Jigger was a male shrew member of the Guoraf. He was the son of Log-a-Log Briggy, and bore a startling resemblance to his father. He worked together with Bragoon and Sarobando to fight off a band of reptiles, and took a fancy to Springald, one of the young female companions. Following their adventures, Jigger met Lonna Bowstripe when he came to Redwall Abbey to announce the return of the travelers.
Jigger was a friend of Wuddle, and played the shrewlodeon.
