Special 1-Castle

 is the final and fifth level in Special 1. It is based off World 1-Castle. After completing the level, the player unlocks Luigi.

Layout
The player starts out on a platform and must drop down onto a platform that contains a + Clock, before dropping down two more platforms which will lead 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 Firebar, 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, leading to a Warp Box that will lead to the Goal Pole.
