'''Smashing-Stone Tower''', or '''{{world|Rocky|tower}}''' is the first [[Tower]] level of [[Rock-Candy Mines]] in ''[[New Super Luigi U]]''. It is unlocked when [[Porcupuffer Cavern]] is completed, and its completion unlocks [[Spike's Seesaws]] and [[Light-Up-Lift Tower]]. The [[Goal Pole (secret)|secret exit]] in this course leads to [[Spine Coaster Stowaways]].

==Layout==
The level starts in a tower with [[Grrrol]]s and platforms that must be climbed up to progress. Two Grrrol generators are found on either side of the area. Two more Grrrol generators are in the section following, and [[Hidden Block]]s below them must be hit in order to cause the Grrrols to destroy [[Brick Block]]s blocking the path. [[1-Up Mushroom]]s can be found in some of the Hidden Blocks. A large section of Brick Blocks follow, and is cleared out by two [[Mega Grrrol]]s. [[Pipe Cannon]]s are found, and lead to the boss door where [[Boom Boom]] awaits. [[Kamek|Magikoopa]] transforms Boom Boom's arms into wings prior to the battle. He must be hit three times in order to be defeated.
