This non-speaking naval tramp steamer made her first appearance in "Ghosts" and her final appearance in "Munitions". Due to a fuel drum falling onto some explosives after Bluenose hit Zorran's barge, the dock caught fire; thus setting off the explosives and fuel loaded in her at the time. Since she was nearly full, the contents did indeed "rip her apart" as Zorran predicted, and she sank into the bay, but continued to appear in the background hinting she was recovered. She never spoke. She was named after the Krakatoa volcano, which famously erupted in 1883, causing much devastation.
