Super Mario Bros – World 4-3
Mushroom platforms replace the trees, and they are narrower. 4-3 is the athletic stage of world 4: scales, red Koopas on small ledges, and long drops between the stalks.
Scales behave the same as in 3-3, but here some of them are the only way across a gap, so you cannot avoid them. Step on, let the platform sink a little, jump from the top of the swing. The second scale usually gives you enough height to reach the next mushroom if you jump early.
The 300-second timer is enough if you do not backtrack. There is a Super Mushroom in a question block around the middle of the level, sitting on a platform that is easy to miss if you are already in a rhythm of jumping. The stage ends on a wide platform with a normal flagpole.
