Meet Sarah, seven years old, with big eyes and a green hat who lives with her quacky, flappy best friend, Duck. Sarah and Duck live in a small village, in a small house, with a small, wonky garden path and a red front door. Together they embark on simple but exciting adventures, exploring their world both near and far in their own wobbly and imaginative way, joined by friends and neighbours including Small Scared Bug and Scarf Lady.
