In Clu Clu Land, the player is an female balloonfish named Bubbles who swims around in a maze trying to uncover all the golden Ingots.
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 gold ingots in each stage while avoiding the Unira and Black Holes. Ingots usually form a shape such as 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. Bubbles can stun the Unira by using a Sound Wave. When they are stunned, Bubbles 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 when Bubbles falls into a Black Hole, or when time runs out. The game ends if 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 will alternate between their uncovered side and a dull side.
The Famicom Disk version is based on Vs. Clu Clu Land which was released for the coin-op Nintendo Vs. System. It contained twice as many puzzles, a new enemy (Boss Unira), different level themes, and some other adjusted game features.
This is the last licensed game that was released for the Famicom Disk System. Because of this it is arguably the rarest Famicom Disk system game and sells for a large amount of money.
