Fort Sponge

Fort Sponge is a Sponge stronghold on the edge of the Funny Sea. It is bordered by the town of Sponge-Upon-Sea, though dwarfing it with its sheer size. It is the main Sponge deployment base for battles in distant lands, most notably against the Doges in Dogeland and the Robot Communists in Russia. It also has put down revolts in the Sponge Islands, though it's only really used in extremely serious situations.
