Write a really funny Thomas transcript based on my prompts:

One day in the sheds, Percy is eager to tell a disinterested Gordon and James some news. He tells them that because the work in the yard is getting too hard for him, the Fat Controller is planning to bring a new bigger engine in to help. James scoffs and tells Percy that if he spent more time working and less time talking, the yard would be a happier place. Percy, unfazed, leaves to do his work.

As he works, Percy is grumbling to himself about how the larger engines see him as a “silly little engine” ever since he accidentally reversed at a signal and often order him about. Percy wants to teach them a lesson but does not know how to do it. He works very hard all day and by the afternoon he is worn out. After bringing some express coaches to the station, he sees the Fat Controller on the platform who notes that Percy looks very tired, which Percy confirms. The Fat Controller consoles Percy by telling him the new engine is bigger than him and can probably manage the work alone. He then asks Percy if he would like to help Thomas and Toby build his new harbour, to which Percy happily agrees.

The next morning, the new engine arrives. The Fat Controller asks the engine his name and the engine introduces himself as Montague but tells the Fat Controller he is often called “Duck” due to his supposed “waddle”. Although he does not believe that he does, he admits to liking Duck better than Montague. With that, the Fat Controller agrees that the new engine will be known as Duck. Percy arrives and the Fat Controller asks Percy to show Duck around.

Duck does his work quietly as he brings some coaches to the station, leading Gordon, James and Henry to decide to order him about like they do to Percy. Gordon and Henry then start to leave the station on either side of Duck, quacking and blowing steam at him. As Percy sees everything and is cross, Duck takes no notice and just wants to wait until the larger engines get tired. Duck then asks Percy if the larger engines boss him about and Percy confirms they do. Duck decides to take charge and put a stop to it and tells Percy what they will do.

That afternoon, the Fat Controller is sitting at his desk looking forward to having toast for tea when he suddenly hears a horrible commotion coming from the yard. Looking out his window, he sees Percy blocking the turntable and preventing an enraged Gordon, James and Henry from entering the sheds. The Fat Controller grabs his hat and rushes to the yard.

At the sheds, Gordon, James and Henry are furiously wheeshing and whistling loudly when the Fat Controller arrives and orders them to stop the noise before demanding Duck to explain his and Percy’s behaviour. Duck politely explains to the Fat Controller that, as a Great Western engine, he prefers to do his work without any fuss but wants the other engines to know that he and Percy will only take orders from the Fat Controller himself. As the three larger engines start whistling angrily again, the Fat Controller silences them. He then tells Duck and Percy that he is pleased with their work that day but not with their behaviour that night, as they have caused a disturbance. Gordon, Henry and James snicker at Percy and Duck’s dilemma, but the Fat Controller turns back to face them and reprimands them too, as their actions have been much worse, they made the disturbance by ordering the two tank engines around. He says that Duck is right; this is his railway and he is the one to give the orders, not them. With that, the three engines quickly fall back into line.

When Percy is sent to work at the new harbour, Duck is left to do the work by himself, which he manages to do with ease.
