Toolam was a male water rat in the Marlfoxes' army. He and a dozen others traveled south with Mokkan when the Marlfox escaped his siblings. Toolam was promoted to Captain of the Army, replacing Ullig. He was a bit of a dullard, but found his brief rise to power to be intoxicating and abused it while he had the chance. Shortly after his promotion, Toolam tried to lead a guard force out of the castle when the slaves rebelled. However, Song and Burble were hiding in an alcove, and ambushed them, pushing the unlucky rats down the stairs. It is not mentioned whether or not Toolam survived the fall.
