World 6-1 (Super Mario Bros. 2)

World 6-1 is the first level of World 6 in Super Mario Bros. 2.

Layout
This level starts like any level from World 2 does: as the desert is explored, numerous enemies and obstacles must be beaten, such as quicksand and swarms of Cobrats and Pokeys. Then a fort is entered, where 21 jars are seen. Only one of them has the key that is necessary to open the door showing Birdo's whereabouts. Another jar leads to an extra life. Birdo shoots fire only.
