0:01:13 > 0:01:15- I love documentaries.
0:01:15 > 0:01:18- The sea - has a spellbinding environment.
0:01:18 > 0:01:21- Do you know why the sea roars?
0:01:21 > 0:01:25- You'd roar too - if you had crabs under your bed.
0:01:25 > 0:01:27- SHE BREAKS WIND
0:01:28 > 0:01:29- BEEPING
0:01:31 > 0:01:33- Oops, sorry.

0:01:47 > 0:01:48- Look at me, Beth.
0:01:48 > 0:01:50- You're so clever.
0:01:53 > 0:01:55- Hiya, Dyfrig.
0:01:55 > 0:01:57- Hello, Oli. Hiya, Beth.
0:02:03 > 0:02:07- Oli and Beth, research submarines - from the underwater laboratory...
0:02:08 > 0:02:09- ..reporting for duty.
0:02:09 > 0:02:11- I have a task for you.
0:02:12 > 0:02:13- OK, sir.
0:02:17 > 0:02:22- I want you to cut these large stones - and place them in the skip.
0:02:22 > 0:02:25- You want us to move stones.
0:02:26 > 0:02:29- They were left here by a waste ship.
0:02:29 > 0:02:32- They could create some problems.
0:02:35 > 0:02:38- I know, Oli, it's not much fun - but it's an important job.
0:02:41 > 0:02:44- It shouldn't take you long. Enjoy.
0:02:50 > 0:02:53- I can't believe he wants us - to break stones.
0:02:53 > 0:03:00- He said it was important work. Let's - pretend someone's stuck under one.
0:03:00 > 0:03:02- We have to rescue them.
0:03:02 > 0:03:05- Yeah, Oli and Beth save the day.
0:03:05 > 0:03:07- Don't worry, little creature.
0:03:09 > 0:03:11- We'll rescue you.
0:03:14 > 0:03:19- Whoa! Did you see that fish? - We have to get it in our programme.
0:03:19 > 0:03:20- Hold on.
0:03:20 > 0:03:22- Hold on.- - It's disappearing.
0:03:22 > 0:03:26- We're not here to film fish. - We have to work.
0:03:26 > 0:03:27- That can wait.
0:03:27 > 0:03:31- That can wait.- - Dyfrig didn't ask us to film fish.
0:03:31 > 0:03:34- Beth, we might see a fish - no-one's seen before.
0:03:35 > 0:03:37- You'll be the first to film it.
0:03:38 > 0:03:42- It might be named after you. - The Beth fish.
0:03:42 > 0:03:45- Come on, let's follow the Beth fish.
0:03:57 > 0:03:59- We-hey, cool.
0:04:13 > 0:04:15- Eurgh.
0:04:20 > 0:04:22- Yuck.
0:04:24 > 0:04:26- What's this dirt?
0:04:28 > 0:04:31- I think it's mechanic mud.
0:04:34 > 0:04:36- Look.
0:04:36 > 0:04:38- Wow. What's that?
0:04:43 > 0:04:46- Look at the state of you.
0:04:46 > 0:04:48- Come here, children.
0:04:49 > 0:04:52- We're in a bit of a hurry.
0:04:52 > 0:04:54- Really now.
0:04:54 > 0:04:59- Isn't it incredible? There are - gas bubbles all over the place.
0:04:59 > 0:05:01- We've really got to go.
0:05:04 > 0:05:08- Remember, - gas always rises to the surface.
0:05:10 > 0:05:12- Look at that dirty fish.
0:05:12 > 0:05:16- Don't worry, - I'll clean it up in no time.
0:05:17 > 0:05:19- 'Bye!
0:05:19 > 0:05:21- Goodbye.
0:05:24 > 0:05:27- I hope we find that little fish.
0:05:28 > 0:05:30- We're bound to find it.
0:05:30 > 0:05:31- # Off you go, squid
0:05:32 > 0:05:35- # Off you go, off you go #
0:05:36 > 0:05:38- Warden.
0:05:38 > 0:05:41- Well, hello, friends.
0:05:41 > 0:05:46- Have you heard this one? Why do - sharks only swim in saltwater?
0:05:46 > 0:05:49- I don't know. Why do they?
0:05:50 > 0:05:54- Because pepperwater - would make them sneeze!
0:05:54 > 0:05:56- Good joke.
0:06:00 > 0:06:03- Warden, - have you seen a strange fish?
0:06:03 > 0:06:06- Yes indeed. It went that way.
0:06:06 > 0:06:08- Thanks, warden.
0:06:09 > 0:06:11- Hey, a big whale and inky-poo.
0:06:18 > 0:06:21- I don't think we'll find it.
0:06:21 > 0:06:23- Let's get back to the stones.
0:06:23 > 0:06:27- Not yet, it must be here somewhere.
0:06:27 > 0:06:29- Where are we?
0:06:29 > 0:06:31- Searching for a rare fish.
0:06:35 > 0:06:37- It's very deep here.
0:06:38 > 0:06:40- Look, there it is.
0:06:45 > 0:06:48- There's no turning back now. - We have to follow it.
0:06:48 > 0:06:50- It's gone.
0:06:50 > 0:06:52- It's gone.- - Come on, Beth. Look at this.
0:06:54 > 0:06:58- Do you see where the seaweed's torn? - Our fish must have done it.
0:06:59 > 0:07:01- You think it's in here?
0:07:02 > 0:07:03- Yes, it's here.
0:07:03 > 0:07:05- Yes, it's here.- - I'm not entering the cave.
0:07:06 > 0:07:10- It's dark and yucky. - I don't care how rare the fish is.
0:07:10 > 0:07:12- Come on, please.
0:07:12 > 0:07:15- No, I won't. - You go on if you want to.
0:07:15 > 0:07:18- OK, I will.
0:07:18 > 0:07:21- Wait, let me tie this seaweed - to your tail.
0:07:21 > 0:07:26- If you get lost, you can follow - the seaweed back to me, OK?
0:07:27 > 0:07:30- Uh, OK. Thanks, Beth.
0:07:30 > 0:07:32- Be careful, Oli.
0:07:52 > 0:07:56- Oli, wait for me.
0:08:07 > 0:08:09- Wonderful waves! There it is.
0:08:10 > 0:08:13- # Squid, - come back to the pen, come back #
0:08:14 > 0:08:18- Poo-ee! It's hard work - gathering all the squid together.
0:08:18 > 0:08:22- Some seaweed would be perfect - to tie them up.
0:08:22 > 0:08:26- That's just the thing.
0:08:27 > 0:08:30- Oli, are you down here?
0:08:31 > 0:08:33- Oli, is that you? I hope so.
0:08:33 > 0:08:36- Whoa, Beth?
0:08:36 > 0:08:41- Oli, I'm so glad to see you. - I wasn't really scared, though.
0:08:41 > 0:08:43- Of course not.
0:08:43 > 0:08:44- Of course not.- - Did you find it?
0:08:45 > 0:08:47- Yes. I have some great footage.
0:08:47 > 0:08:50- Great. Can we go now?
0:08:50 > 0:08:54- Yes. - Thanks to you and your great idea.
0:08:54 > 0:08:56- Whoa!
0:08:59 > 0:09:02- Um, I'm sorry, Beth.
0:09:02 > 0:09:04- This is all my fault.
0:09:04 > 0:09:07- We should never have entered - this silly cave.
0:09:08 > 0:09:11- You're right there...
0:09:11 > 0:09:15- ..but we have to get out of here - and I have an idea.
0:09:15 > 0:09:18- Do you know what we were told - about bubbles?
0:09:18 > 0:09:20- They're full of gas.
0:09:20 > 0:09:23- SHE BREAKS WIND
0:09:23 > 0:09:25- Gas always rises to the surface.
0:09:25 > 0:09:28- We have to follow the bubble.
0:09:28 > 0:09:30- Back to the surface.
0:09:31 > 0:09:33- Beth, you're incredible.
0:09:55 > 0:09:57- That was great, submarines.
0:09:57 > 0:10:00- I've never seen footage - like that before.
0:10:01 > 0:10:04- He insisted on getting footage - of the fish.
0:10:04 > 0:10:09- I couldn't have done it without - Beth. She got us out of the cave.
0:10:10 > 0:10:13- I'm proud of you. - Well done, good work.
0:10:13 > 0:10:19- However, your task today was moving - the stones. Have you finished?
0:10:20 > 0:10:21- No.
0:10:21 > 0:10:23- No, they haven't.
0:10:23 > 0:10:26- You'd better finish your work.
0:10:26 > 0:10:29- Off you go to finish your work.
0:10:29 > 0:10:30- Dyf...
0:10:31 > 0:10:35- As a successful underwater - submarine, you have to work hard...
0:10:36 > 0:10:38- ..even when you don't want to.
0:10:39 > 0:10:40- Yes, work hard.
0:10:41 > 0:10:44- Yes, sir, I understand.
0:10:44 > 0:10:46- Sid, you can help them.
0:10:49 > 0:10:53- By the way, your programme - was great. Very good.
0:10:53 > 0:10:56- Cool! Ha!
0:11:26 > 0:11:26- .
