Buddy is a normal 7-year-old growing up in a normal family in a normal town. His best friend is a cocker spaniel named Billy, who is not so normal: He can make himself understood by humans without words and can talk to other animals. Billy's best friend is the family's tortoise, Caroline. Together, Billy and Buddy get up to all sorts of mischief, gently tormenting those around them. The family setting is overflowing with love and tenderness, and the duo's pranks are guaranteed to make readers of all ages roar with laughter.
Jean Roba started illustrating for Spirou magazine in 1957, after a stint as an illustrator in advertising. He created the first Boule et Bill adventure in 1959, with a script by Maurice Rosy. After a complete trial story, Boule et Bill became fully established as a weekly cartoon strip, and Roba kept this pattern for almost 20 years, giving the characters only one book-length adventure in 1982.
