Larry's Trigger-Happy Castle, or Sparkling Waters-Castle, is the Castle level of Sparkling Waters in New Super Luigi U. It is unlocked by completing Dragoneel Depths and its own completion will unlock All Aboard!.
Luigi begins the level in front of an area that fire Banzai Bills. Some Brick Blocks and a ? Block are found, followed by two Bill Blaster Turret. A pit of water with Torpedo Teds in it can be found in between them. Two Brick Blocks, one of which contains a power-up, can be found. A Hidden Block containing a Mini Mushroom is above the Brick Blocks. A Warp Pipe is found, and it leads to an underwater area. Two groups of Brick Blocks are found along with some Search Torpedo Hasshadai that release Targeting Teds. A Warp Pipe that leads to the next area is then found. A ? Block is found next to a wall made of Brick Blocks. A King Bill then destroys the wall, and Luigi must jump on Brick Blocks floating above the water to avoid it. The boss door is then found. Luigi must fight Larry Koopa, who battles the same way he did in New Super Mario Bros. U.
