The next day, Caractacus goes to Lord Scrumptious's candy factory to sell the design and raise the money needed for the Panther. Caractacus's father, Grampa Potts, recounts the family's troubles (' Them Three') and after trying some of his son's inventions, realizes he has devised a candy that can be played like a flute. Truly arrives at the Potts household, an old windmill, with the children and lectures Caractacus on their improper upbringing before leaving as he prepares a meal for the children (' You Two'), they tell him about the plans to scrap the Panther and he promises to purchase the car for them. Meanwhile, Vulgarian spies acting under the direction of their leader, autocratic Baron Bomburst, have discovered the location of the Panther and make plans to purchase the car before the children. Truly Scrumptious, daughter of the wealthy Lord Scrumptious, arrives at the junkyard seeking a spare part, but upon finding the truant children, takes them home to their father, the widowed inventor Caractacus. They are shocked when the Junkman tells them he plans to scrap it, but he promises to save the Panther for them if they can purchase and move it within a few weeks. Years later, the Panther sits in a junkyard, forgotten by all save the young siblings Jeremy and Jemima Potts, who are enamored with the Junkman's tales and the car's history. The Junkman/Coggins recounts the last race of the Paragon Panther ('Opening'), which was contested against the Vulgarian Vulture in the 1910 British Grand Prix, but the Panther crashed after Vulgarian spies sabotaged it.
