0:00:52 > 0:00:57- Everyone, prepare for ice landing - in three, two, one.
0:01:00 > 0:01:01- Ready to get started?
0:01:01 > 0:01:02- Ready to get started?- - I am.
0:01:03 > 0:01:05- I can't wait to see what lives here.
0:01:05 > 0:01:09- Harri, you and Pegwn can help - Cregynog watch for creatures.
0:01:09 > 0:01:13- Brrr! You'd have to be nuts - to live here in Antarctica.
0:01:15 > 0:01:17- Can anyone see any creatures?
0:01:17 > 0:01:19- Can anyone see any creatures?- - Not yet.
0:01:19 > 0:01:22- It's all just white, white, white...
0:01:22 > 0:01:25- And red! Shiver me whiskers!
0:01:25 > 0:01:28- There's something red, - straight ahead!
0:01:28 > 0:01:30- Jumping jellyfish!
0:01:30 > 0:01:33- Jumping jellyfish!- - A waterfall made out of ice.
0:01:33 > 0:01:35- But why is the ice red?
0:01:36 > 0:01:40- I don't know. I've never seen - anything like it before.
0:01:40 > 0:01:42- Fire up the Ice Spy.
0:01:43 > 0:01:47- The Ice Spy will show us - what's under the ice.
0:01:47 > 0:01:50- Avast, there's a lake down there!
0:01:50 > 0:01:53- That must be where the red ice - is coming from.
0:01:53 > 0:01:58- The ice is thick. The lake must have - been under it for millions of years.
0:01:58 > 0:02:01- Who knows what creatures - live down there.
0:02:01 > 0:02:07- Let's take a look. Pegwn, detach - Octo-sled and activate Ice Drill.
0:02:11 > 0:02:13- Here we go.
0:02:20 > 0:02:24- Captain, the ice is too thick. - The drill can't take it.
0:02:24 > 0:02:28- We're not giving up yet. - Send more heat to the drill.
0:02:28 > 0:02:30- OK, Captain.
0:02:32 > 0:02:33- Almost there.
0:02:36 > 0:02:38- The drill is broken!
0:02:40 > 0:02:43- Aye, but we've reached the lake.
0:02:43 > 0:02:48- The drill will have to wait. - Cregynog, are you ready to head...?
0:02:48 > 0:02:50- That's the spirit, matey!
0:02:51 > 0:02:53- I can't wait to see - what's down there!
0:02:53 > 0:02:55- Take it slowly, Cregynog.
0:02:56 > 0:03:00- One careless move out here - and we could be in trouble.
0:03:00 > 0:03:01- Secret lake, here I come!
0:03:04 > 0:03:10- Amazing. No-one has ever seen - this place before.
0:03:10 > 0:03:13- Have you any idea - why the water's red, Cregynog?
0:03:14 > 0:03:17- The water contains - tiny bits of rusty iron.
0:03:17 > 0:03:21- That's why it's so red, - there's rust in the water.
0:03:21 > 0:03:26- Careful. It would be easy - to get lost down here. Stay close.
0:03:27 > 0:03:30- Ah, the water is also very salty.
0:03:30 > 0:03:32- And cold.
0:03:32 > 0:03:33- And dark.
0:03:33 > 0:03:37- I don't think any creatures - could survive down here.
0:03:37 > 0:03:40- Sorry, Cregynog, - we'd better get back to GUP-S.
0:03:41 > 0:03:44- I might as well - take a water sample first.
0:03:48 > 0:03:52- Cheer up. We did find - this amazing red waterfall.
0:03:52 > 0:03:54- And we learned what makes it red.
0:03:54 > 0:03:58- And we learned what makes it red.- - We're all shipshape and toasty warm.
0:03:58 > 0:04:02- I would've loved to have found a - creature down there. Even just one.
0:04:03 > 0:04:08- It's been a long day. - We'll rest here before we head home.
0:04:09 > 0:04:11- But it's still light outside.
0:04:11 > 0:04:14- In Antarctica, it doesn't - get dark at this time of year.
0:04:15 > 0:04:17- Not even at night.
0:04:20 > 0:04:23- How am I supposed to sleep - if it's not dark?
0:04:26 > 0:04:27- A-ha!
0:04:34 > 0:04:36- Hello!
0:04:36 > 0:04:37- Hello!- - Huh?
0:04:39 > 0:04:40- Hello!
0:04:40 > 0:04:45- I must be hearing things. - Maybe I need some sleep?
0:04:45 > 0:04:48- Hello! Over here!
0:04:49 > 0:04:52- Huh? Ah! Jumping jellyfish!
0:04:53 > 0:04:56- No, not jellyfish - microbe. - Name's Mervyn.
0:04:57 > 0:04:59- I'm a teeny, tiny microbe.
0:04:59 > 0:05:03- I'm so small, you can't see me - with just your eyes.
0:05:03 > 0:05:05- Nice to meet you!
0:05:05 > 0:05:07- Where did you come from?
0:05:07 > 0:05:11- From the red lake under the ice, - of course. That's my home.
0:05:12 > 0:05:17- I didn't think anything could live - down there, it's so cold and dark.
0:05:17 > 0:05:22- But it's just right for me. I don't - mind that it's cold and dark at all.
0:05:22 > 0:05:25- What about you? - Is this where you live?
0:05:25 > 0:05:27- No, this is the GUP-S.
0:05:27 > 0:05:30- My name is Cregynog. I'm an Octonot.
0:05:31 > 0:05:32- An Octo-what?
0:05:32 > 0:05:37- I want to hear all about it. - But, oh, dear!
0:05:37 > 0:05:38- What's wrong?
0:05:39 > 0:05:42- It's just a little bit warm - and bright up here.
0:05:42 > 0:05:45- I think you'd better take me - back down to the lake.
0:05:45 > 0:05:49- Already? But I haven't introduced - you to the others!
0:05:49 > 0:05:53- Oh, hurry, Cregynog - - I'm boiling hot in here!
0:05:53 > 0:05:56- Don't worry, Mervyn, - I'll get you home.
0:05:57 > 0:06:00- This ice hole feels smaller - than last time.
0:06:01 > 0:06:04- Keep going, - I'm feeling cooler already.
0:06:05 > 0:06:06- Aaarrggghhh!
0:06:09 > 0:06:11- That's more like it. Thank you.
0:06:12 > 0:06:16- Come on, - there's so much I want to show you.
0:06:16 > 0:06:19- I suppose it wouldn't hurt - to have a quick look around.
0:06:20 > 0:06:24- Great! Follow me! - You have to meet the others.
0:06:24 > 0:06:26- Others?
0:06:27 > 0:06:28- A little further.
0:06:30 > 0:06:32- A little further.
0:06:32 > 0:06:34- Jumping jellyfish!
0:06:35 > 0:06:38- Cregynog, - meet the other microbes.
0:06:38 > 0:06:42- There's so many of you! But how - do you find enough food down here?
0:06:43 > 0:06:45- We don't need food.
0:06:45 > 0:06:49- We get all the energy we need - from the rust in the water.
0:06:50 > 0:06:53- Yep, we eat rust, man.
0:06:53 > 0:06:55- That's Jac.
0:06:55 > 0:06:58- This is Siwan. And say hi to Alys.
0:06:58 > 0:07:00- Hi!
0:07:01 > 0:07:03- Hello, pleased to meet you.
0:07:03 > 0:07:06- I can't wait - to tell the others about you.
0:07:06 > 0:07:10- Oh... If I can find my way back out - of here. Was the ice hole this way?
0:07:11 > 0:07:12- Or was it that way?
0:07:12 > 0:07:15- Oh! That's not good.
0:07:16 > 0:07:17- Mayday, Mayday!
0:07:17 > 0:07:21- Cregynog to GUP-S, come in, please!
0:07:21 > 0:07:25- Help! Mayday! Come in! - Cregynog to GUP-S, come in, please!
0:07:26 > 0:07:28- Where am I?
0:07:28 > 0:07:31- Captain Cwrwgl, do you read me?
0:07:31 > 0:07:33- Cregynog, where are you?
0:07:33 > 0:07:37- Captain! I'm in the lake... - Tiny creatures... Captain, help!
0:07:40 > 0:07:42- Harri and Pegwn, to the ice hole.
0:07:51 > 0:07:54- Cregynog is stranded - down in the ice lake.
0:07:54 > 0:07:55- We have to rescue him.
0:07:56 > 0:07:57- It's getting colder.
0:07:58 > 0:08:00- If the hole freezes, he'll be stuck.
0:08:01 > 0:08:04- There's no time to lose. - Harri, with me.
0:08:04 > 0:08:09- Pegwn, you stay here and keep an - eye on the ice hole. Let's do this!
0:08:12 > 0:08:17- This is taking forever, Captain. - I think I know a faster way down.
0:08:17 > 0:08:20- Agreed. On three - one, two...
0:08:21 > 0:08:22- Three! Whooooo!
0:08:27 > 0:08:29- No sign of him, Captain.
0:08:29 > 0:08:32- Cregynog! Cregynog!
0:08:32 > 0:08:34- Captain Cwrwgl!
0:08:34 > 0:08:36- Did you hear that?
0:08:36 > 0:08:40- It's just the cold - playing tricks with your mind.
0:08:40 > 0:08:42- This way! Come here!
0:08:42 > 0:08:45- There it is again. - What was it Cregynog said?
0:08:45 > 0:08:47- Something about tiny creatures.
0:08:47 > 0:08:50- Follow those voices!
0:08:51 > 0:08:53- Cregynog?
0:08:53 > 0:08:54- Cregynog?- - Oh, dear.
0:08:54 > 0:08:57- Cregynog! Cregynog.
0:08:57 > 0:09:00- Captain! How did you find me?
0:09:00 > 0:09:02- We showed them the way.
0:09:02 > 0:09:06- That's Mervyn. He lives - down here with all his friends.
0:09:06 > 0:09:09- The cold, dark water - doesn't bother them at all.
0:09:10 > 0:09:11- Hey-hey!
0:09:11 > 0:09:13- Hey-hey!- - I'll be a sea monkey's uncle!
0:09:13 > 0:09:18- Captain, come in! - The ice hole is closing fast. Hurry!
0:09:18 > 0:09:20- We'd better get out of here.
0:09:20 > 0:09:25- Already? This is the most excitement - we've had in a million years!
0:09:26 > 0:09:27- Maybe two.
0:09:27 > 0:09:28- Thanks for your help.
0:09:28 > 0:09:31- Thanks for your help.- - We'll come back and visit sometime.
0:09:31 > 0:09:33- Bye! See you soon!
0:09:33 > 0:09:36- Now let's eat some more rust, man.
0:09:36 > 0:09:40- Quick, before the hole - freezes over completely.
0:09:51 > 0:09:53- Pegwn, lower the rescue line!
0:09:56 > 0:09:59- Right, Pegwn - pull us up.
0:09:59 > 0:10:00- Hold on tight!
0:10:06 > 0:10:07- Flappity flippers!
0:10:12 > 0:10:14- Pegwn, hit the brake.
0:10:14 > 0:10:16- Pegwn, hit the brake.- - Brake? Brake? Brake!
0:10:16 > 0:10:17- Brake!
0:10:21 > 0:10:23- Nice driving, Pegwn.
0:10:23 > 0:10:25- Thank you, Captain.
0:10:25 > 0:10:30- I still can't believe you found - living creatures down there.
0:10:30 > 0:10:33- How many microbes were down there?
0:10:33 > 0:10:34- How many microbes were down there?- - Well, let's see.
0:10:35 > 0:10:37- Carry the two, multiply by five...
0:10:37 > 0:10:39- About 10,000,362.
0:10:39 > 0:10:44- Oh, no, wait - I forgot about - that big one with the squiggly tail.
0:10:59 > 0:10:59- .
