Husks are browngray and spawn in deserts and Strays are gray and spawn in snow biomes . I feel like the Brisk should have a different colour pallette and spawning biome to the Stray . <| sep |> I think it was the USS Seawolf was converted to do this in the late 70 ' s 80 ' s . I read a book about a person that served on it when they were setting it on the bottom to tap an undersea cable in russian waters . The device at least in the late 70 ' s 80 ' s was nuclear powered . Was a very cool book . They have a few subs now specifically built for this purpose . They came across an unseen russian submarine and collided with it when they were trying to go around it and send a diver the author in a rebreather unit to photograph it . Also you only mess up flushing the toilet ONCE ! ! If you do it wrong you get covered head to toe and hope like half a dozen crewman give you their shower water ration .
