Gordon goes in search of Big Boot, the legendary Gnome that roams the woods behind his garden. Percy guides the expedition with the help of a "Nose on a stick" but ends up getting them all lost. And Gordon’s attempts to get a picture of Big Boot are thwarted by the Chief Gnome and Gladioli, who keep frightening him off. Rosie manages to lead them all home with her natural tracking ways – where it seems that Jerome has spent all afternoon in the company of Big Boot!
