Super Mario Bros.: World 8-1

You'll encounter some Buzzy Beetles, Goombas, and Koopas as you go along. If you see 2 coins above 3 Goombas by a pipe, go down that pipe for coins underground. Return to the surface and you'll see a Paratroopa between walls. Hit an invisible block then the block above it for coins. One garbage block at the next set has a Star. There are several holes to cross plus many enemies ahead. After you go far, cross a broken stairway and you'll find the flagpole.
