Marine Research Lab

The Marine Research Laboratory is a laboratory stationed in Great Bay of Majora's Mask. Inside is a giant water tank specially prepared for Zora Eggs, and in a corner is a smaller fish tank with two hungry fish inside. If you feed the fish, it will eventually give out a Heart Piece.

Dr. Mizumi works here, researching the creatures of the Great Bay Coast. This marine researcher is the Terminan counterpart to the man who studies at the Lake Hylia Laboratory in Ocarina of Time.
