Super Mario Bros. 2 (Japan)/World 4

Part A

 * New persistent red Piranha Plants and a flying Lakitu welcome you to a very challenging world. Be careful!
 * From this point to World 5, you can only go forward. Green Piranha Plants are history.
 * It's not shown in the picture however directly adjacent left above of the blocks with the multi-coin brick in the middle is a hidden coin block.

Part B

 * You'll have to hit the spring at the start of this section while running at super speed in order to clear the long gap ahead.
 * It's not shown in the picture however directly adjacent to the staircase is a hidden one-up block.

Part C

 * When you pop up the Power-Up Mushroom, wait for it to slide off the block, then catch it in the air.
 * The first pipe of this section leads to a challenging, Coin-filled swimming area A. Swim at your own risk.
 * The last block before the staircase contains a vine which leads to another coin heaven A.
 * Immediately to the right of the staircase, make two hidden Coin Blocks appear for extra running room on your leap to the flag.


 * This level is a source of infinite lives because the coin heaven transfers you back to the staircase after the large pool of water. You have the potential to collect 123 coins per loop.
 * If you want to try and speed things up, you can try looping with just the coin heaven. You collect only 83 coins per loop, but you might move a little faster this way.

Part A

 * When you pop up the Power-Up Mushroom, move to the right, then wait for it to drop. The Bullet Bills will not hit your hero.
 * Grab the Starman in the first brick after the cannons, and dash. You'll flatten all of the Mushroom World enemies in your path with ease.

Part B

 * If you're trying to get a Mushroom, before to collect it before you hit the final "?" Block, or you'll replace it with a Poison Mushroom.

Part C

 * Jump to avoid the Hammer Brother as you blaze through this section.
 * The first pipe in this section leads to coin room A.

 * A Bullet Bill flies through this area. Get out of its way and keep moving.

Part C

Part A

 * Collect the power-up at the beginning of this world, but don't put yourself at risk of being burned by the fire-bar to get it.
 * If you want to get past the begining gap, go back and run.

Part B

 * Three Koopas drop into the low-ceiling passage at the start of this section. Duck and jump to stomp them, but watch out for the rebound shell.
 * If you're controlling Mario, you'll have to dash and jump to reach the dangerous Fire-Bar block at the beginning of the section. Hop on, hop off, and run.
 * Be careful when you reach the lowering platform. As small Mario, use your super speed dash while pushing Right to reach safety.  Super Mario must jump from lower down.
 * Run through the middle passage at the end of this section and pop up the Power-Up Mushroom. Then drop and run to catch it.

Part C

 * You'll have the most luck in your encounter with the king if you dash under him as he jumps.
