Stomp the Koopa Paratroopa and kick it to the right for a chance of collecting a 1-Up. But remember to jump over the Red Piranha Plants to climb out of the pipes along the way.
If World 6 is your destination, you can take a shortcut at the very beginning of this section. Pop up the vine and bounce off a Koopa Paratroopa for a boost to the top. First you'll be taken to Coin Heaven B, and when you're done, you'll arrive at the World 6 Warp Zone.
Otherwise, you must find a way to scale the massive wall blocking your progress to the end of the level. Two well placed jumps will reveal hidden Coin Blocks that you can use as stepping stones.
When moving platforms are three circles long (as opposed to the standard four or six), keep in mind that an entire column is one sprite.
The two platforms in one column will always move in uniform. There is only one sequence that will repeat itself.
You will also notice that these platforms are restricted, compared to other platforms. While the objects in the sprite will move, the sprite itself is frozen! Therefore, it cannot go higher than the top of the ceiling - it will just cut off.
Watch out. If you kick the Koopa's shell to the right under the set of "?" blocks and drop down to the floor, there's a good chance that the shell will bounce back and hit you.
It's not shown in the picture but try to avoid hitting the brick to the right of the last coin, or you may uncover a poisonous mushroom.
To collect a 1-Up, be sure to grab the Starman found at the beginning of this section. Then jump on top of the second pipe, and hit the brick in the high right corner. As soon as you make it appear, run to the right and grab it when it drops.
Jump from the first rising platform and make the vine pop up from the brick. Then ride the platform again, leap over to the vine, and climb to the Warp Zone which leads to World 8.
If you decide to take the standard exit in this level, right next to the flag pole there are two invisible blocks stacked on top of each other use these to either get a 5000 or a 1 up if you jump high enough.
However, if you jump up to the ceiling and dash past the exit pipe, you will find yourself reaching another Warp Zone which will take you to World 7.
The first leg of this world will continue to repeat, starting at the platform, until the correct exit is found.
You'll need to make it to the very high pipe in this section to reach a narrow Coin-filled passage, coin room E, and the rest of the stage.
The one advantage to passing through to the end of this section is that there is a hidden Power-Up on the tall bluff. It also resets automatically, so you could also collect a Fire Flower here.
The Lost Levels are notorious for their challenging passage. This is where they really start to earn their reputation.
In Vs. Super Mario Bros., with the first fire-bar there is low clearance on both sides which might make it difficult if you are fire Mario or big Mario.
In order to safely collect the Power-Up, run to the right to make the Fire-Bar scroll off the screen. Then move back to the left to claim the Power-Up.
In Vs. Super Mario Bros., there is a podoboo in the lava pit between the first two fire-bars.
Avoid the falling platforms at the end of this section by jumping up to the top and running to the right.
