How to clear Gear Stage, also known as Fiery Blocks, in Super Mario Land 2: 6 Golden Coins.

How to Reach Mario Zone
Mario Zone is in the east part of the world map, north of the turtle and south of the pumpkin.
How to Clear Gear Stage
Go to the right, and there is a ? Block with a Koopa Troopa after it. The ? Block contains a Super Mushroom or Fire Flower.
Jump up the gears near the right wall, and there will be a spinning gear on the left. Jump onto it, then continue jumping up the gears.
There is a Yashichi (spinning blade) that goes up and down. Go to the right of it after it goes past, then go through the pipe on the right.
There are Spiked Balls on the floor, and there is nothing of interest near the floor, so stay on the gears throughout this room as you go to the right.
After a spinning gear, there is a Koopa Troopa on some non-moving gears, and after that, there are some coins. Get all the coins as you go to the right, but remember not to stand too long on the spinning gears or you will fall down below.
To the right, there are six coins, a Koopa Troopa, another set of six coins, and a ? Block that contains one coin.
After the ? Block, there is a Tatenoko (spinning blade) that goes left and right. When it's going left, try to jump to the right of it and land on a spinning gear, then carefully get the coins above the gears and jump off onto the block on the right side.
Just after that block, there is a Koopa Troopa walking on top of some gears. Jump across the two spinning gears after that, then go through the pipe on the right.
Hit the ? Block and get the Carrot, then jump and hold the jump button to float down so you can hit the Midway Bell and reach the right side of the room without falling on the Spiked Balls below. Go through the pipe on the right.
Go to the right and you find two Koopa Troopas walking on gears. Go to the right and jump up on the blocks, and fall through the gap. Wait for the blade beneath you to go to the left past you, then jump up to reveal a Hidden Block in the gap above you. A 1-Up Heart comes out. Follow it and take it.
To the right, there are Screws that fly up and slowly bounce up and down. The ? Block on the left contains a Super Mushroom or Fire Flower. The rest of the ? Blocks all contain coins.
Go to the right and make your way up the gears, and when you reach the Fiery Blocks, if you're still Fire Mario, throw fireballs at the Fiery Blocks to break them. Jump up to hit the normal Bricks and break them as well. Make your way through the passageway, breaking Fiery Blocks and Bricks, to get a lot of coins. At the end, break the upper block first, then the lower block, so you can get a 1-Up Heart. Then run and jump past the spinning blade when it is moving toward the left, and get on the gear beneath the ? Block.
If you aren't Fire Mario or didn't want to go through the coin passageway, go up the gears until you are on the gear beneath the ? Block at the top.
Hit the ? Block to get a Carrot. As Bunny Mario, hold the jump button to float down through the coins on the right while avoiding the Spiked Balls. Then hit the Bonus Bell to complete the level. You will play Mario Catcher, which just has Super Mushrooms, a Fire Flower, a Carrot, and some 1-Up Hearts.
After the Level
After you complete this stage, you can continue to Rubber Ball Stage or go to any of the following:
