Special 1-Castle

 is the final and fifth level in Special 1, and is the fifty-third total level in the game. It is based off World 1-Castle. Upon clearing the level for the first time, the player unlocks Luigi as a playable character.

Layout
The player starts out on a platform, and must drop down onto another platform that contains a + Clock. Dropping down two more platforms leads to some rotating gear platforms and a Rectangular Coin Block that contains two Coins and a Statue Leaf. The player then proceeds to a platform that is propelled upwards by lava, and then run across a platform where they must avoid three Lava Bubbles. This leads to a platform where two Hammer Bros. reside; beyond that is a drop down to a lower platform with a Fire Bar, and finally, a platform that contains several Thwomps.

After this is a long narrow walkway that leads to the Dry Bowser fight, where the player must proceed to the switch whilst avoiding Dry Bowser's Fireballs. After defeating Dry Bowser the door to the Fortress opens, where Luigi is; the Warp Box further back leads to the Goal Pole.
