Super Mario Bros.: World 7-4

This level contains another puzzle in which you must take a specific path. First, you'll cross over lava with falling platforms. Take the lower path, the center path on a rail platform, then the upper path to advance to the next phase. Where a fire bar is, take the upper path, the center path, then the upper path. After correctly taking the paths of the puzzle, fire will be incoming. Reach the drawbridge and Bowser will draw his hammers. Touch the axe and Toad will explain for the last time that the princess is at another castle.
