0:00:05 > 0:00:08Barnacles!
0:00:08 > 0:00:09Kwazii!
0:00:09 > 0:00:11Peso!
0:00:38 > 0:00:41- Explore!- Rescue!- Protect!
0:00:41 > 0:00:43Octonauts!
0:00:55 > 0:00:57Here we are - the lava tubes.
0:00:57 > 0:00:59Great. Let's get started.
0:01:01 > 0:01:03HE SIGHS
0:01:03 > 0:01:04I don't see any lava.
0:01:04 > 0:01:09That's because it's all underground. The hot lava flows under the sea bed.
0:01:09 > 0:01:12When it dries it makes caves like these.
0:01:12 > 0:01:14They are called lava tubes.
0:01:14 > 0:01:17Inside, it can get very hot.
0:01:17 > 0:01:18HE GULPS
0:01:18 > 0:01:20How hot?
0:01:20 > 0:01:22That's what we're going to find out. Shellington?
0:01:22 > 0:01:27We'll use these special thermometers to see how hot they are,
0:01:27 > 0:01:31but going inside a lava tube can be dangerous
0:01:31 > 0:01:34so we'll check from the outside - like this.
0:01:36 > 0:01:38THERMOMETER BEEPS
0:01:38 > 0:01:42This one's very, very hot.
0:01:42 > 0:01:43Fascinating.
0:01:43 > 0:01:47I've used a thermometer lots of times to take sick creatures' temperatures.
0:01:47 > 0:01:49This shouldn't be too hard.
0:01:49 > 0:01:51Just be careful everyone and watch out for loose boulders
0:01:51 > 0:01:53and steam vents.
0:01:56 > 0:01:58THERMOMETER BEEPS
0:02:02 > 0:02:03There.
0:02:03 > 0:02:04THERMOMETER BEEPS
0:02:06 > 0:02:07Yar! Yarr! Yargh!
0:02:07 > 0:02:08Yowl!
0:02:11 > 0:02:12PESO PANTS AND GASPS
0:02:12 > 0:02:14Steady, steady...
0:02:14 > 0:02:16THERMOMETER BEEPS
0:02:16 > 0:02:17Ahh!
0:02:18 > 0:02:19STEAM HISSES
0:02:21 > 0:02:22Wah! Ah! Oh...
0:02:24 > 0:02:29Oh! Oh, this would be a lot easier if I were bigger and faster.
0:02:29 > 0:02:31Hey, buddy, you all right?
0:02:31 > 0:02:32Who said that?
0:02:32 > 0:02:34I did, down here.
0:02:34 > 0:02:35Huh?
0:02:36 > 0:02:37Ooh?!
0:02:37 > 0:02:39The name's Frank. What's yours?
0:02:39 > 0:02:41Um...Peso.
0:02:41 > 0:02:44Peso, we heard you shout. Is everything all right?
0:02:44 > 0:02:49I, um, I'm fine, but I found a rock and its name is Frank.
0:02:49 > 0:02:52(I think the heat might be getting to him, Captain.)
0:02:52 > 0:02:54Hiya, fellas! I'm Frank!
0:02:54 > 0:02:55THEY GASP
0:02:55 > 0:02:58But...how?
0:02:58 > 0:02:59Ah-ha!
0:02:59 > 0:03:00Fascinating.
0:03:00 > 0:03:01Well?
0:03:01 > 0:03:02What do you see?
0:03:02 > 0:03:06Frank isn't a rock, he's a water bear!
0:03:06 > 0:03:08How you doing?
0:03:08 > 0:03:12Water bears are tiny creatures that live all over the world.
0:03:12 > 0:03:14That's right!
0:03:14 > 0:03:19Oceans, forests, snowy mountains - we live everywhere.
0:03:19 > 0:03:22My uncle Gary even went into outer space.
0:03:22 > 0:03:24But you're so small.
0:03:24 > 0:03:26We may be small, but we're tough.
0:03:26 > 0:03:30You got to be tough to live around here with all the lava tubes
0:03:30 > 0:03:32and big rocks and steam...
0:03:32 > 0:03:33STEAM VENT HISSES
0:03:33 > 0:03:35Frank!
0:03:35 > 0:03:36The lava tube!
0:03:36 > 0:03:37THEY GRUNT
0:03:37 > 0:03:40Time to sound the Octo-alert.
0:03:40 > 0:03:41Octonauts, to the HQ.
0:03:44 > 0:03:45SIRENS WAIL
0:03:51 > 0:03:56Octonauts, a teeny, tiny water bear has fallen into a hot lava tube
0:03:56 > 0:03:57and we've got to get him out.
0:03:57 > 0:04:01Captain, exploring lava tubes is extremely dangerous.
0:04:01 > 0:04:04You never know when one might suddenly erupt.
0:04:04 > 0:04:06Then we'll need some way to look inside
0:04:06 > 0:04:08and see what we're dealing with.
0:04:08 > 0:04:10- Dashi? - Already on it, Captain.
0:04:14 > 0:04:18This Rover Cam will show us the inside of the lava tube.
0:04:18 > 0:04:19ROVER BEEPS
0:04:24 > 0:04:26Looks hot!
0:04:26 > 0:04:28I just hope Frank is all right in there.
0:04:28 > 0:04:29THEY WHIMPER
0:04:31 > 0:04:32Dashi, over there.
0:04:35 > 0:04:36It's Frank's rock.
0:04:36 > 0:04:38Can you pick it up, Dashi?
0:04:38 > 0:04:39I'll try.
0:04:43 > 0:04:44Easy. Easy.
0:04:46 > 0:04:47THEY WHIMPER
0:04:48 > 0:04:51The heat must be damaging the Rover Cam,
0:04:51 > 0:04:52but I almost have it.
0:04:54 > 0:04:55Oh! Lost it!
0:04:55 > 0:04:56Oh, no!
0:04:56 > 0:04:57THEY GASP
0:04:57 > 0:04:59It's too hot in there.
0:04:59 > 0:05:02Then we'll just have to go in and find Frank ourselves.
0:05:02 > 0:05:07You can't just swim into a lava tube, it's as hot as an oven in there.
0:05:07 > 0:05:09That's why I brought these -
0:05:09 > 0:05:10heat-proof diving suits.
0:05:10 > 0:05:12These will protect you from the heat
0:05:12 > 0:05:14and the Octo-goggles will help you see Frank.
0:05:19 > 0:05:23If we follow the Rover Cam's cable, it should lead us to Frank's rock.
0:05:23 > 0:05:24RUMBLING, THEY GASP
0:05:24 > 0:05:26That doesn't sound good.
0:05:26 > 0:05:30Captain, there's a lot of unusual lava movement
0:05:30 > 0:05:33beneath the cave. It could erupt at any moment.
0:05:33 > 0:05:35You'd better find Frank quickly.
0:05:35 > 0:05:37Oh! Uh-oh! Head down.
0:05:39 > 0:05:43Oh! I thought the whole cave was going to collapse.
0:05:43 > 0:05:44Ahh! What's...?
0:05:44 > 0:05:47I can't see.
0:05:47 > 0:05:50Look - the Rover Cam! It's right here in front of us.
0:05:50 > 0:05:51HE STRAINS
0:05:51 > 0:05:53Uh, Kwazii...
0:05:55 > 0:05:57Oh, yeah. Ha-ha!
0:05:57 > 0:05:59These Octo-goggles really do make things look bigger.
0:06:03 > 0:06:05Look! There's Frank's rock.
0:06:05 > 0:06:06Frank!
0:06:09 > 0:06:10Oh, he's not there.
0:06:10 > 0:06:12Oh, no!
0:06:12 > 0:06:14Peso, buddy, over here.
0:06:16 > 0:06:18Frank! Are you all right?
0:06:18 > 0:06:19We're here to...
0:06:19 > 0:06:21CHATTERING
0:06:21 > 0:06:22..rescue you.
0:06:22 > 0:06:25Hey, it's pretty great down here, ain't it?
0:06:25 > 0:06:28I met a lot of nice folks - there's Jo...
0:06:28 > 0:06:29Hi there!
0:06:29 > 0:06:30- ..and Eddie...- How you doing?
0:06:30 > 0:06:32- ..and Laverne...- Hello!

0:06:34 > 0:06:35Uh, howdy!
0:06:35 > 0:06:38You mean...water bears can actually live down here?
0:06:39 > 0:06:41We sure can!
0:06:41 > 0:06:43But don't you little mateys get hot?
0:06:43 > 0:06:46I told you we was tough! A little heat don't bother us.
0:06:46 > 0:06:49DASHI: 'Captain, the lava tube is about to erupt.'
0:06:49 > 0:06:51We're on our way out, Dashi.
0:06:51 > 0:06:54You water bears should come with us.
0:06:54 > 0:06:56No, we're good. We don't mind the heat.
0:06:56 > 0:06:58Yeah, we like it hot.
0:06:58 > 0:07:01- The hotter the better. - No, we're happy where we are.
0:07:01 > 0:07:04But the whole cave is about to fill up with lava.
0:07:04 > 0:07:07No problem. We'll be just fine.
0:07:07 > 0:07:08Hold on. Did you say lava?
0:07:08 > 0:07:09THEY GASP
0:07:09 > 0:07:11RUN FOR YOUR LIVES!
0:07:11 > 0:07:13THEY PANIC AND GROAN

0:07:28 > 0:07:29Oh, nice day out!
0:07:31 > 0:07:33Is it just me or is it getting hotter in here?
0:07:33 > 0:07:34Yiaow!
0:07:35 > 0:07:37Lava! We have to hurry!
0:07:39 > 0:07:42HE PANTS This would be a lot easier...
0:07:42 > 0:07:44if I were...bigger and faster.
0:07:46 > 0:07:49Come on, Peso! My uncle Gary always says,
0:07:49 > 0:07:52"It doesn't matter how big or fast you are,
0:07:52 > 0:07:53"you just got to be tough.
0:07:53 > 0:07:55FRANK YAWNS
0:07:55 > 0:07:58How can you be sleepy at a time like this?
0:07:58 > 0:08:01When water bears get really hot,
0:08:01 > 0:08:04we got to sleep until it's safe to wake up.
0:08:04 > 0:08:06YAWNING
0:08:06 > 0:08:08- SLEEPILY: - See what I mean?

0:08:30 > 0:08:34- He was just here.- Yo, Frankie! - Frank, where are you?
0:08:34 > 0:08:35He must have fallen off.
0:08:37 > 0:08:42- He's not here.- But that means, he's somewhere back there.
0:08:42 > 0:08:44On the other side of those rocks!
0:08:44 > 0:08:45We can't leave him behind!
0:08:45 > 0:08:49Don't worry, Peso, we'll find a way to get through that rock pile.
