0:00:47 > 0:00:49Hello!
0:00:49 > 0:00:53I like drinking water when I'm thirsty.
0:00:53 > 0:00:55But why do I have to drink it?
0:00:55 > 0:00:59What would happen to me if there was no water?
0:00:59 > 0:01:02Hmm. When you need to know, go to Okido!

0:01:17 > 0:01:20Ooh, wow! Are we going on an adventure?
0:01:20 > 0:01:25Even better! Zim, Zam and Zoom are taking us on a day trip as a treat.
0:01:25 > 0:01:28A surprise day trip!
0:01:28 > 0:01:31Ooh! Balabalaboomboom!
0:01:31 > 0:01:35We're just packing some things so that we're ready for anything.
0:01:35 > 0:01:39And, just in case, never leave home without a bath plug.
0:01:39 > 0:01:40DRUM STINGS

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