Front Door

Front Door is a level in Super Mario World. It is Bowser's Castle in Dinosaur Land. Inside is a bright hallway with four Doors numbered 1 to 4. Each door leads to a different room with enemies and obstacles that vary depending on which door was selected. All four rooms then lead to another bright hallway with another four doors, this time numbered 5 to 8. The enemies and obstacles will again vary depending on which door is selected. After the second set of doors, the player will find a dark room and a red block that activate a light at the top of the screen. This area has Mecha Koopas, the boss door at the end, and is the only area in the game where the player can encounter Ninjis.

Beyond the boss door is the roof of the castle, where the player must fight Bowser in his Koopa Clown Car. In the first stage of the battle, Bowser will fly around the top of the screen, throwing Mecha Koopas. The player must kick these upward toward the Koopa Clown Car. After taking a hit, the Koopa Clown Car will fly off-screen, and a bunch of fireballs and a Mushroom will appear, the Mushroom being trown by Princess Peach. The Koopa Clown Car will then try to hover above the player, and drop Big Steelys on Mario. However, one out of every three times something is dropped, it will be two Mecha Koopas. Again, the player must kick the Mecha Koopas up toward Bowser. After another round of fireballs (and another Mushroom), Bowser and the Koopa Clown Car will start bouncing on the ground, trying to land on Mario. Eventually, more Mecha Koopas are thrown and the player must again kick one into Bowser, defeating him. Several fireworks appear, one being heart shaped, as Peach kisses Mario (or Luigi). The screen then begins to show the credits.
