0:00:46 > 0:00:48Hello, fishy! Is that your name?
0:00:48 > 0:00:50FISH GULPS
0:00:51 > 0:00:53What? Are you talking?
0:00:54 > 0:00:58I can't hear you through the bowl. Can you hear me?
0:00:59 > 0:01:01FISH GULPS
0:01:01 > 0:01:04How do you stay underwater for so long?
0:01:06 > 0:01:07MESSY SIGHS
0:01:07 > 0:01:11If you won't tell me, when you need to know go to Okido.
0:01:21 > 0:01:27- Hi, Zoe. Hi, Felix. Wow! Cool stick. - Hey, Messy! That's my best stick.
0:01:27 > 0:01:30I found it in Okido forest.
0:01:30 > 0:01:34You can play with it as long as you're careful.
0:01:35 > 0:01:38Yeah, best stick ever.
0:01:38 > 0:01:41It goes in the treasure box, Messy.
0:01:41 > 0:01:45- It's where we keep all our favourite finds.- Oh!
0:01:45 > 0:01:46What's that?
0:01:48 > 0:01:51It's something I found yesterday.
0:01:51 > 0:01:52I like it.
0:01:52 > 0:01:57Hey, there's a hole. I could add this to my necklace.
0:01:57 > 0:02:03- It's not from a necklace. I think it's an old coin or a medal.- Shiny.
0:02:03 > 0:02:06- Where did you find it, Felix?- On the beach.
0:02:06 > 0:02:12And if you found one, there might be more. More necklaces.
0:02:12 > 0:02:14More medals.
0:02:14 > 0:02:20- More shiny round things.- Let's go and look.- Ah! Balabalaboomboom!
0:02:21 > 0:02:23MESSY WHISTLES
0:02:27 > 0:02:30Let's skeedoodle Oki-doodle.
0:02:36 > 0:02:42- I can't see any buried treasure. - Oh, no. Me neither. Messy?
0:02:42 > 0:02:48- I'm hot and sticky and sandy. Isn't it great?- No, it's not.
0:02:48 > 0:02:50We've looked everywhere.
0:02:50 > 0:02:53I don't think there are any more golden necklace beads.
0:02:53 > 0:02:58- Or medals.- Or shiny round things. - On this whole beach.
0:02:58 > 0:02:59ZOE SIGHS
0:02:59 > 0:03:02Maybe you found the only one, Felix.
0:03:02 > 0:03:04Yeah, except for the ones that crab has.
0:03:04 > 0:03:05BOTH: What?
0:03:07 > 0:03:12- Excuse me, crab, where did you get those?- Hey, Mr Crab, come back.
0:03:12 > 0:03:15- Quick, let's follow. - He runs like this.
0:03:18 > 0:03:20Oh, what do we do now?
0:03:20 > 0:03:22Hm?
0:03:22 > 0:03:23I know.
0:03:23 > 0:03:27Zim, Zam, it's Zoe. Can you come to the beach, please?
0:03:27 > 0:03:30OK, Zoe, we'll be right there.
0:03:37 > 0:03:41Hi, Zim. Hi, Zam. Look what Felix found.
0:03:41 > 0:03:45Then we saw a crab with another two. Do you know what it is?
0:03:45 > 0:03:48Ah, yes. Fascinating.
0:03:48 > 0:03:52Felix, you found a coin from old Okido days.
0:03:52 > 0:03:57It's hundreds of years old and made from solid gold.
0:03:58 > 0:04:00Solid gold.
0:04:00 > 0:04:03I better put it in the treasure box when we get home.
0:04:03 > 0:04:07Coins of this type are incredibly rare.
0:04:07 > 0:04:12They must have washed up on the beach after the big storm we had last week.
0:04:12 > 0:04:15But where could a coin like this come from?
0:04:15 > 0:04:17BOTH: A shipwreck.
0:04:17 > 0:04:20- A shipwreck.- Balabalaboomboom.
0:04:20 > 0:04:25And the shipwreck might be full of more old Okido treasures.
0:04:25 > 0:04:30Let's go swimming. I'll just put this down here for safe keeping.
0:04:30 > 0:04:33Where was I? Where are my armbands?
0:04:33 > 0:04:38Oh, no, no, no. A sunken shipwreck is deep underwater.
0:04:38 > 0:04:40Down on the seabed.
0:04:40 > 0:04:43You'd need to be underwater for a long time to get there.
0:04:43 > 0:04:45So let's go underwater.
0:04:45 > 0:04:48But you can't stay underwater for long enough
0:04:48 > 0:04:51because you can't breathe underwater.
0:04:51 > 0:04:52If you please, Zoom.
0:04:52 > 0:04:55You need oxygen to breathe.
0:04:55 > 0:05:00Oxygen is in the air around us and you use your lungs to breathe it.
0:05:00 > 0:05:03But if you're underwater for a long time you need special
0:05:03 > 0:05:08equipment to give you oxygen so you can breathe.
0:05:08 > 0:05:13- I'll make you diving suits.- Whoa! We're going diving for treasure.
0:05:13 > 0:05:14Hooray!
0:05:15 > 0:05:20- Hey, come back!- My coin! Crab took my coin.- Oh!
0:05:20 > 0:05:24Then we better follow it. To the Cloudship.
0:05:36 > 0:05:38Balabalaboomboom!
0:05:41 > 0:05:46We're swimming. We're swimming and flying and diving at the same time.
0:05:53 > 0:06:00Oh, wow! I've never been so deep underwater. It's beautiful.
0:06:01 > 0:06:03MESSY LAUGHS
0:06:03 > 0:06:06The fish are talking. Just like the fish back home.
0:06:06 > 0:06:09Bloop, bloop, bloop.
0:06:09 > 0:06:12Come and try on your diving suits.
0:06:12 > 0:06:18- Whee! - They're a bit tricky to walk in.
0:06:18 > 0:06:21You'll move fine once you're in the water.
0:06:21 > 0:06:23And the oxygen in the tanks will help you to
0:06:23 > 0:06:25breathe like you can on land.
0:06:25 > 0:06:27But goldfish don't wear all this stuff.
0:06:27 > 0:06:31And they stay underwater for ages. Why can't we?
0:06:31 > 0:06:36Look. Fish don't use lungs to breathe air like you.
0:06:36 > 0:06:39They can take oxygen out of the water using their gills
0:06:39 > 0:06:42under those flaps at the side.
0:06:42 > 0:06:49- But you can't do that.- So water is like air for them?- Lucky fish.
0:06:49 > 0:06:52But what about my coin? How will we find it?
0:06:52 > 0:06:56I wish I'd left it safely in my treasure box.
0:06:56 > 0:07:01It's OK, Felix. Zoom's metal detector will help us track it.
0:07:01 > 0:07:03Quick, Zoom's got a signal.
0:07:11 > 0:07:15- Where's my coin exactly? - It should be straight ahead of you.
0:07:15 > 0:07:19- There it is.- Wait, that's odd.
0:07:19 > 0:07:23Zoom's getting more than one metallic signal.
0:07:23 > 0:07:25I've almost got it.
0:07:25 > 0:07:26Bit closer.
0:07:27 > 0:07:29Ah! Come here.
0:07:30 > 0:07:33Nearly. Oh, no!
0:07:33 > 0:07:38- Hey!- Hey, wait! That's our coin. Can we have it back, please?
0:07:39 > 0:07:43It's OK. Zoom spotted another coin down here. Come on!
0:07:45 > 0:07:47I'm sure this one's mine.
0:07:47 > 0:07:49Careful.
0:07:51 > 0:07:56That keeps happening. It's like they're moving it away on purpose.
0:07:56 > 0:07:58It fell into that cave. Let's go.
0:08:02 > 0:08:06Uh-oh! I think the cave is actually someone's mouth.
0:08:06 > 0:08:09What? Someone has a mouth that big?
0:08:11 > 0:08:14- Oh!- Hello.- Hello, nice fishy!
0:08:16 > 0:08:21Look, Felix, your coin is too far to reach. Sorry, fishy.
0:08:21 > 0:08:24Watch it, she's closing her mouth again.
0:08:26 > 0:08:30I know what, "Ugh, ugh, ugh," means. It means the coin is stuck.
0:08:30 > 0:08:31We'll help her.
0:08:31 > 0:08:36- Won't we, Zoe.- Yes, we will. Zoom, can you make a grabber shape?
0:08:39 > 0:08:44Great! Zoom, quick grab the coin.
0:08:44 > 0:08:45Quick.
0:08:46 > 0:08:47ALL: Yay!
0:08:48 > 0:08:54You did it, Zoom. The fish is OK and I've got my coin back.
0:08:54 > 0:08:56Great work everyone.
0:08:57 > 0:08:59Oh, no you don't.
0:09:00 > 0:09:04Felix is right. It's like the little fish don't want us to have a coin.
0:09:04 > 0:09:06- Why?- Seems a bit greedy when they've got
0:09:06 > 0:09:10so many to play with in that old boat down there.
0:09:10 > 0:09:11ALL: What?
0:09:11 > 0:09:14- It's the shipwreck.- Let's go!
0:09:17 > 0:09:19This is amazing.
0:09:19 > 0:09:23A real shipwreck from old Okido times.
0:09:23 > 0:09:26Look, there's the crab.
0:09:26 > 0:09:31Hello, crab. Why are you putting more coins in that old box?
0:09:31 > 0:09:35Look! They're all doing it.
0:09:35 > 0:09:38They're bringing coins to the chest.
0:09:38 > 0:09:42The coins must have washed away in the storm and the sea
0:09:42 > 0:09:46creatures are finding them and putting them back where they belong.
0:09:46 > 0:09:48And they didn't want us to take the coins
0:09:48 > 0:09:51because they're trying to protect them here.
0:09:51 > 0:09:54Then my coin belongs down there too
0:09:54 > 0:09:56with all the others.
0:09:58 > 0:10:00Well done, Felix.
0:10:00 > 0:10:03We'll keep a close eye on the shipwreck from now on to make
0:10:03 > 0:10:05sure it's looked after.
0:10:05 > 0:10:08Treasures from the past should be protected.
0:10:08 > 0:10:11OK, Messy?
0:10:11 > 0:10:12Okey-do, Zim.
0:10:12 > 0:10:14See you back inside.
0:10:18 > 0:10:20That was an amazing adventure.
0:10:20 > 0:10:24And I can't wait to go home and tell the goldfish about it.
0:10:24 > 0:10:27- Happy swimming, everyone! - Bye, Messy.- Bye, Messy.
0:10:27 > 0:10:30And the shipwreck was full of treasure, Gill.
0:10:30 > 0:10:33I'm going to call you Gill because your gills
0:10:33 > 0:10:36help you breathe in water. Do you like your name?
0:10:36 > 0:10:37GILL GURGLES
0:10:37 > 0:10:39I think that's fish for yes. Bye-bye!
0:10:39 > 0:10:41Balabalaboomboom!
