Clu Clu Land's story starts with a type of Sea Urchin, the Unira, stealing all of the treasures in the underwater kingdom of Clu Clu Land. Bubbles, the heroine, sets out to retrieve the treasure. The object of the game is to uncover all the golden Ingots in each stage while avoiding the Unira and Black Holes. The golden Ingots usually form an outline of something, such as a heart or a mushroom. There are Turning Posts throughout the stage, and that's the only way Bubbles can turn around to go to another side. Bubbles can stun the Unira by using a Sound Wave. When they're stunned, Bubbles can push them into the wall to get rid of them and receive points.
