Shell's Secret is a secret place in the game Super Mario Sunshine. It resides in Noki Bay. The grandfather tells Mario that a strange dimension has entered, and Mario must go in there to calm it. The quest up to it is hard as there are lots of ropes Mario must walk on, and he must dodge some Spiky Rings on later ones.
At the top, the level starts inside of a strange box. Mario must wall jump out and jump onto the spinning platform, then the player needs to jump over to the platforms which retreat back to the wall, and Mario has to climb up a ladder. Mario must then get on a rope, and jump over to the rotating blocks, and then get to a part where he has to jump at a certain time to get to a platform. Once at the top, all Mario has to do is get to the Shine Sprite by jumping onto the rotating platforms and get on the platform where the shine sprite is. Many Mario Fans consider this to be one of the hardest F.L.U.D.D.-less shine levels in the game.
