0:01:22 > 0:01:25- Can't you tell the difference - between us?
0:01:26 > 0:01:28- We're students, not experts.
0:01:33 > 0:01:38- Why does Ethel stroke her fur - all the time, like this?
0:01:38 > 0:01:41- She needs air under her fur - to keep warm.
0:01:41 > 0:01:45- If her fur is dirty, - the air can't penetrate it.
0:01:45 > 0:01:47- And I end up feeling cold.
0:01:50 > 0:01:55- The best way to keep warm - is rolling. Try it, it's fun.
0:01:58 > 0:02:00- Like this.
0:02:01 > 0:02:03- That does look like fun.
0:02:04 > 0:02:06- Roll, Oli, roll.
0:02:19 > 0:02:21- BEEPING
0:02:21 > 0:02:22- It's Dyf.

0:02:25 > 0:02:26- It'll be here soon.
0:02:27 > 0:02:29- The sky is black - near the lighthouse.
0:02:31 > 0:02:34- Come back to the station right away.
0:02:34 > 0:02:36- OK, sir, we'll be there now.
0:02:36 > 0:02:37- OK, sir, we'll be there now.- - Over and out.
0:02:37 > 0:02:39- Does it mean our fun is over?
0:02:40 > 0:02:41- Sorry, Morfudd.
0:02:42 > 0:02:44- Don't worry.

0:04:21 > 0:04:22- Oli.
0:04:28 > 0:04:30- Where's he going at such a hurry?
0:04:33 > 0:04:37- Beth, stop. What's going on? - I waited for you for ages.
0:04:38 > 0:04:40- There's been an oil spill.
0:04:41 > 0:04:44- Oil spill? This is disastrous.
0:04:44 > 0:04:47- Awen's on her way - with equipment to help us.
0:04:47 > 0:04:49- Let's head for the dock.
0:04:52 > 0:04:54- Wait.
0:04:56 > 0:05:00- You can't clean the oil. - It's too dangerous for a seal.
0:05:00 > 0:05:02- You're right.
0:05:04 > 0:05:07- Sid might need help - with the sea creatures.
0:05:08 > 0:05:10- OK, I'll help Sid.
0:05:20 > 0:05:22- Faster, you sea snail!

0:05:29 > 0:05:31- Wait, Sid.
0:05:34 > 0:05:36- Morfudd, I don't have time to play.
0:05:36 > 0:05:39- I know. - You're helping with the oil spill.
0:05:40 > 0:05:43- I'm taking this equipment - to Dyf and Wena...
0:05:44 > 0:05:47- ..to clean the creatures - caught up in the oil.
0:05:47 > 0:05:49- I'll help you.
0:05:51 > 0:05:54- There's no need. - Everything's under control.
0:05:57 > 0:05:59- I really want to help.
0:06:04 > 0:06:07- Thanks for bringing - the equipment out so quickly.
0:06:08 > 0:06:10- We have to stop the oil.
0:06:11 > 0:06:15- We're all trying to get - the situation under control.
0:06:17 > 0:06:19- Can I help you unload?
0:06:19 > 0:06:23- Your fins weren't designed - to unload.
0:06:23 > 0:06:26- There must be something I can do.
0:06:26 > 0:06:28- I don't think so.
0:06:28 > 0:06:30- Oil is dangerous for seals.
0:06:31 > 0:06:36- I know that. I can't stand around - watching everyone else helping.
0:06:36 > 0:06:41- A lot of creatures like you - have to stay away from the oil.
0:06:41 > 0:06:45- Birds, seals and sea otters.
0:06:45 > 0:06:48- Sea otters? Has anyone seen Ethel?
0:06:48 > 0:06:50- Who's Ethel?
0:06:50 > 0:06:52- Who's Ethel?- - She's a sea otter.
0:06:52 > 0:06:54- She was supposed to meet Morfudd.
0:06:55 > 0:06:57- I hope she wasn't - caught in the storm.
0:06:58 > 0:07:00- I'll look for her.
0:07:03 > 0:07:05- Look at all that oil.
0:07:05 > 0:07:07- Can this equipment...
0:07:07 > 0:07:10- ..clean all the mess up?
0:07:10 > 0:07:13- This equipment, - which looks like sausages...
0:07:14 > 0:07:16- ..is supposed - to stop the oil spreading...
0:07:16 > 0:07:19- ..before the skimmer - collects it together.
0:07:20 > 0:07:22- Let's give it a go.
0:07:22 > 0:07:24- Awen's here to help us.
0:07:24 > 0:07:26- Ready? Off we go.
0:07:27 > 0:07:31- Well done. Keep the oil between - the beams. A little to the left.
0:07:31 > 0:07:33- It's working, Beth.
0:07:34 > 0:07:35- Great.
0:07:35 > 0:07:37- Hooray!

0:07:44 > 0:07:46- Ethel!
0:07:46 > 0:07:48- I've looked everywhere for her.
0:07:49 > 0:07:52- Morfudd? Over here.
0:07:52 > 0:07:56- Ethel? - Oh, no, you're covered in oil.
0:07:56 > 0:08:03- Yes. I was caught - in the middle of the oil slick.
0:08:04 > 0:08:07- You're shivering. - You need to be cleaned.
0:08:07 > 0:08:09- Come over to Dyf the diver.
0:08:10 > 0:08:14- No, we'll get caught up in the oil - if we go that way.
0:08:14 > 0:08:17- The oil is dangerous for you, too.
0:08:18 > 0:08:20- OK then, I'll look for Sid.
0:08:20 > 0:08:24- He'll take you to Dyf the diver.
0:08:24 > 0:08:26- You'll be clean in no time.
0:08:26 > 0:08:28- Thanks, Morfudd.
0:08:28 > 0:08:30- I'll be back now.
0:08:33 > 0:08:36- Where was she? - Crannog and I looked everywhere.
0:08:37 > 0:08:39- We couldn't see her.
0:08:39 > 0:08:42- There are sea creatures everywhere. - They're hiding.
0:08:43 > 0:08:45- Why?
0:08:45 > 0:08:49- They're scared. - They're hiding around Black Rock.
0:08:49 > 0:08:51- I have to help them.
0:08:51 > 0:08:55- I can't. If I go too close - to the rocks, I might get damaged.
0:08:56 > 0:08:57- I'll go.
0:08:57 > 0:09:00- I can go right up to the rocks.
0:09:00 > 0:09:02- OK, off you go.
0:09:06 > 0:09:09- Come out. Don't be scared.
0:09:11 > 0:09:13- Come on. Everything's OK.
0:09:13 > 0:09:15- Sid is kind. Really, he is.
0:09:15 > 0:09:17- Climb on board.
0:09:17 > 0:09:21- Welcome on board. - Fill the back seats first.
0:09:21 > 0:09:25- I'll take these - back to Dyf and Wena.
