A crowd of people is walking through an underwater tunnel, with fish and coral reefs visible on either side of the tunnel. The lighting inside the tunnel is primarily blue. The people are of various ages and are dressed in casual clothing. A few children are visible among the adults. Most of the crowd is looking around, presumably at the marine life displayed. Some people appear to be talking to each other. The floor of the tunnel is dark and reflective, adding to the illusion of being underwater.
