Bobo White accidently breaks the gate to the skyhorsey stable after the Cloudbabies have gone to wake Moon, and the skyhorsies escape. Bobo tries to find them with the help of Fuffa Cloud and Little Star, without success. Bobo unwittingly helps to wake Moon and, with the help of Baba Yellow's fluteytoot, the skyhorsies return home safely.

Bobo White desperately wants to be a Cloudbaby and he thinks he's succeeded when he gets his hands on a pot of purple paint and paints Sun.

Baba Green can't cloud bounce like the others, and it makes him sad. But after bravely rescuing Bobo White, he becomes the best bouncer of all.

Baba Pink thinks she is being helpful when she creates a star chart to monitor each of the Cloudbabies' jobs, but in the process she forgets about her own jobs.

The Cloudbabies go on a picnic, taking lots of rainpears with them. After Bobo White feeds the rainpears to the skyhorsies, they fall into a deep sleep. How will the Cloudbabies get to do their chores now, without the skyhorsies or the skytrain to take them? It is up to Skydonk to save the day.

Fuffa sees an opportunity for mischief and suggests to each of the Cloudbabies that the door of Cloudy House needs a new coat of paint. Each Cloudbaby resolves to paint the door in their favourite colour. None can understand why, when they have painted the door in their favourite colour, it isn't that colour when they return. Of course, another Cloudbaby has already painted over it. When they finally realise what has gone on, they confront Fuffa, who simply says she didn't tell them to paint the door in any particular colour. As they fail to resolve which colour to paint the door, the errant rainclouds rain on the door and make a mess of all the colours. Rainbow suggests to them that they had the solution all along. He is made of many colours and looks fabulous. The Cloudbabies all paint their favourite colour in stripes on the door and soon it is looking wonderful again.

Sun is being put to bed and it's time for Little Star to twinkle. The Cloudbabies have done their chores and go to bed. Little Star hears a rumbly noise in the sky and is spooked by it. He comes to the Cloudy House and taps on the window to wake the Cloudbabies. They allow him to get into bed with them, but his points are too pointy and he has to move from bed to bed until he finally settles with Baba Green. Suddenly they are all woken by the rumbly noise in the sky. They resolve to find out what it is and venture out with nets and a torch. They find it coming from a cloud - it's Sun and he's snoring because he is sleeping on his back. They all move him on his side, the mystery of the rumbling noise is solved and Little Star can twinkle in the night sky again.

The Cloudbabies hear a rumble from the sky and realise that it's coming from Moon, who is in her crescent shape. She's hungry and her tummy is rumbling. She was expecting a moon rock meteor shower for breakfast but it hasn't arrived. The Cloudbabies look for spare moon rock in the Cloudy House but the cupboards are bare. All they have is rainpears. They give the rainpears to Moon but she's still not full. Bobo White alerts everyone to the incoming moon rock shower and the Cloudbabies go to pick up the windfall of moon rock from the skycloud. There is too much moon rock to carry on the skyhorsies, so they call the skytrain. They take the moon rock to Moon, who eats it all. As she eats it, she gets bigger and bigger. Contented, she goes to sleep, radiating moonbeams.

Baba Blue is picking shooting stars from the star tree in readiness for the star slinging later on. Rainbow confirms that he is top condition for it. While Bobo, Skydonk and Fuffa are playing tag, Baba Pink has finished polishing Sun and goes to enlist Rainbow's help to chase some rainclouds away. Baba Yellow also wants to get Rainbow to come to the Cloudy House so she can paint him. Both Baba Pink and Baba Yellow grab Rainbow's hands to pull him in their direction, but Rainbow gets in a knot. He can't sling any stars now. Baba Blue is very concerned and asks Baba Green for help but they can't find a way of replacing Rainbow. Without him, there will be no shooting stars in the sky. Baba Pink and Baba Yellow try a number of ways to untie Rainbow's knot but to no avail. Bobo is still playing tag and as he does so, Skydonk's tail tickles Rainbow. He starts to laugh and in doing so, his knot unravels. Back to top condition, he launches the shooting stars into the night sky.

Bobo White is charging around the skygarden on Skydonk and accidentally crashes into Baba Green's prized fluffigold flowers. The flowers send up a great deal of pollen into the air which forms a yellow cloud. Fuffa is intrigued by this new visitor and tries to make friends with it. However the yellow cloud is unresponsive, and wherever the yellow cloud goes, the Cloudbabies all start to sneeze. No one can work out where these sneezes have come from. Baba Blue, sneezing profusely, visits each Cloudbaby in turn for advice on how to stop these sneezes but with the yellow cloud following closely behind, the sneezing just spreads to everyone. Fuffa is most suspicious but is frowned on by the Cloudbabies when she voices her concerns. They think she is just being mean to the yellow cloud. It is only when Fuffa traces the pollen back to the fluffigold flowers that she is believed. She tries to blow the yellow cloud of pollen away but she is too small to do it.

It is time for Sun to go to bed but Sun does not want to. 'In a minute' he keeps saying. He wants to stay up and play with Bobo White, Little Star and Fuffa Cloud. Bobo is reluctantly dragged off to bed. Meanwhile Baba Green is worried. With Sun up past his bedtime, the sky is too hot and his flowers are wilting. The paintwell is steaming, Rainbow's colours are running and the skyhorsies are overheating. Sun has to go to bed! But he is too over excited. Baba Green manages to peel Fuffa away for a bedtime story. Moon meanwhile cannot come out until Sun goes to bed. Everyone is hot and tired. The Cloudbabies sing the sleepy song while Baba Yellow plays the fluteytoot. Sun slowly starts to fall asleep and is soon snoring. The night sky creeps in and Moon ascends. Everything is as it should be. Even the Cloudbabies are asleep.

The Cloudbabies are having a playtime break from their daily chores and are playing hide and seek. Bobo White is particularly good at hiding. Sun is intrigued by this game and wants to join in. Unconvinced that it will work because he is so big, the Cloudbabies agree. But he is too big and cannot effectively hide behind a small cloud or some horseyhay or the Shooting Star Tree. The Cloudbabies return to their chores but Sun is not to be defeated and resolves to find a bigger place to hide. As the Cloudbabies go about their business, the sky darkens. They wonder why night time has come so soon. No one is really tired yet and there are not enough shooting stars on the tree yet to fling into the sky. Moon arrives sleepy, not really ready for her night time duties. She advises the Cloudbabies that Sun is playing his favourite game and the Cloudbabies have to find him if they want him to come back. The Cloudbabies look everywhere. They cannot find Sun anywhere.

Rainbow is trying to get some rest while Baba Yellow is trying to paint a portrait of the Cloudbabies but Bobo White, Fuffa and Little Star are playing around and getting in the way. The Cloudbabies decide they need a babysitter and ask Rainbow who reluctantly agrees. The Cloudbabies try to find the right place to have their picture painted but nothing is right and they cannot agree on the right place. Bobo, Little Star and Fuffa fool around with Rainbow until his patience snaps and he sends them to the naughty cloud. They call him grumpy which he does not like. Sun tells Rainbow that the sky is too quiet without the noise of the mischievous trio. Rainbow relents and asks them to do one more thing... chase him! Rainbow dashes off through the sky with the three miscreants tearing after him in delight. The Cloudbabies go to see how Rainbow is getting on, still not resolved on where to be painted.

It's morning and Baba Pink has all of her jobs to do. But she didn't sleep well and is still very tired - so tired that she can't stop yawning when she is dusting Moon! Moon suggests she go back to bed and the other Cloudbabies agree to do her jobs for her. She reminds them that they have to give each of their Skyfriends the Baba Pink tickle. Baba Green reads to Little Star, Baba Blue fluffs Fuffa Cloud and Baba Yellow polishes Sun, but they all forget to give their Skyfriends the tickle. Meanwhile, Bobo White and Skydonk are trying to give Baba Pink the rest she needs but they still make a lot of noise. When Baba Pink gets up, now fully rested, Sun, Fuffa and Little Star all arrive to say they didn't get their tickle. The other Cloudbabies apologise and they all make up for it by giving their Skyfriends and each other the Baba Pink tickle.

It is Fuffa's big day. She has a rain test ahead of her. She refuses Baba Pink's help and is determined to practise on her own. Meanwhile Baba Green is planting out a sapling rainpear tree and needs some rain to make it grow. Everywhere Fuffa tries to practice her raining seems to be the wrong place. She rains on Rainbow, she rains on Baba Yellow playing her Fluteytoot and she even rains on Baba Pink's washing. Fed up, she resolves to stop trying and goes off in a huff. Meanwhile there is not a raincloud in the sky to rain on the poor little rainpear tree. The Cloudbabies search the sky for Fuffa but she is nowhere to be found. Until they come to the little rainpear tree where they find Fuffa successfully raining on the rainpear tree and making it grow.

Baba Blue and Rainbow are slinging stars into the sky watched by Bobo White, Fuffa Cloud and Little Star. Bobo and Fuffa think the shooting stars are the best thing in the sky. A little downhearted that his friends did not choose him as the best thing in the sky, Little Star resolves to be a shooting star. But it is time for bed. Baba Pink puts him in his cot but as soon as her back is turned, he is up again. He practises throwing himself off a cloud but it does not work. Baba Pink finds him and puts him back to bed again. Once she has gone, he is up again. This time, he collects all the shooting stars off the star tree but on hearing that Baba Pink's going to check up on him, he abandons the basket of stars in the stables and rushes back to bed. Meanwhile the Cloudbabies find that the star tree is bare.

It is a hot day and there are no clouds in the sky. The paintwell is dry so Baba Yellow can't touch up Rainbow's stripes. Baba Green and Baba Blue go off on their skyhorsies to rustle up some clouds, but Bobo can't help as he is too young. However, they find a cheeky grey cloud by the stables and practise cloud rustling with it. After much effort, Baba Blue and Baba Green find some clouds and bring them back to the paintwell to rain. But the clouds rain everywhere except in the paintwell and soon there is no rain left in them. Rainbow is distraught - now he will never have his colours replenished! Bobo White arrives with his new friend, the little grey cloud, and after some coaxing, the cloud rains into the paintwell and it becomes full again with all of the colours that Rainbow needs for his stripes.

A storm is brewing and it is Fuffa's first. Rainbow is very excited because he likes to conduct the storm. Dark rain clouds appear and Bobo White and Little Star are unnerved by them and the growing noise and retire to the Cloudy House. The Cloudbabies look after them and reassure them that the noise of thunder is natural and it's just the storm clouds' job. Even when the Cloudy House rocks, the Cloudbabies manage to hang onto the pictures and vases and make a game of it. Bobo and Little Star start to feel more reassured. Meanwhile Fuffa is nervously awaiting her part in the storm. Rainbow is conducting the clouds to bang into each other like drums. The rain coming down is like the sound of chimes and the lightening is like the cymbals. The Cloudbabies encourage Bobo and Little Star to come outside to watch Fuffa join in. She does so tentatively at first but soon gets into the swing of it and with Rainbow's gentle encouragement, she is soon thoroughly enjoying herself.

Fuffa is being a little naughty and playing hide and seek by camouflaging herself in the orchard, the smoke from the Cloudyhouse and the horseyhay bales in the Hayfield. Each time, she taunts Bobo and Skydonk that they can't find her, by singing her hide and seek song. The Cloudbabies each hear the song and chide her for giving the impression she is lost. However, when the clouds start coming in, Fuffa really does get lost. She calls for help but the Cloudbabies think she is just fooling around again. Bobo White and Skydonk do find her in amongst the clouds but then they can't find their way out either. When the Cloudbabies hear them crying for help, they rush to the rescue and lead everyone back to the Skycloud. Fuffa resolves never to play tricks again.

The Cloudbabies are giving the stables a makeover. Poor Skydonk wants to sleep in the stables, but he's not allowed. Baba Blue notices his disappointment, and decideds to surprise him and build Skydonk his very own kennel! Bobo is very excited - he spots Skydonk, and quickly takes him to be with Rainbow so that he and Baba Blue can carry on with the surprise. Skydonk is sad that Bobo left him with Rainbow, and despite Rainbow pulling some funny faces, Skydonk is not amused. Soon Baba Blue has finished the kennel, and Baba Yellow knows just the thing to finish it off - a bit of colour! Bobo rushes off to fetch Skydonk from Rainbow, to take him back to see his new home. A very excited Skydonk looks happily at his new home, but when it comes to bed time, he and Bobo are sad not to be staying together. Both Bobo and Skydonk sneak into the night to find each-other. They bump into one another in the kitchen, and hug tightly.

Sun is very confused when everyone says thank you to him for his beautiful colourful sunset the night before, since has never seen a sunset for himself. Meanwhile Baba Green is in the garden. He asks Bobo White and Fuffa if they want to help water the garden, but instead Bobo decides to pretend to be a raincloud like Fuffa, and flies off on Skydonk with Baba Green's watering can. Baba Pink asks Baba Yellow if she is able to help with Sun - she offers to paint him a picture of his sunset so he can see what it looks like. Bobo rushes past with his watering can, spilling the water over the picture - making the colours merge even more like a real sunset. Bobo flies off, and Sun turns to the Cloudbabies looking really sad. The Cloudbabies try putting him to bed, but soon realise he can't see the sunset if he is asleep, but he can't make the sunset if he is awake! Bobo White runs out of water, and accidentally fills his watering can with blue paint.

Bobo and Fuffa are playing at being a skytrain, with Fuffa as the train and Bobo as the driver. They tear around the Skyworld causing trouble until Baba Yellow tells Bobo that if he calms down and is good, she will take him on a ride on the real skytrain later. Bobo and Skydonk go off to find something to do. Each time Bobo is tempted to be naughty, he dutifully doesn't and returns each time to Cloudyhouse to ask if it's time to ride the skytrain yet. Baba Yellow eventually tells him to wait by the skytrain bell until she is ready, but not to ring the bell. This proves to be a temptation too far. Bobo rings the bell and summons the skytrain. He jumps in with much delight and as it picks up speed, he is joined by Fuffa and Little Star. But the train goes faster and faster and Bobo can't control it. The Cloudbabies are alerted to their predicament and corrall a bank of clouds as a buffer to slow the train down, but to no avail.

The Cloudbabies are vying for the very last, biggest, juiciest rainpear from the orchard. But who is going to eat it? Sun suggests a race - around himself, of course. Bobo White wants to join in and although initially reluctant to let him because he's too small, the Cloudbabies relent and let him and Skydonk enter the race. Bobo and Skydonk don't make a very good start. They trample the garden and Baba Green has to return to tidy up. Bobo is still behind, until Rainbow bounces him back into the race. But in doing so, he smudges his colours and Baba Yellow has to turn back to repaint him. Baba Pink and Baba Blue are out in front until Bobo bumps into Moon, disturbing her moondust. She blows the dust away and in doing so, propels Bobo within touching distance of the other two Cloudbabies. But Baba Pink now has to go back to Moon to dust her. Baba Blue and Bobo are going round Sun when Sun gives them a hand by spinning them around.

It's a clear, starry night and the Cloudbabies are collecting Moon's moonbeams and winding them up like balls of wool. They return to the Cloudyhouse passing Sun who is snoring and sounds like he has a blocked up nose. When they wake the next morning, something is wrong. It is still dark. Baba Pink goes to see Sun to find out that he has a cold and this prevents him from shining as he should. Moon agrees to stay out a bit later to cast her light over the sky but she can't do this for long. The Cloudbabies try to make Sun feel better by bringing him rainpear juice, making him a get-warm card and bringing him flowers but nothing seems to be working. Meanwhile, Bobo White and Skydonk have found the balls of wound up moonbeams and are playing with them. As they are doing so, they unravel the moonbeams and get them into a big mess with Skydonk wrapped up in it all. He complains that he is hot. Baba Blue hears this and has an idea how to make Sun better.

Baba Yellow is rushing about the Cloudyhouse looking for her bag. The other Cloudbabies leave the house to begin their day's work. Soon Baba Yellow finds her bag but is in such a hurry, she leaves her Fluteytoot behind on the table. Without it, she is unable to play Little Star his lullaby so she rushes back to the Cloudyhouse to find it. Bobo is bored, and spots the Fluteytoot on the table. Knowing Baba Yellow will need it, Bobo picks up the Fluteytoot and rides off on Skydonk to find her. Baba Yellow comes rushing into the Cloudyhouse a moment later only to find the Fluteytoot has gone! Bobo heads to Little Star, and decides that he should play a lullaby for Little Star but Bobo's playing is so bad, Little Star hides under his blanket. Baba Yellow races back to Little Star. Not knowing that he is under the blanket, Baba Yellow is sure he must have gone and panics that she must have lost him too. Baba Pink offers to help and with the other Cloudbabies tries to find Little Star.
