Super Mario Bros.: World 8-2

The start has a stairway with an incoming Paratroopa and a Lakitu dropping Spinies. You'll next see a spring under a long path of garbage blocks. Up ahead are Bullet Bill cannons, Paratroopas, and Buzzy Beetles. Dash and jump to cross a big hole and go down the pipe for coins underground and you'll see more cannons back at the surface. A Paratroopa comes from a broken stairway. Keep jumping to avoid falling through the stairway then you'll find the flagpole.
