Sporty has invented 'botball' which entails kicking a tin can as hard as he can and shouting 'goal!' Stripy doesn't notice the tin can landing on Teddy and panics, thinking his little friend has gone missing. The Little Robots search everywhere but in the end it's Messy who finds him - squashed inside the can.
Spotty is having one of her routine inspection days when Rusty reports a strange encounter at the Oasis. It takes Spotty no time at all to deduce that an intruder has broken into the Little Robot world and they are about to be invaded. She quickly mobilises a Little Robot task force to deal with the crisis only to get captured herself. Soon, however, she discovers what we knew all along - the so-called invader is really Stretchy's latest invention, a remotely-controlled Collectabot.
Tiny oversleeps and doesn't turn the day on until way past time, so Stretchy decides to make a waker-upper machine, with a little help from Noisy. It performs admirably but Stretchy has forgotten to include a switcher-offer switch. They take it to the Wasteland where, it is hoped, it will run down. But Noisy has other ideas and with Tiny's help, turns it into a musical instrument.
Scary has a problem. His ghost train is not working and he had planned to invite everyone to a ghost train party! Sporty, meanwhile, has decided to see just how fast he can run. Unfortunately for him he gets stuck in go mode and speeds through the Little Robot world causing havoc. Tiny ingeniously manages to solve both problems with the help of Sporty's treadmill.
The Sparky Twins ask Scary if they can borrow Flappy to be in their new show. Scary's not keen but agrees, only to change his mind as soon as they have taken her. The Sparkies, practising their juggling, accidentally bop Flappy on the head and she flies off erratically into the night! They panic, but with the help of Messy and a trail of bat shapes across the Little Robot world, Flappy is eventually found.
Scary wishes the bunting he's put up would flutter, so Tiny offers to build him a wind machine. Scary can't keep his fingers off the buttons and the wind machine goes berserk, blowing him into the Nut and Bolt tree. Tiny has to work out how to stop the wind machine, and he literally rises to the occasion and proves himself a hero.
Stripy steps on the Sparkies' rollaplank and crashes into Noisy's house, damaging it badly. Tiny offers to repair it and Stripy suggests that Noisy stays with him in the meantime. But the arrangement is not ideal - Noisy is very noisy and Stripy doesn't like having his peace and quiet disturbed. The Sparkies and Tiny each come up with a solution - but their solutions lead to more trouble!
The Little Robots are doing their Busy Bot jobs and Sporty finishes first. The others ask him to help them finish their jobs but soon it is all out of control because he cannot keep up. Tiny cannot believe they have left Sporty to do everything while they play Botball and when they find him, he is malfunctioning. Tiny repairs him but he does not want to rest so Tiny suggests that the Little Robots do Sporty's exercises while he calls out the instructions!
It is almost Metal Makes Us Special Day, a happy day when the Little Robots celebrate what they are made of! Tiny tells them to start the procession of floats in the Oasis and head back to the Nut and Bolt Tree but it all becomes chaotically competitive. They finally agree it has been a huge success when they sing their song: Metal Makes Us Special!
Spotty has decided that the Little Robot world is a bit lax in safety terms and starts checking everything to ensure that standards are lifted. Scary will have to issue safety warnings at the Ghost Train, Stretchy is not to pile his junk so high and Tiny is just not safe up the Nut and Bolt Tree without his harness. Spotty climbs high to survey the Little Robot world - only to find out that she is afraid of heights and Tiny has to talk her down.
The Sparkies, Spotty and Scary all need help from Tiny. He sorts out their problems - but not one of them remembers to say thank you. Tiny decides he is going to snooze and let them get on with it. Then Spotty gets the Clean Machine stuck in reverse and causes chaos, but Tiny tells her he is too busy to help. But he does help Flappy and she thanks him loudly. Scary works out that Tiny doesn't mind doing anything for any of them, but he does like a thank you!
Rusty is expecting Sporty, but it's Spotty who turns up. Unfortunately she has a tumble on the stairs, loosens a screw and gets stuck in demolition ball mode. She wrecks Rusty's home and ends up wedged against the door, trapping her. Stretchy comes to the rescue, lifting Tiny up to the opening in the roof, and soon Spotty's screw is back where it should be and all's well.
The Sparkies find a box of bits that they turn into vehicles with joysticks. They discover if they twiddle them, they can make the Robobirds spin round on their perches, Stripy whirls and Sporty jumps up and down when he doesn't want to! Tiny investigates and decides that he's got to stop them before it all gets out of hand. With a quick tweak of the joystick when they're not looking, Tiny has the Sparkies cartwheeling out of control and landing in a heap beside the Nut and Bolt Tree!
Tiny's new invention causes much excitement amongst the Little Robots.
Messy, playing fetch with Tiny, returns with Stripy's teddy instead of the stick. He runs off with the little bear and Tiny chases them, but Messy and Teddy become separated and Teddy begins a series of adventures as he is accidentally passed from one robot to another. He appears in Scary's magic show, plays in Noisy's orchestra and flies with the robobirds. Tiny doesn't want to worry Stripy by telling him his bear has gone missing and is always just one step behind. In the end Teddy ends up back where he started, with Stripy completely unaware he was ever missing.
Spotty persuades Rusty to head off into the Wasteland with her to sleep out under the stars. Eventually they manage to set up camp and start to enjoy themselves but their stargazing is interrupted by weird lights, shadows and strange noises. The Sparkies have heard about the expedition and have decided to liven things up!
Scary decides he wants to be more like Flappy the Bat and maybe even fly to the moon. He practises hard but when he tries hanging upside down, he falls on his head. He's so ashamed that when Tiny and the others turn up he tells them to go away. What they don't know is that he's busy building a slingshot with the help of a rubber band. In the end he fires himself up to the sky, impressively silhouetted against the moon. He may look like a bat - but he needs Flappy's help to get down!
The Sparky Twins are up to their usual tricks, causing mayhem and chaos.
Scary wants to put on a show and goes on a search for a glamorous assistant.
Tiny's metal measurer is used as a seesaw by the Sparky twins, who soon discover, when they offer Spotty a seat, that it is easy to send her flying straight up into the air!
Messy hits his head and all of a sudden starts to moo, baa and miaow instead of barking. Meanwhile, Noisy challenges Scary to come up with a noise she doesn't know though she warns him she knows every noise there is.
Rusty's collection of small metal things keeps disappearing, one by one. She can't work out what is going on and asks Tiny to help. In the end they discover that the Robobirds have been removing things and hiding them at Scary's, jamming his lift. Rusty decides it's easier to let the Robobirds have her first collection and start another one!
Scary wants the other Little Robots to make things fun for him for a change but gets frustrated when they build a fence round what they're building so he can't see. He tries various different ways of looking in but gets caught out every time. In the end when he finds out what the surprise is, he's so thrilled he doesn't mind any more.
With Stretchy's help, Scary builds a maze in the wasteland. Everyone is excited about the new attraction until Tiny gets lost in it. Various ingenious attempts to rescue him are thwarted by Messy who has his own pressing agenda. First Rusty and then Scary himself find themselves lost in the maze too. Only a worried Noisy is left outside. But when Tiny looks up from inside the maze and sees the robobirds flying overhead he gets an idea. He tells Noisy to go and find Stretchy and soon the tallest Little Robot is busy guiding his friends to safety!
Stripy knows he's holding Tiny and the others up when they are busy building, so he decides to adjust his circuits to make himself go faster. The others are very surprised when he strides past, very fast - and then again and again. Tiny realises Stripy has managed to put himself into repeater mode and confusion mounts. Tiny engineers a solution and the Little Robots are happy to have the Stripy they know and love restored to them.
It's Sparkle Day - a special event - and Tiny leaves the daylight on for extra time for the celebrations. The Little Robots choose who gets to wear the sparkly crown and be made a fuss of. Everyone loves Sparkle Day except Rusty, who is too shy to sparkle. Tiny finds a way to turn her into the sparkliest Little Robot of all.
