0:00:02 > 0:00:05Seven young explorers have taken on the biggest challenge
0:00:05 > 0:00:08of their lives, an epic adventure in the heart of Africa.
0:00:08 > 0:00:14It'll take them far from civilisation, encountering endangered wildlife.
0:00:14 > 0:00:15Such an adrenalin rush.
0:00:15 > 0:00:17Witnessing unique tribal ceremony.
0:00:17 > 0:00:22- Oh, wow.- And trekking where none have been before.- So amazing.
0:00:22 > 0:00:28They're following in the legendary footsteps of the great Scottish explorer Dr David Livingstone.
0:00:28 > 0:00:33And the demanding expedition will push them to the very limit.
0:00:33 > 0:00:35- It is a wake up call.- Horrible.
0:00:35 > 0:00:37I hate it.
0:00:37 > 0:00:41Have they got what it takes to be serious explorers?
0:00:43 > 0:00:45Coming up, awesome animals.
0:00:48 > 0:00:50- Oh, that was amazing. - Tensions in the team.
0:00:50 > 0:00:53No, you didn't, you didn't ask anyone.
0:00:53 > 0:00:55And keeping crocs out of camp.
0:00:55 > 0:00:58Shine your light in its face and back away slowly.
0:00:58 > 0:01:02Previously on Serious Explorers,
0:01:02 > 0:01:06the team completed four stomach-churning days at sea,
0:01:06 > 0:01:09sailing a traditional boat down the coast of Africa.
0:01:09 > 0:01:11I just can't stop throwing up.
0:01:13 > 0:01:15For Sian, the seasickness led to homesickness.
0:01:15 > 0:01:19I don't want to be here, but I do.
0:01:21 > 0:01:24Spirits were raised by an amazing welcome in the village of Pemba,
0:01:24 > 0:01:27where Livingstone himself made landfall.
0:01:28 > 0:01:32This is really strange, cos it's like we're celebrities.
0:01:32 > 0:01:36And the explorers were guests of honour at an astonishing tribal display.
0:01:36 > 0:01:40- I've never seen anything like it. - It's just incredible.
0:01:45 > 0:01:48It's day six of the Livingstone expedition and the young explorers
0:01:48 > 0:01:53are about to leave the coast and head into deepest Tanzania.
0:01:53 > 0:01:58Before they go, expedition leaders Ben and Polly have something special to show them.
0:01:58 > 0:02:03Evidence that Livingstone set off from this exact spot in 1866.
0:02:03 > 0:02:06He began his last journey from here.
0:02:06 > 0:02:08Yes, he came through this place where we're standing now.
0:02:08 > 0:02:12He made landfall here before going on into the heart of Africa.
0:02:14 > 0:02:17It was to be Dr Livingstone's final expedition,
0:02:17 > 0:02:20heading into uncharted territory in Tanzania.
0:02:20 > 0:02:25With no vehicles or trains, he had to walk vast distances, but
0:02:25 > 0:02:28he had no doubts about the positive effects of so much trekking.
0:02:28 > 0:02:30"Much hard work is involved,
0:02:30 > 0:02:36"but no-one can truly appreciate rest unless he has undergone severe exertion."
0:02:38 > 0:02:43Livingstone trekked west from Pemba before eventually ending his travels
0:02:43 > 0:02:46several years later at Lake Tanganyika.
0:02:46 > 0:02:49With only a month in all for their expedition,
0:02:49 > 0:02:52the young explorers will today fly to the Selous Game Reserve,
0:02:52 > 0:02:54on a key part of Livingstone's route.
0:02:58 > 0:03:05In a couple of hours they cover a distance that took Livingstone six months.
0:03:05 > 0:03:08The Selous Reserve is the largest wilderness left in Africa,
0:03:08 > 0:03:13with huge unexplored areas, unchanged since Livingstone's time.
0:03:15 > 0:03:18What we're doing now is very, very special.
0:03:18 > 0:03:21There are very few places left in Africa that you can do genuine
0:03:21 > 0:03:25foot safaris and experience Africa on foot.
0:03:25 > 0:03:28It's a very, very serious environment.
0:03:28 > 0:03:31I'm kind of nervous, but I'm excited at the same time, because
0:03:31 > 0:03:35obviously, we've never been anywhere like this before.
0:03:35 > 0:03:38It's just a short trek of half an hour to camp, but from now on,
0:03:38 > 0:03:43wherever they go, they'll be protected by experienced guides carrying guns.
0:03:43 > 0:03:50The reason I'm speaking in hushed tones is we heard an elephant out in that direction.
0:03:50 > 0:03:53And there's evidence of wildlife everywhere they look.
0:03:53 > 0:03:56This is eland, yes? Which is a big, big antelope.
0:03:56 > 0:04:01The explorers will be constantly on the move in the Selous Reserve, making camp each night.
0:04:01 > 0:04:04But as it's their first day in the bush,
0:04:04 > 0:04:09- tonight's camp has been set up for them in advance.- Hey, hey, hey.
0:04:09 > 0:04:11- Yeah, camp.- Check it out.
0:04:11 > 0:04:12Home sweet home.
0:04:12 > 0:04:15We've got four two-man tents.
0:04:15 > 0:04:17Cassie and Sian, that's your tent.
0:04:17 > 0:04:22With only three girls in all, it means Ashleigh gets a tent to herself.
0:04:22 > 0:04:25Ashleigh, you lucked out.
0:04:25 > 0:04:27- OK? That is your tent.- That's fine.
0:04:27 > 0:04:31- All right?- I'll just be the outcast of the group.- I'll swap.
0:04:31 > 0:04:35The camp toilet is unlike anything they've ever used before.
0:04:35 > 0:04:38- Can anyone guess what that is? - A jaw of an animal.
0:04:38 > 0:04:40- A wishbone? - It's the jaw of an elephant.
0:04:40 > 0:04:45And as you can see, it makes the perfect loo seat.
0:04:45 > 0:04:47I don't want to see any dribbly bits down the jaw.
0:04:47 > 0:04:50Please, no, yes.
0:04:52 > 0:04:54To survive in this extreme environment,
0:04:54 > 0:04:58there's a huge amount to learn before they begin trekking tomorrow morning.
0:04:58 > 0:04:59- Buffalo?- Yes.
0:04:59 > 0:05:01Why do you reckon it's a buffalo?
0:05:01 > 0:05:03Because it's a big, cloven hoof.
0:05:05 > 0:05:09They'll get drinking water straight from the river, purifying it with chemicals.
0:05:09 > 0:05:11Five drops, perfect.
0:05:13 > 0:05:17They also learn how to safely use dangerous knives called machetes,
0:05:17 > 0:05:18an essential tool in the bush.
0:05:21 > 0:05:24From scorpions to mosquitoes, many small creatures pose
0:05:24 > 0:05:30a serious threat and expedition doctor Fi has just experienced one of them.
0:05:30 > 0:05:35- Now this is something that's called a tick.- A tick?- Exactly. It's a blood-sucking parasite.
0:05:35 > 0:05:39The other doctor, Stephan, shows how to remove it.
0:05:39 > 0:05:44So we're going to get the head of the forceps underneath there and out it comes.
0:05:44 > 0:05:47- Can you see the jaws sticking out? - Oh, yes.
0:05:47 > 0:05:49The serious training highlights the alien world
0:05:49 > 0:05:52they'll have to cope with over the coming weeks.
0:05:52 > 0:05:55And Sian starts to find it all overwhelming.
0:05:55 > 0:05:58With her homesickness returning, assistant leader Polly takes her
0:05:58 > 0:06:02- aside for a heart to heart chat. - Oh, don't worry. - SHE SOBS
0:06:04 > 0:06:06You're finding it a bit difficult, aren't you? Yes?
0:06:06 > 0:06:08I'm just worried about
0:06:08 > 0:06:12moving about and that. Just that I'm not going to be able to do it.
0:06:12 > 0:06:15The first week is always the hardest, OK?
0:06:15 > 0:06:19Because you're in a different environment with different people.
0:06:19 > 0:06:21I'm just thinking about, like, home.
0:06:21 > 0:06:25- I know. - How easy everything is as well.
0:06:25 > 0:06:31Your mum will be thinking of you every minute of the day, incredibly proud
0:06:31 > 0:06:34of what you're doing and that is what you've got to think, OK?
0:06:34 > 0:06:37It's been a bit hard again.
0:06:37 > 0:06:40I've just been upset again.
0:06:40 > 0:06:42I feel really,
0:06:42 > 0:06:46just a bit silly because nobody else is being really emotional.
0:06:46 > 0:06:49I feel sorry for her, cos I'm not missing my family that much
0:06:49 > 0:06:54yet, but she obviously is and it must be hard for her.
0:06:54 > 0:06:57She is just homesick.
0:06:57 > 0:06:59I think she's finding it quite tough
0:06:59 > 0:07:04and actually it's been a breeze so far, so I'm slightly concerned.
0:07:09 > 0:07:13To explore in deepest Africa, Dr Livingstone relied on the knowledge
0:07:13 > 0:07:18of local people, taking a loyal team with him on every expedition.
0:07:18 > 0:07:23Their experience in the wild helped him live away from civilisation for years at a time.
0:07:26 > 0:07:28And the Serious Explorers expedition
0:07:28 > 0:07:30will also be accompanied by local tribes people.
0:07:30 > 0:07:34Guys, can I just introduce you to a few people?
0:07:34 > 0:07:38The men are from the Mnyati tribe.
0:07:38 > 0:07:46Now, these guys, Robert, Kumbi, Alexi, and Charlie, similar to Livingstone, are going
0:07:46 > 0:07:50to be our faithful Askaris for the duration of our expedition, OK?
0:07:50 > 0:07:53Askaris meaning "soldiers".
0:07:53 > 0:07:57The Mnyati tribesmen throw their spears with deadly accuracy,
0:07:57 > 0:08:01even using them to kill lions to protect their families.
0:08:01 > 0:08:06These guys have thrown spears since they were about four.
0:08:06 > 0:08:10The Mnyati are also experts at surviving in the bush.
0:08:10 > 0:08:12Watch this.
0:08:12 > 0:08:16And they show the explorers an extraordinary skill -
0:08:16 > 0:08:20how to light a fire using only the materials around them.
0:08:20 > 0:08:22We've just made a couple of holes on top of that piece of wood.
0:08:22 > 0:08:25Any hot coal that comes out of there
0:08:25 > 0:08:29will fall down into where all this very, very dry elephant dung is.
0:08:31 > 0:08:34Creating precious fire in this way
0:08:34 > 0:08:38is an ancient art passed down over thousands of years.
0:08:38 > 0:08:40They're adding in slightly thinner bits of wood
0:08:40 > 0:08:47- and slightly fatter bits of wood, so it's got something to take to. Whoa.- Wow.
0:08:47 > 0:08:51APPLAUSE
0:08:52 > 0:08:55The explorers find it's harder than it looks.
0:08:55 > 0:08:57It's really difficult to get even an ember going.
0:08:57 > 0:09:02I mean, when you're spinning the stick, it just falls out of the hole. It's really annoying.
0:09:04 > 0:09:09- Come on!- But with a little help from the Mnyati...- Get your face right down in there and blow it.
0:09:09 > 0:09:12- ..they finally succeed in creating fire.- Woo-hoo!
0:09:16 > 0:09:21With darkness fast approaching, it's time for a vital safety briefing.
0:09:21 > 0:09:24You have got to be aware that there are BIG animals out there
0:09:24 > 0:09:29- and night time is the time they come out to hunt and you are food. - Oh, great(!)
0:09:29 > 0:09:34South Western Tanzania is THE place for man-eating lions.
0:09:34 > 0:09:36- Is that where we are?- Yes.
0:09:36 > 0:09:38- Oh, lovely.- Yes!
0:09:38 > 0:09:44It is amazing in your tent at night, lying there and listening to the sounds. It is, it is fantastic.
0:09:44 > 0:09:47It was supposed to make us feel better
0:09:47 > 0:09:50and safe about all the animals that are coming
0:09:50 > 0:09:54into the camp, but it kind of made me feel more paranoid.
0:09:56 > 0:10:01And as they prepare for bed, their nerves are not helped by the sounds coming from the river.
0:10:04 > 0:10:08We heard some sort of noise but I don't know what it was.
0:10:08 > 0:10:10But it sounded big and scary.
0:10:10 > 0:10:14We just had a hippo about 30 yards away,
0:10:14 > 0:10:17literally sort of wandering through the trees and going... IMITATES HIPPO
0:10:17 > 0:10:22You could just hear everyone going, "What was that?"
0:10:22 > 0:10:24I don't want to go to bed.
0:10:24 > 0:10:30I'm so nervous. Everyone's got a pair they can snuggle up to and I've just got myself,
0:10:30 > 0:10:32just myself.
0:10:32 > 0:10:34I think they're slightly nervous.
0:10:37 > 0:10:38Good night, everyone.
0:10:47 > 0:10:51At first light, there's no sign of movement from the explorers,
0:10:51 > 0:10:53so leader Ben goes to wake them up.
0:10:53 > 0:10:55Wakey, wakey.
0:10:58 > 0:11:01- Oh...- How are we doing?- Good.
0:11:01 > 0:11:06- Sleep all right?- Yeah, me and Mitch dozed off so quickly.
0:11:08 > 0:11:11How are you doing, girls? You need to shake a leg, all right?
0:11:13 > 0:11:17Sleeping on her own, Ashleigh had a rather more disturbed night.
0:11:17 > 0:11:20Hello. I've been up for ages.
0:11:20 > 0:11:24- Since, like, since it was dark. - Did you hear anything in the night?
0:11:24 > 0:11:28Yes, like a lion or something. I don't know. It was just loud.
0:11:28 > 0:11:30And then I fell asleep again.
0:11:30 > 0:11:35I was just lying here and you could hear breaking sticks and noises and stuff.
0:11:35 > 0:11:38The team will be on the move now for almost two weeks,
0:11:38 > 0:11:43trekking in a completely wild area, just like Livingstone.
0:11:44 > 0:11:50That's roughly where we are now. This is the river. Our ultimate destination is here.
0:11:50 > 0:11:52- Tonight?- Tonight, yes.
0:11:54 > 0:11:56Today's four-mile hike is a lot shorter
0:11:56 > 0:11:59than they'll have to do in the coming days,
0:11:59 > 0:12:03enabling them to get used to trekking in 35-degree heat.
0:12:03 > 0:12:07They have to constantly drink through tubes as they walk,
0:12:07 > 0:12:09so they don't get dehydrated.
0:12:09 > 0:12:13The explorers are now deep in wild animal territory.
0:12:13 > 0:12:15That could be a warthog.
0:12:15 > 0:12:18Middle distance, moving right to left, yeah?
0:12:18 > 0:12:19I love warthogs.
0:12:29 > 0:12:31In the distance, they come across a herd of buffalo.
0:12:31 > 0:12:34The powerful animals are grazing peacefully,
0:12:34 > 0:12:37but they can be very dangerous if disturbed.
0:12:37 > 0:12:42WHISPERING: What's going to happen now is that Polly's going to take four of you now
0:12:42 > 0:12:46to try and get as close as you can get, as far as cover allows, OK?
0:12:46 > 0:12:49And you guys are going to be working hard because you're going to be on
0:12:49 > 0:12:53your bellies, crawling, yes, in cover, in the long grass.
0:12:53 > 0:12:54Good luck, guys.
0:12:56 > 0:12:59What the explorers are about to attempt
0:12:59 > 0:13:02is something David Livingstone's expedition did regularly.
0:13:02 > 0:13:05Stalking up close to animals was a chance to observe their behaviour
0:13:05 > 0:13:10at a time when little was known about many African creatures.
0:13:10 > 0:13:14And sometimes Livingstone would also kill them for food.
0:13:18 > 0:13:24Four of the young explorers go forward to try to get a closer look at the buffalo herd.
0:13:24 > 0:13:27For safety, they're led by an experienced armed guide.
0:13:27 > 0:13:29- Go in very slowly.- Yes.
0:13:29 > 0:13:34Nerves are on edge as the explorers creep closer.
0:13:36 > 0:13:40Sit down. Legs forward, sit down.
0:13:47 > 0:13:49They head directly into the wind,
0:13:49 > 0:13:53so the buffalo don't pick up their sound or scent.
0:13:53 > 0:13:55They can't smell us at all.
0:14:00 > 0:14:01OK, just really slowly.
0:14:10 > 0:14:15And at last, they get an unbelievable close-up view.
0:14:20 > 0:14:22The team hardly dare breathe.
0:14:26 > 0:14:30Finally the herd seem to pick up their scent and start to head away.
0:14:32 > 0:14:35- WHISPERING:- I underestimated how hard it would be
0:14:35 > 0:14:37crawling through all that soot on the floor,
0:14:37 > 0:14:39running through the bushes.
0:14:39 > 0:14:42- It's tiring.- It's incredible.
0:14:42 > 0:14:45I've never done anything like it before. It was so scary.
0:14:45 > 0:14:47That was incredible.
0:14:47 > 0:14:52Such an adrenalin rush to see them out in the wild and we're like tracking them.... There!
0:14:55 > 0:14:58Two buffalo have calmly returned to just a few metres away.
0:15:01 > 0:15:05And the explorers get their closest view of all.
0:15:06 > 0:15:10Two of them were literally in front of us and it was just a great feeling.
0:15:12 > 0:15:17You realise how powerful they are, and to get up so close,
0:15:17 > 0:15:20like 10 metres away, it was just absolutely amazing, I loved it.
0:15:20 > 0:15:25All the mud and the sweat and everything, it was just completely worth it, 100%.
0:15:25 > 0:15:29It was probably the best experience of my life.
0:15:29 > 0:15:33And the encounter has completely lifted Sian's spirits.
0:15:33 > 0:15:37At the start I was like, "Oh, no, we're not going to get close enough."
0:15:37 > 0:15:40I was getting all muddy and that. I'm quite proud
0:15:40 > 0:15:44of myself now because we got really close to a couple.
0:15:44 > 0:15:45That was not easy, guys.
0:15:45 > 0:15:47I really take my hat off to you all.
0:15:47 > 0:15:50What a treat. I mean, that is...
0:15:50 > 0:15:53That's extraordinary, honestly.
0:15:53 > 0:15:58It's been quite a day, and as the team approach their new campsite,
0:15:58 > 0:16:00it's just about to get even better.
0:16:00 > 0:16:06They spot a huge herd of hippos walking down a river.
0:16:06 > 0:16:07- Loads of hippos.- Wow.
0:16:10 > 0:16:12With the armed guides on hand,
0:16:12 > 0:16:16they're able to have a unique encounter with the extraordinary creatures.
0:16:24 > 0:16:27It's just incredible to be that close to a wild animal.
0:16:29 > 0:16:32The size of them - it's just awe-striking
0:16:32 > 0:16:35and it's amazing to see them naturally
0:16:35 > 0:16:38just swimming around, doing what they do.
0:16:38 > 0:16:40But the large expedition team
0:16:40 > 0:16:45unsettles a female guarding her young and she makes her feelings known.
0:16:48 > 0:16:50It's all right. Don't worry, you're fine.
0:16:50 > 0:16:52Relax, relax, relax.
0:17:02 > 0:17:05For good measure, just before sunset,
0:17:05 > 0:17:07they get their first fleeting glimpse
0:17:07 > 0:17:09of elephants in the distance.
0:17:09 > 0:17:11Guys, what a day you've been having.
0:17:11 > 0:17:17We've just been around the area and we've seen loads of hippo, loads of buffalo, ellies, you know.
0:17:17 > 0:17:19What a day.
0:17:22 > 0:17:25Today, absolutely incredible.
0:17:25 > 0:17:28The best day yet.
0:17:28 > 0:17:31You might see a TV programme - it's nothing like that.
0:17:31 > 0:17:35Being right next to it is wild and it was something really special.
0:17:37 > 0:17:42This is what we came here for, to see all the animals and follow in Livingstone's footsteps.
0:17:42 > 0:17:50It's just incredible to know what he went through and we're experiencing it as adventurers.
0:17:53 > 0:17:59But as the explorers head into their campsite, things are about to go rapidly downhill.
0:18:00 > 0:18:04The light is fading fast and there's lots to do to make camp.
0:18:04 > 0:18:10We need to get down and fill every single water container that you've got before night falls, yes?
0:18:10 > 0:18:14There's absolutely no way that we can be messing around down by the water come nightfall.
0:18:14 > 0:18:20For the first time, the seven serious explorers are responsible for all the tasks around camp,
0:18:20 > 0:18:24including making supper for the entire expedition.
0:18:24 > 0:18:26James quickly gets stuck in.
0:18:26 > 0:18:29I quite like cooking, actually.
0:18:29 > 0:18:31It's really good fun.
0:18:31 > 0:18:34Yes, it's nice to be able to get all the smells and the aromas.
0:18:34 > 0:18:39While he takes on the vegetable main course, the others are left cooking the maize.
0:18:39 > 0:18:41The mixture's really difficult.
0:18:43 > 0:18:48We don't want to cook it because it's really hard to stir but we don't want to eat it either,
0:18:48 > 0:18:50so I don't even know why we're doing it.
0:18:50 > 0:18:55James is the most experienced of the young campers and he prides himself on his outdoor skills.
0:18:55 > 0:18:58To be honest, I don't really need help.
0:18:58 > 0:19:01If I need it, I will ask,
0:19:01 > 0:19:06at a later time and they have been chopping up the vegetables, so they have done something.
0:19:06 > 0:19:10It's not like I'm doing everything, although I am doing the majority of the work.
0:19:10 > 0:19:15But his enthusiasm to take on so much is actually upsetting other members of the team.
0:19:15 > 0:19:18Well, I think I was supposed to be cooking,
0:19:18 > 0:19:21but I don't know, James kind of stopped me and said, "No, I want to do it."
0:19:21 > 0:19:24James was just being a wee bit annoying.
0:19:24 > 0:19:27He was really getting on my nerves.
0:19:27 > 0:19:30He has to get his own way and he has to be leading.
0:19:30 > 0:19:34He really doesn't accept anyone else trying. He'll do it all himself
0:19:34 > 0:19:37and he'll complain about how no-one's actually helped.
0:19:37 > 0:19:44James heads off to record his daily video diary, completely unaware that others are annoyed with him.
0:19:44 > 0:19:47I'm doing the cooking for the group
0:19:47 > 0:19:50and the group seem to like that and I do as well,
0:19:50 > 0:19:52so I'd better get back to that.
0:19:52 > 0:19:58Unfortunately, while he's away, no-one has kept an eye on the main course.
0:19:58 > 0:20:04We thought we'd make really nice vegetables and now they're all burnt and stuck to the bottom.
0:20:07 > 0:20:12The explorers' first attempt at supper is a disaster.
0:20:12 > 0:20:14Probably the worst meal I've ever had in the bush.
0:20:14 > 0:20:16It's charcoal!
0:20:16 > 0:20:18It's pure charcoal.
0:20:18 > 0:20:20Shocking.
0:20:20 > 0:20:22Nice, David?
0:20:22 > 0:20:28I felt really bad because the Mnyati, they had to eat
0:20:28 > 0:20:31and we hadn't provided them with good enough food cos it just tasted inedible -
0:20:31 > 0:20:33honestly, it was horrible.
0:20:33 > 0:20:41Tonight, I don't know what's gone on, but it's hideous, yes? And all those veggies burned to a cinder.
0:20:41 > 0:20:46I know it's your first time doing it, but those pots now are irretrievable.
0:20:46 > 0:20:49Some of the group feel they're being blamed unfairly
0:20:49 > 0:20:52and that James should take most of the responsibility.
0:20:52 > 0:20:55Fine! Go and do it yourself then.
0:20:55 > 0:20:58But you didn't give us a chance. You just take on the role without asking.
0:20:58 > 0:21:01- I asked if you wanted.- No, you didn't, you didn't ask anyone.
0:21:01 > 0:21:04- No, of course I didn't ask anyone. - Exactly!
0:21:04 > 0:21:10Almost a week into the expedition, it's the first real sign of friction in the team.
0:21:10 > 0:21:16He's saying that none of us wanted to do it, but he didn't give us a chance to do it.
0:21:16 > 0:21:18He just takes on the role.
0:21:18 > 0:21:21- Ali? Will you cook?- Yes.
0:21:21 > 0:21:22- Thank you.- I'll cook tomorrow.
0:21:25 > 0:21:27Camping every night in the wild,
0:21:27 > 0:21:31David Livingstone's men had their routine down to a fine art,
0:21:31 > 0:21:37with everything geared around making him as comfortable as possible and protecting him from wild animals.
0:21:37 > 0:21:44"Each person knows the station he is to occupy, with the post of honour at the fire at the front of the tent."
0:21:46 > 0:21:50And the young explorers are about to find out why Livingstone insisted
0:21:50 > 0:21:53- on guards staying awake through the night.- Look at this, guys.
0:21:53 > 0:21:58They're alarmed to discover their camp is close to a river full of crocs.
0:21:58 > 0:22:00A crocodile just there. You can just see its eyes.
0:22:00 > 0:22:03Oh, yes! You can see the body.
0:22:03 > 0:22:05It's massive.
0:22:05 > 0:22:10When you shine a bright torch on them, you can actually see them under the water, if it's shallow water.
0:22:10 > 0:22:12You can see the length of their bodies.
0:22:12 > 0:22:16- There's another two here.- There's a really skinny one right there, look.
0:22:16 > 0:22:20- See that eye?- Yes. - Those eyes are moving.
0:22:20 > 0:22:23If you fell in there, they would grab you
0:22:23 > 0:22:26and they'd probably twist you round
0:22:26 > 0:22:29and they'd maybe store you for a later feed.
0:22:29 > 0:22:32So they have a little area where they store food?
0:22:34 > 0:22:40It gives you a fairly good sort of reason for having a wash before dark, doesn't it?
0:22:40 > 0:22:42It was just too close for comfort.
0:22:42 > 0:22:45And now they know we're here.
0:22:45 > 0:22:48And I'm just a wee bit worried.
0:22:48 > 0:22:53I think we'll be all right. We've got lots of fires lit around us.
0:22:53 > 0:22:58We're making a lot of noise. To be honest, the crocs aren't coming up here, they're staying in the water.
0:22:58 > 0:23:03It's actually the hippos that would probably be worrying me a little bit more.
0:23:03 > 0:23:06Surrounded by so many dangerous creatures,
0:23:06 > 0:23:11the leaders decide the team will have to take turns to do a night watch.
0:23:11 > 0:23:13What we're going to be going, is we're going to have a sentry duty
0:23:13 > 0:23:17all through the night to make sure that we're safe here.
0:23:17 > 0:23:20After a long, hard day, it's a real blow.
0:23:20 > 0:23:25We've just been told we're doing shifts and we're only getting four hours' sleep.
0:23:25 > 0:23:29I'm a wee bit worried about tomorrow now.
0:23:29 > 0:23:32I guess we're going to have to grin and bear it.
0:23:32 > 0:23:36The team have a spooky night ahead.
0:23:36 > 0:23:40Working in twos and threes, each shift is joined by a Mnyati guard.
0:23:40 > 0:23:44Every now and again in the stream, you can see little eyes glancing at you,
0:23:44 > 0:23:47so you've got to keep a track of where they are
0:23:47 > 0:23:49so they don't get too close to camp.
0:23:49 > 0:23:51Just like Livingstone's men,
0:23:51 > 0:23:56they also keep the camp fire burning to put off animals from coming near.
0:23:58 > 0:24:02After their hour's shift James and Matt wake the next team.
0:24:02 > 0:24:06- Hey, guys, wake up.- What time is it?
0:24:06 > 0:24:08- 12 o'clock.- Come on, Ali.
0:24:09 > 0:24:11- David. - David, up you get mate, come on.
0:24:11 > 0:24:15As soon as possible because we gave you an extra five minutes of sleep, OK?
0:24:15 > 0:24:17Get up, get up, get up.
0:24:17 > 0:24:22It's the first night, so they've got to understand that we're a little bit slow.
0:24:22 > 0:24:25But Ben is not amused.
0:24:25 > 0:24:28It's now quarter past midnight and
0:24:28 > 0:24:31you're actually, in effect, only going to do now
0:24:31 > 0:24:34three-quarters of what you should've done.
0:24:34 > 0:24:35- This is not a joke.- Yes.
0:24:35 > 0:24:37You've seen the amount of crocodiles
0:24:37 > 0:24:41that are in that pool down there. We need to be on top of things.
0:24:43 > 0:24:46The night seems never-ending.
0:24:49 > 0:24:51Ashleigh, hello.
0:24:51 > 0:24:53It's your turn now.
0:24:55 > 0:25:01If you see anything, shine your big light in its face and back away slowly, yes? Just don't run.
0:25:03 > 0:25:06It's quite eerie.
0:25:06 > 0:25:09I'm really scared of finding like a pair of eyes
0:25:09 > 0:25:11just looking at me. Oh!
0:25:12 > 0:25:16But the sentry duty does the trick and the animals stay away.
0:25:21 > 0:25:23Termites all over my boots.
0:25:23 > 0:25:26By morning, the team are shattered.
0:25:29 > 0:25:32I'm really tired and I did not sleep enough.
0:25:34 > 0:25:36Ashleigh's feeling very emotional.
0:25:36 > 0:25:42In her exhaustion, last night's argument with James is upsetting her more than ever.
0:25:42 > 0:25:46All of last night, it's just like the whole dinner thing.
0:25:48 > 0:25:52And then... I'm annoyed... I just get on with it.
0:25:54 > 0:25:57But leader Polly feels it needs to be sorted out straightaway.
0:25:57 > 0:26:00- So he's a bit bossy?- Yeah.
0:26:00 > 0:26:02I can't stand him at the moment.
0:26:02 > 0:26:06He just takes the role himself without asking anyone.
0:26:06 > 0:26:10OK, so maybe we need to have a chat with him.
0:26:10 > 0:26:15James still has no idea he's upset Ashleigh so much.
0:26:15 > 0:26:19I think you've just got to be a little bit aware and conscious
0:26:19 > 0:26:23of what you're saying. You have to try not to hurt people's feelings too much.
0:26:23 > 0:26:26- Yes.- Yes? Does that make sense?
0:26:26 > 0:26:29- I really didn't think I did. - I know you didn't. I know.
0:26:29 > 0:26:34It's good to have a leader, it's good to have someone saying, "Right, do this, do that, do this."
0:26:34 > 0:26:38But I think you've got to be slightly careful when it all goes to rat poo
0:26:38 > 0:26:40that you take the blame as well as the others, yes?
0:26:40 > 0:26:44I didn't think she was feeling too bad, she was joking around.
0:26:44 > 0:26:46But maybe she was, so...
0:26:48 > 0:26:51He decides to swallow his pride and try to clear the air.
0:26:51 > 0:26:53Sorry, Ashleigh.
0:26:53 > 0:26:57- It's fine.- I didn't think that you were feeling bad...
0:26:57 > 0:27:02- Maybe I'll try and be a bit more considerate next time.- Yeah.
0:27:02 > 0:27:05- Ashleigh, why don't you look at him? He is saying sorry.- I am, I just said OK.
0:27:05 > 0:27:08Give him a hug.
0:27:08 > 0:27:10- Sorry.- It's all right.
0:27:12 > 0:27:16The leaders know the importance of sorting out disagreements quickly.
0:27:16 > 0:27:20With things getting tougher by the day, the explorers will only succeed
0:27:20 > 0:27:22by pulling together as a closely-knit team.
0:27:22 > 0:27:26It's going to get harder and harder and the small things
0:27:26 > 0:27:29at this moment in time become very big things later on,
0:27:29 > 0:27:33so it's absolutely vital just to nip it in the bud now.
0:27:33 > 0:27:35They've got to work together.
0:27:35 > 0:27:37Let's have a group hug!
0:27:39 > 0:27:42- Wait for me to join in! - Come on, Jamie.
0:27:47 > 0:27:50Next time on Serious Explorers, under pressure
0:27:50 > 0:27:54- as the going gets tough. - I just don't think I can do this.
0:27:54 > 0:27:59- A luxury treat for two. - It has a flushing toilet.
0:27:59 > 0:28:03- And first contact with home. - This is so exciting!
