World 1-1, that is also known as the first level, starts with the chosen character dropping down from a doorway suspended in mid air. At the bottom of the screen, there is another doorway, which leads outside. It's a simple level with enemies like Shy Guys, Tweeters and Ninjis. 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. Birdo is fought at the end.
