0:00:02 > 0:00:03SIREN WAILS
0:00:03 > 0:00:05Octonauts - to your stations.
0:00:07 > 0:00:11Barnacles! Kwazii! Peso!
0:00:38 > 0:00:41- Explore!- Rescue!- Protect!
0:00:41 > 0:00:44Octonauts!
0:00:49 > 0:00:53Octonauts, tonight we have a very special dinner guest. Dashi?
0:00:53 > 0:00:57Everyone, I'd like you to meet my little sister Kashi.
0:00:57 > 0:00:59Uh, Kashi?
0:00:59 > 0:01:03Oh. Sorry, I'm on the very last page of a Donna Doxy mystery -
0:01:03 > 0:01:06The Case Of The Curios Cuckoo Clock.
0:01:06 > 0:01:09Once you start a Donna Doxy book, it's really hard to stop.
0:01:09 > 0:01:13- Who's Donna Doxy? - The detective undaunted by danger!
0:01:13 > 0:01:17She's the main character in a series of mystery books.
0:01:17 > 0:01:19They were my favourite growing up.
0:01:19 > 0:01:22Dashi gave her whole collection to me. All 100 books!
0:01:22 > 0:01:25I've read 54 of them - 55 when I finish this one.
0:01:25 > 0:01:27I love a good mystery too, me hearty.
0:01:27 > 0:01:31Donna Doxy's taught me all kinds of tricks for solving mysteries.
0:01:31 > 0:01:35- Like what, matey?- Well, I can tell a lot about a person
0:01:35 > 0:01:38by looking closely. Take you, for instance.
0:01:38 > 0:01:42We've only just met, but your eye patch and that tiny piece
0:01:42 > 0:01:43of your ear that's missing
0:01:43 > 0:01:47tell me you've been in some dangerous situations.
0:01:47 > 0:01:50- I'd say you're reckless but brave.- Mmm.
0:01:50 > 0:01:53And from the way your tail keeps twitching,
0:01:53 > 0:01:56- I'd also say you're not very patient.- Oh.
0:01:56 > 0:01:59Ha-ha. Amazing! You've described Kwazii perfectly.
0:01:59 > 0:02:03And one more thing - there's a trace of pudding on your paw.
0:02:03 > 0:02:07You must have snuck in a little dessert before your dinner.
0:02:07 > 0:02:08HE LAUGHS NERVOUSLY
0:02:08 > 0:02:12- Wow.- Good job, Kashi. - That was incredible.- She's good.
0:02:12 > 0:02:13Possibly too good.
0:02:13 > 0:02:18It's pretty hard to get anything past my little sister, right, Kashi?
0:02:18 > 0:02:21Um... Except when she's reading.
0:02:21 > 0:02:25Right, are you ready for the best sister-sleepover-readathon ever?
0:02:25 > 0:02:30- I'm ready. Which one do you want to read first, Dashi?- Oh, um...
0:02:30 > 0:02:35The Case Of The Disappearing Camera. It's one of my favourites.
0:02:42 > 0:02:44THEY SNORE
0:02:44 > 0:02:46SIREN WAILS
0:02:46 > 0:02:47Octonauts - to the launch bay.
0:02:47 > 0:02:52- Oh, wow! An actual Octo-alert. - Come on!
0:03:01 > 0:03:05Octonauts, this sea snail needs our help. Her babies are missing.
0:03:05 > 0:03:07It was horrible!
0:03:07 > 0:03:11Something monstrous tore through our lovely kelp forest home
0:03:11 > 0:03:14- and now my babies are gone! - SHE CRIES
0:03:14 > 0:03:16We need to find those baby sea snails, and fast.
0:03:16 > 0:03:19Octonauts - to the kelp forest!
0:03:19 > 0:03:21Captain Barnacles, can I help too?
0:03:21 > 0:03:24- Erm...- Kashi is very good at working out clues.
0:03:24 > 0:03:27I noticed you're always wearing that uniform,
0:03:27 > 0:03:31which means you're always ready for the next mission. Me too, sir.
0:03:31 > 0:03:35All right, then, Kashi. Everyone, let's do this!
0:03:44 > 0:03:46Dashi, what is that?
0:03:46 > 0:03:50Just orcas. We see them around a lot here this time of year.
0:03:50 > 0:03:53Come on, now, we have to keep up.
0:03:55 > 0:03:59There! That's right where my babies were.
0:03:59 > 0:04:03Peso, see if you can find any creatures who saw what happened.
0:04:03 > 0:04:07Shellington, Dashi and Kashi, you look for clues right here.
0:04:07 > 0:04:11Kwazii, we'll search the nearby kelp for baby snails.
0:04:12 > 0:04:15This kelp is torn and crushed.
0:04:15 > 0:04:20The whole are almost looks like a giant footprint. Let's measure it.
0:04:24 > 0:04:28- It's as big as a bus!- Somebody must have seen what caused this mess.
0:04:28 > 0:04:30It's too huge to miss.
0:04:30 > 0:04:34So, you say you saw a strange creature in the kelp?
0:04:34 > 0:04:37Sure as my shell, I did. Big fellow, bumpy all over.
0:04:37 > 0:04:40No way - that thing was smooth, not bumpy.
0:04:40 > 0:04:44Erm, thank you...I think.
0:04:44 > 0:04:48I didn't see the thing, but I heard it make a creaky noise.
0:04:48 > 0:04:50No, it was a bellowing sound.
0:04:50 > 0:04:54- Creaky!- Bellowy!- I heard it going, "Snort, snort, snort!"
0:04:54 > 0:04:58Flappity flippers! Everyone describes the creature differently.
0:04:58 > 0:05:01This is going to be a hard mystery to solve.
0:05:03 > 0:05:06- Captain, did you find my babies? - Not yet, but don't worry,
0:05:06 > 0:05:10we'll find them. Did anyone see who took the baby sea snails?
0:05:10 > 0:05:14We've looking for a creature who's bumpy but also smooth, and it makes
0:05:14 > 0:05:18- a creaking, bellowing or snorting sound.- Those are different.
0:05:18 > 0:05:22- That doesn't help much.- Well, we know for sure the creature is big.
0:05:22 > 0:05:24It left a huge print in the kelp.
0:05:24 > 0:05:28Much of the forest nearby was crushed down or torn away.
0:05:28 > 0:05:30The baby snails could have been carried away
0:05:30 > 0:05:33- on a piece of torn kelp.- My babies!
0:05:33 > 0:05:37- But where did the creature take them?- Creature?
0:05:37 > 0:05:41I'd say we're looking for a monster - a kelp monster!
0:05:41 > 0:05:46- Ohh!- Whatever it is, we've got to find it. But be careful, everyone.
0:05:46 > 0:05:50There's something big and possibly dangerous out there.
0:05:50 > 0:05:54No sign of any creature or snails.
0:05:54 > 0:05:58Sure is quiet...and shadowy...
0:05:58 > 0:06:00with lots of places to hide.
0:06:00 > 0:06:03Ohh! The kelp monster!
0:06:03 > 0:06:05He's just a ray. They normally live here.
0:06:05 > 0:06:09And he's not big enough to be the creature.
0:06:09 > 0:06:11Right. I knew that.
0:06:11 > 0:06:16Look! Torn kelp. And there's more over here.
0:06:16 > 0:06:20And here!
0:06:20 > 0:06:22Hmmm. Now, this could lead us to...
0:06:22 > 0:06:25- Ahh!- Ah!- Whoa!
0:06:25 > 0:06:29- Why are you sneaking up on me? - Why are you hiding in the kelp?
0:06:29 > 0:06:30I'm not hiding, I'm floating,
0:06:30 > 0:06:34and it was very relaxing until you swam right into me.
0:06:34 > 0:06:35How big is he?
0:06:35 > 0:06:39- He's not as big as a bus.- What do you mean bus? I'm a harbour seal.
0:06:39 > 0:06:43- Sorry to have bothered you, Mr Harbour Seal.- That's all right.
0:06:43 > 0:06:46You two are strange, but not the strangest thing
0:06:46 > 0:06:48I've bumped into tonight.
0:06:48 > 0:06:50What else have you bumped into?
0:06:50 > 0:06:53Well, like I said, it was strange.
0:06:53 > 0:06:57It was big. It nearly knocked me over when it scraped itself
0:06:57 > 0:07:00- along the sea floor. Left behind a big hole.- A hole?
0:07:00 > 0:07:04Yeah, you can see it for yourself on the other side of this kelp.
0:07:04 > 0:07:06- Thanks!- Let's go.
0:07:07 > 0:07:11Now that is unusual...and it might be a clue.
0:07:11 > 0:07:14Dashi, look - shells.
0:07:14 > 0:07:17But not snail shells - barnacle shells.
0:07:17 > 0:07:20These belong to creatures called barnacles
0:07:20 > 0:07:24that are usually attached to rocks or even other creatures.
0:07:24 > 0:07:27And look - they lead in there.
0:07:27 > 0:07:29It's definitely a clue.
0:07:29 > 0:07:32As Donna Doxy says, "We're hot on the trail!"
0:07:35 > 0:07:38The trail just...ends.
0:07:38 > 0:07:42Oh! I was so sure we were onto something.
0:07:42 > 0:07:44- CREATURE SNORTS - Snort!
0:07:44 > 0:07:47CREATURE BELLOWS Bellow.
0:07:47 > 0:07:50- CREATURE CREAKS BOTH:- Creak!
0:07:52 > 0:07:54THEY GASP
0:07:54 > 0:07:58Huh? Nothing to see here. Just a big clump of kelp.
0:07:58 > 0:08:00Is that a whale?
0:08:00 > 0:08:02Yes, a grey whale.
0:08:02 > 0:08:06You can tell because he has bumps on his back instead of a dorsal fin.
0:08:06 > 0:08:11So, he's bumpy, but also smooth! Just like the crab and urchin said.
0:08:11 > 0:08:16And he's making all the noises they mentioned, too.
0:08:16 > 0:08:18Mystery solved!
0:08:18 > 0:08:22The kelp monster that took the baby snails was you - a grey whale!
0:08:22 > 0:08:27Huh? Don't know what you're talking about. I'm just kelp!
0:08:27 > 0:08:29Kelp doesn't talk.
0:08:29 > 0:08:34Oh, OK, maybe not, but please don't give away my disguise.
0:08:34 > 0:08:38I'm hiding from a pod of orca whales. They want to eat me.
0:08:40 > 0:08:42Where'd that grey whale go?
0:08:42 > 0:08:44Let's look over here.
0:08:44 > 0:08:46HE GROANS
0:08:46 > 0:08:48We won't give you away, promise.
0:08:48 > 0:08:51But we'd like to check you for baby snails.
0:08:51 > 0:08:54They may have gotten caught up in your kelp disguise.
0:08:54 > 0:08:56Oh. Er, go ahead, then.
0:09:00 > 0:09:02There they are!
0:09:02 > 0:09:04THEY CHATTER
0:09:04 > 0:09:09Oh, sorry about that. I didn't know I had any creatures on my head.
0:09:09 > 0:09:12Oh, let's get you back to your mum.
0:09:12 > 0:09:15Oh, my precious little babies. I was so worried!
0:09:15 > 0:09:17- BABIES:- Mummy! Mummy!
0:09:17 > 0:09:21- How did you find them? - By following the clues.
0:09:21 > 0:09:24First we discovered a scraped-up part of the sea floor,
0:09:24 > 0:09:28then we tracked a trail of barnacle shells to the end,
0:09:28 > 0:09:30where we heard a spooky noise.
0:09:30 > 0:09:34That's when we found the grey whale accidentally carrying the snails.
0:09:34 > 0:09:36Now it all makes sense.
0:09:36 > 0:09:39Grey whale snouts are covered with barnacles.
0:09:39 > 0:09:42He must have left the trail by scraping his mouth
0:09:42 > 0:09:44along the sea floor to eat.
0:09:44 > 0:09:46- But where is the whale?- Hiding.
0:09:46 > 0:09:51Really? Grey whales usually travel to warmer water this time of year.
0:09:51 > 0:09:54There's a pod of orcas after him - and they'd like to eat him.
0:09:54 > 0:09:56Oh.
0:09:56 > 0:10:00Only me! This kelp forest is a safe place for me to hide!
0:10:00 > 0:10:02I think we can help you.
0:10:03 > 0:10:07Our whale-tracker shows that the orcas are gone!
0:10:07 > 0:10:09Oh, what a relief.
0:10:09 > 0:10:12Before I go, can I ask one last favour?
0:10:12 > 0:10:16There's a piece of kelp stuck in my blow hole. Would you mind?
0:10:16 > 0:10:20This will make the perfect souvenir for our case.
0:10:20 > 0:10:23Ohh! Thank you for all your help.
0:10:23 > 0:10:26- Bye-bye!- Bye-bye!
0:10:26 > 0:10:30Now, how about finishing up our Donna Doxy readathon?
0:10:30 > 0:10:35I've got a better idea. Instead of reading a mystery, let's write one!
0:10:35 > 0:10:39It's about two sisters who team up to solve cases.
0:10:39 > 0:10:42The little sister is the brains of the two.
0:10:42 > 0:10:44THEY LAUGH
