A guide to completing World 7-2 in Super Mario Bros 2 for the Nintendo Entertainment System.

Enter the Castle

Go to the right, past three Snifits, then go to the right and enter the castle door.

Explore the Castle

A conveyor belt will start taking you toward the right. Beware of the vase on the right that has Shyguys coming out of it. Go past the vase and be careful of the three Ninjis on this conveyor belt.

On the next conveyor belt, there is a vase with Bob-ombs coming out. Be sure to hold the B button to run past the Bob-ombs so they won't bump into you when they turn around to chase you.

After that, you have to choose whether to take the lower path or the upper path. If you want to take the lower path, try to stand on a Bob-omb so you're on the right side of its head, and it will walk to the right, where you can jump off and go down the chain that is just after the conveyor belt with the Bob-ombs. If you want to take the upper path, ignore the chain leading downward, then go to the right on the conveyor belts, get past the Pansers and their fireballs, then climb the chain.

Lower Path

If you chose to take the lower path, you have to pick up a Mushroom Block, but try not to let the Spark hit you. You can throw a Mushroom Block at it to get rid of it.

Next, there are several Cherries on the way down. To get them, you need to pick a Mushroom Block on the correct side. The order that you find Cherries is as follows:

1. Left
2. Right
3. Right
4. Left

After that, the path is no longer split, so just pick Mushroom Blocks and get a final Cherry, then go through the door at the bottom.

Go to the right, past the chains and the Sparks. Go through the door and go to the left, and pick the leftmost grass to get a Potion. Take it to the left and drop it, then go through and get the Mushroom from the column. Then exit Subspace and exit this room to return to the room with Sparks and chains. Go to the right and go through the door.

Climb up the chains and be careful of Sparks as you try to get Cherries and go up more chains (but the Starman might appear within the wall, making it impossible to actually get it). Go through the door at the top.

Go left, past more chains and Sparks, be especially careful of the final Spark that goes up and down, and climb up the chain at the end.

This room has a lot of conveyor belts and enemies, and a spike platform about halfway up the room. You may need to go to the leftmost side of the conveyor belt below the spike platform, crouch until flashing, then jump straight up to reach the conveyor belts to the right of the spike platform. Then, continue to carefully make your way up while avoiding the enemies. At the top, climb the chain, and you find a Red Birdo.

Red Birdo

Red Birdo spits several eggs in a row, and sometimes spits a fireball instead, so pick up an egg, but before you throw it, wait for Birdo to stop spitting eggs for a moment. Throw eggs at Birdo until it's gone. Then go to the left and climb up the chain.

You might want to do a Power Squat Jump to reach the block above the chain, then jump to the right to get past the Sparks. Go to the right, past the locked door, and go through the unlocked door. You'll find another Red Birdo. Defeat it as before, and pick up the key that it drops. Go through the door. Throw the key at the Sparks on the left, then pick up the key again, go to the left and unlock the door. Then skip ahead to Reach the Boss.

Upper Path

If you chose to go up the upper path, you will have climbed a chain after getting past some grey Pansers that spit fireballs, and you are now in a room with chains and Sparks. Carefully get past the Sparks, running past the two that go up and down. Go up the leftmost chain to reach the next room.

Go to the right and climb the chain, then fall to the left and press Up to grab the upper chain. Climb up.

Go the left and carefully run past the Sparks going up and down between all the chains. Then jump and climb the leftmost chain to go to the next room.

Jump up the platforms with Sparks on them, then you will see a chain on the left and a chain on the right. If you don't want a Mushroom, go up the chain on the right, and skip to the next paragraph. If you do want a Mushroom, go up the chain on the left and you will reach a door. Go through, then fall downward while staying just to the left of the ladders, then go down the ladder at the bottom to reach a door. Go through, then pick the rightmost grass, take it to the left side of the room, drop it and go through the door, then get the Mushroom from the left column. Then exit the room, go up the first ladder, walk left so you're in front of the structure, and jump up so you're to the right of the Panser. When there is a gap in the fireballs, jump up to the nearest ladder, then climb up and go through the door at the top. Then do a Power Squat Jump to reach the platform above the door.

Keep making your way up the platforms and columns, then climb up the chain at the top of the room and go through the door.

Go to the right, drop the POW block to get rid of the Sparks, then go to the right side of the room and climb up the chain, then go to the right.

Carefully go along the conveyor belt, ducking under or jumping over the Sparks as needed. At the right side of the room, go down the chain.

Red Birdo 2

You'll find a Red Birdo. Red Birdo spits several eggs in a row, and sometimes spits a fireball instead, so pick up an egg, but before you throw it, wait for Birdo to stop spitting eggs for a moment. Throw eggs at Birdo until it's gone. Pick up the key that it drops, then go through the door. Try to drop the key on each Spark individually so the key won't get stuck underneath a block and force you to go back and try to get another. When the Sparks are gone, pick up the key again, go to the left and unlock the door.

Reach the Boss

Go to the right and pick up the crystal ball. The mask gate will come to life and start floating back and forth! Go to the left and pick up a Mushroom Block and throw it at the gate. Keep hitting the gate with a Mushroom Block, and after a while, it will stop moving and open its mouth. Go through to face the final boss, Wart.
