0:00:45 > 0:00:49Oh, this is the best mess I've ever made!
0:00:49 > 0:00:52Wow! HE GIGGLES
0:00:53 > 0:00:55Hey!
0:00:55 > 0:00:56What's going on?
0:00:56 > 0:00:57Hmm.
0:00:57 > 0:01:00Why did my light go off all on its own?
0:01:02 > 0:01:05When you need to know, go to Okido!
0:01:06 > 0:01:08He-he!
0:01:17 > 0:01:19MUSIC PLAYS
0:01:20 > 0:01:23What are Zoe and Felix up to?
0:01:23 > 0:01:26Hi, Zoe! Hi, Fe... Wow!
0:01:26 > 0:01:27BOTH: Hi, Messy!
0:01:27 > 0:01:28Ba-ba-ba!
0:01:28 > 0:01:32Hey, you're having a party. Without me!
0:01:32 > 0:01:33No, we're not!
0:01:33 > 0:01:38We're just warming up for our disco this afternoon.
0:01:38 > 0:01:43We've got to practise if we're going to keep up with Zim, Zam and Zoom.
0:01:43 > 0:01:48It's lots of fun. Come on, Messy. Join in!
0:01:48 > 0:01:49Oh, all right, then.
0:01:49 > 0:01:52I love disco dancing!
0:01:54 > 0:01:58MUSIC STOPS SUDDENLY Hey! What's going on?
0:02:02 > 0:02:04THEY GRUMBLE
0:02:08 > 0:02:12My beautiful cake! Oh, why!
0:02:12 > 0:02:15Come on, come on, come on!
0:02:15 > 0:02:17Come on!
0:02:17 > 0:02:20Nooo! What's the score? Oh, who won?
0:02:23 > 0:02:26The buttons aren't doing anything.
0:02:26 > 0:02:28Excuse me. Let me try.
0:02:28 > 0:02:31I'm an expert with buttons.
0:02:31 > 0:02:32Oh!
0:02:32 > 0:02:35I wonder why it isn't working.
0:02:35 > 0:02:38Hm. Maybe Zim, Zam and Zoom can help.
0:02:38 > 0:02:40MESSY WHISTLES
0:02:43 > 0:02:46Let's ski-doodle, Okidoodle!
0:02:56 > 0:02:58Hello?
0:02:58 > 0:03:01Ah, it's you three.
0:03:01 > 0:03:03Zim, where are those torches?
0:03:03 > 0:03:05We can hardly see a thing!
0:03:05 > 0:03:07Oh, no!
0:03:07 > 0:03:11Ouch! I think I found them.
0:03:11 > 0:03:15Oh! This is why we need to get organised.
0:03:15 > 0:03:17Why is it so dark?
0:03:17 > 0:03:18There's a power cut.
0:03:18 > 0:03:22And that means there's no electricity to power the main lights. See?
0:03:22 > 0:03:25What's electricity?
0:03:25 > 0:03:27Electricity is energy.
0:03:28 > 0:03:33Humans and monsters need food and water for energy and power,
0:03:33 > 0:03:38but lots of machines use electricity to move and make sounds,
0:03:38 > 0:03:41and give off light and heat.
0:03:41 > 0:03:44Oh! Our stereo stopped playing our favourite song.
0:03:44 > 0:03:46Does it need electricity to work?
0:03:46 > 0:03:48Yes, it does.
0:03:48 > 0:03:50What else needs electricity?
0:03:50 > 0:03:52Socks?
0:03:52 > 0:03:54No, not socks, Messy!
0:03:54 > 0:03:56If you please, Zoom.
0:03:56 > 0:04:00Everything that has a plug, like this, needs electricity.
0:04:00 > 0:04:04When they're plugged into a socket, the electricity makes them work.
0:04:04 > 0:04:10But remember only grown-ups are allowed to touch plugs and sockets.
0:04:10 > 0:04:15Wow! So many things need leck-trick-ery to work.
0:04:15 > 0:04:17- WHISPERS:- Electricity, Messy!
0:04:17 > 0:04:20That's what I said. Leck-trick-ery!
0:04:20 > 0:04:21FELIX GIGGLES
0:04:21 > 0:04:24So, that's why our stereo isn't working.
0:04:24 > 0:04:28Oh, but that means we can't have our disco this afternoon.
0:04:28 > 0:04:31Nooo! Ahh!
0:04:31 > 0:04:35We have to fix the electricity so everything can go back to normal.
0:04:35 > 0:04:39- But where does electricity come from?- Hmm.
0:04:39 > 0:04:43In Okido, we get our electricity from wind power.
0:04:43 > 0:04:46Wow! How does that work?
0:04:46 > 0:04:49This is a wind turbine.
0:04:49 > 0:04:53And these are the rotors at the very top.
0:04:53 > 0:04:58The wind blows and pushes the rotors round and round.
0:04:58 > 0:05:02The wind turbine turns the movement into electricity.
0:05:02 > 0:05:06It travels down cables and into plug sockets, to power the things
0:05:06 > 0:05:09we use everyday in Okido City.
0:05:09 > 0:05:13I've been working on an exciting experiment
0:05:13 > 0:05:15to make our own electricity.
0:05:16 > 0:05:18- Ta-da! - THEY ALL GASP
0:05:18 > 0:05:19Wow!
0:05:22 > 0:05:23- Ouch!- Oops!
0:05:23 > 0:05:29Oh, sorry, Zim. Some last-minute tinkering to do.
0:05:29 > 0:05:30Oh!
0:05:30 > 0:05:32I'm seeing nuts and bolts.
0:05:32 > 0:05:34Wow, cool!
0:05:34 > 0:05:37This is the best experiment ever.
0:05:37 > 0:05:39I haven't tested it yet.
0:05:39 > 0:05:42I need to find three people good at pedalling
0:05:42 > 0:05:45and I just can't think of any one.
0:05:45 > 0:05:47Hm. You never asked me!
0:05:47 > 0:05:49You can't reach the pedals, Zim.
0:05:49 > 0:05:52Oh! Pick us! We're good at pedalling.
0:05:52 > 0:05:56Wonderful. Hop on board, then.
0:05:56 > 0:05:59Yes! We've got super pedalling skills.
0:05:59 > 0:06:00THEY PANT
0:06:00 > 0:06:03But the... The bike's not moving?
0:06:03 > 0:06:07Your pedal power works just like the wind power.
0:06:07 > 0:06:10The wheels are like the rotors.
0:06:10 > 0:06:14When you push the pedals, they spin round and round.
0:06:14 > 0:06:17The spinning wheels give energy,
0:06:17 > 0:06:21and the dynamo makes it into electricity.
0:06:21 > 0:06:24Once it has enough, the light will come on.
0:06:24 > 0:06:28- ALL: Hooray!- We did it.
0:06:29 > 0:06:31ALL: Oh!
0:06:31 > 0:06:34Oh, you have to keep pedalling for the light to stay on.
0:06:34 > 0:06:37Yes. That's it. That's it.
0:06:37 > 0:06:39Well done.
0:06:39 > 0:06:44Now, I wonder if we can make enough electricity for all of Okido City?
0:06:44 > 0:06:48We can't make electricity for everyone with our legs.
0:06:48 > 0:06:51My legs are aching already.
0:06:51 > 0:06:53According to my calculations,
0:06:53 > 0:06:57you'd have to cycle at 100mph non-stop for ever.
0:06:57 > 0:06:58- What?- Huh?
0:06:58 > 0:07:01- Probably be easier just to sit in the dark.- OK, OK.
0:07:01 > 0:07:04Perhaps it's not my best idea.
0:07:04 > 0:07:08We need to find a way to get the electricity working again.
0:07:08 > 0:07:13OK, let's go and check the wind turbine.
0:07:13 > 0:07:14Good luck, everyone.
0:07:20 > 0:07:23Whoa! It's ginormous!
0:07:24 > 0:07:26The rotors are turning.
0:07:26 > 0:07:28So, why is there no electricity?
0:07:30 > 0:07:32Can you hear that?
0:07:32 > 0:07:35It's coming from over there.
0:07:35 > 0:07:37Hello!
0:07:37 > 0:07:40Hello, hello! Now, please don't touch anything.
0:07:40 > 0:07:44Only official Okido electricity engineers allowed to touch.
0:07:44 > 0:07:47Official Okido electricity engineers?
0:07:47 > 0:07:51Yes, we make sure that the turbine is clean and working
0:07:51 > 0:07:54so that Okido has electricity and power.
0:07:54 > 0:07:57But Okido doesn't have power!
0:07:57 > 0:07:59What?
0:07:59 > 0:08:00Er, that's impossible.
0:08:04 > 0:08:05The rotors are working,
0:08:05 > 0:08:09but the power must not be getting through to Okido.
0:08:09 > 0:08:11How do we fix it?
0:08:11 > 0:08:13I don't know.
0:08:14 > 0:08:16This has never happened before.
0:08:16 > 0:08:20And now we've been here all day spring cleaning.
0:08:20 > 0:08:21Spring cleaning?
0:08:21 > 0:08:25Er, what's that cable for?
0:08:25 > 0:08:27It takes the power from the rotors
0:08:27 > 0:08:31and changes it into electricity for Okido.
0:08:33 > 0:08:34Oh.
0:08:34 > 0:08:38Maybe it was unplugged for the spring clean?
0:08:38 > 0:08:40- It wasn't me! - It wasn't me, either!
0:08:40 > 0:08:43Don't look at me, that's all I'm saying.
0:08:43 > 0:08:46Who else could it be, for goodness' sake...
0:08:46 > 0:08:48Er... Excuse me!
0:08:48 > 0:08:50Do you think you could plug it back in, please?
0:08:50 > 0:08:52Oh, yes, yes.
0:08:52 > 0:08:53Of course.
0:08:56 > 0:08:58There. That should do it.
0:09:02 > 0:09:04Goal!
0:09:04 > 0:09:05Yes!
0:09:07 > 0:09:08Hooray!
0:09:16 > 0:09:18- Brilliant.- Thank you.
0:09:18 > 0:09:19BOTH: You're welcome!
0:09:19 > 0:09:21- ..I wasn't even there.- No, don't!
0:09:21 > 0:09:24Well, that fixes the power cut.
0:09:24 > 0:09:28- And Okido City will have electricity again.- Yes!
0:09:28 > 0:09:30Now we can have our disco.
0:09:30 > 0:09:33Let's ski-doodle, Okidoodle!
0:09:34 > 0:09:36I hope this works.
0:09:36 > 0:09:39It has to. I need to dance!
0:09:39 > 0:09:43Oh, well done, you three.
0:09:43 > 0:09:48Everything is working now the wind turbine is making electricity again.
0:09:48 > 0:09:50You've earned your disco.
0:09:50 > 0:09:53I've got my dancing shoes on!
0:09:53 > 0:09:56Ha-ha! Let's dance.
0:09:56 > 0:09:58- ELECTRONIC MUSIC - Yeah!
0:10:01 > 0:10:03Woo-hoo!
0:10:15 > 0:10:18Oh, this is a brilliant disco.
0:10:18 > 0:10:21But it's time for me to go home now.
0:10:21 > 0:10:24ALL: Bye, Messy!
0:10:24 > 0:10:29So, my light needs electricity to work.
0:10:29 > 0:10:33I'll play in the dark until the power comes back on.
0:10:34 > 0:10:37Hurray! The electricity's back on.
0:10:37 > 0:10:39Balabalaboomboom!
0:10:40 > 0:10:41Balabalaboomboom!
