Broom, vroom, beep! Maisy and Charley are in the city visiting their friend Dotty, and there are many things to get used to - noisy traffic, enormous buildings, and sidewalks so crowded they have to walk very slowly (all the better for looking in store windows). Riding the escalator and elevator - and hanging on tight in the subway - are almost as much fun as exploring the giant toy store and eating pizza in a cafe. Even the playground is busy in the city!
