This world in New Super Mario Bros Flash is full of pipes lying horizontal and vertical too, and when you are a long time fan of the Mario series, you must know full well the dangers lurking inside these pipes. That is right! Carnivorous plants ready to take a bite on our red plumber! Look before you leap is the rule of the game here as these pipes serve as the only bridge between gaps, and they are often booby-trapped! Collecting coins will give you points, and sometimes there will be bonus areas where a lot of coins will appear for a limited time.
