The Final Battle (New Super Luigi U)

The Final Battle, or Peach's Castle-2, is the final course of Peach's Castle. It is unlocked from completing Current Event and its own completion unlocks Superstar Road and the Secret Island.

Layout
Luigi starts on a platform as he watches Bowser Jr. slam down on a bone platform in his Junior Clown Car, and he will continuously do this throughout the level. It sinks, then the level starts. Two Magmaws are in the lava. A Red Ring appears, and after three bone platforms, the first Star Coin appears. Multiple bone platforms appear after that, along with the third Star Coin. Then, a door appears. This leads to Bowser's door.

Luigi must work his way through the hall. He will encounter Bowser. Luigi must hit the ! Switch on the other side of Bowser. He will fall, and Luigi will progress in saving Princess Peach. Meanwhile, Kamek (assisted by Bowser Jr.) puts a spell on Bowser, which makes him huge. Luigi will make his way up stairs, and notice Princess Peach in a tower. She will call for Luigi, but bars will trap her, along with a wall covering the window with the Bowser Jr. logo. Bowser Jr. comes up, laughs at Luigi, then flies up to allow the gigantic Bowser to hop up.

To damage him, Luigi must wait for Bowser Jr. to slam down in his Junior Clown Car. Luigi must then jump on him, knocking him out. Then Luigi must hop in and the player must press to go higher. Then, when at Bowser's head, the player must press to slam down. Bowser will then go into his shell, and slide about, occasionally going higher, so Luigi can run under him. Bowser will soon pop out, breathing fire in the air. Luigi must complete this action three times to defeat Bowser.

Star Coins

 * Star Coin 1: Below some Brick Blocks, Luigi must use Bowser Jr. to slam down and break them. Then, Luigi must Wall Jump to grab the Star Coin and avoid falling in the lava.
 * Star Coin 2: The second Star Coin is located below several ? Blocks containing 1-Up Mushrooms. Use Bowser Jr. to slam down and destroy some, accessing the Star Coin.
 * Star Coin 3: Near the door which leads to the Bowser door, Luigi must wait on the third bone platform. As it goes down, Luigi will get the third Star Coin.
