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!
0:00:45 > 0:00:47- The Octonots - and the Hungry Pilot Fish.
0:00:51 > 0:00:57- Octonots, our task is to see which - sharks we can find in the reef.
0:00:57 > 0:01:00- I can't wait to study them - first hand.
0:01:01 > 0:01:03- I don't want to get too close.
0:01:03 > 0:01:05- Sharks are dangerous.
0:01:05 > 0:01:09- Yes, that's why - I'm in such a hurry to...
0:01:09 > 0:01:11- Clean the dirt off the subs?
0:01:11 > 0:01:12- What?
0:01:12 > 0:01:15- What?- - It's your turn to clean the subs.
0:01:16 > 0:01:20- What's the hurry, Captain? - They're not dirty.
0:01:20 > 0:01:25- They're covered in dirt. They don't - work properly if they're dirty.
0:01:25 > 0:01:30- OK then. I'll sort them out - but I'd rather swim with the sharks.
0:01:30 > 0:01:33- What about Sub-1?
0:01:33 > 0:01:35- That's dirty, too.
0:01:35 > 0:01:38- It'll be OK for one journey.
0:01:41 > 0:01:43- Uh, maybe not.
0:01:46 > 0:01:49- A-ha! Here we go. - Open the Octohatch.
0:01:50 > 0:01:52- Right away, Cap.
0:01:58 > 0:02:01- OK then. I'll do it.
0:02:03 > 0:02:05- Hey, Harri, do you want a game?
0:02:05 > 0:02:08- Hey, Harri, do you want a game?- - After a game of table tennis!
0:02:22 > 0:02:25- Look. A pilot fish.
0:02:26 > 0:02:27- But no sharks yet.
0:02:28 > 0:02:32- We'll travel further down. - We might have more luck there.
0:02:51 > 0:02:55- Some would say this was easier - for you, Wythennyn.
0:02:57 > 0:03:00- You're the winner. Well done, Harri.
0:03:01 > 0:03:04- I'd better go back - and clean the subs.
0:03:06 > 0:03:09- Well, maybe one more game.
0:03:09 > 0:03:11- Against you all.
0:03:11 > 0:03:13- Come on then.
0:03:21 > 0:03:22- No sharks here.
0:03:22 > 0:03:24- Nothing here.
0:03:27 > 0:03:30- Try the front window.
0:03:32 > 0:03:34- Wondrous waves.
0:03:35 > 0:03:36- Sh... sh... sh...
0:03:36 > 0:03:38- Sh... sh... sh...- - A white-tipped shark.
0:03:38 > 0:03:40- Can you see the ends of its fins?
0:03:40 > 0:03:45- Look at those teeth. They haven't - seen a toothbrush in a while.
0:03:46 > 0:03:48- Whoa!
0:03:51 > 0:03:56- What's it trying to do? Captain, I - think it's been tempted by the sub.
0:03:57 > 0:03:59- It could hurt itself... and us.
0:03:59 > 0:04:01- Hold on, Octonots.
0:04:22 > 0:04:25- Uh-oh. - There's dirt in the propeller.
0:04:25 > 0:04:27- Hold on tight.
0:04:30 > 0:04:34- OK, my hearties, next point wins.
0:04:45 > 0:04:47- Pink Bart!
0:04:50 > 0:04:51- That's Sub-1.
0:04:52 > 0:04:55- It's having a great adventure - chasing a shark.
0:04:55 > 0:04:59- They're not chasing a shark. - The shark's chasing them!
0:05:10 > 0:05:13- We can't get rid of him. - Sound the Octoalert.
0:05:15 > 0:05:17- Octonots, to your stations.
0:05:26 > 0:05:29- Octonots, - we need to get away from the shark.
0:05:30 > 0:05:31- Open the Octohatch.
0:05:32 > 0:05:33- Right away.
0:05:33 > 0:05:35- Hold on tight.
0:05:39 > 0:05:40- Ready, Ira?
0:05:42 > 0:05:43- Close it.
0:05:49 > 0:05:50- Great work.
0:05:51 > 0:05:54- Incredible. - I wonder why the shark chased us?
0:05:54 > 0:05:57- You looked like a tasty meal to him.
0:05:57 > 0:06:01- No, that's not why. - Sharks don't eat boats.
0:06:01 > 0:06:03- He could've had me for lunch.
0:06:03 > 0:06:07- That's what happens - when you drive a dirty sub.
0:06:07 > 0:06:09- How's the cleaning coming along?
0:06:09 > 0:06:12- How's the cleaning coming along?- - I haven't started... finished yet.
0:06:13 > 0:06:14- Back to work.
0:06:24 > 0:06:29- What? Who cleaned Sub-1?
0:06:31 > 0:06:32- Me.
0:06:32 > 0:06:34- Hello. How did you get in here?
0:06:34 > 0:06:36- Hello. How did you get in here?- - I followed the sub. I want more.
0:06:37 > 0:06:39- You like cleaning?
0:06:39 > 0:06:44- I'm a pilot fish. I eat dirt. - Clean and eat, eat and clean.
0:06:47 > 0:06:49- Tuck in!
0:06:57 > 0:06:58- Look at that!
0:07:00 > 0:07:02- Delicious.
0:07:12 > 0:07:16- Good work. - These subs were never this clean.
0:07:16 > 0:07:22- As I always say, if a job's worth - doing, it's worth doing yourself.
0:07:22 > 0:07:27- How did you do it so quickly, - and on your own, too?
0:07:27 > 0:07:29- Uh, yeah.
0:07:29 > 0:07:31- I didn't do it all myself.
0:07:32 > 0:07:34- No?
0:07:34 > 0:07:38- Harri, I'm still hungry. - Eat and clean, clean and eat.
0:07:39 > 0:07:43- Here's my cleaning partner, - the pilot fish.
0:07:43 > 0:07:46- Hello. - Did you follow us from the reef?
0:07:47 > 0:07:50- The reef? Yes. I was looking - for something to eat.
0:07:51 > 0:07:53- What do you usually clean?
0:07:53 > 0:07:54- Sharks.
0:07:55 > 0:07:57- Isn't that dangerous?
0:07:58 > 0:08:01- No, sharks and pilot fish - help each other.
0:08:01 > 0:08:05- I clean its teeth and it scares - away fish that want to eat me.
0:08:06 > 0:08:09- If I could find a shark, - I could feast forever more.
0:08:09 > 0:08:13- There was a shark in the reef. - Its teeth were dirty.
0:08:14 > 0:08:16- Did he want them cleaned?
0:08:16 > 0:08:18- A shark with dirty teeth?
0:08:18 > 0:08:20- Do you know where it is?
0:08:21 > 0:08:23- I'm sure we could find it.
0:08:24 > 0:08:27- Octonots, our friend helped us - clean the subs.
0:08:27 > 0:08:30- We'll help him find that shark.
0:08:30 > 0:08:33- Pegwn, Harri, come with me.
0:08:36 > 0:08:40- I'll look after that pilot fish - if the shark has a temper.
0:08:40 > 0:08:44- I'll look after you two - if you're hurt.
0:08:44 > 0:08:46- Eat and clean, clean and eat.
0:08:46 > 0:08:48- Let's do this.
0:08:49 > 0:08:50- Open the Octohatch.
0:08:51 > 0:08:53- Right away.
0:08:59 > 0:09:02- This is better than cleaning.
0:09:09 > 0:09:13- There's no sign - of the shark anywhere.
0:09:14 > 0:09:17- What if we don't find him?
0:09:21 > 0:09:22- Sh... sh...
0:09:22 > 0:09:24- Shark!
0:09:26 > 0:09:28- Its teeth are still dirty.
0:09:39 > 0:09:42- Time to eat and clean, - clean and eat.
0:09:44 > 0:09:46- Was this really a good idea?
0:09:47 > 0:09:48- Open wide.
0:09:55 > 0:09:57- Phew. He's fine.
0:09:59 > 0:10:01- Better already.
0:10:01 > 0:10:04- You're far better - than any toothbrush.
0:10:04 > 0:10:06- My pleasure.
0:10:07 > 0:10:11- The shark was trying to use - the sub as a toothbrush.
0:10:11 > 0:10:14- Now, he has a pilot fish - to do the work for him.
0:10:14 > 0:10:20- I have a shark to look after me. - I have to go - clean and eat!
0:10:20 > 0:10:21- You know how it is.
0:10:22 > 0:10:24- Thank you, Octonots.
0:10:24 > 0:10:25- Cheerio!
0:10:25 > 0:10:30- We'll miss him. I'll have to clean - all the subs myself next time.
0:10:30 > 0:10:33- Oh, I'll help you.
0:10:33 > 0:10:34- Will you?
0:10:34 > 0:10:36- Will you?- - Eating and cleaning.
0:10:36 > 0:10:39- Cleaning and eating. - You know how it is.
0:10:39 > 0:10:41- THEY ALL LAUGH
0:10:58 > 0:10:58- .
