World 9-3 (Super Mario Bros.: The Lost Levels)

World 9-3 is the third level of World 9 in Super Mario Bros.: The Lost Levels. This is the only level in the game that is set in the overworld, but has a castle color scheme and music theme. In Super Mario All-Stars, however, it uses castle interior tiles with the overworld color palette, making them appear brown.

Layout
The level is a long structure, devoid of any enemies or obstacles other than Blue Bowser (Fake Bowser in the Super Mario All-Stars version) before the Goal Pole. There is a Springboard near the start of the level that can help the player get on top of the structure's ceiling. Soon after the Springboard is a Brick Block containing a Beanstalk that leads to Coin Heaven; a Warp Pipe later on will also take the player to Coin Heaven.
