Super Mario Bros.: World 5-2

You'll first see a Bullet Bill cannon then a spring. After a Hammer Bro, you can go down the pipe to an underwater area for coins or continue the normal path ahead. Where another Hammer Bro is on 5 ? Blocks, hit an invisible block then a garbage block to reveal a vine. The vine takes you to the sky for more coins. If you're still on the surface, you'll see 2 Hammer Bros on garbage blocks. The rest of the path has Koopas and Paratroopas. The stairway is broken with holes so cross it carefully to reach the flagpole.
