World 1-1 (Super Mario Bros. 3)

Level 1
This is the first level in the game. You start out as small Mario and encounter the first Goomba in the game. Thre are two blocks one with a coin and one with a mushroom. Further down is a block containing a super leaf which can only be opened by a Koopa Troopa. Use it and run all the way to the right to fly over the gap and get the 1-up mushroom. Then fly into the top pipe to get the coins shaped like a three. Exit is on the right.
