Log-a-Log of the Guosim led the tribe at a time when Captain Snow and Asmodeus terrorized them, and when the Guosim used the Blackstone. He was a descendant from a long line of ferry shrews. Log-a-Log directed Matthias to the residence of Squire Julian Gingivere, and with the president Guosim, accompanied the warrior mouse to the quarry where he retrieved the sword of Martin the Warrior from Asmodeus. Log-a-Log then assisted in the battle for Redwall Abbey against Cluny the Scourge. Flugg was named as his successor.
