0:00:51 > 0:00:55- That gator was the last swamp - creature that needed us today.
0:00:55 > 0:00:57- Time to head back home.
0:00:59 > 0:01:02- Pegwn, Cregynog, look at this.
0:01:03 > 0:01:06- There are all sorts of holes - in the swamp floor.
0:01:06 > 0:01:10- Those holes look like - crawfish burrows.
0:01:11 > 0:01:13- They dig them with their claws.
0:01:13 > 0:01:16- It's like a little village.
0:01:17 > 0:01:20- What are they doing?
0:01:20 > 0:01:22- Ooh, boy, our shells is itchy.
0:01:22 > 0:01:26- We use anything we can - to scratch these itches.
0:01:26 > 0:01:29- Let me see if I can help.
0:01:30 > 0:01:34- They're covered in spots. - What do you make of it, Pegwn?
0:01:35 > 0:01:39- It's called shell rot, but I've - never seen cases this bad before.
0:01:39 > 0:01:42- Someone must have made - everybody else sick.
0:01:43 > 0:01:47- Have any of you recently - travelled outside your village?
0:01:47 > 0:01:49- No way, no how. We stay put.
0:01:49 > 0:01:52- It's safer for us that way.
0:01:52 > 0:01:54- Did any strangers - visit your village?
0:01:54 > 0:01:58- There was a stranger - what come through a few days back.
0:01:58 > 0:02:03- Was right after when folks started - getting the spots and all sick.
0:02:03 > 0:02:05- Do you remember what he looked like?
0:02:05 > 0:02:08- Do you remember what he looked like?- - Hmm, he was a strange-looking fella.
0:02:08 > 0:02:10- Strange-looking in what way?
0:02:10 > 0:02:12- Strange-looking in what way?- - Lots of ways, I suspect.
0:02:12 > 0:02:17- I didn't pay much attention. - The swamp was so muddy that day.
0:02:17 > 0:02:19- I couldn't see my claw - in front of me.
0:02:19 > 0:02:21- Plus, I was falling off into my nap.
0:02:24 > 0:02:29- Oh! I can't even take a nice nap - on account of these terrible itches.
0:02:29 > 0:02:34- Every single crawfish is sick here. - This is a major medical emergency.
0:02:34 > 0:02:36- Pegwn to Captain Cwrwgl.
0:02:36 > 0:02:37- Cwrwgl here.
0:02:38 > 0:02:43- We have a village of crawfish here - with itchy spots on their shells.
0:02:43 > 0:02:45- I'll sound the Octoalert.
0:02:46 > 0:02:47- Octonots, to the launch bay.
0:02:56 > 0:03:02- A village of crawfish has come down - with a case of strange, itchy spots.
0:03:02 > 0:03:07- We must cure the crawfish - and stop the spots spreading.
0:03:07 > 0:03:11- Sounds like an all-hands-on-deck - situation.
0:03:11 > 0:03:15- Every Octonot and vegimal - is needed. To the swamp!
0:03:20 > 0:03:23- Alright, we'll need to split - into three teams.
0:03:23 > 0:03:28- Pegwn, Cregynog and Wythenyn, set - up a medical tent to treat the fish.
0:03:28 > 0:03:33- Dela, Ira, vegimals, make sure - nobody enters or leaves the village.
0:03:33 > 0:03:35- This'll stop the spread.
0:03:35 > 0:03:39- We'll search the swamp - for the mystery creature...
0:03:39 > 0:03:41- ..who made everyone sick - in the first place.
0:03:42 > 0:03:44- Octonots, let's do this.
0:03:45 > 0:03:49- Our job is to keep the sickness - from spreading if we can.
0:03:49 > 0:03:54- Just hang onto this rope, stay put, - and don't let anyone get past you.
0:03:55 > 0:03:56- Got it?
0:03:58 > 0:04:01- We need to try and find a cure - for the shell rot.
0:04:01 > 0:04:04- The poor crawfish are really itchy.
0:04:04 > 0:04:07- You can poke around my shell - all you want...
0:04:07 > 0:04:11- ..if it'll help you find a way - to stop this itching.
0:04:11 > 0:04:16- The shell rot is caused by a fungus, - extremely fast-growing.
0:04:16 > 0:04:18- No wonder it spreads quickly.
0:04:18 > 0:04:21- The shell rot is caused by a fungus.
0:04:22 > 0:04:24- A fungus? There's a fungus among us?
0:04:24 > 0:04:27- There's a fungus among us! - There's a fungus!
0:04:27 > 0:04:30- Yes, and we need to find a cure.
0:04:30 > 0:04:34- Luckily, I have just the thing - - anti-fungus cream.
0:04:36 > 0:04:38- Something moving.
0:04:38 > 0:04:42- Straight ahead. - It's another crawfish with spots.
0:04:42 > 0:04:45- He can't be from the village.
0:04:45 > 0:04:48- There's a good chance - he's the outsider...
0:04:48 > 0:04:51- ..that spread the shell rot - to the other crawfish.
0:04:52 > 0:04:56- Excuse us, we need to talk to you. - Please come out. We're here to help.
0:04:57 > 0:04:59- Only help we need - is with this itching.
0:04:59 > 0:05:02- Ugh, the missus has got it too.
0:05:02 > 0:05:06- Let me guess, a stranger - came through a few days back.
0:05:06 > 0:05:10- Next thing you know, you all - ended up with those itchy spots?
0:05:10 > 0:05:12- How do you know that?
0:05:13 > 0:05:15- The same thing happened - to some other crawfish.
0:05:15 > 0:05:17- Can you describe the stranger?
0:05:18 > 0:05:19- He was big.
0:05:19 > 0:05:22- You have swamp mud in your eyes - or something?
0:05:22 > 0:05:24- He was tiny, but he did swim fast.
0:05:25 > 0:05:28- The missus doesn't always - get the facts right.
0:05:28 > 0:05:30- The truth is, he swam slow.
0:05:30 > 0:05:34- Is there anything that you both - agree on about this stranger?
0:05:35 > 0:05:37- Yeah, he was kind of furry, - would you agree?
0:05:38 > 0:05:40- Well, yeah, maybe. - More hairy than furry,
0:05:41 > 0:05:45- At least what I saw of him, seeing - as how he was swimming so fast.
0:05:45 > 0:05:50- Thank you. We'll be back to help - as soon as we find a cure.
0:05:50 > 0:05:53- A lot of good that did us.
0:05:53 > 0:05:57- Well, they both agreed - he was hairy or furry.
0:05:57 > 0:05:59- I wonder how Pegwn's - getting on with a cure?
0:06:00 > 0:06:03- And now some anti-fungus cream - for you.
0:06:04 > 0:06:07- So far, so good. None of them - seem to be itching any more.
0:06:10 > 0:06:11- Oh! Never mind.
0:06:12 > 0:06:16- I don't know what else to try. - The anti-fungus cream usually works.
0:06:17 > 0:06:21- Is the muddy water the crawfish - swim in part of the problem?
0:06:21 > 0:06:25- Perhaps it would help to wash them - with fresh, clean water.
0:06:26 > 0:06:28- It's worth a try. Ira, come in.
0:06:28 > 0:06:31- Can you spare a couple - of the vegimals?
0:06:34 > 0:06:35- Sure can. Gwyddno, Meira.
0:06:36 > 0:06:38- I need them to go to the Octopod...
0:06:38 > 0:06:43- ..and bring back some fresh water - from the kitchen sink.
0:06:43 > 0:06:46- Hear that? Fresh water.
0:07:07 > 0:07:11- Mystery critter up ahead, - Captain, and he's a furry one.
0:07:12 > 0:07:15- Bet it's that scallywag - we're looking for!
0:07:16 > 0:07:18- Wait! Hold it right there, matey.
0:07:22 > 0:07:24- We're looking for a creature...
0:07:24 > 0:07:27- ..who's been spreading - shell rot around the swamp.
0:07:27 > 0:07:29- Someone furry, like you.
0:07:29 > 0:07:31- Spreading shell rot? Ha!
0:07:31 > 0:07:34- I'm a nutria. - I don't even have a shell.
0:07:35 > 0:07:37- He doesn't have any spots, either.
0:07:37 > 0:07:39- Aye, but...
0:07:40 > 0:07:43- Something's tickling me feet. Hey!
0:07:43 > 0:07:46- Hey, yourself. - Look, he's getting away.
0:07:48 > 0:07:49- Stop, you!
0:07:50 > 0:07:52- Did you see the crab's shell?
0:07:52 > 0:07:55- Covered with spots. - And her claws were furry-looking.
0:07:56 > 0:07:57- She must be the one.
0:08:01 > 0:08:04- Looks like she's heading - to the crawfish village.
0:08:05 > 0:08:08- Why? She's already given everyone - there shell rot.
0:08:08 > 0:08:13- Something tells me - she has no idea where she's heading.
0:08:13 > 0:08:17- Well done, you two. Fresh water - straight from the Octopod sink.
0:08:20 > 0:08:23- Let's see if the fresh water - has any effect on the spots.
0:08:25 > 0:08:28- Yuck! This here water's salty.
0:08:30 > 0:08:31- Indeed.
0:08:32 > 0:08:37- It spilled and you refilled it - with water from the launch bay pool?
0:08:39 > 0:08:43- But that's ocean salt water. - Not fresh water.
0:08:43 > 0:08:49- I'm so sorry. I know you crawfish - only live in fresh water.
0:08:49 > 0:08:51- Your spots, they look better.
0:08:52 > 0:08:55- I don't feel - none of that itchiness no more.
0:08:55 > 0:08:59- Jumping jellyfish, the saltwater dip - seems to be the cure...
0:08:59 > 0:09:02- ..we've been seeking - for the shell rot fungus.
0:09:06 > 0:09:11- Dela, Ira, round up every crawfish - and bring them here for treatment.
0:09:18 > 0:09:21- Captain, - we've found a cure for the crawfish.
0:09:21 > 0:09:26- Wonderful. But, Pegwn, there's - a strange crab heading your way.
0:09:26 > 0:09:29- She's the creature - that caused the shell rot.
0:09:29 > 0:09:32- She could make everybody sick - all over again.
0:09:32 > 0:09:35- We have to catch her - and cure her, too.
0:09:35 > 0:09:38- We're working on it. - Wait, there she is, Captain.
0:09:40 > 0:09:42- I can't take it, I tell you!
0:09:43 > 0:09:45- Oh, I can't take this itching!
0:09:46 > 0:09:48- Easy, now. We're here to help.
0:09:48 > 0:09:52- Well, how about that, - a Chinese mitten crab.
0:09:52 > 0:09:56- She's not from the swamp at all. - She's an invasive species.
0:09:56 > 0:09:58- She doesn't belong here.
0:09:58 > 0:10:00- I'm a long way from home.
0:10:01 > 0:10:04- She must have got the shell rot - on her travels...
0:10:04 > 0:10:06- ..and spread it - when she passed through.
0:10:07 > 0:10:09- Do you think I like having this?
0:10:09 > 0:10:12- I just want to get rid - of this itch and go home.
0:10:13 > 0:10:15- I think we can help on both counts.
0:10:18 > 0:10:22- Thank you for curing us - of all them itches.
0:10:22 > 0:10:26- Oh, me too. Feels so good - to be rid of that itch.
0:10:26 > 0:10:28- There's no more fungus among us.
0:10:29 > 0:10:33- There's still a little fungus - among us. Two more patients for you.
0:10:34 > 0:10:36- The missus can go first. - She's got the most.
0:10:37 > 0:10:40- I've got the most? - You've got the most spots.
0:10:40 > 0:10:44- You got your facts all wrong. - I think you've got the most spots.
0:10:59 > 0:10:59- .
