0:00:47 > 0:00:52- Hello! I like drinking water - when I'm thirsty.
0:00:53 > 0:00:55- But why do I have to drink it?
0:00:55 > 0:00:59- What would happen to me - if there was no water?
0:00:59 > 0:01:02- When you need to know, go to Ocido!
0:01:12 > 0:01:15- Hi, Sian! Hi, Dylan!
0:01:15 > 0:01:17- Hi, Blero!

0:01:35 > 0:01:40- And, just in case, never leave home - without a bath plug.

0:02:07 > 0:02:10- Off we go!
0:02:10 > 0:02:14- Please tell us where we're going. - Is it a forest?
0:02:14 > 0:02:15- No.
0:02:16 > 0:02:17- Um, a funfair?
0:02:17 > 0:02:18- Um, a funfair?- - Nope.
0:02:18 > 0:02:19- A museum.
0:02:19 > 0:02:20- A museum.- - No.
0:02:20 > 0:02:22- Oh, a playground.
0:02:22 > 0:02:23- Oh, a playground.- - No.
0:02:23 > 0:02:25- Is it a cinema? Is it a library?
0:02:26 > 0:02:28- No.
0:02:28 > 0:02:32- Is it a mountain? A fairground? - Is it somewhere I can dig?
0:02:32 > 0:02:35- No. Well, yes.
0:02:36 > 0:02:40- There's certainly lots of sand - where we're going.
0:02:40 > 0:02:43- Ooh! The beach! Yes!
0:02:43 > 0:02:45- No.
0:02:45 > 0:02:47- No.- - Oh, oh, I think I know. The desert?
0:02:48 > 0:02:50- Hooray!
0:02:50 > 0:02:52- Swn, your assistance, please.
0:02:52 > 0:02:56- The place we're going - is called Ocidoasis.
0:02:56 > 0:03:00- It is in the desert - but it's shady and green.
0:03:00 > 0:03:03- An oasis is a place - with its own underground river.
0:03:04 > 0:03:09- Which means there's enough water - for trees and other plants to grow.
0:03:09 > 0:03:14- The nicest fruit I've ever tasted - grows there. You'll love it!
0:03:14 > 0:03:18- Mmm, yum. Let's go to Ocidoasis!
0:03:18 > 0:03:21- Oci-go!
0:03:33 > 0:03:35- This sand is hot, hot, hot!
0:03:36 > 0:03:40- Ocidoasis is just over - this sand dune. Come on!
0:03:41 > 0:03:45- Oh! Is that the Ocidoasis?
0:03:49 > 0:03:51- There's no fruit!
0:03:51 > 0:03:53- And no water!
0:03:53 > 0:03:56- The Ocidoasis has dried up!
0:03:57 > 0:04:01- Oh, no! The oasis should be much - more green and shady than this.
0:04:01 > 0:04:03- Look, everyone!
0:04:03 > 0:04:05- Look, everyone!- - Camels.
0:04:05 > 0:04:09- They must use the Ocidoasis - for drinking water.
0:04:09 > 0:04:13- Do you think they've drunk - all the water from the Ocidoasis?
0:04:14 > 0:04:16- Hmm. I don't think so.
0:04:18 > 0:04:21- Camels drink lots of water - at one time...
0:04:21 > 0:04:25- ..and store it for long journeys - across the desert.
0:04:25 > 0:04:30- But even camels - couldn't drink a whole oasis.
0:04:30 > 0:04:34- These camels must have used up - all their stored water.
0:04:34 > 0:04:37- They must be very thirsty.
0:04:37 > 0:04:42- Let's look around and see if we - can find out what has caused this.
0:04:42 > 0:04:43- Hmm.
0:04:44 > 0:04:45- Ow!
0:04:45 > 0:04:47- That rock is prickly!
0:04:49 > 0:04:52- Oh, Blero. That's not a rock, - it's a plant called a cactus.
0:04:52 > 0:04:55- Or cacti if there's more - than one of them.
0:04:55 > 0:04:59- Oh, don't touch it, - it's got sharp spikes all over it.
0:05:00 > 0:05:04- Be careful, - there are lots of them around.
0:05:04 > 0:05:08- Do they have anything to do - with the Ocidoasis drying up?
0:05:08 > 0:05:09- Probably not.
0:05:09 > 0:05:12- Cacti can store water - for a long time...
0:05:12 > 0:05:16- ..so they don't need - as much water as other plants do.
0:05:16 > 0:05:20- If cacti and camels can go - a long time without water...
0:05:20 > 0:05:23- ..why is water so important?
0:05:23 > 0:05:25- Swn, your assistance, please.
0:05:25 > 0:05:28- All living things - need water to grow and live.
0:05:29 > 0:05:31- Humans and monsters need water.
0:05:31 > 0:05:35- Animals need water, plants need - water, fruit trees need water.
0:05:35 > 0:05:37- Everything needs water.
0:05:37 > 0:05:43- And, in fact, more than half - of your body is made of water.
0:05:44 > 0:05:45- Really?
0:05:45 > 0:05:47- Really?- - That's so cool!
0:05:47 > 0:05:50- You need to drink water - to stay healthy...
0:05:51 > 0:05:53- ..especially when it's hot and dry.
0:05:54 > 0:05:59- People and almost all other - creatures need water every day.
0:05:59 > 0:06:02- But because there isn't - much water in the desert...
0:06:02 > 0:06:07- ..some plants and animals are able - to store water in their bodies.
0:06:07 > 0:06:10- They still need to drink sometimes, - just like you do.
0:06:11 > 0:06:13- Sian, you should have some. - You too, Blero.
0:06:14 > 0:06:17- These plants and creatures - will need water soon.
0:06:17 > 0:06:21- We have to find out what's wrong - with the oasis and fix it.
0:06:22 > 0:06:25- Wow! Look! What are those?
0:06:26 > 0:06:29- They are the desert night lizards.
0:06:29 > 0:06:34- Usually they only come out at night - when it's cooler.
0:06:35 > 0:06:37- They must be very hot and thirsty.
0:06:37 > 0:06:39- Where are they going?
0:06:41 > 0:06:43- Come here, lizard!
0:06:44 > 0:06:45- Too quick for me!
0:06:45 > 0:06:48- Phew! They're so quick!
0:06:49 > 0:06:51- Maybe they're looking for water.
0:06:52 > 0:06:53- Huh?
0:06:55 > 0:06:58- It's OK, Dylan! They found some.
0:06:58 > 0:07:01- It's water!
0:07:01 > 0:07:05- Wow! My turn next! Me next! - Please, please, please!
0:07:06 > 0:07:10- Where's that water coming from? - It's like a leaky hosepipe.
0:07:10 > 0:07:12- That's it.
0:07:12 > 0:07:16- The underground river that feeds - the oasis must be blocked.
0:07:16 > 0:07:20- The pressure of the blockage - has meant it's sprung a leak.
0:07:20 > 0:07:23- How can a river - be underground anyway?
0:07:23 > 0:07:27- It's too hot on the ground - for the rivers to form.
0:07:28 > 0:07:32- Rainwater drips down through gaps - in the rocks, where it's cooler.
0:07:32 > 0:07:35- Water gathers together - and forms rivers...
0:07:35 > 0:07:38- ..which reach the surface - to make an oasis.
0:07:38 > 0:07:44- So if we find the blockage and clear - it, the oasis will fill up again.
0:07:44 > 0:07:49- Sam, is the underground excavator - still on the Cloudship?
0:07:49 > 0:07:51- Good idea, Dylan.
0:07:53 > 0:07:55- This should do the job nicely.
0:07:55 > 0:07:59- Bala-bala-boom-boom! - Can I drive? Please!
0:07:59 > 0:08:03- Go on, then, Blero. - And take Swn with you.
0:08:03 > 0:08:07- You need to follow the leak - and look for the underground river.
0:08:08 > 0:08:09- Bye, see you soon!
0:08:10 > 0:08:12- Bye-bye!
0:08:22 > 0:08:25- I can't see water anywhere.
0:08:25 > 0:08:30- Me neither. - Just lots of lovely dirt and sand.
0:08:30 > 0:08:35- Keep looking. It must be there - somewhere. Go down a bit.
0:08:36 > 0:08:38- OK, Sam. We're heading down now.
0:08:39 > 0:08:40- Bala-bala-boom-boom!
0:08:46 > 0:08:49- Yay! - Just ahead where it gets narrow.
0:08:50 > 0:08:51- It's blocked.
0:08:52 > 0:08:55- Hmm. I can unblock it.
0:09:17 > 0:09:18- Oh, well done.
0:09:24 > 0:09:26- We unblocked it, Sim.
0:09:27 > 0:09:30- So the camels and plants - won't be thirsty much longer.
0:09:31 > 0:09:33- Now you just need to fix the leak.
0:09:33 > 0:09:36- I have just the thing.
0:09:38 > 0:09:40- Told you this would be handy.
0:09:41 > 0:09:43- That's better.
0:09:45 > 0:09:48- Oh, Sam, you are right.
0:09:48 > 0:09:51- It is beautiful here.
0:09:52 > 0:09:56- Oh, the trees look better already.
0:09:56 > 0:10:02- I told you. - Ocidoasis is a very special place.
0:10:02 > 0:10:05- It will be more special - once the fruit grows again.
0:10:05 > 0:10:09- I can't wait that long. - Luckily, I brought my own snack.
0:10:14 > 0:10:18- Eating socks is thirsty work. - I need a drink.
0:10:18 > 0:10:21- But I've got water at home.
0:10:21 > 0:10:24- Time for me to go. Bye, everyone.
0:10:24 > 0:10:25- Bye, Blero!
0:10:26 > 0:10:30- Water is very, very important - for all living things.
0:10:30 > 0:10:33- You have to make sure - you drink enough water...
0:10:33 > 0:10:35- ..especially when you're hot.
0:10:38 > 0:10:40- Bye-bye!
0:10:40 > 0:10:41- Bala-bala-boom-boom!
0:10:59 > 0:10:59- .
