0:00:39 > 0:00:42PARTY HORN TOOTS
0:00:42 > 0:00:43Hmm.
0:00:43 > 0:00:46Ah-ha! Woo!
0:00:46 > 0:00:48Ooh! Look what I found.
0:00:49 > 0:00:53HE GASPS It makes everything look bigger!
0:00:53 > 0:00:56Wow! Everything looks so big and...
0:00:56 > 0:00:58ARGH!
0:00:58 > 0:01:00A giant flying monster!
0:01:01 > 0:01:05Phew! It's not a monster. It's just a butterfly.
0:01:05 > 0:01:09But why does it look so big when I put this in front of my eye?
0:01:09 > 0:01:14And then normal size when I put it down again?
0:01:14 > 0:01:18Hmm. When you need to know, go to Okido!
0:01:26 > 0:01:27BOING!
0:01:27 > 0:01:29SPROING!
0:01:29 > 0:01:31BOING!
0:01:31 > 0:01:33Hiya, Zoe! Hiya, Felix!
0:01:33 > 0:01:37- BOTH:- Hi, Messy! - Smile!
0:01:37 > 0:01:41Hey, what are you doing? Where are you going? Can I come?
0:01:41 > 0:01:44He-he! we're going exploring in the forest.
0:01:44 > 0:01:48We'll get some great pictures with Felix's new camera.
0:01:48 > 0:01:51And you'll never guess who's taking us.
0:01:51 > 0:01:52Who? Who? Who?
0:01:52 > 0:01:56Tweedy the explorer.
0:01:56 > 0:01:58HE GASPS
0:01:58 > 0:02:02- Who?- Tweedy the explorer. She's famous.
0:02:02 > 0:02:06She was the first person to ever see the Speckled Freckled Frog.
0:02:06 > 0:02:08Oh, the what now? A frog?
0:02:08 > 0:02:13Hardly anyone's ever seen it, but we might get to if Tweedy's with us.
0:02:13 > 0:02:15Oh, uh, eh, hello, everyone.
0:02:15 > 0:02:18- Are you looking for the frog as well?- No.
0:02:18 > 0:02:21We're playing hide-and-seek with Zoom,
0:02:21 > 0:02:24but we've looked everywhere on the Cloudship.
0:02:24 > 0:02:26Zoom's very good at hiding.
0:02:26 > 0:02:31- Try looking through the binoculars again, Zam.- Oh! Binoculars!
0:02:31 > 0:02:35I love, love, love, love, LOVE binoculars!
0:02:35 > 0:02:37Um, what are they?
0:02:37 > 0:02:39Take a look.
0:02:39 > 0:02:42Oo-o-oh!
0:02:42 > 0:02:47They make everything look closer than they really are.
0:02:47 > 0:02:48How do they work?
0:02:50 > 0:02:53- Oh, hey-hey! - Oh, it's Zoom!
0:02:53 > 0:02:58How we see things is all about light and lenses.
0:02:58 > 0:03:03Light rays bounce off objects and send pictures of them to your eye.
0:03:03 > 0:03:07Your eye is a lens and helps to make sure the pictures are clear.
0:03:07 > 0:03:12Lenses can also be made from glass or plastic, and they're used to send
0:03:12 > 0:03:16the light rays a different way and make things look bigger or smaller.
0:03:16 > 0:03:21Things like binoculars, telescopes, magnifying glasses, all use lenses.
0:03:21 > 0:03:26Ooh, that's what I have at home! A magnifying glass.
0:03:26 > 0:03:28Zoom?
0:03:28 > 0:03:31Oh, Zoom's gone to hide again!
0:03:31 > 0:03:34OK. We're going to find him.
0:03:34 > 0:03:37Zoom! Coming, ready or not!
0:03:37 > 0:03:41- Bye!- Hello? Is anybody there?
0:03:41 > 0:03:43Oh, dear.
0:03:43 > 0:03:45I think I went the wrong way.
0:03:45 > 0:03:48- Oh, Tweedy!- Tweedy! - Over here, Tweedy!
0:03:48 > 0:03:51- Hello!- Hello!- Over here!- Over here!
0:03:51 > 0:03:54Ah. There you are.
0:03:54 > 0:03:58No wonder I couldn't see you. You were hiding.
0:03:58 > 0:04:00ALL: Huh?
0:04:00 > 0:04:03And I don't blame you with this snake in the garden.
0:04:03 > 0:04:05That's a hosepipe.
0:04:05 > 0:04:07I think she's joking.
0:04:07 > 0:04:10THEY LAUGH
0:04:10 > 0:04:13Oh, we're not worried about that silly old snake.
0:04:13 > 0:04:16Ha-ha! That's the spirit.
0:04:16 > 0:04:21I was just the same when I was a young girl. Just like you.
0:04:21 > 0:04:23Huh?
0:04:23 > 0:04:25THEY GIGGLE
0:04:25 > 0:04:31Right. Come along, then. Best foot forward and to the forest we go.
0:04:31 > 0:04:34CRASH!
0:04:34 > 0:04:38Nope. Sorry, eh, just testing.
0:04:38 > 0:04:41Ahem. This way.
0:04:46 > 0:04:51Now, we need to look for little froggy clues.
0:04:51 > 0:04:54Tracks. Footprints.
0:04:54 > 0:04:56- Tweedy!- Hello!
0:04:56 > 0:05:00Ah. Right. There you are. Ha-ha-ha!
0:05:00 > 0:05:03You do like this hiding game, don't you?
0:05:03 > 0:05:05Erm... Right.
0:05:13 > 0:05:17Here, froggy, froggy, froggy. Come to Messy.
0:05:20 > 0:05:23- Huh?- Here, froggy, froggy.- Froggy!
0:05:23 > 0:05:25Froggy, froggy!
0:05:25 > 0:05:27Here, froggy!
0:05:27 > 0:05:29- Here, froggy, froggy, froggy! - Froggy!
0:05:29 > 0:05:32Erm... Oh, no.
0:05:34 > 0:05:37Ah! There you are.
0:05:39 > 0:05:43No sign of the Speckled Freckled Frog of the Forest yet, Tweedy.
0:05:43 > 0:05:45Where's...? Where's Tweedy?
0:05:45 > 0:05:48Oh, no! We've lost her!
0:05:48 > 0:05:51How can she get lost? She's an explorer?
0:05:51 > 0:05:56Yes. But I don't think Tweedy can see very well.
0:05:56 > 0:06:01Don't you remember? She thought the hosepipe in the garden was a snake.
0:06:01 > 0:06:04And she thought I was a little girl.
0:06:04 > 0:06:05We have to find her.
0:06:05 > 0:06:08Oh, but she could be anywhere in the forest.
0:06:08 > 0:06:11Hmm. Well, what would Tweedy do?
0:06:11 > 0:06:17Hmm. She would look for clues, like, erm, footprints!
0:06:17 > 0:06:18Yes!
0:06:18 > 0:06:21Let's see if we can find hers.
0:06:21 > 0:06:22Come.
0:06:24 > 0:06:28- Hey, look! - Oh! They must be Tweedy's. Come on!
0:06:36 > 0:06:38- ZOE GASPS - Tweedy!
0:06:38 > 0:06:40Wait!
0:06:40 > 0:06:41Hello? Eh, oh...
0:06:43 > 0:06:46Oh, thank goodness we found you, Tweedy.
0:06:48 > 0:06:49Sit down here.
0:06:49 > 0:06:54Oh, thank you. I was getting worried I'd never find my way back to you.
0:06:54 > 0:06:56But you're a famous explorer.
0:06:56 > 0:06:58Aye, I was.
0:06:58 > 0:07:00But I'm not as young as I used to be
0:07:00 > 0:07:04and my eyesight isn't very good these days.
0:07:04 > 0:07:06I just didn't want to let you down.
0:07:06 > 0:07:09Oh, that's all right, Tweedy.
0:07:09 > 0:07:10We understand.
0:07:10 > 0:07:15- OVER LOUDSPEAKER:- Zim calling Zoom, wherever you are. We give up!
0:07:15 > 0:07:18Stop hiding and come back.
0:07:18 > 0:07:21It's over! You win!
0:07:21 > 0:07:24- Hey, guys!- Hey, Zim, Zam! Down here!
0:07:24 > 0:07:25Hello!
0:07:25 > 0:07:29Stand back, we're coming down.
0:07:29 > 0:07:32I bet Zim and Zam could help you, Tweedy.
0:07:32 > 0:07:36Hello, you three. Hello, Tweedy. Have you seen Zoom?
0:07:36 > 0:07:38No. Sorry.
0:07:38 > 0:07:40We'll help you look later.
0:07:40 > 0:07:43But, Zim, Tweedy's having trouble seeing things properly.
0:07:43 > 0:07:46Could those lenses you told us about help?
0:07:46 > 0:07:49Well, yes. They might.
0:07:49 > 0:07:52And not only that, they might help us find Zoom, too.
0:07:52 > 0:07:55Ahem. Ooh, if only there was some way
0:07:55 > 0:07:58to show you how lenses could help.
0:07:58 > 0:08:00ZOOM BEEPS
0:08:00 > 0:08:03- Yippee! - ZAM LAUGHS
0:08:03 > 0:08:08Sometimes, the lenses on your eyes don't work as well as they could.
0:08:08 > 0:08:13The light doesn't always hit the lens in the right way.
0:08:13 > 0:08:17But if you put another lens in front of the eye,
0:08:17 > 0:08:20you can change the way light hits the eye.
0:08:20 > 0:08:23And that helps the person to see better.
0:08:23 > 0:08:26To figure out what type of lens is best for each person,
0:08:26 > 0:08:28you need to do an eye test.
0:08:30 > 0:08:34Can you see more or less clearly with this lens?
0:08:35 > 0:08:37The same.
0:08:39 > 0:08:42Oh, now! Now that's much less blurry!
0:08:42 > 0:08:43What about now?
0:08:43 > 0:08:47Oh! I can see very clearly!
0:08:47 > 0:08:51And now I can make you a pair of glasses in the workshop.
0:08:52 > 0:08:54Ta-da!
0:08:56 > 0:09:00Balabalaboomboom! They look so cool!
0:09:00 > 0:09:02- ALL:- Yay!
0:09:04 > 0:09:09- TWEEDY GASPS - I can see everything, perfectly!
0:09:09 > 0:09:12Even you, little girl.
0:09:12 > 0:09:14THEY LAUGH
0:09:14 > 0:09:17I can see the leaves on the trees
0:09:17 > 0:09:21and those tiny froggy footprints.
0:09:21 > 0:09:24Did you just say "froggy footprints"?
0:09:24 > 0:09:27Oh, yes, I believe I did.
0:09:27 > 0:09:29Yes! We'll find it now!
0:09:29 > 0:09:32- Here, froggy, froggy, froggy! - Here, froggy!
0:09:32 > 0:09:34- Froggy!- Froggy!- Froggy!
0:09:34 > 0:09:36ZOE GASPS
0:09:38 > 0:09:42RIBBIT!
0:09:42 > 0:09:43- BOTH:- Aw!
0:09:43 > 0:09:45We just missed it.
0:09:45 > 0:09:51Oh, oh, well, they are quite shy. And very hard to find.
0:09:51 > 0:09:53So we didn't get a picture
0:09:53 > 0:09:55of the Speckled Freckled Frog of the Forest,
0:09:55 > 0:09:58but we can still get a photo of all of us!
0:09:58 > 0:10:01Yes. A photo.
0:10:01 > 0:10:07To remind me of the best exploring day I've had for a long time.
0:10:08 > 0:10:12Thanks to all of you and my new spectacles.
0:10:12 > 0:10:14Cheers!
0:10:14 > 0:10:16- ALL:- Smile!
0:10:16 > 0:10:17RIBBIT!
0:10:17 > 0:10:21- THEY CHEER - We got to see the frog after all.
0:10:21 > 0:10:25I've had a brilliant day, too! But I've got to get back home now.
0:10:25 > 0:10:27Bye, everyone!
0:10:27 > 0:10:28- ALL:- Goodbye, Messy!
0:10:30 > 0:10:31Hmm.
0:10:31 > 0:10:35Lenses can make things look bigger or clearer.
0:10:35 > 0:10:38Even if they're really far away!
0:10:38 > 0:10:39Bye-bye!
0:10:39 > 0:10:41Balabalaboomboom!
