Clu Clu Land

The player controls a female balloonfish named Bubbles, known as Gloopy in Japan, who swims around in a maze trying to uncover all the golden Ingots. The story starts with a type of sea urchin , the Unira, stealing all the treasures in the underwater kingdom of Clu Clu Land. Bubbles, the heroine, sets out to retrieve the treasure. The objective is to uncover all the gold ingots in each stage while avoiding the Unira and Black Holes.

Ingots usually take the shape of a heart or a mushroom. The only way Bubbles can turn around to change directions is by means of Turning Posts located throughout the stages. She can stun the Unira by using a Sound Wave. When they are stunned, she can push them into a wall to get rid of them and receive points.

If Bubbles is hurt by the Unira, she will lose a life. A life is also lost if she falls into a Black Hole, or if time runs out. The game ends when Bubbles has lost all her lives. In later levels, the player must pass over the ingots an odd number of times to uncover them, as they alternate between their uncovered and dull sides.
