"The rousing notes of the bugle and the laughter and shouting increased the feeling of rebellion within Ralph. As the last strains of the bugle call hovered in the clear mountain air, Ralph made up his mind. He knew now what he was going to do. He was going to run away. Fed up with his timid mother and uncle and his squirmy little cousins, Ralph hops onto his toy motorcycle and zooms down the road to summer camp. It turns out camp is not all peanut butter and jelly sandwiches and fun. A strict watchdog, a mouse-hungry cat, and a troubled boy named Garf lead Ralph on some fur-raising escapades. Perhaps home isn't such a bad place to be, if only Ralph can find a way to get there again.

Presents the further adventures of a motorcycle-riding mouse who goes to school and becomes the instigator of an investigation of rodents and the peacemaker for two lonely boys.
