World 5-4 (Super Mario Bros.)

World 5-4 is the fourth and level of World 5 in Super Mario Bros.

Layout
World 5-4 is similar in layout to World 2-4, but with additional Fire Bars and Lava Bubbles.

The player starts at the top of some stairs that lead to a pit of lava with Lava Bubbles jumping out and platforms placed above it. Above the center platform is the only ? Block in the level, containing a power-up, and the platform also has a long Fire Bar that can reach the other surrounding platforms. After the lava are two paths lined with Fire Bars, with the bottom path having more than the bottom. Next are two lifts moving in opposite vertical directions with Fire Bars on both sides, followed by some gaps and Lava Bubbles before coming to the Fake Bowser, which breathes fire as the player is jumping across the gaps.
