0:00:00 > 0:00:00- Subtitles
0:00:02 > 0:00:04- Octonots, to your stations.
0:00:06 > 0:00:07- Cwrwgl.
0:00:08 > 0:00:09- Harri.
0:00:09 > 0:00:11- Pegwn.
0:00:37 > 0:00:38- Explore.
0:00:38 > 0:00:39- Rescue.
0:00:39 > 0:00:40- Rescue.- - Protect.
0:00:52 > 0:00:57- This little reef is only a few years - old, but it's already full of life.
0:00:57 > 0:01:01- Aye, this reef is busy. - Even if it's not very big.
0:01:01 > 0:01:04- Hey, it's big enough!
0:01:04 > 0:01:07- Who said that? Show yourself.
0:01:07 > 0:01:13- Here I am, I'm a frog fish, - my name's Carwyn.
0:01:13 > 0:01:17- You look so much like the reef, - I didn't see you there.
0:01:17 > 0:01:18- That is the idea.
0:01:19 > 0:01:24- I'm camouflaged, which means - I blend in with what's around me.
0:01:24 > 0:01:29- It keeps me safe from fish who - want to eat me, like those sharks.
0:01:30 > 0:01:31- Sharks!
0:01:32 > 0:01:34- Everybody, hide!
0:01:40 > 0:01:42- I thought I smelt food.
0:01:42 > 0:01:45- Let's head to a bigger reef.
0:01:45 > 0:01:47- See what I mean?
0:01:48 > 0:01:50- Ha, ha, ha! You fooled them, matey!
0:01:50 > 0:01:54- Fascinating, these other fish - can't blend in like the frog fish...
0:01:55 > 0:01:58- ..but the reef has lots of places - for them to hide.
0:01:58 > 0:02:01- This reef keeps us - and all our friends safe.
0:02:01 > 0:02:04- It is our home, sweet home.
0:02:05 > 0:02:06- Whoa, look out!
0:02:08 > 0:02:10- Sorry about that.
0:02:10 > 0:02:13- I fixed the paddles but now - the sub steering isn't right.
0:02:14 > 0:02:18- And as soon as you've fixed the - steering, something else will break.
0:02:19 > 0:02:23- I know, but she's the first sub - I built, so I can't give up on her.
0:02:23 > 0:02:27- Maybe if I pedal a little faster.
0:02:27 > 0:02:29- Yup, that's good.
0:02:29 > 0:02:31- Whoa!
0:02:32 > 0:02:33- No, that's bad.
0:02:35 > 0:02:37- Matey, are you alright?
0:02:38 > 0:02:41- Yup, but now - I've got to fix the steering...
0:02:42 > 0:02:45- ..the pedal, the rudder, - the top, the bottom...
0:02:45 > 0:02:50- Is there anything on the sub - that doesn't need fixing?
0:02:50 > 0:02:52- The seats are still comfy.
0:02:52 > 0:02:53- Ooooh!
0:02:54 > 0:02:58- There's a hurricane on the way.
0:02:58 > 0:03:02- Harri, Cregynog and Ira, there's - a hurricane heading your way.
0:03:03 > 0:03:04- And it's moving fast.
0:03:05 > 0:03:08- Take cover in the subs, - there's not enough time to return.
0:03:08 > 0:03:12- We'll ride out the storm in the sub.
0:03:12 > 0:03:15- Very good - good luck.
0:03:15 > 0:03:17- There's a hurricane about to hit.
0:03:17 > 0:03:20- There's a hurricane about to hit.- - Storm coming, everyone, take cover!
0:03:33 > 0:03:35- I've got to go back for the sub.
0:03:35 > 0:03:37- There's no time!
0:03:59 > 0:04:03- Harri, Ira, Cregynog, - are you all alright?
0:04:03 > 0:04:07- The sub took a pounding - but she's still in one piece.
0:04:08 > 0:04:11- Wish I could say the same - about the other sub.
0:04:12 > 0:04:14- Huh! The reef!
0:04:21 > 0:04:24- Jumping jellyfish! - There's nothing left.
0:04:25 > 0:04:29- Where's Carwyn? Ahoy, matey. - Glad I found you.
0:04:30 > 0:04:32- Oh, I'm not.
0:04:33 > 0:04:36- If I'm that easy to see, - then I'm not camouflaged.
0:04:36 > 0:04:38- How will I hide from the sharks?
0:04:39 > 0:04:41- We can't hide either.
0:04:41 > 0:04:47- I see what you mean. Captain, - the coral reef's been destroyed...
0:04:47 > 0:04:51- ..and these fish need a new place - to live. We must do something.
0:04:51 > 0:04:54- Agreed. Sound the Octo-alert.
0:04:55 > 0:04:57- To the launch bay!
0:05:06 > 0:05:09- The reef dwellers need our help.
0:05:09 > 0:05:14- Their home was destroyed and now - they have no shelter or protection.
0:05:14 > 0:05:17- Maybe we could move the fish to - another reef?
0:05:17 > 0:05:21- There may not be time before the - second part of the hurricane hits.
0:05:22 > 0:05:23- Second part!
0:05:24 > 0:05:28- A hurricane starts with strong winds - and waves that stir up the ocean.
0:05:29 > 0:05:33- Then there's calm because we're - in the quiet centre of the storm...
0:05:34 > 0:05:35- ..known as the eye.
0:05:35 > 0:05:40- After the eye passes, it's followed - by winds and even stronger waves.
0:05:41 > 0:05:44- The fish will never survive that - without a reef.
0:05:44 > 0:05:48- Hmmm, what if we build them - a new reef?
0:05:48 > 0:05:52- You're talking about making - an artificial reef, Captain.
0:05:52 > 0:05:54- Bababaw artificial reefa!
0:05:55 > 0:05:58- An artificial reef - can be made out of anything.
0:05:58 > 0:06:01- A sunken ship - or even an old train carriage.
0:06:01 > 0:06:05- Algae, sponges, coral and plants - attach themselves to it...
0:06:06 > 0:06:08- ..and that attracts fish.
0:06:08 > 0:06:11- But what could we use - to make an artificial reef?
0:06:12 > 0:06:16- Well, the truth is that the sub - isn't much of a sub any more.
0:06:18 > 0:06:21- But it would make - a great artificial reef.
0:06:23 > 0:06:25- Great idea! - But we'll have to work fast.
0:06:26 > 0:06:30- The first step, we should cover the - sub with algae and coral, Captain.
0:06:30 > 0:06:32- Using sticky limpet glue.
0:06:33 > 0:06:36- Let's do this!
0:07:00 > 0:07:02- Much better!
0:07:02 > 0:07:04- Well, what do you think?
0:07:05 > 0:07:08- It has plenty of places - for me to blend in.
0:07:08 > 0:07:11- And plenty of hiding places - for the rest of us.
0:07:11 > 0:07:13- I say, let's move in.
0:07:13 > 0:07:17- I say, let's move in.- - Hold on, don't touch anything yet.
0:07:18 > 0:07:20- The sticky limpet glue - still needs time to dry.
0:07:21 > 0:07:25- Th second half of the storm - is coming and it's going to be big.
0:07:26 > 0:07:31- The glue hasn't hardened. Everything - that was put on will wash away.
0:07:32 > 0:07:33- Oh, no.
0:07:33 > 0:07:35- What shall we do?
0:07:35 > 0:07:37- Oh, no, the tragedy!
0:07:37 > 0:07:39- This is a disaster!
0:07:39 > 0:07:43- Don't worry, me hearties, - we always have a backup plan.
0:07:43 > 0:07:45- A backup plan?
0:07:47 > 0:07:50- Shame the reef doesn't have - a helmet, like we do.
0:07:50 > 0:07:54- Hmmm, maybe we can give it one.
0:08:02 > 0:08:06- Hatch sealed. OK, lower the towline.
0:08:13 > 0:08:14- Now, take it away.
0:08:14 > 0:08:15- Got it, Cap.
0:08:24 > 0:08:27- Easy now... and down.
0:08:28 > 0:08:31- Ho-ho, a cover! Wonderful. - Thank you so much.
0:08:32 > 0:08:36- The dome will protect the reef, - but if it takes a direct hit...
0:08:36 > 0:08:38- ..I can't guarantee it will hold.
0:08:38 > 0:08:42- Can you give me the exact direction - the hurricane will hit from?
0:08:43 > 0:08:45- Sending it to you right now.
0:08:47 > 0:08:51- We'll line up the subs - and form a wall...
0:08:51 > 0:08:56- ..to stop the hurricane - from hitting the reef too hard.
0:08:56 > 0:08:59- I'll use the sub to try - and keep the dome steady.
0:09:02 > 0:09:04- Stay close together.
0:09:05 > 0:09:09- Hurricane force current - will hit in five... four...
0:09:10 > 0:09:13- ..three... two... one.
0:09:13 > 0:09:14- Brace yourselves.
0:09:36 > 0:09:41- The sub can't keep the dome steady. - We're going to lose it.
0:09:41 > 0:09:44- Re-group around the dome.
0:10:00 > 0:10:03- The hurricane is over.
0:10:04 > 0:10:05- Oh, yes!
0:10:05 > 0:10:07- Thank you, Octonots.
0:10:08 > 0:10:13- Where's Carwyn? I can't find him. - I don't see him anywhere.
0:10:13 > 0:10:18- You're not looking close enough. - How's that for camouflage?
0:10:19 > 0:10:22- Well done, matey. Glad you're safe.
0:10:22 > 0:10:25- This reef is perfect - for frog fish like me.
0:10:25 > 0:10:28- And for us too.
0:10:28 > 0:10:29- And for us too.- - We love it.
0:10:30 > 0:10:34- Well, I admit that the old sub - was never the fanciest sub...
0:10:34 > 0:10:39- ..but I'm proud to say - that it sure is the homiest sub.
0:10:39 > 0:10:40- It's wonderful in here.
0:10:40 > 0:10:42- It's wonderful in here.- - Perfect!
0:10:58 > 0:10:58- .
