0:00:54 > 0:00:56- Uh-oh!
0:01:01 > 0:01:03- Is there a doctor in the house?
0:01:06 > 0:01:08- Oh, no, what happened to you?
0:01:08 > 0:01:11- The reef, - I got knocked off the reef.
0:01:11 > 0:01:16- My name's Pegwn and I help - any creature who's hurt or sick.
0:01:16 > 0:01:17- May I examine you?
0:01:18 > 0:01:21- So polite, I like this one. - Examine away.
0:01:23 > 0:01:25- VOICES
0:01:27 > 0:01:29- That does sound strange!
0:01:29 > 0:01:33- We'll need to take an X-ray - to see what's going on in there.
0:01:34 > 0:01:39- Flapitty flippers! - There's a tiny shrimp inside you.
0:01:39 > 0:01:41- And there's a sea star and a snail.
0:01:41 > 0:01:44- There are all kinds - of creatures inside you.
0:01:45 > 0:01:47- Of course - I'm a sea sponge.
0:01:47 > 0:01:51- But I feel like there's something - inside me that doesn't belong.
0:01:52 > 0:01:55- We need you in the sick bay - right away!
0:01:56 > 0:02:03- This is wonderful! I've never seen - a finer example of commensalism!
0:02:03 > 0:02:05- Co-what-alism?
0:02:05 > 0:02:06- Co-what-alism?- - Commensalism.
0:02:06 > 0:02:11- All the creatures inside the sponge - get a safe place to live...
0:02:11 > 0:02:14- ..but the sponge - doesn't get anything from them.
0:02:14 > 0:02:18- It's why they call us sponges - the hotels of the sea!
0:02:18 > 0:02:20- It doesn't bother you?
0:02:20 > 0:02:25- Not at all, I've never had - any problems... until today.
0:02:25 > 0:02:29- Yes, and if the sponge isn't happy, - we aren't happy!
0:02:34 > 0:02:36- Where are we anyway?
0:02:36 > 0:02:41- Nobody asked us before - they stuck us in this pan.
0:02:42 > 0:02:45- What's with all the poking - and light shining in my eyes?
0:02:46 > 0:02:49- This used to be a nice place - to live!
0:02:50 > 0:02:53- Come on, everybody, - let's get out of here.
0:02:57 > 0:02:59- Uh-oh! They're running out of room.
0:02:59 > 0:03:03- We need to find places - to put all these creatures... fast!
0:03:06 > 0:03:09- Oh, oh, oh.
0:03:09 > 0:03:11- Sorry... erm, excuse me.
0:03:16 > 0:03:18- Finally, a room with a view!
0:03:18 > 0:03:20- That's the last one, Pegwn.
0:03:20 > 0:03:24- Do you feel better - now that everybody's out?
0:03:24 > 0:03:27- No, there's still - something in there.
0:03:28 > 0:03:29- What could it be?
0:03:30 > 0:03:33- I don't know, but there's - only one way to find out.
0:03:33 > 0:03:35- We've got to take - a closer look inside.
0:03:36 > 0:03:38- Spongerscope, please.
0:03:43 > 0:03:46- This shouldn't hurt - but you may feel a little...
0:03:46 > 0:03:48- Oh, oh!
0:03:48 > 0:03:49- ..tickle.
0:03:51 > 0:03:53- Having a look in... no.
0:03:58 > 0:03:59- See anything yet, Pegwn?
0:03:59 > 0:04:01- See anything yet, Pegwn?- - A-ha!
0:04:03 > 0:04:06- What is that creature?
0:04:06 > 0:04:10- It looks like a louse, - a whale louse.
0:04:10 > 0:04:12- What are you looking at?
0:04:13 > 0:04:16- A louse, - no wonder I'm feeling so lousy!
0:04:16 > 0:04:18- It doesn't belong - inside of me.
0:04:20 > 0:04:22- You're telling me!
0:04:22 > 0:04:25- He doesn't look well at all.
0:04:25 > 0:04:29- Of course he doesn't! Whale lice - can only survive on whales.
0:04:30 > 0:04:32- Not inside sponges.
0:04:32 > 0:04:38- Excuse me, Mr Louse, we need to get - you out of this sponge right away!
0:04:38 > 0:04:41- Oh, no! No way! I'm a whale louse.
0:04:41 > 0:04:45- I'm not leaving until somebody - finds me a whale to live on.
0:04:46 > 0:04:50- The sponge won't feel better - until the louse is out of her.
0:04:50 > 0:04:55- The louse won't feel better - until he's back on a whale.
0:04:55 > 0:04:59- Then there's only one thing to do. - Sound the Octo-alert!
0:05:01 > 0:05:03- Octonots, to the HQ!
0:05:12 > 0:05:16- Octonots, we have to find a whale - for a sick whale louse!
0:05:17 > 0:05:19- And we need to find it fast!
0:05:19 > 0:05:23- Both the sponge and the louse - are feeling worse and worse.
0:05:24 > 0:05:28- There'll be plenty of whales - swimming these waters.
0:05:28 > 0:05:33- We'll find the nearest one and - give the little castaway a new home.
0:05:33 > 0:05:34- It's not that simple.
0:05:35 > 0:05:39- Different kinds of whale lice - live on different kinds of whale.
0:05:39 > 0:05:43- We have to work out which whale - species this louse came from.
0:05:44 > 0:05:46- I'm running a scan now.
0:05:48 > 0:05:52- There, looks like this louse - came from a sperm whale.
0:05:53 > 0:05:56- There's no time to lose. - Let's do this!
0:06:01 > 0:06:05- Don't worry, we'll have this louse - out of you in no time.
0:06:05 > 0:06:07- As soon as we find a sperm whale.
0:06:10 > 0:06:12- There's something big coming up.
0:06:14 > 0:06:15- It's a whale!
0:06:17 > 0:06:21- Oh, but it's a blue whale, - not a sperm whale.
0:06:21 > 0:06:23- Hmmm, keep looking, everyone.
0:06:25 > 0:06:26- There!
0:06:26 > 0:06:29- There!- - No, that's a humpback whale.
0:06:29 > 0:06:30- I knew that.
0:06:31 > 0:06:34- I'm starting to feel a little faint.
0:06:34 > 0:06:38- Oh, you're feeling faint - - how do you think I feel?
0:06:39 > 0:06:41- Hurry, they're getting worse.
0:06:41 > 0:06:43- There's a whale nearby.
0:06:46 > 0:06:48- I can't tell what kind it is.
0:06:48 > 0:06:51- It's a... it's a...
0:06:51 > 0:06:54- ..sperm whale!
0:06:54 > 0:06:58- Excellent! Pegwn, - you'd better suit up... uh-oh!
0:06:58 > 0:07:01- Hey, you stay away from my baby!
0:07:01 > 0:07:06- The whale's mother. Sperm whales - do anything to protect their young.
0:07:06 > 0:07:10- Hang on, everyone! Wow... argh!
0:07:13 > 0:07:14- She's not giving up!
0:07:17 > 0:07:21- I'll keep her distracted. - You get the louse on her.
0:07:22 > 0:07:24- How are we going to do that?
0:07:25 > 0:07:28- Yiaow!
0:07:31 > 0:07:34- Alright, get ready, matey.
0:07:34 > 0:07:35- Penguin away!
0:07:35 > 0:07:37- Yargh!
0:07:43 > 0:07:45- OK, Mr Louse, this is it!
0:07:45 > 0:07:48- I don't know if I can make it.
0:07:48 > 0:07:50- For goodness' sake!
0:07:50 > 0:07:53- This is where you belong, - on a sperm whale!
0:07:54 > 0:07:56- I'm just too weak!
0:07:57 > 0:08:00- I don't know - how long I can keep her distracted!
0:08:00 > 0:08:03- I've run into some complications,
0:08:03 > 0:08:06- I'm going to have to perform - an emergency lousectomy!
0:08:06 > 0:08:08- Lousectomy?
0:08:08 > 0:08:09- Lousectomy?- - Lousectomy?
0:08:10 > 0:08:12- But I'll need my medical bag.
0:08:12 > 0:08:15- Ha-ha, - just tell me what you need, matey!
0:08:16 > 0:08:18- Tweezers. I need tweezers.
0:08:22 > 0:08:26- I can't see inside you, so let me - know when I'm getting close.
0:08:26 > 0:08:29- A little... a little to the left.
0:08:29 > 0:08:31- Steady.
0:08:32 > 0:08:35- Oooh, too far left. - Now, to the right.
0:08:35 > 0:08:37- Steady.
0:08:39 > 0:08:40- Almost got him.
0:08:40 > 0:08:45- Steady. And... gotcha!
0:08:49 > 0:08:51- Hey, hey, I'm home!
0:08:51 > 0:08:53- How do you feel?
0:08:53 > 0:08:57- Oh, now that I'm back on a whale, - I feel great! Thanks, Doc!
0:08:58 > 0:08:59- And what about you?
0:08:59 > 0:09:01- And what about you?- - I feel great!
0:09:01 > 0:09:03- The louse is on the whale.
0:09:04 > 0:09:06- I repeat, the louse is on the whale.
0:09:07 > 0:09:09- Both he and sponge are doing fine.
0:09:09 > 0:09:10- Both he and sponge are doing fine.- - Great work.
0:09:10 > 0:09:13- Fascinating! - Another example of commensalism.
0:09:14 > 0:09:17- The louse gets a home - and the whale doesn't mind at all.
0:09:18 > 0:09:22- She does mind us being this close - to her baby. We need to leave.
0:09:22 > 0:09:24- Everybody, ready?
0:09:25 > 0:09:26- Ready, matey!
0:09:27 > 0:09:28- Clear!
0:09:29 > 0:09:30- Gotcha!
0:09:40 > 0:09:43- And stay away!
0:09:47 > 0:09:49- It's good to be back!
0:09:59 > 0:10:02- Easy now. Come on, no shoving. - One at a time, please.
0:10:03 > 0:10:05- Hello there, come on in now.
0:10:05 > 0:10:07- Oh, good to see you again.
0:10:07 > 0:10:10- Oh, good to see you again.- - Ah, home sweet home! Ha, ha!
0:10:11 > 0:10:13- Look at the broken rocks.
0:10:13 > 0:10:16- The whale brushed - against the reef here.
0:10:16 > 0:10:21- The louse must have fallen off when - the whale knocked the sponge loose.
0:10:21 > 0:10:26- Now they're both back where - they belong, healthy and happy.
0:10:26 > 0:10:29- Excuse me, - got room for a few more in there?
0:10:29 > 0:10:34- Of course, as long as you're not - a whale louse, I don't mind at all!
0:10:35 > 0:10:38- Come on, fellas, in we go!
0:10:42 > 0:10:44- I felt that.
0:10:58 > 0:10:58- .
