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!
0:00:41 > 0:00:43Octonauts!
0:00:57 > 0:01:02Why aren't there fish or any other creature swimming around here?
0:01:02 > 0:01:05Aye, where'd all the little fishies go?
0:01:05 > 0:01:08Oh, this is creepy.
0:01:08 > 0:01:10It's like a ghost town down here.
0:01:10 > 0:01:13Urgh! You mean a GROSS town.
0:01:13 > 0:01:16Shellington, what is this green mess?
0:01:16 > 0:01:20It's algae. Algae is a common plant in the ocean,
0:01:20 > 0:01:24but there's a lot more here than usual.
0:01:24 > 0:01:27SHE STRUGGLES
0:01:28 > 0:01:33Yep, all this slimy algae keeps clogging up the Octopod
0:01:33 > 0:01:35faster than I can clean it out. Urgh!
0:01:35 > 0:01:37Oh!
0:01:37 > 0:01:38TWEAK LAUGHS
0:01:38 > 0:01:43- Sorry about that, Dashi. Didn't see you there behind me.- Urgh!
0:01:44 > 0:01:46Huh! Avast, mateys!
0:01:46 > 0:01:49- Over here!- What is it, Kwazii?
0:01:49 > 0:01:51Look!
0:01:51 > 0:01:53THEY ALL GASP
0:01:53 > 0:01:56THE LOBSTERS AND CRABS COUGH
0:01:56 > 0:01:57Professor Inkling,
0:01:57 > 0:02:01'do you see how slowly those lobsters and crabs are moving?'
0:02:01 > 0:02:04I do, Shellington. Very strange.
0:02:04 > 0:02:07'Do you think it has anything to do with the algae?'
0:02:07 > 0:02:11Hmm, not sure. Though this does seem familiar.
0:02:11 > 0:02:15These creatures are poorly. We have to help them, Captain.
0:02:15 > 0:02:19Agreed. But first we have to work out what's wrong.
0:02:19 > 0:02:22SNAIL STRUGGLES FOR BREATH
0:02:22 > 0:02:25Ah, poor little fella. What do you make of this, Kwazii?
0:02:25 > 0:02:27Never seen anything quite like it.
0:02:27 > 0:02:31Psst! Come on, this way.
0:02:31 > 0:02:34All this algae seems to be making them ill.
0:02:36 > 0:02:39Professor, have you ever heard of such a thing?
0:02:39 > 0:02:43I've observed this problem before, but where?
0:02:46 > 0:02:51Hold on, Shellington. I can check my books. To the library!
0:02:58 > 0:03:00Cap, look at this.
0:03:02 > 0:03:05There's a leak in this pipe.
0:03:05 > 0:03:09Hmm. I wonder if that could be part of the... Huh?
0:03:09 > 0:03:10Oh!
0:03:13 > 0:03:14BOTH: Whoa!
0:03:14 > 0:03:18Oh, no. The Octopod is taking off without us.
0:03:20 > 0:03:22VEGIMALS SQUEAL
0:03:26 > 0:03:28We've got to catch the Octopod.
0:03:32 > 0:03:34Octonauts, to the GUPs.
0:03:44 > 0:03:49Octonauts, we've got to get back on board the Octopod.
0:03:53 > 0:03:56SPLAT Yuck!
0:03:56 > 0:03:57More algae!
0:03:57 > 0:04:01Kwazii, activate windscreen wipers.
0:04:01 > 0:04:02Aye, Captain.
0:04:05 > 0:04:10GUP-A, to Octopod, GUP-A to Octopod. Come in, Octopod.
0:04:12 > 0:04:15Professor Inkling, this is Captain Barnacles.
0:04:15 > 0:04:19Can you hear me? Please come in.
0:04:19 > 0:04:21- MUSIC PLAYS - 'GUP-A to Octopod.
0:04:21 > 0:04:24'Is anyone there? Come in.'
0:04:24 > 0:04:28Hmm, now, where are my books about algae?
0:04:28 > 0:04:31I know they're here somewhere.
0:04:31 > 0:04:32No-one's answering.
0:04:32 > 0:04:37That's odd. I was just talking to the professor a few minutes ago.
0:04:37 > 0:04:41I hope he's OK. Maybe he's taking a nap.
0:04:41 > 0:04:47If it's not the professor, then who's stealing the Octopod?
0:04:55 > 0:04:58THEY GASP
0:04:58 > 0:04:59Ah, here we are.
0:04:59 > 0:05:01Algae.
0:05:01 > 0:05:04Lots Of Algae.
0:05:04 > 0:05:06Lots And Lots Of Algae.
0:05:06 > 0:05:09Captain Barnacles, if I can just get close enough,
0:05:09 > 0:05:12I think I can grab the Octopod.
0:05:12 > 0:05:13Go for it, Tweak.
0:05:21 > 0:05:23Gotcha!
0:05:25 > 0:05:27Bull's-eye!
0:05:27 > 0:05:28Woo-hoo!
0:05:28 > 0:05:30Well done.
0:05:31 > 0:05:32Whoa!
0:05:32 > 0:05:34ALL: Whoa!
0:05:36 > 0:05:40We've got to get back on board the Octopod. Are you with me, Kwazii?
0:05:40 > 0:05:42Aye, matey.
0:05:42 > 0:05:44Peso, you drive.
0:05:44 > 0:05:46Me? Aye-aye, sir.
0:05:46 > 0:05:49Octonauts, let's do this.
0:05:51 > 0:05:54THEY STRUGGLE
0:06:00 > 0:06:01CAMERA CLICKS
0:06:13 > 0:06:16- Aargh!- Huh!
0:06:16 > 0:06:19CAPTAIN BARNACLES STRUGGLES
0:06:20 > 0:06:23That was a close one. Thanks, Captain.
0:06:23 > 0:06:26Come on, we've got to get to the Octo-hatch.
0:06:26 > 0:06:28Professor Inkling could be in trouble.
0:06:30 > 0:06:33Ah! All About Algae.
0:06:33 > 0:06:36Everything About Algae.
0:06:36 > 0:06:39Everything Else About Algae, ah.
0:06:39 > 0:06:41KWAZII STRUGGLES
0:06:46 > 0:06:47She won't open!
0:06:47 > 0:06:50Let me try.
0:06:50 > 0:06:55Sometimes it takes some polar bear strength.
0:06:55 > 0:06:58Combined with some cat-like quickness!
0:07:00 > 0:07:01Hah!
0:07:01 > 0:07:04BOTH: To get the job done! Hey!
0:07:04 > 0:07:06Follow me.
0:07:21 > 0:07:22THEY GASP
0:07:22 > 0:07:26Kwazii, are you seeing what I'm seeing?
0:07:26 > 0:07:28Shiver me whiskers!
0:07:28 > 0:07:32The Octopod was taken by these crusty little fellas?
0:07:43 > 0:07:44Ahem.
0:07:44 > 0:07:46Uh-oh.
0:07:46 > 0:07:48Run for it!
0:07:48 > 0:07:51THE CRABS AND LOBSTERS COUGH
0:07:51 > 0:07:52Hoy-ah! Hah!
0:07:56 > 0:08:01All right, all right. We give up. You've got us.
0:08:01 > 0:08:04Why did you crabs and lobsters take the Octopod?
0:08:04 > 0:08:07THEY COUGH
0:08:07 > 0:08:10And why are you all coughing and wheezing?
0:08:10 > 0:08:13I ain't going to lie to you.
0:08:13 > 0:08:17Me and my friends here, we were feeling ill.
0:08:17 > 0:08:21So we, erm, borrowed your Octopod.
0:08:21 > 0:08:25Because to get better, we had to leave our home
0:08:25 > 0:08:29and go some place where there isn't so much algae.
0:08:29 > 0:08:30Jumping jellyfish!
0:08:33 > 0:08:37So all that algae WAS making you ill!
0:08:37 > 0:08:41But where did all that algae come from in the first place?
0:08:41 > 0:08:46Hmm. I wonder if the water's polluted.
0:08:47 > 0:08:52- Polluted?- That's when things get into the water that shouldn't be there,
0:08:52 > 0:08:56which could make the algae grow until there's too much of it.
0:08:56 > 0:08:59But what's polluting the water?
0:08:59 > 0:09:01Cap, the leaky pipe!
0:09:01 > 0:09:06That's right! The pipe must be putting something bad in the water.
0:09:06 > 0:09:10What about the other creatures still there? They may need help.
0:09:10 > 0:09:12That's right, Peso.
0:09:12 > 0:09:15That's why we're going back to fix that leaky pipe
0:09:15 > 0:09:17and clean up that extra algae.
0:09:17 > 0:09:19I've got it! It's right in this book.
0:09:19 > 0:09:23The water's polluted, causing algae to grow,
0:09:23 > 0:09:25which is making creatures ill. Ha-ha!
0:09:26 > 0:09:29What? Did I miss something?
0:09:33 > 0:09:36Octonauts, let's clean up this water.
0:09:36 > 0:09:39- Right away.- I'm on it!- Aye-aye!
0:10:00 > 0:10:02Yah! Hoy-ah!
0:10:04 > 0:10:06There. That should do it.
0:10:12 > 0:10:14Welcome home.
0:10:14 > 0:10:16We've cleaned up the extra algae,
0:10:16 > 0:10:19and fixed the pipe that caused it to grow too much.
0:10:19 > 0:10:23THEY BREATHE DEEPLY
0:10:23 > 0:10:27Hmm, just right.
0:10:27 > 0:10:30Yeah, much better. Thanks, Octonauts.
0:10:30 > 0:10:32Sorry for taking your ship.
0:10:32 > 0:10:35Now you won't have to leave your home ever again.
0:10:35 > 0:10:38Or run away with your Octopod!
0:10:38 > 0:10:40THEY ALL LAUGH
