In, the Lake Scientist is an eccentric scientist who lives in the Lakeside Laboratory located above Lake Hylia. He is a chemist, putting his knowledge into medicinal practice at his laboratory. When Link first meets the scientist, he mentions a mutual friendship with Granny, who is the old lady who runs the Potion Shop of Kakariko Village.

The pool in his laboratory is eight meters deep; he will watch Link dive and make remarks based on the depth he reaches. If Link can touch the bottom of the pool, he will give him a Piece of Heart and tell him he is the best diver in the world. Link needs a Golden Scale to do this, however.

The Lake Scientist is a part of the Biggoron's Sword Trading Sequence. After an Eyeball Frog is given to Link by King Zora, he must rush down to the laboratory and give it to the scientist. At first, he excitedly thinks the frog is for making fried eyeballs, which he finds delicious, but Link corrects him and explains he brought the frog because of its medicinal properties. The Lake Scientist creates a solution of Eyedrops for Biggoron from the Eyeball Frog.
