When Koko sees the pretty design that Lori has painted on Zephie's face, she decides she wants one too and the two of them compete to see who can get the biggest and best design. Lori's too busy repainting rolling stock in the automated spray shed to help, so Koko and Zephie decide to paint each other using the paint car.

Koko paints Zephie with spiders and Zephie gives Koko a beard and moustache! They laugh when they realise they've played a trick on each other - but the laughing stops when they discover the paint is permanent! They rush to the spray shed and help each return to their original colours and decide they don't need a new look after all. They're fine just as they are!

Frostini, une loco qui vend des crèmes glacées demande à Bruno, Coco et Wilson de l'aider à en vendre.

Calley is teaching Hoot and Toot how to use the sliding turntable. When she gets called away on an emergency, she asks Brewster to take over the training. The twins find Brewster's methodical way of teaching a bit boring and make their escape. Brewster chases them all over the depot. The twins accidentally get on the track lift, which sends them straight underground. They explore for a bit, but when they want to get back they can't - not without using a turntable!

They wish they'd listened more to Brewster... but his method must have worked, because gradually they remember what he said. Brewster comes looking for them underground just in time to see them operating the turntable perfectly and when Calley sees them demonstrate the turntable later, she thinks Brewster is a fantastic trainer. Hoot and Toot agree!

It's a cold, snowy day in Chuggington and every available chugger is heading out to plough, except for Chatsworth, who is going for a rest after ploughing all night, and Hoot and Toot, who are too inexperienced to be out in the snow. Koko and Harrison head off as a team, Harrison boasting there isn't a drift that can stop him! He blasts through drift after drift and when they come across the biggest drift of all, Harrison tackles it head on and gets stuck inside it!

Koko assembles an enormous conga line of chuggers to get him out but they can't quite manage it until, at the last minute, Hoot and Toot and Chatsworth come to the rescue, coupling onto the back of the line, giving the extra strength needed to pull an embarrassed Harrison free.

Eddie and Hodge have cleaned the sludge out of the chugwash. Now they're going to refill the chugwash soap, then clean the underground tunnels using the Scrub-A-Chug - a fantastic piece of rolling stock with brushes that cleans the ceiling of the tunnel. Their work is interrupted when they get called away on an emergency. Wilson decides to be helpful by finishing their chores.

Unfortunately, he accidentally replaces the chugwash soap with chugwash sludge and when he tries to clean the tunnels with the Scrub-A-Chug, he ends up making an even bigger mess! Happily he figures out a way to use the chugwash soap with the Scrub-A-Chug and when Eddie sees the sparkling clean tunnel, he's thrilled. How clever of Wilson to discover that chugwash soap actually helps the Scrub-A-Chug to clean even better!

Dr. Ling is giving a talk about meteors and how, many years ago, one crashed right near this area. Brewster pulls in a real meteorite, borrowed from the museum. Dr. Ling demonstrates that you can move the meteorite with a magnet, as meteorites contain metal. Hoot and Toot are afraid the meteorite might escape and destroy Chuggington, so they decide to return it to space. They take it up the mountains and try to catapult it into the sky, but it falls to earth and races toward the city! Hoot and Toot chase it as it rolls around Chuggington. With the trainees' help, they capture it, using the magnetic crane. They tell Dr. Ling they were only trying to return it to its home - but she says its home is the Chuggington Museum. Hoot and Toot are glad they don't have to say goodbye to the meteorite. They've grown quite fond of it!

Brewster is going to be carrying Mayor Pullman, the new Mayoress of Chuggington, across the newly re-opened Border Bridge in the traditional welcoming ceremony. During the practise run, some of the facade falls off one of the bridge's pillars. It looks as though the ceremony will have to be cancelled, as the bridge might not be safe! At first Brewster is devastated - but then he saves the day by using something Dr. Ling's been working on: her new soap was a disaster in the chugwash, as it set into rock hard foam, but it's perfect for repairing the bridge! Safety restored, Brewster proudly carries Mayor Pullman into Chuggington.

The new Mayoress, accompanied by her nephew Denzil, is touring Chuggington. She's observing the chuggers working, in order to help her decide who should be the recipient of the prestigious Chugger of the Year award. Koko is sure she's in with a chance - but rather than doing her jobs, she spends her time trying to impress the Mayoress. In the process, she ends up nearly ruining the ceremony. Speedy comes to her rescue time after time.

In the end, Koko realises that she hasn't kept her mind on the job and she doesn't really deserve such an honour - but she's thrilled when the Mayoress, with a little help from Denzil, decides that Speedy is this year's winner!

The defect detector is a device that lets Vee know if there's anything wrong with chuggers as they pass by its scanners. Unfortunately, it seems to be malfunctioning! Eddie takes it off to the repair shed and Emery, wanting to be helpful, takes its place. But, worried that he might miss something, Emery sends nearly everyone to the repair shed, creating chaos in the depot! Emery feels bad that he's caused so much work for Vee and wishes he could make up for it. He has an idea. If the detector could talk, it wouldn't have to do everything through Vee. Dr Ling and Eddie think it's a great idea and they update the detector so that it speaks. And they know the perfect voice to use Emery's!

Eddie is having a very busy day and Hodge really wants to help - but all the jobs need hands not wheels. When Wilson reports the track lift is malfunctioning, Hodge decides to try to fix it himself. He only makes matters worse, bringing the lift to a grinding halt with Wilson stuck on it! Eddie agrees to let Hodge go and fetch the lift part needed, as long as he uses Dr Ling's Chugnav to guide him on his journey. Unfortunately, Action Chugger has knocked the satellite, which has skewed the signal, leaving the Chugnav talking utter nonsense! Hodge figures out that the satellite must be broken - so Action Chugger takes Hodge on an exciting trip into space to fix it. Hodge finally gets to help out!

Koko decides to try for the High Speed badge - something no trainee has ever won. Emery wishes he still earned badges like the trainees do. For fun, he plays a 'pretend badge' game with Hoot and Toot, where they award each other imaginary badges. Emery is so busy playing his game that he doesn't listen when Vee assigns him to take some supporters to the footbridge to cheer Koko on. Realising that he was so wrapped up in his pretend badge game, he forgot how important the real badge was for Koko, he takes it upon himself to be her number one cheerleader. Koko is flagging, but with Emery's encouragement, she bursts through the finish line! Emery learns that he doesn't need badges anymore - it's enough to know he's done a good job.

Toot doesn't want to do track inspection with Hoot. To get out of it, she pretends she isn't feeling well. At first she enjoys getting lots of attention, but when Morgan thinks her flywheel needs replacing, which means having her engine taken out and spending the night in the repair shed, Toot realises she's gone too far. She confesses that there's nothing wrong with her - she just didn't want to do the track inspection!

Toot realises she has caused a lot of trouble for everyone and promises never to do it again. She and Hoot head off to do the track inspection. Actually, It turns out to be really fun and Toot realises she was making a fuss over nothing.
