The traffic is as an ocean floor, swarms of fish swimming in line moving forward with a steady pace. The bubbles quickly form and move upwards as the fish swim to their destinations when suddenly there appears to be a traffic jam in the way. A great white shark swoops in and gobbles up some of the fish as everyone is backing up and leaving the other direction. The water now has a faint red tint to it as the fish try to escape. Fortunately the hungry shark decides it has had enough and leaves in another direction. Traffic starts back up again and the fish go on with their day as usual.
