0:01:29 > 0:01:31- Yiaow!
0:01:31 > 0:01:34- Easy, Harri! We'll find some more.
0:01:41 > 0:01:46- There should be an algae patch on - the other side of this coral reef.
0:01:46 > 0:01:51- That coral reef looks sick. - It's all white.
0:01:51 > 0:01:53- Let's stop and investigate.
0:01:56 > 0:01:58- There's more sick coral over here.
0:01:59 > 0:02:01- This reef needs a full check-up.
0:02:01 > 0:02:05- Pegwn, you and Cregynog - check this side of the coral reef.
0:02:05 > 0:02:08- Harri, we'll take the other side.
0:02:10 > 0:02:13- No sick coral on this side so far.
0:02:13 > 0:02:15- Whoa! That's a lot of algae.
0:02:15 > 0:02:18- We might as well collect some.
0:02:19 > 0:02:20- Harri?
0:02:20 > 0:02:23- My old friend, Parrot Fish Pete.
0:02:23 > 0:02:24- My old friend, Parrot Fish Pete.- - Hello, Pete.
0:02:24 > 0:02:29- Keep your voices down. - I'm trying to sneak some algae.
0:02:29 > 0:02:32- Why do you have to... - Why do you have to sneak it?
0:02:33 > 0:02:35- Because of those damsel fish.
0:02:35 > 0:02:40- They guard that algae as if it - were a treasure chest full of gold.
0:02:40 > 0:02:42- Wish me luck.
0:02:45 > 0:02:46- Keep off the algae!
0:02:47 > 0:02:50- I just want my fair share. - Nothing more, nothing less.
0:02:50 > 0:02:54- Scram! Damsel fish only.
0:02:58 > 0:03:00- Sand squirt!
0:03:02 > 0:03:04- They had you outnumbered.
0:03:04 > 0:03:08- Aye. At least I got away - by squirting sand.
0:03:08 > 0:03:10- Oh, there goes my pal, Pigyn!
0:03:10 > 0:03:12- Maybe she can get to the algae.
0:03:13 > 0:03:16- Yikes! Talk to the spikes.
0:03:16 > 0:03:17- You alright?
0:03:18 > 0:03:23- My spikes protected me. I didn't get - anything to eat. Not even a nibble.
0:03:24 > 0:03:25- Coming through!
0:03:25 > 0:03:28- Yum-yum-yum... Oh!
0:03:28 > 0:03:30- Get him, boys!
0:03:33 > 0:03:35- Hi, Prys.
0:03:35 > 0:03:37- Hi, Pete.
0:03:38 > 0:03:39- Hungry?
0:03:44 > 0:03:46- I give up but I'm still...
0:03:46 > 0:03:48- I give up but I'm still...- - Hungry?
0:03:48 > 0:03:50- A lot of fish are hungry...
0:03:50 > 0:03:54- ..because they can't get - past the damsel fish to eat.
0:03:54 > 0:03:59- Pegwn to Cwrwgl. We've found more - sick coral on this side of the reef.
0:03:59 > 0:04:01- Meet us back at the sub.
0:04:04 > 0:04:08- There's a connection between the - sick coral and those damsel fish.
0:04:09 > 0:04:11- Damsel fish grow algae to eat.
0:04:11 > 0:04:15- When they don't let other fish eat - it, there's too much algae.
0:04:15 > 0:04:17- The extra algae makes the reef sick.
0:04:18 > 0:04:21- Pete's friends keep the algae - from spreading too far.
0:04:21 > 0:04:26- If they can eat some of the algae, - the reef will get better.
0:04:26 > 0:04:31- Damsel fish are protective - of the algae they grow.
0:04:31 > 0:04:35- They won't listen - to algae-eating fish like us.
0:04:35 > 0:04:38- Don't worry. - We'll talk to them for you.
0:04:39 > 0:04:44- Excuse me. We'd like to talk to you - about a problem on the coral reef.
0:04:44 > 0:04:47- You got a problem? Talk to the boss.
0:04:48 > 0:04:52- The one with the spot on his face.
0:04:52 > 0:04:56- A big spot? I don't see - a damsel fish with a big spot.
0:04:57 > 0:05:00- Damsel fish - can see colours we can't.
0:05:00 > 0:05:05- If you want to see that spot, you'll - have to set your binoculars to...
0:05:05 > 0:05:09- Damsel-fish vision. - What will Ira think of next?
0:05:11 > 0:05:12- Ah! That's better.
0:05:14 > 0:05:15- A-ha! The spot.
0:05:16 > 0:05:18- Excuse me. Are you the boss?
0:05:18 > 0:05:23- Certainly I am. Keep off the algae!
0:05:23 > 0:05:28- We're the Octonots. We've discovered - some trouble on this coral reef.
0:05:29 > 0:05:31- There's no trouble - for us damsel fish.
0:05:32 > 0:05:35- We're sitting pretty - with more algae than we can eat.
0:05:35 > 0:05:37- Ain't that right, boys?
0:05:37 > 0:05:38- Ain't that right, boys?- - Right, boss.
0:05:39 > 0:05:42- Too much algae - makes the coral reef sick.
0:05:43 > 0:05:45- You can save the coral reef...
0:05:45 > 0:05:48- ..if you let other fish - eat the algae too.
0:05:48 > 0:05:55- Forget about it. This is my algae - farm and I don't ever leave it.
0:05:55 > 0:05:56- Now scram!
0:05:56 > 0:05:58- Now scram!- - Yiaow.
0:05:58 > 0:06:01- Easy, Harri! We'll scram.
0:06:02 > 0:06:05- If the boss never leaves - his algae farm...
0:06:05 > 0:06:07- ..he has no idea - the coral reef is sick.
0:06:08 > 0:06:10- We need to get the boss - off his farm.
0:06:11 > 0:06:12- Aye, but how?
0:06:13 > 0:06:15- We'll take his algae.
0:06:15 > 0:06:17- Take his algae?
0:06:17 > 0:06:18- I'll explain.
0:06:20 > 0:06:23- Octonots and algae eaters, - to the HQ.
0:06:32 > 0:06:35- Octonots, our mission - is to save the coral reef.
0:06:36 > 0:06:40- First, we have to show the damsel - fish that the coral reef is sick.
0:06:40 > 0:06:44- We'll steal some algae - from the damsel fish...
0:06:44 > 0:06:48- ..and use it as bait - to lead them to the sick coral.
0:06:48 > 0:06:53- So the damsel fish will see - that the coral reef is in trouble.
0:06:53 > 0:06:56- This algae - is guarded by the damsel fish.
0:06:57 > 0:07:01- And each damsel fish - has his own patch of algae.
0:07:01 > 0:07:06- If we take algae from the - boss's patch, he'll chase after us.
0:07:06 > 0:07:12- Aye. But look at all those patches. - How do we know which one is his?
0:07:12 > 0:07:14- Already on it, Harri.
0:07:14 > 0:07:18- Dela and I have been working - on the damsel fish-cam.
0:07:18 > 0:07:21- It looks just like a damsel fish!
0:07:22 > 0:07:25- I'll use it to find - the boss's algae patch.
0:07:32 > 0:07:35- This camera has damsel-fish vision.
0:07:35 > 0:07:38- The boss has one big spot - on his head.
0:07:38 > 0:07:40- Come on, show yourself.
0:07:40 > 0:07:43- There he is - and there's his patch of algae.
0:07:44 > 0:07:49- The boss is surrounded by damsel - fish. How do we get past them?
0:07:49 > 0:07:53- That's where Pete, Pigyn - and Prys come in.
0:07:56 > 0:08:00- Each of you has a skill you can use - to distract the damsel fish.
0:08:00 > 0:08:01- Squirting sand?
0:08:02 > 0:08:03- Speed.
0:08:03 > 0:08:07- I'm thinking. Give me a minute. - Is it my spikes?
0:08:07 > 0:08:12- Yes, it's your spikes. While you - keep the other damsel fish busy...
0:08:13 > 0:08:16- ..Pegwn drops Harri - into the boss's algae patch.
0:08:16 > 0:08:18- Then I take the algae...
0:08:18 > 0:08:21- And we lead the boss - to the sick coral.
0:08:21 > 0:08:25- Alright, everybody. - Operation Algae Lift begins now.
0:08:26 > 0:08:28- Pigyn, you're on.
0:08:31 > 0:08:34- Oh, this algae looks delicious!
0:08:34 > 0:08:37- Come and get me.
0:08:42 > 0:08:46- Oi, you! And you! And you! - Keep off the algae.
0:08:46 > 0:08:48- Huh?
0:08:48 > 0:08:51- Just dropping in for lunch. - Let's go, Pegwn.
0:08:51 > 0:08:54- No, that's my algae!
0:08:55 > 0:08:57- Damsel fish, follow that cat.
0:08:57 > 0:09:00- Faster, Pegwn! Hit the turbo button.
0:09:00 > 0:09:03- I've never driven - a getaway sub before.
0:09:08 > 0:09:11- He took the bait. We're on our way.
0:09:11 > 0:09:13- Very good, Harri.
0:09:13 > 0:09:17- Pegwn, there's a big rock coming up. - Fake right then go left.
0:09:18 > 0:09:19- Thanks, captain.
0:09:22 > 0:09:24- Whoa!
0:09:27 > 0:09:31- Captain! - More damsel fish are coming at us.
0:09:31 > 0:09:33- Shiver me whiskers.
0:09:35 > 0:09:36- Pull up fast, pull up.
0:09:39 > 0:09:40- Yiaow!
0:09:40 > 0:09:42- Yiaow!- - Don't lose them.
0:09:43 > 0:09:47- That was absolutely... brilliant!
0:09:47 > 0:09:49- Woo-hoo!
0:09:52 > 0:09:56- We've got you right - where we want you.
0:09:56 > 0:10:00- We've got you right - where we want you. Take a look.
0:10:00 > 0:10:02- Here.
0:10:02 > 0:10:03- And here.
0:10:04 > 0:10:04- And here.
0:10:05 > 0:10:05- And here.
0:10:06 > 0:10:10- The coral looks bad. - What's it got to do with me?
0:10:10 > 0:10:12- If you keep - all the algae for yourself...
0:10:13 > 0:10:15- ..the coral reef - will disappear for ever.
0:10:16 > 0:10:20- Hold on. - No more reef, no more algae.
0:10:20 > 0:10:27- But it can get well again if we let - the other fish eat the extra algae.
0:10:29 > 0:10:30- Exactly.
0:10:30 > 0:10:35- Er... Alright. - You've got yourself a deal.
0:10:36 > 0:10:39- Who's ready - for a spicy algae burger?
0:10:41 > 0:10:43- This is great, Gwyddno.
0:10:58 > 0:10:58- .
