World 5-Castle (Super Mario 3D Land)
From the Super Mario Wiki, the Mario encyclopedia
World 5-Castle is the sixth and final level of World 5 and the twenty-eighth level in Super Mario 3D Land, and the second castle to appear in the game. A Tail Bowser is once again faced as a boss. 50 Star Medals are required to access this level.
In the start of the level, Mario sees two Brick Blocks and, after going up on an elevated floor, faces a Dry Bones. Near this place, he must go up on moving sinking platforms and under a swinging spiked cylinder and a Baddie Box. A cement area is found soon after this, where Mario encounters Brick Blocks, a Draglet, and three Thwomps. Going to the far right, Mario must ride wire moving rotating platforms, under another Baddie Box and a Red Ring. Jumping to a stone area, he sees three Lava Bubbles, a Checkpoint Flag, and a pair of binoculars. On the left side, there are more moving platforms and Thwomps. Soon after, a stationary ground with another Draglet and a Hammer Bro is there. After Mario crosses rising boards and Lava Bubbles, the Tail Bowser battle starts. The corridor is composed of moving platforms, a cement floor, and a bridge. After Mario hits the switch, he saves the two Toads (Green and Yellow), and the Tail Bowser is revealed to be a Magikoopa. Mario must enter a Warp Box to reach the top of a tower, where a + Clock and the Goal Pole are standing.
