World 8 (New Super Mario Bros.)

World 8 is the final world of New Super Mario Bros. Mario and Luigi traveled to this world in New Super Mario Bros. after defeating Monty Tank and/or Lakithunder, or using the W8 cannon in World 5. The boss of this world is Dry Bowser. He acts like regular Bowser, but he also throws bones. This makes it hard to jump over him. There is also a very simple way to defeat him, as Super/Fire/etc. Mario can simply run through him and trigger the Skull Switch. Then, after Mario or Luigi defeat him, a new bridge appears outside, and they head into a volcano.

After traversing through four more levels, they reach the second tower, filled with serpentine platforms. Finally, they reach Bowser's Castle, separated by other castles by its size and green color. At the boss fight, there is a brief animation of Bowser Jr. laughing, then putting Dry Bowser's remains into a cauldron (which resembles a scarecrow/Clown Car hybrid). A larger-than-life Bowser exits. Bowser and Bowser Jr. turn around and look at Mario, and start the final boss fight (An unfair 2 vs 1 battle). After that, Peach is freed and gives him a kiss, and the credits begin to roll.

8-1
The first level in World 8 takes place on a barren wasteland, filled with Crowbers, and also has Bullet Bills, Banzai Bills, Boos and Splunkins. The first star coin is accessed by putting a spring on top of two blocks quite near the start. Mario will bounce up to the coin and drop down near the blocks. The next star coin is after the midway point, near a Boo. Mario has to jump on top of on top a bullet bill to reach the coin. The final coin is very close to the second, and directly underneath the path of a Banzai Bill. Mario must wait for the Banzai Bill to go over him, then jump down and get the coin.

8-2
The next level is an underground level, with ? Switches that causes water to rise inside. The only enemies in this level are Skeeters. There is also a pipe which can be gone down if Mario is in his mini form. After one area, Mario goes to an area with many sinking barrels and Skeeters inbetween them. After getting past the barrel area, Mario can either go down the mini pipe or a normal one. The normal pipe leads to an area filled with Brick Blocks, which he can ground pound to get the first coin.

8-3
This is an underwater level with many Unagis on a vertical stretch of the level near the start, before a horizontal area with a Mega Unagi which chases Mario/Luigi through the area. All of the Star Coins are in the horizontal area. Interestingly, probably because the level isn't atall peaceful, the underground music plays instead of the underwater theme. The level's background also looks like the underground background.

8-4
This level is filled with Scuttle Bugs and has a lot of moving platfroms. The first Star Coin is just before the midway point, on a high ledge. After going on some moving platforms, there is the second Star Coin, then an invincibility star. Mini Mario can access the third Star Coin, by going into a tiny pipe, with Micro Goombas in it. Also, there are several invincibility stars, helping Mini Mario to perform the jumps required to get the coin and get out. Then there is the flagpole

8-5
This takes place around a volcano. There is a lot of lava, as well as unstable platforms. Podoboos come out of the lava, and generic enemies (Such as Goombas and Koopas) also exist.

8-Castle
The final level of New Super Mario Bros., being Bowser's Castle. The Mario Bros, once inside, will encounter a massive amount of traps, including Rocket Engines and Thwomps. The level is the longest in the game, and some parts of it require pressing one of the many ? Switches to be found. These switches will flip the gravity of the castle upside down, and any enemy along with it. This action is required for getting to certain doors.

The second part of the castle is a long looping room, similar to the looping castles of 4-4 and 7-4 from Super Mario Bros., which can be passed by walking on the right platforms, which you can tell because there is a buzzer noise if you pass along the wrong platform. After that is the boss door.

Once inside the room, the player will encounter Bowser Jr. on a long bridge over a deep pit. He will toss his father's bones into the cauldron, thus reviving him, much to Peach's horror.

The duo will then fight Mario together, with Bowser Jr. using his usual shell-tossing tactic, and his father breathing flames behind him. After the player defeats Bowser Jr, his father will increase his attacks greatly. Mario must then run under one of Bowser's giant jumps and hit the Skull Switch at the end of the bridge, ending the fight and winning the game.
