0:01:12 > 0:01:16These whales are on their way to their summer feeding grounds.
0:01:16 > 0:01:19They use their songs to talk to each other
0:01:19 > 0:01:23and they can hear the songs even when they are miles and miles apart.
0:01:23 > 0:01:27The song they are singing now has been really popular this year.
0:01:27 > 0:01:31All the humpbacks are singing it. It's the only song on the radio.
0:01:31 > 0:01:32Listen.
0:01:32 > 0:01:35- WHALE SINGS - Here,
0:01:35 > 0:01:38here and here.
0:01:38 > 0:01:42Humpbacks all over the world are singing the exact same song.
0:01:42 > 0:01:44- Incredible.- Let me try.
0:01:45 > 0:01:47Hang on. That's new.
0:01:47 > 0:01:50Maybe they got tired of the old song.
0:01:50 > 0:01:54No, I mean it sounds different. I've never heard a voice like it before.
0:01:54 > 0:01:58- Maybe these whales have, Dashi. - Good idea, Captain.
0:01:58 > 0:02:02- Excuse me, humpback whales.- Yes?
0:02:02 > 0:02:06Sorry to interrupt your journey but we just wondered if you'd ever
0:02:06 > 0:02:08heard a song like this before.
0:02:08 > 0:02:10WHALE SINGS
0:02:11 > 0:02:13Er, no. Not heard that before.
0:02:13 > 0:02:16It doesn't even sound like a humpback.
0:02:16 > 0:02:21The singing doesn't match anything in the Octopod sound collection.
0:02:21 > 0:02:23Whatever's making that noise,
0:02:23 > 0:02:27- there's nothing like it in the ocean.- This could be an entirely new
0:02:27 > 0:02:30- species of whale.- Or an entirely new species of sea monster.
0:02:30 > 0:02:33Well, there's only one way to find out.
0:02:33 > 0:02:36Octonauts, it's time to investigate.
0:02:36 > 0:02:39I'm picking up something big on the tracker. Very big.
0:02:39 > 0:02:43It should be on the other side of this reef.
0:02:44 > 0:02:46Ah! There's nothing here.
0:02:46 > 0:02:49- No, but I thought I saw something. - Me, too.
0:02:49 > 0:02:53- Something big.- The tracker is still saying it's up ahead.
0:02:53 > 0:02:55Then let's go, maties.
0:02:58 > 0:03:00It's gone again.
0:03:00 > 0:03:03I get the feeling it doesn't want to be disturbed.
0:03:03 > 0:03:07Let's go forward gently this time so we don't scare it,
0:03:07 > 0:03:08whatever it is.
0:03:08 > 0:03:12WHALE SINGS
0:03:12 > 0:03:15- Hear that?- It sounds so sad.
0:03:15 > 0:03:18Like the world's loneliest sea monster.
0:03:20 > 0:03:23Or the world's loneliest whale.
0:03:23 > 0:03:25That's a humpback whale.
0:03:25 > 0:03:28But his voice is like no humpback I've ever heard.
0:03:28 > 0:03:31I think he's looking for food.
0:03:31 > 0:03:34He's a young one and he looks very skinny, Captain.
0:03:34 > 0:03:37Then he might need our help. Activate helmets.
0:03:40 > 0:03:45Hello there. That's a very interesting song you're singing.
0:03:45 > 0:03:49Oh, thanks. It's my "I'm hungry" song.
0:03:49 > 0:03:50My name's Joe, by the way.
0:03:50 > 0:03:52Are you on your own, Joe?
0:03:52 > 0:03:56Yep, I'm pretty much always on my own.
0:03:56 > 0:04:00I guess the other humpbacks kind of don't understand my singing.
0:04:00 > 0:04:03Captain, Joe is far from the summer feeding grounds.
0:04:03 > 0:04:06Without the other whales to show him the way,
0:04:06 > 0:04:10- he won't have enough to eat. - Joe, why don't you come with us
0:04:10 > 0:04:13to our Octopod and we'll see if we can help you?
0:04:13 > 0:04:16I don't suppose there's any food at this here Octopod?
0:04:16 > 0:04:18I'm kind of hungry.
0:04:18 > 0:04:19Absolutely.
0:04:19 > 0:04:22- Follow us.- Right behind you.
0:04:29 > 0:04:33Mm, These here fish biscuits are pretty good.
0:04:33 > 0:04:37Captain, I think I have found the cause of Joe's unusual voice.
0:04:37 > 0:04:38What is it, Peso?
0:04:40 > 0:04:42These are the tubes inside Joe's nose
0:04:42 > 0:04:46and these are the tubes inside a typical humpback's nose.
0:04:46 > 0:04:49- See how much smaller Joe's are? - Of course.
0:04:49 > 0:04:51Whales sing by pushing air through their nose,
0:04:51 > 0:04:55but because Joe's tubes are so narrow, his songs sound different.
0:04:55 > 0:05:00Aha. So that's why the other whales can't understand me.
0:05:00 > 0:05:01RUMBLING NOISE
0:05:01 > 0:05:03Wow! What was that?!
0:05:03 > 0:05:06Oh, gee! Just my tummy rumbling.
0:05:06 > 0:05:10I don't suppose you have any more of those fish biscuits?
0:05:10 > 0:05:12Captain, Joe can't just eat fish biscuits.
0:05:12 > 0:05:14He needs a proper whale diet.
0:05:14 > 0:05:17Yeah, and the vegetables need a break.
0:05:17 > 0:05:21Hmm. Joe needs food, and fast, so we need to get him
0:05:21 > 0:05:23to join a group of whales
0:05:23 > 0:05:26who'll show him to the summer feeding grounds.
0:05:26 > 0:05:28The last group is on its way to the feeding grounds.
0:05:28 > 0:05:30After they've gone,
0:05:30 > 0:05:32there are no more humpbacks in this part of the ocean.
0:05:32 > 0:05:35Then time is running out.
0:05:35 > 0:05:37Dashi, sound the Octo-alert!
0:05:37 > 0:05:39Octonauts to the launch bay!
0:05:48 > 0:05:51Octonauts, Joe here is hungry and all alone.
0:05:51 > 0:05:53If we're going to help him,
0:05:53 > 0:05:57we need to find a way to make the other whales understand Joe's song.
0:05:57 > 0:06:00I might have an idea, captain.
0:06:00 > 0:06:04With a little help, I think I could build a special machine that Joe
0:06:04 > 0:06:07can wear that will make his voice sound like the other humpbacks.
0:06:07 > 0:06:09Oh, really?
0:06:09 > 0:06:11But won't that take a long time?
0:06:11 > 0:06:14I'll have it done faster than you can say
0:06:14 > 0:06:17bunch of munchy crunchy fish biscuits!
0:06:17 > 0:06:21It's our best shot. Octonauts, let's do this!
0:06:30 > 0:06:32Mmm!
0:06:37 > 0:06:40All right, everybody, take a look.
0:06:40 > 0:06:43This here is the Joe Coder.
0:06:43 > 0:06:48Here you are, Joe. You can wear the Joe Coder on your neck.
0:06:48 > 0:06:51Just jab it with your fin when you want to sing,
0:06:51 > 0:06:54and your songs will go from this...
0:06:54 > 0:06:55Go-ahead, Joe!
0:06:55 > 0:06:58HIGH-PITCHED WHALE SONG
0:06:58 > 0:06:59..to this!
0:06:59 > 0:07:04DEEP SINGING
0:07:04 > 0:07:08Hey! I sound like a regular humpback!
0:07:08 > 0:07:09Now I can... Oh!
0:07:12 > 0:07:14Nothing to worry about, I've just got to fix this.
0:07:14 > 0:07:16Too loud!
0:07:24 > 0:07:27Phew, the problem is fixed.
0:07:27 > 0:07:30But now Joe's gone. The loud noise frightened him.
0:07:30 > 0:07:34We better find him fast or the other humpbacks will be gone for good.
0:07:34 > 0:07:36There's no time to lose. Let's go!
0:07:39 > 0:07:40No sign of him, captain.
0:07:40 > 0:07:43We found Joe before, so we can do it again.
0:07:43 > 0:07:47Peso, check the tracker and look for a big shape.
0:07:47 > 0:07:51I'm looking at the tracker, and it's covered in big shapes.
0:07:51 > 0:07:55Of course, we're surrounded by whales.
0:07:55 > 0:07:57We have to find Joe before they pass by
0:07:57 > 0:07:59on their way to the feeding ground.
0:07:59 > 0:08:00Maybe we could sing.
0:08:00 > 0:08:03I'm not sure now is the time for singing!
0:08:03 > 0:08:08No, I mean, what if we could use the coder to make me sound like Joe?
0:08:08 > 0:08:12Good idea! Then Joe will want to see who else sings like him.
0:08:12 > 0:08:13Tweak!
0:08:13 > 0:08:16I'll just change that and reverse this,
0:08:16 > 0:08:20and there! That ought to do the trick.
0:08:20 > 0:08:23Right, Peso, go for it!
0:08:24 > 0:08:28Well, here goes nothing. I hope you're listening, Joe.
0:08:30 > 0:08:33HE SINGS A WHALE SONG
0:08:33 > 0:08:35What was that?
0:08:35 > 0:08:39It might be my tummy, I think I ate something funny for lunch.
0:08:41 > 0:08:44HE SINGS HIGHER
0:08:44 > 0:08:47Keep trying, peso, you can do it!
0:08:49 > 0:08:51PESO SINGS AGAIN
0:08:53 > 0:08:55- That's it!- He's done it, Captain!
0:08:55 > 0:08:58Now we just have to hope Joe can hear it,
0:08:58 > 0:09:00and wants to see who's singing his song.
0:09:03 > 0:09:06There aren't many whales left to pass, Captain.
0:09:06 > 0:09:10- Soon it'll be too late. - Come on, Joe, where are you?
0:09:12 > 0:09:16What? That sounds like my voice!
0:09:19 > 0:09:22Peso! Where did you learn to sing like that?
0:09:22 > 0:09:25I'll show you, Joe.
0:09:25 > 0:09:28Oh, it ain't going to make that terrible noise again, is it?
0:09:28 > 0:09:31It's fixed, I promise.
0:09:32 > 0:09:34HE SINGS DEEPLY
0:09:34 > 0:09:39Wow, I can't believe it. It worked!
0:09:39 > 0:09:41HE SINGS
0:09:42 > 0:09:44Now, that's more like it.
0:09:44 > 0:09:47Let's just hope someone is listening.
0:09:47 > 0:09:53- Hey, who's that singing? - What a great song!
0:09:53 > 0:09:55It's our pal Joe.
0:09:55 > 0:10:00- I love your style!- We're on our way to the feeding grounds.
0:10:00 > 0:10:04- You should come with us. - Oh, gee, thanks!
0:10:04 > 0:10:09And thank you, Octonauts, for helping me sing my song.
0:10:09 > 0:10:10SINGING
0:10:10 > 0:10:15Listen! They're all singing your song! Now, go!
0:10:20 > 0:10:21Good work, everyone.
0:10:21 > 0:10:24Joe should have no trouble finding the feeding grounds,
0:10:24 > 0:10:26now that he's teamed up with the other humpbacks.
0:10:26 > 0:10:31- And they really seem to like his song.- It's not just Joe's friends.
0:10:31 > 0:10:33Humpbacks are singing it everywhere!
0:10:33 > 0:10:36WHALES SING
0:10:36 > 0:10:39THE VEGETABLES SING ALONG
0:10:39 > 0:10:42It looks like it's catching on here too!
