Marine Research Lab

The Marine Research Laboratory is a laboratory stationed in Great Bay of Majora's Mask that specializes in water quality and marine life-forms. Inside is a giant water tank especially prepared for Zora Eggs, and in a corner is a smaller fish tank with two hungry fish inside.

The Professor works here, researching the creatures of the Great Bay Coast. This marine researcher is the Terminan counterpart to the man who studies at the Lakeside Laboratory in Ocarina of Time. As explained by the doctor, if the Zora Eggs aren't kept in the specifically-made aquarium, they may die. The reason for this is that Zora eggs are very sensitive to extreme changes in temperature, and since Great Bay has had abnormal weather patterns recently, they are not safe in such an environment. Knowing this, Dr. Mizumi prepared the aquarium for the eggs long ago so that they may properly hatch.

Once Link has rescued all seven of the Zora Eggs and has placed them inside the aquarium, the Zora Eggs will instantly hatch and teach him the New Wave Bossa Nova, which is needed to get Lulu's voice back.

If Link feeds the hungry fish that are inside the smaller tank, he will receive a Piece of Heart as a reward.
