0:02:26 > 0:02:29Octonauts, we've lost contact with Dashi.
0:02:29 > 0:02:31We're going after her.
0:02:31 > 0:02:33Tweak, we need the GUP-A right away.
0:02:33 > 0:02:36She's shipshape and ready to go.
0:02:36 > 0:02:38Peso, Kwazii, into the GUP-A.
0:02:38 > 0:02:40Yow!
0:02:43 > 0:02:45Tweak, open the Octohatch.
0:02:45 > 0:02:47Aye-aye, Cap.
0:02:55 > 0:02:57Any sign of Dashi yet?
0:02:57 > 0:02:59Not yet, Captain.
0:02:59 > 0:03:01There she is,
0:03:01 > 0:03:03by that rock over there.
0:03:10 > 0:03:12Dashi, can you hear me?
0:03:13 > 0:03:15CLAP! CLAP! CLAP!
0:03:15 > 0:03:16Huh? Oh!
0:03:16 > 0:03:20I... I hear you, Captain.
0:03:20 > 0:03:22Ah, she's awake!
0:03:23 > 0:03:25CLAP! CLAP!
0:03:27 > 0:03:29Wait! You need a checkup.
0:03:30 > 0:03:32Oh...
0:03:34 > 0:03:35How do you feel?
0:03:35 > 0:03:38- I feel OK.- You seem fine.
0:03:38 > 0:03:40Oh! My camera!
0:03:40 > 0:03:43Oh, it's fine too.
0:03:43 > 0:03:45Dashi, what exactly happened?
0:03:45 > 0:03:47I was about to take a picture
0:03:47 > 0:03:50and then I heard a very loud BOOM!
0:03:50 > 0:03:52It was so loud that it knocked me out
0:03:52 > 0:03:54and that's all I remember.
0:03:54 > 0:03:57What could make a sound that powerful?
0:03:57 > 0:04:00I know what, me hearty!
0:04:00 > 0:04:03Dashi must have been struck down by the dreaded...
0:04:03 > 0:04:06giant shrimp monster!
0:04:06 > 0:04:07But shrimps are small.
0:04:07 > 0:04:10This one's big! Ah-ha-ha-ha!
0:04:11 > 0:04:15When the shrimp monster snaps its giant claws
0:04:15 > 0:04:20the BOOM is loud enough to knock out anyone who hears it.
0:04:20 > 0:04:22- PESO GULPS - Er, Kwazii,
0:04:22 > 0:04:26I'm not sure this was a giant shrimp monster.
0:04:26 > 0:04:29I'm sure I didn't see any giant claws anywhere.
0:04:29 > 0:04:33Octonauts, let's find out whatever made that boom and stop it
0:04:33 > 0:04:38- before someone else gets knocked out.- Aye-aye, Captain!
0:04:38 > 0:04:41We'll divide up and search the area,
0:04:41 > 0:04:45but first, ear protectors, everyone.
0:04:45 > 0:04:49These will keep us safe from the boom of the giant shrimp monster.
0:04:49 > 0:04:51I feel safer already.
0:04:51 > 0:04:55- Kwazii, you search those rocks. - Aye-aye, Captain!
0:04:55 > 0:04:58Dashi, you be our lookout in GUP-A.
0:04:58 > 0:05:01Peso, you take that area over there.
0:05:01 > 0:05:03Aye-aye, Captain.
0:05:12 > 0:05:13Huh?
0:05:13 > 0:05:16That fish still needs a checkup.
0:05:20 > 0:05:25Wait! I help any creature who is sick or hurt.
0:05:26 > 0:05:30I'll just take these off for a second,
0:05:30 > 0:05:32so I can use my stethoscope.
0:05:36 > 0:05:38BOOM!
0:05:38 > 0:05:41BOING!
0:05:43 > 0:05:47Hello, matey! No sign of the shrimp monster yet?
0:05:47 > 0:05:48Peso?
0:05:48 > 0:05:50Ah, Peso,
0:05:50 > 0:05:54the shrimp monster snaps his giant claws again.
0:05:54 > 0:05:56Come on, I'll take you back to the GUP.
0:06:05 > 0:06:07Kwazii to Captain Barnacles.
0:06:09 > 0:06:12Barnacles here. Go ahead, Kwazii.
0:06:12 > 0:06:15'Peso's been knocked out, Captain.'
0:06:15 > 0:06:17I'm on my way back! Barnacles out.
0:06:18 > 0:06:20Who's there?
0:06:23 > 0:06:24BOOM!
0:06:24 > 0:06:27BOING!
0:06:28 > 0:06:29Peso!
0:06:29 > 0:06:32- Peso! - CLAP! CLAP! CLAP!
0:06:32 > 0:06:34Can you hear me?
0:06:34 > 0:06:36I... I... I'm OK.
0:06:36 > 0:06:40Tell me, did you see the shrimp monster, me hearty?
0:06:40 > 0:06:44No, but there was a big boom noise like you said, Dashi.
0:06:44 > 0:06:46PESO GASPS Oh, no!
0:06:46 > 0:06:51- Don't those belong to the captain? - Yow! We've got to find him!
0:06:51 > 0:06:54- I'm coming with you! - I'll call you if I see the captain.
0:07:05 > 0:07:07KWAZII GASPS
0:07:07 > 0:07:09Peso, you help the captain.
0:07:09 > 0:07:13I'm going to stop this shrimp monster once and for all!
0:07:19 > 0:07:21MUFFLED BOOM
0:07:21 > 0:07:25Arr, I can hear it, but I can't see it.
0:07:25 > 0:07:27MUFFLED BOOM
0:07:35 > 0:07:37- BOOM! - Aaargh!
0:07:37 > 0:07:38Argh!
0:07:38 > 0:07:44Show yourself and your giant claws, you scurvy beast!
0:07:44 > 0:07:46KWAZII GASPS
0:07:50 > 0:07:51Oh, no you don't!
0:07:51 > 0:07:53Peso, bandage wrap. Now!
0:07:55 > 0:07:58I surrender! I surrender!
0:07:58 > 0:08:01You're the giant shrimp monster?!
0:08:01 > 0:08:04I'm not a giant shrimp monster!
0:08:04 > 0:08:06I'm a snapping shrimp.
0:08:06 > 0:08:08BOTH: Snapping shrimp?
0:08:08 > 0:08:13Yes, I'm one of the loudest creatures in the sea.
0:08:13 > 0:08:17We noticed! But why have you been attacking Octonauts?
0:08:17 > 0:08:20I'm the one who's been under attack!
0:08:20 > 0:08:22I thought all of you were after me,
0:08:22 > 0:08:25so I did what a snapping shrimp does -
0:08:25 > 0:08:27I used my loud claw snap
0:08:27 > 0:08:30to protect myself from animals who want to eat me.
0:08:30 > 0:08:33We promise we don't want to eat you.
0:08:33 > 0:08:37Ah, we thought YOU were coming after US!
0:08:37 > 0:08:42- Sorry for the misunderstanding. - No hard feelings,
0:08:42 > 0:08:46but do you think you could untie my claw now?
0:08:46 > 0:08:48Erm, no more snapping?
0:08:48 > 0:08:50Snapping shrimp's honour!
0:08:51 > 0:08:55But how can such a tiny little thing like you
0:08:55 > 0:08:57make one of the biggest sounds in the sea?
0:08:57 > 0:09:00Hmm, I don't know.
0:09:00 > 0:09:04I just kind of snap my claw like this.
0:09:04 > 0:09:05ALL: No!
0:09:05 > 0:09:08All right! I was just trying to work out
0:09:08 > 0:09:11how my claw makes that boom, that's all.
0:09:11 > 0:09:17Hmm, I think Dashi and her camera can help you do that.
0:09:17 > 0:09:19Really?
0:09:21 > 0:09:25Dashi, make sure your ear protectors are fastened correctly
0:09:31 > 0:09:34Let's make a video of your claw snap.
0:09:34 > 0:09:35All right.
0:09:35 > 0:09:38Ready? Go!
0:09:41 > 0:09:43BOOM!
0:09:43 > 0:09:48I got it! Now let's watch the video of it in slow motion.
0:09:58 > 0:10:00Snappy's claw opens
0:10:00 > 0:10:03and look at that bubble starting to form!
0:10:03 > 0:10:05And there goes that bubble,
0:10:05 > 0:10:07right out of the claw.
0:10:07 > 0:10:09It looks like it's going to...
0:10:11 > 0:10:12..pop!
0:10:12 > 0:10:15- Jumping jellyfish!- Indeed!
0:10:15 > 0:10:17Would you look at that!
0:10:17 > 0:10:19- Oooh!- Ah!
0:10:19 > 0:10:23Did you see how your big claw can make a bubble very fast?
0:10:23 > 0:10:25When the bubble pops...
0:10:25 > 0:10:27boom!
0:10:27 > 0:10:29That's how a little snapping shrimp
0:10:29 > 0:10:32makes one of the biggest sounds in the sea!
0:10:32 > 0:10:37Thanks for showing me, Octonauts. Can we see it again?
0:10:37 > 0:10:39THEY ALL LAUGH
