A guide to completing World 6-2 in Super Mario Bros 2 for the Nintendo Entertainment System.
Cross the Sky
Go to the right and jump up the ledges, and go through the door to go outside. There are two main ways to proceed: Pick a Veggie and Ride the First Albatoss or Ignore the Veggie and Ride Left on the Third Albatoss.
Pick a Veggie and Ride the First Albatoss
Run to the right and try to quickly pull the grass to get a large veggie, but don't throw it. Hold onto it and quickly jump onto the Albatoss that is going to the right. Then you need to jump over the three Albatosses going the other way, then jump back down onto the Albatoss that is going to the right. When you find a green Panser, you need to throw the large veggie at it to go safely past, then jump over the platform and get back on the Albatoss. Finally, when you see a tall ledge on the right, crouch until you're flashing, then jump straight up to do a Power Squat Jump so that you land on the ledge with the two pieces of grass. Then skip ahead to Get a Mushroom and a Coin.
Ignore the Veggie and Ride Left on the Third Albatoss
You can run to the right, ignoring the tuft of grass, then jump up on the three Albatosses that fly toward the left. Get on the topmost Albatoss and let it take you to the left, then you can jump on an Albatoss that is going to the right. Let this Albatoss take you to the right, then after you go past the green Panser, you need to jump over a Beezo. You'll reach a ledge with two tufts of grass. If you don't want a Mushroom and a coin, you can ignore the tufts of grass and just stay on the Albatross, and skip ahead to After the Two Tall Ledges.
Get a Mushroom and a Coin
Don't pick the rightmost grass. Pick the leftmost grass and drop it on a spot with no grass, then go through the door, pull the grass to get a coin, then jump over and get the Mushroom.
After you exit Subspace, you will have to go to the right and jump on an Albatoss going left, jump over the fireballs from the green Panser, then when you encounter an Albatoss going to the right, jump on it.
After the Two Tall Ledges
After you go past the two tall ledges (where you may or may not have gotten a Potion earlier), keep riding to the right on the Albatoss.
There will be a column of three Albatosses that you have to jump over. Then there will be three more Albatosses going toward the left that you have to jump over. If you end up on the lower Albatoss, you will have to jump up two Albatosses to reach the next ledge. Otherwise you can just ignore that ledge and let your Albatoss take you to the upper ledge. Then go through the door at the end.
Green Birdo
To the right, you find a Green Birdo. Green Birdo only shoots fireballs, so pick up Mushroom Blocks and throw them at the Birdo until the Crystal Ball pops out. Pick it up, then enter the mask gate, play Bonus Chance if you have coins, then you will continue to World 6-3.
