You play the role of young Adam, who joins Delphineus the dolphin, on a quest to find the great whale, King Cetus. First you must gain the trust of the citizens of Eluria before they'll help you. Next you are to fulfil the prophecy of the Oracle and to save Eluria.

You begin the quest at your home. Talk with your father. Look at the seagull. Poor thing, it's covered with oil. Take the detergent and the rag beside the box. Pour some detergent on the rag and use it to clean the seagull. Before your father leaves, he'll pass you a bottle of fertilizer and a transmitter. Look at the tank of water.

Use the trident to poke the three eyes. Talk to the Oracle when it appears. Arrange the mosaic. The Oracle will then ask you three riddles and tell you to click on the picture to answer it. In the original author's case, the three answers were: MAN, FISH and LOVE. They may not be the same for every game. The oracle will tell you to gain the trust of the citizens of Eluria before it tells you the prophecy.

Swim outside. Enter the building with a few pillars. Talk to the golden mask. Turn the pillars until all nine parts are in the correct position. Talk to Superfluous the hermit crab, then exit.

Swim right until you reach the anemone, then enter the cave there. Look at the key on the skeleton. Pull the pike out (twice). Open the chest to free the crab. Swim out from the cave. Try to get the key, but you're too late, the red fish has swallowed it. There's no need to follow the red fish immediately.

Since the anemone can't digest the key, it's regurgitated. Get the skeleton key. Go to the giant head. Use the bottle on the ear to catch the flashlight fish.

Swim to the toxic cave. Release the flashlight fish to light up the cave. There's a brick wall inside the cave. Remove the brick one by one until you see something among the rocks. Look at the rock, there's a metal box hidden there. Use the oily rag to ease the lock, and then open it with the skeleton key. There's a suit inside, get it and wear it. Enter the hole. Attach the following together: floating bulb, transmitter and cable. Then tie them to the barrels of toxic waste.

Swim through the toxic cave to reach the boat. Use the trident to open the cabin door. Watch out, there's a flesh eater behind you. Swim all the way until you're caught in the drift net.
