Smashing-Stone Tower

Smashing-Stone Tower, or Rock-Candy Mines- is the tower level of Rock-Candy Mines in New Super Luigi U. It is unlocked when Porcu-Puffer Cavern is completed, and its completion unlocks Spike's Seesaws and Light-Up-Lift Tower.

Layout
The level starts in a tower with Grrrols and multiple platforms. At one segment of the level, the player must let the Grrrols destroy some Brick Blocks to open up the rest of the level. A Mega Grrrol destroys another wall of Brick Blocks which opens up the boss door where Boom Boom awaits. He must be hit three times in order to be defeated.

Secret Exit
The secret exit is found by entering a pipe near the end of the level. Then once there the player must preform a Ground Pound in the slanted down area.
