World 1 (Super Mario Bros. 2)

World 1 is the first world Mario, Luigi, Peach, and Toad venture through in Super Mario Bros. 2. It is divided into three levels and inhabited by Tweeters, Shy Guys, Snifits, and Pidgits. At the ends of the first two levels, the heroes have to face the egg-spitting Birdo, and Mouser at the end of the last level. It tends to have waterfalls with log bridges.

World 1-1
World 1 starts with the character (the player chooses) dropping down from a doorway suspended in mid air. At the bottom of the screen, there is another doorway, which leads outside. There is an extra 1-Up disguised as a plant next to a POW on top of a hill. There is a shortcut to Birdo that can be found in the cave area halfway through the level. After climbing up the vine, instead of exiting to the right to the normal exit, jump across the waterfall and use bombs to blow up blocks. After going through the door on the other side, proceed to the right and Super Jump over the wall on the right side of the screen, where Birdo is faced in.



World 1-2
At the start of the level is a Magic Carpet that needs to be hijacked in order to get across the large pit. Afterwards there are two vases - the first has a 1-UP at the bottom, and the second has a key for opening the locked door. Beezos will try to knock player off the Magic Carpet in this level. Inside the cave, the player have to crumble walls. When leaving the cave, there are a lot of veggies. After the player goes through the door, they will find a pink Birdo that spits only eggs.

World 1-3
This level features a hidden warp to World 4. Right before the castle, there will be a cluster of plants, one of which is a magic potion. Take the magic potion past to the far right of the screen, past the castle, to a vase. Use the magic potion to create a door, enter the door, enter the vase while still in dream land, and the player will be warped to World 4.

For the normal exit which will lead to World 2, enter the castle as normal and at the end to face Mouser.
