Changes

When Tin agrees to look after Nickel for the afternoon, you can tell he really just wants her to play peacefully while he reads his comic. But little sisters have a habit of not doing what you want, and before he knows it, Tin is up off his sun lounger and racing after Nickel to keep her from danger. As he and Zinc the dog chase after her, they find themselves in an adventure of their own in the big city.
