Submarine floats on water’s surface near a rocky shore. A sailor looking out the top of the submarine uses telescope to look at rocky cliff. The sailor descends into the submarine, turns the submarine’s levers, and submarine submerges. Seals on rocks look on. A sailor steers the submarine past rocks, fish, and sea anemones. A ladder descends to the sea floor. A scuba diver goes down the ladder, picks up another scuba diver lying there, and climbs back up into the submarine. The sub drives away.
