Ringmaster Tony sets off on a journey, leaving his circus in the care of Dolores and Toby. Enjoying the new challenge, Toby puts his all into learning the ropes and proves to everyone that he can be a great ringmaster.
A sell-out show demands something special, Momo explains to Toby. He suggests that he use any spare time he has to practise doing something extra for the audience. After trying to find out what he is good at, Toby discovers an old magic trick box in his caravan and opts to perform a rabbit-and-hat trick.
After asking the performers to come up with some spectacular new acts to go into the show that night, Toby ends up being peacemaker when Li and Ling squabble. Then Thor comes up with a great idea for a karate book-chopping trick, but picks the book that Dolores is reading for his act. Luckily, she has a sense of humour!
Freddo is not allowed to appear in the show because he cannot sing, but Clara and Toby realise that it is because he is unable to count.
Toby is proud of his new hat, which has just arrived from the cleaners. Dolores advises him to keep it safe on the costume rail, but it doesn't even get there. Along the way the hat survives various close encounters with Thor, Clara and Freddo but it is eventually flattened by Ling. Oh dear! Toby can't do the show without his new hat!
Acrobat Ling has an accident that means she cannot perform, so Toby turns to his ex-trapeze artist mother for help.
Dolores asks Freddo and Clara to speak to Toby when she receives news that the circus vehicles are to have their wheels inspected. Unfortunately, mimes and funny actions aren’t the best ways of communicating this particular piece of important information.
Dolores asks Thor to perform in the show finale, but dancing does not come naturally to him and he struggles to practise his routine.
Dolores washes the costumes, and Momo and Toby hang them on the line to dry. However, when they return they find Toby's costume and Dolores's bloomers have vanished. A search ensues - will the costumes be discovered before show time?
Somebody keeps stealing Dolores's banoffee pies, but the culprit is discovered when the treats are found in Toby's magic cabinet. Who was the sweet-toothed thief?
Clara misplaces her juggling balls and all the friends offer her other objects to use for the evening's performance, while Toby tries to find out which cheeky monkey has borrowed Clara’s balls to play with.
When Li and Ling work a diabolo into their act, Momo is fascinated and can't resist trying it for himself. When no one is looking, he throws the spinning top work high into the air and waits for it to come down. But the diabolo has vanished. Will the girls discover where it has landed?
Toby decides that tonight's show will be a silent circus to give Dolores time to recover from circus flu. But rehearsing in silence isn't easy, especially for Clara. There are many noisy mishaps but none wake Dolores, until just before the show.
With the circus performers looking forward to Christmas, Dolly and her husband Dennis come to visit Dolores, who agrees to look after their baby Diddlums while they go shopping. Diddums however is only happy in the arms of the robot strongman Thor.
Jango the one-man band finds he is playing too many instruments, so Toby offers to take charge of his tin whistle. But the noises he produces make Dolores think her cold kettle is boiling and Freddo think either his boots are squeaking or the carousel needs oiling.
Thor is dismayed when he accidentally breaks Ling's favourite vase and Freddo's plate. It's been one of those days so he hides himself away to keep out of any more trouble.
After seeing how hard Freddo concentrates while he is balancing custard pies on his fingers, Toby comes up with a splendid idea of how Freddo can conquer his fear of heights.
When some new mats arrive for the helter skelter, Toby is more interested in trying them out than getting ready for the night's performance.
Li ignores the correct instructions for operating a German wheel, and Freddo does not pay attention while he and Clara are practising a new comic routine on a barrel.
Auditions are held to find a replacement when Jango loses his voice, but Delores is too loud, Clara cannot remember the words and the twins squabble about who should sing which parts. All seems lost, until they decide to form a girl band.
Li and Ling fall out over their high-wire act. Thor brings in a new balancing pole to help cheer them up.
The circus moves camp, but Clara is left behind. When Tony realises that she is missing, he sets off with Freddo, Bish Bash and Bosh to find her.
Ling gets tied in knots on the trapeze platform, but Toby comes to the rescue. Unfortunately, he does not like heights and freezes halfway up the ladder. Now Toby needs rescuing as well! Luckily, Jango knows just what to do.
Someone steped in wet paint and ruined the new poster by walking over it, meaning the search is on for the culprit. Everyone's feet are checked, but it becomes clear the mark was made by a stilt.
Toby sets up a human cannonball for a brand new big finale. Li volunteers to be the one shot out of it, but she has second thoughts when it comes to the night.
When Thor cannot find his hammer, he discovers the dodgems are using it to make a beat for their new routine, so he finds them a replacement - but this happens to be Delores's secret ingredient for her special cake.
