Spine Coaster Stowaways

Spine Coaster Stowaways, or Rock-Candy Mines-6, is the sixth level of Rock-Candy Mines in New Super Luigi U. It is unlocked when Smashing-Stone Tower is completed, and its completion unlocks Sumo Bro's Spinning Tower.

Layout
The level starts in a mountainous area with a Spine Coaster which Luigi and company must ride to get to the end of the stage. They must avoid poisoned water and several Piranha Plants and related enemies that block their way and occasionally move onto the tracks as they reach the Goal Pole. The player also can use the P-Acorn without riding the Spine Coaster.
