At the beginning of the episode, Mr. Conductor tells his dog Missy that he is tired of the red color of the door on his signal box, so he decides to paint it a different color. He decides red with green stripes, as it reminded him of what happened to Henry in "Come Out, Henry!"
After the story is done, Mr. Conductor has painted the door green, but he is not pleased with it, because that particular green is the same color of fish, and it reminds him of Duck's incident in the story, "Fish."
Mr. Conductor switches it to blue, but finds that it is not the right color either because it would give people the blues, so he decides to add another color that is appetizing: Orange. He then tells the story of Gordon the Big Blue Express Engine in "Whistles & Sneezes."
After the story, Mr. Conductor has added orange stripes to his blue door, which has the style of a circus tent. Mr. Conductor realizes that this type of color would attract elephants, which can be troublesome, as he explains in the story, "Henry & the Elephant."
Mr. Conductor switches it to blue with yellow polka-dots, but still doesn't look right. He soon realizes that the door-painting idea was not a good one after all, and he remembers the effects of a new painting job that had on Percy in the story, "Bulldog."
In the end, Mr. Conductor has repainted the door back to its original red color, which he finds perfect for it, as it reminds him of home. However, he cannot touch the door to go inside, as the paint is still wet, so for now, he uses his gold dust instead. The episode ends with Mr. Conductor and Missy listening to the song, "Let's Have a Race" on the radio.
