0:00:00 > 0:00:00- .
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 Midnight Zone.
0:00:53 > 0:00:54- Spanner.
0:00:58 > 0:00:59- Screwdriver.
0:01:03 > 0:01:04- Carrot.
0:01:07 > 0:01:09- Thank you, Vegimals.
0:01:19 > 0:01:21- Is Sub-1 ready to go?
0:01:21 > 0:01:24- Yes indeed, Cap.
0:01:24 > 0:01:26- Sound the Octoalert.
0:01:28 > 0:01:30- To the launch bay.
0:01:40 > 0:01:45- Today, our mission - is to travel to the seabed...
0:01:45 > 0:01:48- ..to add a new page - to Cregynnog's book.
0:01:48 > 0:01:52- This is the unfinished guide - to the Midnight Zone.
0:01:52 > 0:01:56- Midnight Zone? - It sounds frightening.
0:01:56 > 0:02:01- Yes, it is. The Midnight Zone is - so deep, the sun never shines there.
0:02:01 > 0:02:06- I describe the creatures which live - in the Midnight Zone in the book.
0:02:07 > 0:02:10- A limpet, a tubeworm, a vent fish.
0:02:10 > 0:02:14- I don't have anything - on the final pages.
0:02:14 > 0:02:16- Our work is filling the pages...
0:02:17 > 0:02:21- ..with information - about a creature never seen before.
0:02:21 > 0:02:25- Since it's so dark there, I've - added an extra light to the sub.
0:02:26 > 0:02:29- If it's flashing, - the power is about to run out.
0:02:29 > 0:02:31- You must return at once.
0:02:32 > 0:02:36- Cregynnog, Pegwn, Harri, - wear your deep seas diving gear.
0:02:37 > 0:02:40- Ready? Open the Octohatch, Ira.
0:02:41 > 0:02:43- Right away, Cap.
0:02:56 > 0:02:58- It's not dark yet.
0:02:59 > 0:03:01- We're within range of the sun.
0:03:13 > 0:03:15- Are we there? It's getting darker.
0:03:15 > 0:03:19- No. This is the Twilight Zone.
0:03:19 > 0:03:23- The Midnight Zone - is further down and darker.
0:03:23 > 0:03:27- Further down and darker. Gulp!
0:03:30 > 0:03:33- Octonots, - we've reached the Midnight Zone.
0:03:35 > 0:03:36- It is dark down here.
0:03:40 > 0:03:42- Let's switch - the underwater lights on.
0:03:49 > 0:03:51- It's eerily silent.
0:03:53 > 0:03:54- What's that sound?
0:03:55 > 0:03:59- Just the engine. - It's the sound it always makes.
0:03:59 > 0:04:01- WHIRRING
0:04:01 > 0:04:03- How about that?
0:04:03 > 0:04:06- There's something hot ahead of us.
0:04:07 > 0:04:09- Shivering whiskers.
0:04:09 > 0:04:11- What's that?
0:04:11 > 0:04:13- Smoke?
0:04:17 > 0:04:18- Whoa!
0:04:22 > 0:04:24- Jumping jellyfish.
0:04:25 > 0:04:27- Hydrothermal vents.
0:04:27 > 0:04:30- What's a hydrothermal vent?
0:04:30 > 0:04:35- An underwater volcano. - The water at the top is very hot.
0:04:35 > 0:04:36- Helmets, everyone.
0:04:37 > 0:04:41- The perfect place to find a creature - never before seen.
0:04:43 > 0:04:45- Octonots, let's go for it.
0:04:45 > 0:04:47- Yaw!
0:04:48 > 0:04:49- Ready.
0:04:55 > 0:04:56- Captain.
0:04:57 > 0:04:59- Have you found something?
0:05:04 > 0:05:07- A limpet, but that's nothing new.
0:05:08 > 0:05:10- Tubeworms only live - in the Midnight Zone.
0:05:11 > 0:05:13- Very nice but they're nothing new.
0:05:13 > 0:05:14- Very nice but they're nothing new.- - Huh?
0:05:16 > 0:05:18- Over here.
0:05:21 > 0:05:23- It's large, dark and...
0:05:24 > 0:05:26- ..and, and...
0:05:26 > 0:05:28- They're only rocks.
0:05:28 > 0:05:30- Sorry, Cregynnog.
0:05:31 > 0:05:35- That's a vent fish. - He's nothing new, I'm afraid.
0:05:36 > 0:05:37- We'll carry on looking.
0:05:45 > 0:05:47- Cregynnog, what are these holes?
0:05:49 > 0:05:54- Interesting. I've seen a rock - with holes once before.
0:05:54 > 0:05:56- I have no idea - what the holes were for.
0:05:57 > 0:05:59- Let's cut a sample of the rock.
0:05:59 > 0:06:01- I'll go and get the drill.
0:06:05 > 0:06:07- Let me try it.
0:06:10 > 0:06:12- Thanks, but I'll do it myself.
0:06:25 > 0:06:27- Oh, no. I've broken it.
0:06:31 > 0:06:34- Never mind. - I can see inside it properly now.
0:06:34 > 0:06:37- There might be something inside it.
0:06:37 > 0:06:41- I can't see anything. - Where's the other piece?
0:06:41 > 0:06:42- I have it.
0:06:43 > 0:06:45- Octonots, Sub-1's power is low.
0:06:45 > 0:06:47- We should go.
0:06:48 > 0:06:50- I haven't found a new creature.
0:06:50 > 0:06:52- I haven't found a new creature.- - We'll come back another time.
0:06:52 > 0:06:54- Back to the sub.
0:07:00 > 0:07:04- Did you find a creature - no one's seen before?
0:07:04 > 0:07:05- Uh, no.
0:07:06 > 0:07:08- My pages are still blank.
0:07:09 > 0:07:14- Pity we didn't find - something big and horrible.
0:07:14 > 0:07:17- We found a rock with holes in it.
0:07:22 > 0:07:23- Something's alive in here.
0:07:40 > 0:07:41- Where am I?
0:07:41 > 0:07:43- You're on the Octopod.
0:07:46 > 0:07:47- My house is broken.
0:07:47 > 0:07:49- My house is broken.- - Don't worry.
0:07:49 > 0:07:55- We'll fix it before you can say - bunch of munchy crunchy carrots.
0:07:55 > 0:07:58- OK, but hurry up. I'm freezing.
0:07:58 > 0:08:00- The light's hurting my eyes.
0:08:01 > 0:08:04- You live in the Midnight Zone - where it's always dark.
0:08:05 > 0:08:07- The hydrothermal vents are very hot.
0:08:07 > 0:08:09- The Octopod must seem strange.
0:08:09 > 0:08:11- The Octopod must seem strange.- - I want to go home.
0:08:12 > 0:08:14- Ira will fix your house...
0:08:14 > 0:08:18- ..and then we'll take you back - to the Midnight Zone.
0:08:18 > 0:08:22- Until then, we'll do our best - to make your stay comfortable.
0:08:27 > 0:08:31- How's that? - Warm enough? Dark enough?
0:08:31 > 0:08:34- Well, for now, thank you.
0:08:34 > 0:08:37- We must discover - how the tunnels link together.
0:08:38 > 0:08:40- Give this a try.
0:08:49 > 0:08:50- No.
0:08:50 > 0:08:52- OK, I'll try again.
0:08:53 > 0:08:55- No.
0:08:55 > 0:08:56- Hold on.
0:08:58 > 0:09:00- That should do.
0:09:05 > 0:09:08- No, no, no. - The holes aren't in the right place.
0:09:08 > 0:09:10- I hit my head.
0:09:11 > 0:09:13- Don't worry. We'll persevere.
0:09:15 > 0:09:19- We've been looking at the problem - from the outside.
0:09:19 > 0:09:22- We need to look at it - from the inside.
0:09:23 > 0:09:25- Dela could help.
0:09:26 > 0:09:31- With this miniature camera, we can - see your tunnels from the inside.
0:09:32 > 0:09:34- I call it worm's view.
0:09:34 > 0:09:35- Ready?
0:09:35 > 0:09:37- Ready.
0:09:41 > 0:09:42- No way through.
0:09:42 > 0:09:45- The holes are still - in the wrong place.
0:09:45 > 0:09:48- The other way is blocked.
0:10:01 > 0:10:03- It's perfect.
0:10:03 > 0:10:04- Incredible.
0:10:05 > 0:10:08- I'll use some limpet glue - to hold it together.
0:10:10 > 0:10:12- As good as new.
0:10:12 > 0:10:14- I want a picture. Say seaweed.
0:10:15 > 0:10:16- Seaweed.
0:10:17 > 0:10:20- We'll take you home, - where it's nice and dark.
0:10:21 > 0:10:23- I can't wait!
0:10:26 > 0:10:29- Octonots, - call down any time you want.
0:10:29 > 0:10:33- Pegwn, we have a new friend - in the Midnight Zone.
0:10:33 > 0:10:37- It might be dark here but I'm - not scared of this place any more.
0:10:37 > 0:10:41- And you have your own page - in my book.
0:10:41 > 0:10:43- Good!
0:10:58 > 0:10:58- .
