    1. Introduction
    The game is released in 1991 by Sierra Online. At the time, the graphics is 
    considered as state of the art. It still looks good nowadays. This is an 
    education game. The main focus is on the protection of the natural 
    You play the role of young Adam, who joins Delphineus, the dolphin on a 
    quest to find the great whale, King Cetus. You must help Cetus save the sea 
    from pollution and waste. First you must gain the trust of the citizens 
    of Eluria before they help you. Next you are to fulfil the prophecy of the 
    Oracle and to save Eluria.
    2. Where to get it?
    I have found a copy of the game in one of those abandon game sites. So I
    think it okay to download a copy of it. Anyway, it’s up to you to decide.
    Get it at http://www.abandonkeep.com/
    I had tried the download and it is working fine.
    3. Walkthrough
    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 leave, he'll pass you a bottle of fertiliser 
    and a transmitter. Look at the tank of water. It's full of oil, pour some 
    of the fertiliser inside and let the bacteria eats up the oil. Look at the 
    cage, the gerbil is thirsty. Get the water beside the cage and give it to 
    the gerbil. 
    Take the letter on the chair. It contains your certificate and a membership 
    card. Take the letter on the chair and dump it in the recycle box. Look at 
    the computer. Look at it a second time to play King Quest V. Get the 
    aluminium can on the table and throw into the recycle box. Pick up the 
    trash bag. Look at the blackboard. Click on the individual part of the 
    drawing for more details. 
    It's time to leave the room. Open the door with the combination number 
    9731. You are now inside the swimming pool. Read the instructions on the 
    blackboard. Talk to dolphin a few times. Get mackerel from the bucket and 
    feed the dolphin a few times. Go inside the pool and ride the dolphin. Get 
    the Frisbee and throw it at the dolphin. Play with the dolphin until it 
    starts talking. Talk to it. Its name is Delphineus. Throw the Frisbee at 
    the dolphin a few more times. Look at the propeller and see how it was kept 
    safe. Pull the lever beside the gate to open the hatch. The dolphin will 
    then swim away.
    Days Passed...
    The dolphin has return. Open the cabinet and get the swimming gear. Wear 
    the swimming gear and enter the sea. Swim around until you reach the 
    cruiser. Pick up all the rubbish with your trash bag. Pick up the bottle.
    (Note: I did not manage to stop the cruiser oil leak, email me if you had 
    done that.)
    Swim to the left until you see an island. Put on your oxygen tank and dive 
    into the water. Swim in the weed until you have found the city of Eluria.
    Swim to Eluria. Pick up the iron cage and gather all the rubbish. 
    Enter the temple. Get the bronze couch shell. Swim outside. Look at the 
    statue with the trident. Give the couch shell to the servant. Take the 
    trident. Go to the temple again. Use the trident to poke the three eyes. 
    The Oracle appears, talk to it. Arrange the mosaic. The Oracle will then 
    ask you three riddles and tell you to click on the picture to answer it. 
    For my case the 3 answers are MAN, FISH and LOVE. (I don't know whether 
    every time the same riddles will be asked or not) The oracle will tell you 
    to gain the trust of the citizens of Eluria before it tells you the 
    Swim outside. Enter the building with a few pillars. Talk to the golden 
    mask. Turn the pillar until all 9 parts are in the correct position. Talk 
    to the hermit crab, Superfluous. Exit. 
    Swim to royal garden. Pick up all the trash. Use the fertiliser to remove 
    the oil from the coral. The lobster, Demeter, will appear and give you a 
    healing potion. Pick up the oily shell that has just fallen. Exit. 
    Swim to fish department. Pick up all the trash, and get the cotton cloth. 
    Use the cotton cloth to clean the oily shell. Exit. 
    Go to find the hermit crab and give the shell to it. It will give you a 
    Swim to the fish department. The watchman, Gregarious, will appear when you 
    try to enter any of the department. Show the badge to it to gain entry. At 
    this time, a blowfish was caught in a plastic bag. Push it into its 
    apartment. Remove the plastic bag from it. The blowfish, Narcissus, will 
    give you some sea urchin. 
    Enter the apartment of the angelfish, Epidermis. Talk to it. Use the sea 
    urchins to eat up the algae from the plant. You get a sharp shell as a 
    Look for the apartment of the swordfish, Hippocrates. Cut the six pack 
    rings using the shell. You receive a fish bone tweezers as a reward. Pick 
    up the 6 pack rings. Cut it with the shell and then trash it.
    Look for Erraneous, the turtle apartment. Talk to it. Pull the string out 
    of it mouth and use the fish bone tweezers to remove the balloon. The 
    turtle will give you 4 screws. Put the balloons into your trash bag.
    Look for the watchman apartment. Talk to it. Follow it to the surface. Talk 
    to fisherman. Use the 4 screws on the cage and then use it to fix the 
    Return to the fish apartment. Pick up the water pump and remove the 
    additional trash. Enter Olympic, the lion head fish apartment. Remove the 
    chlorine bottle and use the water pump to clean up the chlorine. Talk to 
    lion head fish, get a spine from it.
    Now, you are ready to attend the meeting. After the meeting, get the gold 
    mask. Enter the temple. Show the gold mask to the Oracle and it will give 
    you the prophecy. Exit Eluria.
    Swim to the giant head. Pick up the mirror and remove all the trash. If you 
    have clean up all the rubbish in the game, you receive a certain award and 
    gain some additional points. 
    Swim right until you reach the anemone, enters the cave there. Look for a 
    key on the skeleton. Pull the pike out (twice). Open the chest to free the 
    crab. Swim out the cave. Get the key. Too late, the red fish swallowed it. 
    There is no need to follow the red fish immediately. So, do the following 
    task when you reach appropriate screen. 
    At the octopus place, pull the cable. Then show the mirror to the octopus 
    and then get the cable. 
    At the submarine, use the trident to open the box to get the floating bulb. 
    Pick up the fish lure. Open the storing cabinet behind the seat and get the 
    hacksaw, trash the hammerhead. 
    Swim to the toxic cave. Touch the red fish. It's will swim back to the 
    At the octopus, use the bottle on the octopus. Hide inside the plant and 
    watch what happened. The octopus has opened the bottle for you. Get the 
    Swim back to the anemone, the red fish is being eaten by the anemone. Use 
    the fish lure on it. Since the anemone can't digest the key, it got vomit 
    out. Get the skeleton key.
    Go to the giant head. Use the bottle on the ear to catch the flashlight 
    Swim to the toxic cave. Release the flashlight fish to light up the cave. 
    There is a brick wall inside the cave. Remove the brick one by one until 
    you see something among the rocks. Look at the rock, there is a metal box 
    hidden there. Use the oily rag to ease the lock, and then open it with the 
    skeleton key. There is a suit inside, get it and wear it. Enter the hole. 
    Attach the followings together: floating bulb, transmitter and cable. Then 
    tied them to the barrels of toxic.
    Wait for the divers to clear up the toxic...
    Swim through the toxic cave to reach the boat. Use the trident to open the 
    cabin door. Watch out, flesh-eater is behind you. Swim all the way until 
    you are caught in the drift net. Use the shell to cut yourself free. In the 
    meantime, the dolphin is captured by flesh-eater. 
    Swim to the boat, use the trident to open the cabin door. Enter the cabin 
    door and follow the cable until you found King Cetus. Talk to it. Swim away 
    until you see the full view of it. Click the hand on Cetus mouth to enter 
    its mouth. Use the hacksaw to cut the harpoon shaft. Swim outside and pull 
    the shaft out. Use the healing potion on the wound to save Cetus.
    Follow Cetus to the boat. Swim to the manta's cave when Cetus is fighting 
    with it. Use the shell to cut the drift net to free the Delphineus. Swim
