World 2-4 (Super Mario Bros.)

World 2-4 is the fourth and final level of World 2 in Super Mario Bros.

Layout
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. After the lava are two paths lined with Fire Bars, with the top path having more than the bottom. Next are two lifts moving in opposite vertical directions, followed by some gaps before coming to the Fake Bowser, which breathes fire as the player is jumping across the gaps.
