The Invisibility Stone is an item that has only appeared in Kirby's Return to Dream Land. The character holding it cannot fly or float with it. As long as it is being held, all crystal-like walls become phased out and passable for the carrier, and its carrier is both invisible and invincible to all enemies, including aggressive and tracking Scarfys and Degouts. The Invisibility Stone will respawn in its original place if destroyed. It only lasts for a limited time, and flashes red when it is close to expiring. The Invisibility Stone is featured in the Item Challenge.
