World 6-2 (Super Mario Bros. 2)

World 6-2 is the second level of World 6 in Super Mario Bros. 2. This is the only level in the game where Albatosses never carry Bob-ombs like they normally do. In the Super Mario All-Stars and Super Mario Advance ports, this level's overworld's background is the hills similar to the roof area of World 3-3, but recolored purple since it's in the night setting, despite the adjacent levels in this world are desert-themed like World 2. However, the underground areas in the beginning of the level and the battle against the Green Birdo have the barren rocky underground background like any other desert level.

Layout
The player needs to ride an Albatoss to the right until they reach a platform that contains a magic potion, which will provide one coin and one mushroom. Then after riding another Albatoss going to the left until the player reaches a third Albatoss, they must jump to the third Albatoss and continue to the left. Riding that Albatoss to the end of the screen, the player will encounter Birdo, who shoots only fireballs.
