World 5-Castle, or simply World 5-6, is the twenty-eighth level of Super Mario 3D Land.
This level opens with Mario traversing a long pass of moving platforms. These platforms cross a vast lava plain, and at points will fall into said plain. Several Dry Bones await Mario on this crossing as well. The second challenge in this level is that Mario must run under several Thwomps. Afterward, Mario must cross another set of moving platforms, these spinning around over lava, and across these platforms is the Checkpoint. Mario must then move past two more Thwomps and even past a Hammer Bro. At the end of this long windy path, Mario will confront Bowser again.
Enemies that appeared in World 5-Castle:
The boss begins as Mario approaches a large, grey, moving platform. As the battle commences, like the rest, Bowser starts to shoot out fire balls at Mario. Once over the bridge, Bowser will jump around, getting close to Mario and attempting to attack Mario with his tail and fire breath. The final bridge to the castle is broken up into several platforms, some of which aren't in a straight line. Bowser will try to pounce Mario as he travels this final bridge.
- Star Medal 1: Atop the second Thwomp in the level, Mario can find the first Star Medal.
- Star Medal 2: If Mario proceeds down from the group of spinning platforms past the first set of Thwomps, Mario will easily obtain the second Star Medal.
- Star Medal 3: At the end of the moving platform with the second set of Thwomps, Mario can nab the third and final Star Medal.
