0:00:02 > 0:00:05- SIREN WAILS - 'Octonauts, to your stations!'
0:00:05 > 0:00:07Barnacles!
0:00:07 > 0:00:09Kwazii!
0:00:09 > 0:00:10Peso!
0:00:37 > 0:00:40- Explore!- Rescue!- Protect!
0:00:40 > 0:00:42Octonauts!
0:00:51 > 0:00:53Remind me again, Shellington,
0:00:53 > 0:00:57what do you call those creatures you're looking for?
0:00:57 > 0:00:58Remipedes, Captain.
0:00:58 > 0:01:03They're very unusual creatures, and this area is crawling with them.
0:01:03 > 0:01:04Before you head out,
0:01:04 > 0:01:08let me just show you how to drive the GUP-D one more time.
0:01:08 > 0:01:11I'll be fine, Captain. I've seen the GUP-D in action.
0:01:11 > 0:01:14Yes, but you've never driven her yourself.
0:01:14 > 0:01:17But I know how it starts - you just press this.
0:01:17 > 0:01:22- No, not yet!- You have to close the windscreen first.
0:01:24 > 0:01:26OK, now you can start the engine.
0:01:27 > 0:01:29Well done.
0:01:29 > 0:01:32Now, be careful. Steady as she goes.
0:01:32 > 0:01:35Don't worry, Captain, I know what I'm doing.
0:01:40 > 0:01:41Oh!
0:01:41 > 0:01:43THEY GASP
0:01:46 > 0:01:48Oh! Whoops!
0:01:48 > 0:01:51Ah. Remember, take it easy.
0:01:51 > 0:01:52Very easy!
0:01:56 > 0:01:57Oh, whoops!
0:01:59 > 0:02:01Wahey!
0:02:03 > 0:02:05We better keep an eye on the GUP-D,
0:02:05 > 0:02:09- just in case Shellington gets into trouble.- Agreed, Cap.
0:02:09 > 0:02:11I'll check the GUP Finder.
0:02:13 > 0:02:15So far, so good!
0:02:18 > 0:02:21Ah, now, let's see. Remipedes.
0:02:21 > 0:02:23Well, they swim on their backs,
0:02:23 > 0:02:27lots of legs, long antennae and live in dark sea caves.
0:02:27 > 0:02:32Dark sea caves. Oh, now, where can I find a dark sea ca...?
0:02:32 > 0:02:34Oh! Oh, oh!
0:02:35 > 0:02:36Ohhh!
0:02:38 > 0:02:40SHE GASPS
0:02:40 > 0:02:42Oh! Oops!
0:02:42 > 0:02:45Ohhh! Whoops!
0:02:46 > 0:02:47Oh!
0:02:50 > 0:02:55Oh! Jumping jellyfish! A dark sea cave!
0:02:59 > 0:03:00I must investigate.
0:03:01 > 0:03:03CRASH!
0:03:04 > 0:03:07TWEAK GASPS Cap, Shellington has crashed!
0:03:07 > 0:03:10Tweak, sound the Octo-alert.
0:03:11 > 0:03:13Octonauts to the launch bay!
0:03:23 > 0:03:26Octonauts, Shellington has crashed the GUP-D.
0:03:26 > 0:03:29If anything has happened to him, I'm ready.
0:03:29 > 0:03:32The GUP-C is ready too, Cap.
0:03:32 > 0:03:34Peso, Kwazii, let's go.
0:03:35 > 0:03:37Tweak, open the Octo-hatch.
0:03:37 > 0:03:39You got it, Cap.
0:03:39 > 0:03:40Good luck.
0:03:46 > 0:03:52Amazing, look at those stalactites. And these stalagmites.
0:03:55 > 0:04:01Huh? Oh! You're not a remipede! You're a worm.
0:04:02 > 0:04:04SHELLINGTON LAUGHS
0:04:07 > 0:04:09I must investigate further.
0:04:11 > 0:04:13Avast! There's the GUP-D.
0:04:13 > 0:04:17What's left of it. But where's Shellington?
0:04:18 > 0:04:20A sea cave!
0:04:20 > 0:04:22Do you think he could be in there?
0:04:22 > 0:04:24Let's find out.
0:04:24 > 0:04:25GULP!
0:04:26 > 0:04:31Hmm. Mmm. Mm.
0:04:31 > 0:04:33This cave just goes on and on.
0:04:33 > 0:04:34What was that?
0:04:38 > 0:04:41Huh? I must be seeing things.
0:04:44 > 0:04:46Hmm.
0:04:46 > 0:04:49Now, which way to go?
0:04:49 > 0:04:51HE GASPS
0:04:51 > 0:04:54Sounds like there's something down there.
0:05:01 > 0:05:04Shellington's magnifying glass.
0:05:04 > 0:05:10- Oh, no. We've got to find him!- Caves are dangerous places, like mazes.
0:05:10 > 0:05:13Easy to get into, very difficult to find a way out.
0:05:13 > 0:05:18We'll need to go in with a guide rope, so we can find our way back.
0:05:18 > 0:05:21Aye, Captain. Let's use this.
0:05:21 > 0:05:25Good thinking. Octonauts, let's do this.
0:05:25 > 0:05:27- Ready.- Yow!
0:05:34 > 0:05:37What was that? Hello?
0:05:37 > 0:05:40Is someone there? Don't be frightened.
0:05:40 > 0:05:43My name's Shellington. I'm an Octonaut.
0:05:43 > 0:05:45Hello? Hello?
0:05:54 > 0:05:56- Ah!- What are you doing here?
0:05:56 > 0:06:01- This isn't your cave. - I'm a scientist, I was exploring.
0:06:01 > 0:06:07- Oh! You're a remipede. - You bet I am, and so are they.
0:06:08 > 0:06:11- SHELLINGTON GASPS - Oh, my!
0:06:11 > 0:06:17Gentlemen, let's give him the smell test. Assume circle formation.
0:06:20 > 0:06:23One, two, three and smell.
0:06:23 > 0:06:24THEY ALL SNIFF
0:06:28 > 0:06:32THEY CONFER
0:06:32 > 0:06:35Ah, you're not from around here, are you?
0:06:39 > 0:06:42Oh, no, which way now?
0:06:42 > 0:06:47Captain, I say we settle this the pirate way...
0:06:47 > 0:06:49Eeny, meeny, miny, moe, catch a pirate by the toe
0:06:49 > 0:06:53If he hollers, let him go Eeny, meeny, miny, moe.
0:06:53 > 0:06:55That's the one, then.
0:07:04 > 0:07:08This place IS like a maze. I'm glad we have this guide rope,
0:07:08 > 0:07:10so we can find our way back out.
0:07:10 > 0:07:13Yes, especially since we've gone so deep inside.
0:07:13 > 0:07:15Aye, but where's Shellington?
0:07:15 > 0:07:18You'd think we'd have found him by now, mateys.
0:07:19 > 0:07:22- CRASHING - That doesn't sound good.
0:07:23 > 0:07:24The rope!
0:07:24 > 0:07:26Yow!
0:07:26 > 0:07:27Oh.
0:07:34 > 0:07:37Were you following me the whole time?
0:07:37 > 0:07:41You bet I was. We don't get a lot of visitors in our cave,
0:07:41 > 0:07:45so we'd like to know what you're doing here.
0:07:45 > 0:07:48Well, as I said, I'm just exploring.
0:07:48 > 0:07:50Now that you've come this far,
0:07:50 > 0:07:53how are you planning on finding your way out?
0:07:53 > 0:07:57Well... Oh. I hadn't thought about that.
0:07:57 > 0:08:00I might need a little help from you, actually.
0:08:00 > 0:08:04- What makes you think I could help? - Well, you're a remipede.
0:08:04 > 0:08:08You live your whole life finding your way around dark sea caves.
0:08:08 > 0:08:10Mmm, you got that right.
0:08:10 > 0:08:12And you have an excellent sense of smell.
0:08:12 > 0:08:17Right again. You DO know a thing or two about remipedes.
0:08:17 > 0:08:18Hold on.
0:08:18 > 0:08:21HE SNIFFS
0:08:21 > 0:08:26I smell something else. I smell more visitors.
0:08:26 > 0:08:27Three of them.
0:08:27 > 0:08:28HE GASPS
0:08:33 > 0:08:38We'll have to find Shellington soon, or these torches will run out.
0:08:38 > 0:08:40But how are we going to get out?
0:08:40 > 0:08:44We'll have to retrace our steps. This way.
0:08:52 > 0:08:54What's that?
0:08:54 > 0:08:56Octonauts!
0:08:56 > 0:08:57Shellington!
0:08:57 > 0:08:59Are you OK?
0:08:59 > 0:09:03I'm fine. I discovered a very large group of remipedes.
0:09:03 > 0:09:05Um, hello there.
0:09:05 > 0:09:10Hello. So, I bet you're lost too, just like your friend here.
0:09:10 > 0:09:14I'm afraid so. We keep taking the wrong turn.
0:09:16 > 0:09:18Now we'll never find our way out.
0:09:18 > 0:09:20Why not?
0:09:20 > 0:09:22Because it's so dark.
0:09:22 > 0:09:26That makes no difference to me. I am blind.
0:09:26 > 0:09:27Blind?!
0:09:27 > 0:09:30But how do you find your way around?
0:09:30 > 0:09:33The same as any remipede. We use our other senses.
0:09:33 > 0:09:37Smelling, touching, listening.
0:09:37 > 0:09:40Of course! And if the remipedes lead the way...
0:09:40 > 0:09:44..We can listen and follow their voices!
0:09:44 > 0:09:48- And we'll find our way out! - Ha-ha, you sure will!
0:09:48 > 0:09:51Octonauts, follow those remipedes.
0:09:55 > 0:09:57Come on, this way.
0:09:59 > 0:10:01Follow, follow, follow.
0:10:01 > 0:10:03Nearly there!
0:10:08 > 0:10:10Oh, thank you, remipedes.
0:10:10 > 0:10:16No problem. I'd be happy to show you around this cave again, any time.
0:10:17 > 0:10:20OK, let's head for home.
0:10:20 > 0:10:23OK, Captain. I'll follow you in the GU...
0:10:23 > 0:10:26Oh. What happened to the GUP-D?
0:10:26 > 0:10:31I, er, think you may have bumped into a few things on the way here,
0:10:31 > 0:10:34I think it's better if I drive home.
0:10:35 > 0:10:39- I could do better this time.- It's just there's some tricky turns.
0:10:39 > 0:10:43- I wonder if Kwazii would let me drive the GUP-B.- Doubt it.
0:10:43 > 0:10:45Oh! I'm much better now!
