        "scene": "A proud tabby ship cat in a Royal Navy captain-style peaked hat sits at a wooden desk inside a cramped ship cabin, holding a white feather quill and presenting a parchment crew list. The desk contains a mug labeled 'H.M.S. AMETHYST' with an anchor, a brass spyglass, an ink bottle labeled 'INK', coins, rope, nautical tools, and a porthole in the background. A wall sign reads 'LOYAL BRAVE AND PURR-FESSIONAL'. The parchment headline reads 'SHIP'S MANIFEST H.M.S. AMETHYST CREW LIST' with a handwritten list of crew names and ranks."

        "scene": "The same tabby ship cat, still wearing the naval cap, sits upright in a wooden ship storeroom filled with barrels, hanging pans, lanterns, shelves, and warm lamplight. The cat raises one paw as if commanding or blessing a gathering of ship mice. Exactly 7 visible mice are present: one standing mouse holding a tiny white flag near the cat, two mice sitting on a shelf behind it, one mouse at lower left looking up, one mouse in the lower center foreground, one mouse at lower right foreground, and one small mouse near the standing flag-bearer. The mood is humorous and ceremonial."

        "position": "right",
        "scene": "The tabby cat sleeps curled on a naval officer's peaked cap on a map-covered desk in a moonlit captain's cabin. A warm brass lantern glows on the right, a window shows a dark blue night sky with a full moon, and the walls hold a framed sailing ship picture and nautical decor. A partly visible sleeping naval officer rests in the background with the face obscured by a plain brown square. A small medal or tag near the cat reads 'DICKIN MEDAL 1949'."
