0:00:40 > 0:00:42Planet Earth -
0:00:42 > 0:00:44a perfect place in many ways.
0:00:44 > 0:00:47But that doesn't stop us fiddling with it.
0:00:47 > 0:00:49Building, for instance.
0:00:49 > 0:00:51We are always building stuff all over the place.
0:00:51 > 0:00:55Houses, office blocks, even sand castles.
0:00:56 > 0:00:59I wonder, if we were to take a trip into space,
0:00:59 > 0:01:05would we find other beings who, like ourselves, just love to build?
0:01:05 > 0:01:08Ah. There we are, the Clangers' planet.
0:01:08 > 0:01:11Let's go and see what's going on, shall we?
0:01:13 > 0:01:15Well, it all seems very quiet.
0:01:15 > 0:01:17The Clangers must be down below.
0:01:19 > 0:01:21Hang on.
0:01:21 > 0:01:24What's that? What a strange-looking thing.
0:01:24 > 0:01:26I've not seen one of those before.
0:01:26 > 0:01:31Oh, it's just Small Clanger carrying a box.
0:01:31 > 0:01:32Silly old me!
0:01:34 > 0:01:36It's full of little blocks.
0:01:36 > 0:01:39I wonder what Small is going to do with them?
0:01:45 > 0:01:47Oh, he's building a tower.
0:01:47 > 0:01:49A tower of blocks.
0:01:51 > 0:01:53And here's a Froglet to cheer him on.
0:01:59 > 0:02:01Oh, dear.
0:02:01 > 0:02:05What's Small going to do now? He's too short to reach any higher.
0:02:16 > 0:02:17HE CALLS
0:02:22 > 0:02:24Ah! Here's Tiny.
0:02:24 > 0:02:26Perhaps she can help.
0:02:36 > 0:02:38Tiny's right.
0:02:38 > 0:02:40She can't reach the top of the tower either.
0:02:40 > 0:02:42She's shorter than Small.
0:02:48 > 0:02:50Very good teamwork.
0:02:50 > 0:02:53But shouldn't Tiny be standing on Small's shoulders?
0:02:57 > 0:02:59What's that?
0:02:59 > 0:03:00RUMBLING
0:03:03 > 0:03:05A great big block in the sky.
0:03:11 > 0:03:12Something is happening.
0:03:12 > 0:03:14POP!
0:03:16 > 0:03:19Oh-oh! The Froglet's not hanging around.
0:03:19 > 0:03:21RUMBLING
0:03:21 > 0:03:23Oh! Is it going to land?
0:03:23 > 0:03:26Maybe Tiny and Small should get out of the way
0:03:26 > 0:03:28until they see what happens.
0:03:30 > 0:03:34It's another block, a smaller block, and this one has landed.
0:03:44 > 0:03:48Goodness me! This isn't any old block.
0:03:48 > 0:03:50It's like a robot block.
0:03:50 > 0:03:52A robo-block?
0:04:02 > 0:04:04Hmm. Didn't think much of that.
0:04:07 > 0:04:08Yes, Tiny.
0:04:08 > 0:04:10It's very strange.
0:04:10 > 0:04:11I wonder what it's doing here?
0:04:31 > 0:04:32WHIRRING
0:04:36 > 0:04:37BEEPING
0:04:37 > 0:04:39It seems to like that bit of Clanger planet.
0:04:42 > 0:04:43Oh, no!
0:04:43 > 0:04:45DRILLING
0:04:45 > 0:04:47TINY AND SMALL SHOUT IN ALARM
0:04:57 > 0:05:00Small wants to know why the robo-block is
0:05:00 > 0:05:02digging into their planet.
0:05:02 > 0:05:04CHIRPING
0:05:08 > 0:05:11Oh, something is coming down from the big block.
0:05:11 > 0:05:13It looks like a scroll of some sort.
0:05:25 > 0:05:28It's a picture of the Clangers' planet
0:05:28 > 0:05:31with lots of blocks all over it.
0:05:36 > 0:05:38I think Tiny's right.
0:05:38 > 0:05:41The robo-block wants to make the Clangers' planet
0:05:41 > 0:05:43looks just like the picture,
0:05:43 > 0:05:45with great big blocks all over it.
0:05:45 > 0:05:46No, no, that will never do.
0:05:55 > 0:05:58Small is telling that it can't build stuff on this planet.
0:05:58 > 0:06:00It's their planet.
0:06:04 > 0:06:05Oh, how rude!
0:06:36 > 0:06:38WHIRRING
0:06:40 > 0:06:41WHIRRING SLOWS DOWN
0:06:44 > 0:06:46Oh, no.
0:07:06 > 0:07:09Yes, it can't dig up the music trees.
0:07:09 > 0:07:11They're precious.
0:07:13 > 0:07:16Tiny is going to show it why they are so precious.
0:07:16 > 0:07:18MUSIC TREES PLAY A LILTING TUNE
0:07:25 > 0:07:27Oh, yes.
0:07:27 > 0:07:30I think that robo-block rather likes the music.
0:07:33 > 0:07:36Now, hopefully,
0:07:36 > 0:07:37the robo-block will understand
0:07:37 > 0:07:39why the music trees must be left alone.
0:07:44 > 0:07:47Small thinks the robo-block wants some more music.
0:07:50 > 0:07:52But Tiny doesn't want to play it any more music.
0:07:55 > 0:07:58She thinks it's time for it to go back home.
0:08:06 > 0:08:09Oh! The robo-block seems sad.
0:08:14 > 0:08:16MUSIC TREES PLAY FIVE NOTES
0:08:20 > 0:08:22FIVE NOTES PLAY ONE BY ONE
0:08:29 > 0:08:33Small thinks the music trees are giving the robo-block a present.
0:08:33 > 0:08:35Five fine notes.
0:08:38 > 0:08:41Yes, Small's right.
0:08:41 > 0:08:43What kind music trees they are.
0:08:49 > 0:08:53Here you are - a gift from the music trees.
0:08:59 > 0:09:01What a wonderful present.
0:09:01 > 0:09:03Now it has music wherever it goes.
0:09:04 > 0:09:06THE FIVE NOTES PLAY
0:09:12 > 0:09:14Thank you, trees.
0:09:15 > 0:09:17THEY PLAY
0:09:35 > 0:09:37Nicely done!
0:09:48 > 0:09:51Now the robo-block has a present for Tiny.
0:09:57 > 0:09:59That's good advice from Small.
0:09:59 > 0:10:04He's told the robo-block to find another planet to build things on.
0:10:04 > 0:10:06Planets where no-one already lives.
0:10:17 > 0:10:21There goes robo-block, off to... who knows where? Ah...
0:10:24 > 0:10:27If music be the food of love, play on.
0:10:29 > 0:10:32Oh, how nice!
0:10:32 > 0:10:35I wonder, does it still want to make buildings?
0:10:35 > 0:10:39Perhaps, or perhaps it will simply make music instead.
