0:00:56 > 0:00:59- Captain to Ira. - Ready for progress report.
0:00:59 > 0:01:01- Go ahead, Cap.
0:01:02 > 0:01:06- It's looking good down here. - The legs are attached.
0:01:11 > 0:01:12- And the door is secure.
0:01:12 > 0:01:14- And the door is secure.- - Thanks, Captain.
0:01:20 > 0:01:25- Halt! Ah, the last two computers - are in place on the upper level.
0:01:33 > 0:01:37- Thanks, Professor. It looks like - we're ready. What do you think?
0:01:38 > 0:01:40- It's time to put all the parts...
0:01:41 > 0:01:44- ..of our brand new - deep sea Octo-lab together.
0:01:45 > 0:01:50- Octonots and vegimals, - prepare for full assembly.
0:01:56 > 0:01:58- This is it, mateys.
0:01:58 > 0:01:59- Ready?
0:01:59 > 0:02:01- Ready?- - Ready.
0:02:01 > 0:02:03- Activate full assembly.
0:02:03 > 0:02:06- Activate full assembly.- - You got it, Cap!
0:02:17 > 0:02:20- Full assembly complete.
0:02:20 > 0:02:21- Hooray!
0:02:21 > 0:02:23- Hooray!- - Fantastic.
0:02:25 > 0:02:29- Octonots, - welcome to the deep sea Octo-lab.
0:02:29 > 0:02:31- Wow!
0:02:31 > 0:02:33- Wow!- - Very nice.
0:02:36 > 0:02:38- Yowsers!
0:02:38 > 0:02:41- Our mission - is to take the deep sea Octo-lab...
0:02:42 > 0:02:45- ..all the way down - to the bottom of the Mariana Trench.
0:02:46 > 0:02:50- The Mariana Trench is the deepest, - darkest place on Earth.
0:02:50 > 0:02:54- Once we're set up Dela and Cregynog - will stay for a few weeks...
0:02:54 > 0:02:57- ..while we return to the Octo-pod.
0:02:57 > 0:03:01- We're leaving them in - the deepest, darkest place on Earth?
0:03:02 > 0:03:03- Absolutely.
0:03:03 > 0:03:08- We'll be the first scientists to - live and study down in the trench.
0:03:08 > 0:03:12- We'll take pictures of parts - of the sea that no-one has seen.
0:03:13 > 0:03:16- And discover new creatures. - I hope!
0:03:16 > 0:03:21- In a place so dangerous that even - pirates have never gone there.
0:03:22 > 0:03:26- That sounds like a big job - for only two Octonots.
0:03:27 > 0:03:30- Don't worry, Pegwn. Ira and I - have invented some helpers.
0:03:31 > 0:03:33- Meet the Octo-bots.
0:03:35 > 0:03:37- The Octo-bots will help us.
0:03:38 > 0:03:41- They have video cameras for eyes - so we can see what they see.
0:03:42 > 0:03:45- They can collect rocks - from the sea floor.
0:03:50 > 0:03:53- Gwyddno wants to show you - his invention.
0:03:58 > 0:04:02- The Vegi-bot is programmed to - provide all the comforts of home.
0:04:03 > 0:04:04- Thank you, Vegi-bot.
0:04:04 > 0:04:08- Er, no more kelp cakes for me, - thank you.
0:04:09 > 0:04:10- Ow!
0:04:15 > 0:04:16- Oh, dear.
0:04:20 > 0:04:22- Sorry about that.
0:04:22 > 0:04:27- I'm still working out some glitches - but everything else is ready to go.
0:04:27 > 0:04:30- Let's hook the Octo-lab - up to the Octo-pod...
0:04:30 > 0:04:33- ..and head for the Mariana Trench.
0:04:45 > 0:04:47- That should fix the problem.
0:04:48 > 0:04:50- Let's test it out, Gwyddno.
0:04:51 > 0:04:54- I'd like one kelp cake please, - Vegi-bot.
0:04:59 > 0:05:01- Thank you. Perfect.
0:05:03 > 0:05:05- Vegi-bot test successful.
0:05:06 > 0:05:07- Very good.
0:05:07 > 0:05:11- We're getting close - to the Mariana Trench.
0:05:11 > 0:05:13- Dela, it's time to go downwards.
0:05:13 > 0:05:15- Dela, it's time to go downwards.- - I'm on it, Captain.
0:05:15 > 0:05:18- The deeper we go, - the darker it gets.
0:05:19 > 0:05:23- Prepare to travel into the - total darkness of the Midnight Zone.
0:05:46 > 0:05:51- We pass through these sea mountains - to get down to the trench.
0:05:51 > 0:05:53- Dela, let's take it slow.
0:06:00 > 0:06:03- These sea mountains are tall.
0:06:03 > 0:06:07- Yes, some of them are taller - than any mountain on dry land.
0:06:11 > 0:06:14- There it is - the Mariana Trench.
0:06:14 > 0:06:19- It looks like a massive - bottomless pit of darkness.
0:06:20 > 0:06:24- Yes. The trench is much too deep - to see to the bottom from up here.
0:06:24 > 0:06:29- How do we know where to put the - Octo-lab if we can't see the bottom?
0:06:29 > 0:06:33- We'll have to go down and look. - Harri, Cregynog, you're with me.
0:06:48 > 0:06:52- Time to get out of the Gup - and head for the bottom.
0:07:01 > 0:07:03- We've made it to the bottom.
0:07:03 > 0:07:05- Whoa!
0:07:05 > 0:07:09- It's a field of hydrothermal vents - but something's wrong.
0:07:12 > 0:07:15- Isn't there supposed to be - steam coming out?
0:07:15 > 0:07:17- Look, some of them have crumbled.
0:07:18 > 0:07:23- Hydrothermal vents are hot with - lots of animals living round them...
0:07:23 > 0:07:25- ..but they don't last for ever.
0:07:26 > 0:07:29- These vents have gone cold - and fallen apart.
0:07:29 > 0:07:32- And there's not a creature stirring.
0:07:35 > 0:07:36- I'm in position.
0:07:38 > 0:07:39- What's the report?
0:07:40 > 0:07:44- You know I can't see very well - so give me a moment to work it out.
0:07:45 > 0:07:50- Three, yes, - three different shiny creatures.
0:07:52 > 0:07:54- One of them has a long tentacle.
0:07:55 > 0:07:56- Do they seem hungry?
0:07:56 > 0:07:58- Do they seem hungry?- - Are they coming to eat us?
0:08:00 > 0:08:04- Everybody, snap to it. - Hold your positions.
0:08:06 > 0:08:09- Hush, hush, quiet!
0:08:09 > 0:08:13- This area is fascinating but we - can't put the deep sea Octo-lab...
0:08:13 > 0:08:16- ..on top of these crumbling vents.
0:08:16 > 0:08:18- Let's look for a better place.
0:08:21 > 0:08:24- They're gone. Coast is clear!
0:08:26 > 0:08:28- We're safe for now.
0:08:29 > 0:08:33- I'm afraid we can't live around - these hydrothermal vents any more.
0:08:34 > 0:08:35- They're too cold for us.
0:08:36 > 0:08:38- We'll march across this trench...
0:08:38 > 0:08:42- ..until we find a new - hydrothermal vent to call home.
0:08:42 > 0:08:44- Somewhere nice and hot.
0:08:44 > 0:08:47- With lots of steam - and gas bubbling up.
0:08:48 > 0:08:53- A place where baby tube worms - can grow up to be giant tube worms.
0:08:53 > 0:08:55- A-ha, that's the spirit!
0:08:55 > 0:08:59- Now then. Come on, find a partner - and don't forget the clam.
0:08:59 > 0:09:04- Climb aboard, old friend. - Sideways, march!
0:09:04 > 0:09:06- # We live in the midnight zone
0:09:07 > 0:09:08- # We live in the midnight zone
0:09:09 > 0:09:10- # In the dark, but not alone
0:09:10 > 0:09:13- # In the dark, but not alone- - # In the dark, but not alone #
0:09:14 > 0:09:16- Hmm. This area's nice and flat.
0:09:16 > 0:09:20- I think we've found the perfect - place for the deep sea Octo-lab.
0:09:21 > 0:09:23- Agreed. Captain to Dela.
0:09:24 > 0:09:25- Dela here, Captain.
0:09:25 > 0:09:27- Dela here, Captain.- - We've found our spot.
0:09:27 > 0:09:29- Move the Octo-pod into position.
0:09:32 > 0:09:34- The Octo-pod is in position.
0:09:34 > 0:09:36- The Octo-pod is in position.- - Very good, Dela.
0:09:36 > 0:09:40- The trench is too narrow so the - Gup-C will take it part of the way.
0:09:41 > 0:09:43- Ready, Ira?
0:09:43 > 0:09:45- Octonots, let's do this.
0:09:52 > 0:09:54- On my way down, Cap.
0:09:57 > 0:09:59- There she is, mateys.
0:09:59 > 0:10:00- There she is, mateys.- - Alright, Ira.
0:10:00 > 0:10:05- On my signal, release the cable and - let the Octo-lab fall into place.
0:10:05 > 0:10:07- You got it, Cap.
0:10:07 > 0:10:10- You got it, Cap.- - Ready, steady... drop!
0:10:15 > 0:10:19- Octonots, - the deep sea Octo-lab has landed.
0:10:20 > 0:10:22- Let's turn on the lights - and get to work.
0:10:53 > 0:10:55- I'm not nervous - about being down here any more.
0:10:56 > 0:10:58- The Octo-lab feels completely safe.
0:10:58 > 0:11:00- The Octo-lab feels completely safe.- - Oh, it is safe, Pegwn.
0:11:00 > 0:11:05- It's cold and dark out there but - we've got plenty of light and heat.
0:11:06 > 0:11:11- And I put the whole thing on legs - so it'll just bounce around
0:11:11 > 0:11:14- ..without breaking a thing - if we get hit by tremors.
0:11:15 > 0:11:19- We're down so deep that there's only - a thin layer of the sea floor...
0:11:20 > 0:11:24- ..between us and the - hot, melted rock inside the Earth.
0:11:25 > 0:11:29- When pieces of the sea floor move - around on top of the melted rock...
0:11:29 > 0:11:32- ..they bump into each other - and we get tremors.
0:11:33 > 0:11:37- Special equipment shows us whether - or not there are tremors close by.
0:11:38 > 0:11:40- Let's turn it on.
0:11:42 > 0:11:45- Everything's calm and steady - for now. No tremors.
0:11:46 > 0:11:49- Phew! I hope it stays that way.
0:11:50 > 0:11:53- We've collected - fantastic rock samples.
0:11:54 > 0:11:56- The Octo-bots are working well.
0:11:58 > 0:12:02- Uh-oh, something's coming. - Come on, boys. Time to roll.
0:12:20 > 0:12:22- Where are we?
0:12:22 > 0:12:24- Where are we?- - I don't know.
0:12:34 > 0:12:36- I smell food.
0:12:36 > 0:12:39- I smell food.- - Smells good. Let's roll!
0:12:42 > 0:12:43- This way.
0:12:49 > 0:12:51- Keep them coming.
0:12:51 > 0:12:55- Delicious. - I could eat a million of them.
0:12:56 > 0:12:58- # We live in the midnight zone
0:12:58 > 0:13:00- # We live in the midnight zone- - # We live in the midnight zone
0:13:00 > 0:13:02- # In the dark, but not alone
0:13:02 > 0:13:04- # In the dark, but not alone- - # In the dark, but not alone #
0:13:04 > 0:13:04- # In the dark, but not alone
0:13:04 > 0:13:05- Everybody, halt!
0:13:06 > 0:13:11- I feel heat! - And it's coming from this thing.
0:13:12 > 0:13:15- A nice warm-up for cold claws.
0:13:16 > 0:13:18- Snap to it. Sideways... climb!
0:13:19 > 0:13:24- Left, left, left, - left, left, left, left...
0:13:26 > 0:13:29- It's even warmer in here. Come on.
0:13:31 > 0:13:34- Uh-oh. We've got a situation.
0:13:34 > 0:13:36- I'm stuck!
0:13:36 > 0:13:38- Chain of claws.
0:13:41 > 0:13:44- One, two, three... pull!
0:13:47 > 0:13:48- Again, pull!
0:13:51 > 0:13:52- Almost!
0:13:52 > 0:13:58- Alright, let's make this one count. - One, two, three... pull!
0:14:08 > 0:14:10- Sound the Octo-alert.
0:14:11 > 0:14:13- To the lower deck.
0:14:22 > 0:14:25- Octonots, we've lost all power - to the Octo-lab.
0:14:26 > 0:14:28- I need to check the power generator.
0:14:28 > 0:14:30- I need to check the power generator.- - We'll light your way.
0:14:31 > 0:14:33- I have to open it up.
0:14:33 > 0:14:38- There's no telling who - or what could be hiding in there.
0:14:40 > 0:14:44- Oh, something's coming. - Hide, everyone!
0:14:46 > 0:14:49- Oh, me, oh, my! A wire's been cut.
0:14:49 > 0:14:51- But who would do that?
0:14:51 > 0:14:53- But who would do that?- - BELCH
0:14:53 > 0:14:58- That's the roar of a wire-cutting - monster if ever I heard one.
0:14:59 > 0:15:01- Yaw! Giant bugs!
0:15:02 > 0:15:04- Easy, now.
0:15:04 > 0:15:06- Easy, now.- - No sudden moves.
0:15:06 > 0:15:10- Oh, no worries. - We can't move at alright now.
0:15:10 > 0:15:12- Oh, no. Are you alright?
0:15:13 > 0:15:17- Oh, we're fine. - Just really, really full.
0:15:18 > 0:15:23- It's tough for us giant isopods - to find food down, so when we do...
0:15:23 > 0:15:28- We eat and eat and eat - until we can't eat any more.
0:15:28 > 0:15:34- Sometimes, we eat so much that we're - too stuffed to move for a while. Oh!
0:15:34 > 0:15:37- Giant isopods? Fascinating.
0:15:37 > 0:15:42- Most isopods are tiny but down - this deep, the isopods are giants.
0:15:42 > 0:15:45- But if you didn't cut the wire, - then who did?
0:15:46 > 0:15:47- Look behind you.
0:15:49 > 0:15:51- Stop!
0:15:51 > 0:15:52- Stop!- - Uh-oh!
0:15:52 > 0:15:53- Please don't hurt us!
0:15:54 > 0:15:56- Don't worry, we won't hurt you.
0:15:56 > 0:16:00- Oh, I'm sorry, - I cut your wire by accident.
0:16:00 > 0:16:02- What were you doing - in our generator?
0:16:03 > 0:16:06- It was nice and warm in there - and we like warm.
0:16:06 > 0:16:10- We're looking for a nice, hot - hydrothermal vent to call home.
0:16:10 > 0:16:15- We'll help you find a new home, - but we need to get our power back.
0:16:16 > 0:16:18- I'll just fix up this wire.
0:16:21 > 0:16:24- That ought to do it. - OK, I'm going to turn it back on.
0:16:34 > 0:16:39- Uh-oh, power surge caused - the Octo-bots to short-circuit.
0:16:39 > 0:16:41- They're out of control.
0:16:52 > 0:16:56- Take the Octo-buggy. - Go after Gwyddno and the Vegi-bot.
0:16:56 > 0:16:57- Aye-aye!
0:16:59 > 0:17:02- Cregynog, go that way - and Dela, go that way.
0:17:02 > 0:17:06- I'll go this way. - Let's catch those Octo-bots!
0:17:09 > 0:17:12- Ah, there you are.
0:17:12 > 0:17:15- Hmm, let me help you with that.
0:17:17 > 0:17:22- I'm heading back to the Octo-lab - with the runaway Octo-bot.
0:17:22 > 0:17:24- He's picked up a rock - for your collection.
0:17:24 > 0:17:30- I've found a type of sea cucumber - I've never seen before.
0:17:32 > 0:17:36- And this one is recording - some beautiful, glowing sea stars.
0:17:37 > 0:17:40- Harri? Have you caught up - with the Vegi-bot?
0:17:43 > 0:17:44- Not yet, Captain.
0:17:55 > 0:18:00- Yargh! We're on the edge - of a lake of boiling hot gloop.
0:18:00 > 0:18:02- It sounds fascinating.
0:18:02 > 0:18:05- It looks dangerous.
0:18:05 > 0:18:08- Harri, - turn on the Octo-buggy camera.
0:18:08 > 0:18:13- Aye. Octo-buggy camera on.
0:18:14 > 0:18:16- Jumping jellyfish!
0:18:17 > 0:18:20- It's a lake of boiling hot sulphur. - Incredibly rare.
0:18:21 > 0:18:22- Can you get a sample?
0:18:23 > 0:18:24- Aye, matey.
0:18:26 > 0:18:28- Just be careful not to fall in.
0:18:32 > 0:18:36- Got it. Yar, the Vegi-bot!
0:18:46 > 0:18:47- Yagh!
0:18:47 > 0:18:50- Shiver me whiskers, - there's mud flying everywhere!
0:18:51 > 0:18:53- Mud volcanoes - amazing!
0:18:54 > 0:18:55- This is great, Harri.
0:18:55 > 0:18:59- Videos of underwater mud volcanoes - is really rare.
0:19:12 > 0:19:13- We'll get him, matey!
0:19:18 > 0:19:22- I'll get as close as I can - and you nab him with the grabber.
0:19:31 > 0:19:32- Now, Gwyddno!
0:19:35 > 0:19:37- We did it, matey!
0:19:38 > 0:19:39- We have the Vegi-bot.
0:19:40 > 0:19:41- Good work, Harri.
0:19:42 > 0:19:44- Captain, look - a tremor.
0:19:44 > 0:19:45- Captain, look - a tremor.- - It's getting bigger.
0:19:46 > 0:19:50- Harri, be careful. A big tremor - is about to shake things up.
0:19:50 > 0:19:52- Brace yourselves, everyone.
0:19:56 > 0:19:59- Yargh, agh!
0:20:00 > 0:20:02- Hang on, Gwyddno!
0:20:05 > 0:20:07- We'll go the other way.
0:20:17 > 0:20:20- Whoa, can't stop now.
0:20:21 > 0:20:26- Looks like there's only one thing - to do - go faster!
0:20:33 > 0:20:36- Ha-ha! We made it.
0:20:36 > 0:20:39- Ha-ha! We made it.- - Harri, Gwyddno - are you alright?
0:20:39 > 0:20:41- Aye-aye, Captain. We're fine.
0:20:41 > 0:20:45- We just went flying over - a river of hot, melted rock.
0:20:45 > 0:20:47- It's incredible.
0:20:47 > 0:20:51- You've found the perfect home - for our hydrothermal vent friends.
0:20:52 > 0:20:53- I did?
0:20:53 > 0:20:54- I did?- - Yes!
