0:00:54 > 0:00:58I can't wait to see how my biggest patient is doing.
0:00:58 > 0:01:03I can't wait to see if your patient is really as big as you say, Peso.
0:01:03 > 0:01:06Here we are, the coral reef.
0:01:06 > 0:01:07Where's your patient?
0:01:07 > 0:01:10Captain, I don't see anything big.
0:01:10 > 0:01:12It's right here, Kwazii.
0:01:12 > 0:01:15Mt patient is the coral reef.
0:01:15 > 0:01:18- What?- Of course!
0:01:18 > 0:01:23Coral reefs are made of coral, which is alive.
0:01:23 > 0:01:26The coral reef needs a check-up like any other creature.
0:01:26 > 0:01:31That's true. The coral reef is home to lots of different animals.
0:01:33 > 0:01:36If anything happened to the coral, they'd have nowhere to live.
0:01:36 > 0:01:40Aye, that is a big patient!
0:01:43 > 0:01:47Hmm, that's not good.
0:01:47 > 0:01:48What's wrong, Peso?
0:01:48 > 0:01:51This coral is turning white, Shellington,
0:01:51 > 0:01:53which means it's getting sick.
0:01:53 > 0:01:55There's another white spot over here.
0:01:55 > 0:01:59Peso, you'd better take a look at this.
0:01:59 > 0:02:05Oh, no! The entire coral reef is getting sick.
0:02:05 > 0:02:07If anything happens to it,
0:02:07 > 0:02:10all these creatures will have to find a new home.
0:02:10 > 0:02:12There's only one thing to do.
0:02:12 > 0:02:14Kwazii, Shellington, I need you to find me
0:02:14 > 0:02:18- a small piece of healthy coral on the seafloor.- Aye, Peso.
0:02:18 > 0:02:22- I'll need to borrow your hydro drill.- What are you planning?
0:02:22 > 0:02:25An emergency coral transplant!
0:02:26 > 0:02:30I drill a tiny hole into the sick coral...
0:02:30 > 0:02:33- Here you go. A piece of coral. - Perfect.
0:02:33 > 0:02:38Now, I'll put this piece of healthy coral into the hole and...
0:02:39 > 0:02:42There! That's a coral transplant!
0:02:42 > 0:02:48- The piece of healthy coral will help make the sick coral better.- Look!
0:02:48 > 0:02:52Great! We've saved the coral reef and just in time for lunch.
0:02:52 > 0:02:56I don't think so. Look at all those white spots.
0:02:56 > 0:03:00I'm going to have to do a lot more coral transplants
0:03:00 > 0:03:04- to make this reef healthy again. - We're going to help you!
0:03:04 > 0:03:06Let's sound the Octo alert.
0:03:07 > 0:03:10- SIREN WAILS - Octonauts to the HQ.
0:03:10 > 0:03:13MUSIC
0:03:20 > 0:03:23Octonauts, the coral reef is sick.
0:03:23 > 0:03:25Our mission is to help Peso
0:03:25 > 0:03:29do as many coral transplants as it takes to make it healthy.
0:03:29 > 0:03:32But the coral reef is huge! What's the plan?
0:03:33 > 0:03:35Dashi - you, Kwazii and Tunip
0:03:35 > 0:03:39will search for healthy pieces of coral on the seafloor.
0:03:39 > 0:03:43Shellington and Professor Inkling will sort through them.
0:03:43 > 0:03:46Tweak and I will drill tiny holes in the reef
0:03:46 > 0:03:50and Peso will put the coral pieces into the holes.
0:03:50 > 0:03:53- Now, everybody got it? - ALL: Got it!
0:03:53 > 0:03:55Octonauts, let's do this.
0:03:58 > 0:04:03If we all work together, the reef will be healthy again in no time.
0:04:05 > 0:04:07DOLPHINS GIGGLE
0:04:07 > 0:04:10A-ha! Another piece of coral.
0:04:11 > 0:04:15Yah! Oh, just a sea sponge.
0:04:16 > 0:04:19Oh, ouch! Spiky sea urchin!
0:04:19 > 0:04:22- IT GRUMBLES - Sorry, little urchin.
0:04:22 > 0:04:27These coral pieces are harder to find than I... What was that?!
0:04:30 > 0:04:33DOLPHINS GIGGLE
0:04:36 > 0:04:38SPLASH!
0:04:38 > 0:04:42Hmm, someone's playing a trick on me.
0:04:42 > 0:04:46DOLPHINS GIGGLE
0:04:46 > 0:04:48Uh, shiver me whiskers!
0:04:49 > 0:04:53You should've seen the look on your face!
0:04:54 > 0:04:58Dolphins, what's the big idea? Playing tricks on me while...
0:04:58 > 0:05:02We were just playing around. What are you doing here anyway?
0:05:02 > 0:05:04We're blowing bubble rings!
0:05:06 > 0:05:09No, I'm too busy to play right now.
0:05:09 > 0:05:11Oh, suit yourself.
0:05:11 > 0:05:13Yeah, yeah, very funny.
0:05:13 > 0:05:16There's a pirate here trying to work!
0:05:19 > 0:05:21Thank you, Dashi.
0:05:26 > 0:05:29Have a look at this one, Shellington?
0:05:29 > 0:05:33This one looks very healthy! I'll put it with the other red ones.
0:05:33 > 0:05:35Jumping jellyfish!
0:05:35 > 0:05:37Oh! Hey-ho!
0:05:37 > 0:05:39- Tag, you're it. - DOLPHINS GIGGLE
0:05:39 > 0:05:42Oh, my.
0:05:44 > 0:05:47- There you go, Peso. - Thanks, Tweak.
0:05:48 > 0:05:51Steady. Steady.
0:05:51 > 0:05:53- What you doing?- Flappety flippers!
0:05:57 > 0:06:01Cool. Do you want to play catch? That's one of our favourite games.
0:06:01 > 0:06:02Here. Catch.
0:06:02 > 0:06:07Whoa! Careful with that. Sorry, dolphins, but we've got work to do.
0:06:07 > 0:06:10- Maybe some other time.- There's got to be someone who wants to play!
0:06:10 > 0:06:17- Come on!- We've been working for hours and we have so much to do.
0:06:17 > 0:06:21At the speed we're going, it could take days to finish.
0:06:21 > 0:06:24These dolphins aren't making things any easier.

0:06:45 > 0:06:50Barnacles to Shellington. These dolphins won't leave us alone.
0:06:50 > 0:06:52Why are they acting like this?
0:06:52 > 0:06:56It's normal dolphin behaviour. Dolphins are curious creatures.
0:06:56 > 0:06:59- They...- Ooh! What's this?
0:07:01 > 0:07:03They love to play with each other.
0:07:05 > 0:07:07And make up new games.

0:07:34 > 0:07:38Oh, this is starting to get out of hand.
0:07:38 > 0:07:39Attention, dolphins!
0:07:39 > 0:07:42We have very important work to do!
0:07:42 > 0:07:44If you could please just... Whey!

0:08:28 > 0:08:30Sorry, but play time is over.
0:08:30 > 0:08:34We Octonauts are trying to save the coral reef. I need to get back.
0:08:34 > 0:08:38- What's wrong with the reef? - It's very sick.
0:08:38 > 0:08:42We find pieces of healthy coral and put them in tiny holes in the reef.
0:08:42 > 0:08:46Oh, so that's what you guys were doing?!
0:08:46 > 0:08:49Find the coral and put it in the hole.
0:08:49 > 0:08:51Hey, that kind of sounds like a game.
0:08:51 > 0:08:54Can I play... help, too?
0:08:54 > 0:08:58Hmm, well, we do need all the help we can get.

0:09:05 > 0:09:07- I've found a piece!- Ah!
0:09:07 > 0:09:10That sea sponge on your nose is a pretty good tool
0:09:10 > 0:09:13- for finding coral. - Found another one!
0:09:13 > 0:09:18- Could you show the other dolphins how to do that?- Of course!
0:09:18 > 0:09:22- Grab on. I'll give you a ride back to the reef.- Let's go!
0:09:23 > 0:09:25- Ready, everybody?!- ALL: Ready!
