Bowser's Castle (or World 8-Bowsercnsmb) is the final castle and the twelfth and final level of Koopa Country in Newer Super Mario Bros. Wii. It is also the final level of the game, taking place in Bowser's castle, featuring Bowser Statues, floating Amps, and of course, Bowser himself.

Bowser's Castle is unlocked by completing Magmatrack Getaway. Completing it will not unlock any new levels.


This level begins in a room containing Bowser Statues. Like in Newer Super Mario Bros. Wii, they can be triggered by stepping on red skull blocks, but however, this game introduces skull walls.

In the first room is full of Bowser statues which can shoot fireballs once activated. At the end of the hallway is a lift that takes you up, but remember to avoid the skull walls to make it out alive.

Entering the second room introduces Amps. When the amps pass through the metal boxes, the boxes will become electrocuted.

Finally, in the last main room, there are lava waves which can convert Koopa Troopas into Dry Bones. Entering the Warp Pipe will take you to the checkpoint room, containing extra time. In this room also contains the Bowser statue that when entered, will take you to the boss room. The third and final 3-Up Moon can be found here, right at the top of the statue.

Boss Fight

Main article: Bowser#Battle 2

After entering the statue, Mario gets outside of the castle, where a thunderstorm is occurring. Two Question Blocks, each containing Fire Flowers, can be seen right before boss begins. When Bowser begins the fight, the first section of the three-part fight begins.

In the first phase, Bowser Jr. will fight normally, but he can only be attacked by throwing Koopa shells and throw it right back at him. Meanwhile, Bowser constantly hovers over the screen, being able to hurt you in the process. While Bowser Jr. is knocked out, either Bullet Bills can come from the left and right, or Podoboos will rain from the sky.

Defeating Bowser Jr. will commence the second phase of Bowser's final battle. The battle screen will autoscroll, and Bowser will attack by either slamming onto the ground, or by throwing Bob-ombs. Your only strategy is to try to survive and avoid his attacks.

Eventually, the screen will stop autoscrolling, commencing the third and final phase. The fight is similar to his battle in Super Mario Bros. 3. Stone Blocks are at the bottom of the arena on both the left and right sides. Bowser will try to drop wherever you are at, so try to position him to trick him into breaking the blocks and causing himself to fall.

When you succeed, a Door will spawn, leading to the room where Princess Peach is captured, and a ? Switch which releases Peach from her cage. After that, the credits will roll, showing every world in the game, once again in reverse order, just like in Newer Super Mario Bros. Wii, with the final shot being Princess Peach's castle with fireworks going off in the background. Coins can be collected in these mini-areas, and the number of coins collected will be mentioned at the end of the credit sequence.

Star Coins

  • Star Coin 1: In the first room, the Star Coin will be above a statue. Jump on the statues to reach the Star Coin.
  • Star Coin 2: In the second room, wall jump but don't forget to watch out for the amps electrocuting the blocks to reach the Star Coin.
  • Star Coin 3: At the end of the last room, use a Koopa shell and throw it at the last Star Coin.

  • The animation and the sound played when entering the Bowser statue is similar to the one in Super Mario 3D World.
  • The third and final 3-Up Moon of Newer Super Mario Bros. DS can be found in this level. If the player somehow manages to hop on top of the massive Bowser statue before the boss-fight, he or she will reach a 3UP Moon.
