'''World A-4''' is the fourth and final level of [[World A]] in ''[[Super Mario Bros.: The Lost Levels]]'' and the eighth secret level overall in said game.

The player starts before a group of pillars with the first three having [[Fire Bar]]s in them (the third Fire Bar being longer than the others), a [[Lava Bubble]] jumping up between the first two, and a [[? Block]] with a power-up above the second pillar. Through a passage with a Fire Bar on the ceiling, the player will arrive at a large pit of [[lava]] with a Fire Bar before it and a Lava Bubble jumping up from the lava; to cross, the player has to time a jump off of the Fire Bar. After a narrow passage at the top of some stairs with a [[Koopa Troopa]] are narrow pillars the player has to jump between while avoiding Lava Bubbles (it is, however, possible to potentially defeat up to two of the Lava Bubbles, though otherwise invincible, by kicking the Koopa's shell at them, but they will immediately respawn soon afterwards). The player then has to pass through a narrow passage with [[Bill Blaster]]s, two on the floor and one on the ceiling. By running and then jumping off of the third Bill Blaster, the player can cross the lava pit and reach the [[Impostor Bowser|fake Bowser]], who [[Bowser's Flame|breathes fire]] or throws [[hammer]]s (''[[Super Mario All-Stars]]'').
