A guide to completing World 1-2 in Super Mario Land for Nintendo Game Boy.
Explore World 1-2
Jump up onto the trees and collect the coins. Hit the ? block to get a Mushroom or Flower.
Go to the right, get a coin, and get rid of the Goombo. Up ahead, beware of the two Bunbuns that fly toward you. The Bunbuns will repeatedly stop and drop a spear beneath them. You can jump onto the Bunbuns or hit them with a Superball to defeat them.
Go to the right and get the coins. The ? block just contains a coin. Below that, there is a Bombshell Koopa, and there is another one on the tree to the right.
Get the coins, then jump up the trees to reach a few ? blocks with a Bombshell Koopa on top and a Goombo below them. You can defeat the Koopa by jumping up and hitting the block beneath it, or just stomp on it or hit it with a Superball.
Fall down through the gap just to the right of the three ? blocks. You will land on a ? block that contains a coin. Before you move on, there is a hidden block to the left. Stand just to the right of the tree on the left, then jump, and you will reveal the brick, which contains a 1-UP heart. Be sure to catch it.
Jump on the brick to reach the top of the tree on the right. Go to the right and jump onto the moving platform, and from there jump onto the next moving platform. Then get the coins to the right.
As you go to the right from here, there will be four Bunbuns.
After the Bunbuns, try to get the coins and land on the tree below.
To the right, there are Goombos walking down the pyramid. At the top of the pyramid, you can hit the ? block to get a Mushroom or Flower.
To the right of that, jump across the moving platforms and try to fall through the coins on the right.
The tree above you has a Bombshell Koopa on top. Above that, there is a Bunbun, and are three ? blocks, the middle of which contains a 1-UP heart, so be sure to get it.
The ? block in the gap on the right just contains a coin.
To the right, get on the moving platform and get the coins to the right of it.
Two Bunbuns will fly from the right. After you deal with them, go up the trees and get the two coins.
Get on the moving platform, but be aware that the platform on the right is made of Dropping Lifts, which will fall as soon as you land on them. Jump on the Dropping Lifts then immediately jump onto the door on the right so you can play the Bonus Game. Afterward, you will continue to World 1-3.
