'''Roy's Conveyor Castle''', or '''{{world|Rocky|castle}}''' is the castle of [[Rock-Candy Mines]] in ''[[New Super Mario Bros. U]]''. It is unlocked when [[Shifting-Floor Cave]] is completed and its own completion opens the path to [[Meringue Clouds]] and [[Land of the Flying Blocks]]. Additionally, the course can be entered via a [[! Switch]] bridge to the back door of the castle. The boss of this stage is [[Roy|Roy Koopa]].

The level begins near a pit of [[lava]]. An [[Iron Block]] falls from a [[Conveyor Belt]], acting as a platform in the lava. The player can climb the Conveyor Belts and go left to find a [[Hidden Block]] containing a [[1-Up Mushroom]]. A [[Dry Bones]] is found, and more Iron Blocks fall from the Conveyor Belts above. A [[Bony Beetle]] is found, followed by a section where Iron Blocks infinitely drop from Conveyor Belts. Another Bony Beetle is encountered, and Iron Blocks are used to move across a portion of lava. Towards the end is a [[Brick Block]] that contains a 1-Up Mushroom. A Dry Bones is found, along with a [[Red Ring]] and more Iron Blocks. The [[Checkpoint Flag]] is then found. [[Lava Bubble]]s are found jumping out of some lava pits. A [[? Switch]] is found, and when it is hit, Iron Blocks with Dry Bones on them fall on top of the surface of the lava, allowing a platform at the end of the section to be reached. The boss door can then be found.

The boss door leads to an area with a cannon, which launches the player to [[Roy|Roy Koopa]]'s airship. Roy attacks by shooting [[Bullet Bill]]s from his [[Bill Blaster]] while jumping between horizontally-moving platforms in the area. Occasionally, he launches [[Bull's-Eye Bill|Missile Bill]]s. After being jumped on three times, Roy is defeated.

|While floating on an Iron Block in the middle of the level, the player must wall jump to a hidden [[Warp Pipe]] which leads to a hidden room. After entering the hidden room, the player must act quickly by dashing to the second Star Coin and back before an Iron Block falls.

|Access to the third Star Coin requires the secret entrance into the back of this castle on the world map. Next, Mario must step on a ? Switch in order to cause a bunch of Iron Blocks to fall overhead. After that, Mario can now walk on top of the Iron Blocks and get the third Star Coin before the last Iron Block falls and blocks the path to the Star Coin.

==Second entrance==
The second entrance is automatically unlocked upon completion of [[Screwtop Tower]]. However, it will not be accessible under normal circumstances as all paths to the second entrance requires the use of the red [[Stretch Block]]s to the right of Screwtop Tower, which is impossible to have been stretched when Mario is at Screwtop Tower because the south path leads to a blue switch which would have been automatically stepped on and the west path leads to blue Stretch Blocks which must have been used to cross the abyss, and there are no red switches nearby. To get to the second entrance, the player must do one of the following (in addition to completing Screwtop Tower):
# Complete [[Waddlewing's Nest]] and [[Thrilling Spine Coaster]] (which requires locating the secret exit in [[Grinding-Stone Tower]]). The player can then step on the red switch to the east of Waddlewing's Nest and use the secret path through Thrilling Spine Coaster to reach the now stretched-out red Stretch Blocks and the second entrance.<br>or
# Find the secret exit in [[Walking Piranha Plants!]]. This unlocks a path to a red switch and bypasses the blue switch between Walking Piranha Plants! and Screwtop Tower.
