Old Rusty is a rusty old naval tramp steamer. He makes only a brief appearance in Warrior, anchored out in the estuary, claiming to have been anchored there for two years. He seems to be kind and joked with Warrior saying it would be boring without him. His model makes another cameo in Ghosts; albeit with no face.
He makes two appearances in Salty's Lighthouse, first getting bumped by Warrior and telling him to watch where he's going, and then in a flashback where Top Hat, Warrior, and Otis were remencing also getting bumped.
