“Workmen, fit the whistle! The whistle is clearly wonky!”

Wonky Whistle is the seventeenth episode of the fifteenth series.


It is the day of the country show on Sodor and Thomas is at the Steamworks having his whistle replaced. Then the Fat Controller arrives to tell Thomas that he is to pick up Farmer McColl's animals and take them to the country show. He also tells Thomas to whistle to everyone and tell them about the show. Thomas is excited and tells Kevin to hurry up, but Victor warns Thomas that he must wait for his whistle to be fixed and instructs the workmen to fix it. Just as the workmen are about to straighten Thomas' whistle, he speeds off, and as he leaves, Thomas blows his whistle, which makes a horrible noise. The noise startles Kevin, who rolls into a wall.

At Farmer McColl's farm, Thomas collects Farmer McColl's ducks, Katie the sheepdog, and his prize cow. However, Thomas eagerly races off before the van's door is properly shut. Thomas decides to puff to the bridge; he is sure there will be a lot of people there that he can inform about the country show. Once there, Thomas tells them to visit the country show and blows his wonky whistle. The noise scares Katie, who leaps from the van and runs off. The people on the bridge call after Thomas, but he thinks they are waving hello. Thomas decides to visit Maithwaite station, and on the way, he sees Bertie at a crossing. Thomas is sure his passengers will want to know about the show. He tells them all and then whistles, scaring the ducks out of the van. Bertie calls after Thomas, but Thomas thinks Bertie is tooting hello and carries on to Maithwaite station, where he blows his whistle once again. This time it frightens the prize cow, who runs out of the van and across the platform. The stationmaster shouts after Thomas, but once again, Thomas thinks he is calling hello.

Soon Thomas arrives at the country show. Thomas is surprised to see that there is no one at the show. But not as surprised as Farmer McColl when he opens Thomas' van. Thomas is upset, he was told to tell everyone about the show and to deliver the animals but has done neither properly. Thomas blows his wonky whistle and scares some sheep, who run out of their pen. Farmer McColl waves and shouts at Thomas as he runs after the runaway sheep. Thomas concludes that his wonky whistle has scared the sheep and must have scared the other animals away too.

Thomas races to the Steamworks to have his whistle straightened, and then goes to Farmer McColl's farm to collect the animals' favourite foods. Thomas then collects Katie the sheepdog, the ducks, and the prize cow. Eventually, Thomas arrives back at the country show where Katy rounds up the runaway sheep. Then Thomas goes around the Island telling everyone about the country show again. Back at the showground, the country show is crowded with people. The Fat Controller is delighted and gives Thomas one last job: to declare the show open by blowing his whistle, to which everyone celebrates and cheers.
