Bob-omb Battle Factory is the 14th main stage in Super Mario Star Road, is is a factory level run by bob-ombs. This level is located on the star road, which you can enter once you have 65 stars by entering the star cannon in the center of the observatory. Once on the star road, Mario must locate a warp pipe with 2 black bob-omb (which are killable, but don actively attack Mario). This stage has a lot of gimmicks, including arrow platforms, walkable walls, wind, and much more. There are also various signs int he stage to take note of, one giving a hint to the vanish cap outside a locked door (no, it is not an alternative entrance into the level), and one warning the player about using shortcuts (this is because of invisible walls over toxin quicksand waste).
