During their time aboard the Molentary Express, Professor Layton and Luke solve quite the number of puzzles. One of these puzzles is given by Sally in car six. The only puzzle she gives them is "Pancake Stacks 1".
Sally has dreams of big-city life, but for now, she just pushes the cart in the Molentary Express, offering a bevy of appetising snacks to disinterested train patrons. She can often be found trading quips with her buddy Hank.
