The market is more crowded that anywhere Arthur's been in his life, having grown up underground.
Watching some kids play, Arthur asks Willbury what normal children do. Willbury says they go to school and play with friends.
Arthur gets all bummed and says he doesn't think he has any friends. Willbury stops that pity party and tells Arthur that they're friends, along with the boxtrolls and cabbageheads.
As they get closer to the market, they see some fashionable ladies cackling as they totter around on heels. Their dresses are padded in the back and come in interesting shapes like cones and pyramids.
Willbury guides them into the market, which is kind of overwhelming for Arthur. Finally they arrive at a pie stall.
The pie-maker, Mr. Whitworth, wraps up pies for Willbury and Arthur; then Willbury says he's trying to get in touch with Marjorie and asks where she is.
Mr. Whitworth fills Willbury in: She's been camping at the Patent Hall since they lost her applications weeks ago. If she leaves the line, she could lose the right to her invention.
Willbury decides to pick up more pies so that he can deliver some to Marjorie, and Mr. Whitworth gives them everything for free, since he's all about supporting Marjorie. He throws in a cake, too, which is exciting for Arthur since he's only ever heard of cake.
Arthur takes the sack of pies for Marjorie, and then he and Willbury set off again.
