Lakeside Laboratory

The Lakeside Laboratory is a location in Ocarina of Time. Located in the shores of Lake Hylia, it is home to a Lake Scientist who tries to resolve the lake's many mysteries.

Features
Inside the laboratory, Link can find the Lake Scientist's experiments as well as a big pool. Link can dive in the pool, and the scientist will tell him how many meters he dove. If Link possesses the Golden Scale, he can dive to the bottom of the pool and touch the floor to receive a Piece of Heart from the scientist as a reward for his excellent diving skills. The young hero can also find a Golden Skulltula hidden inside one of the boxes at the bottom of the pool. Moreover, there is a cage where a motionless shark is imprisoned. It is presumed dead. There are also 2 glass aquariums on the desk behind the scientist, one of which holds 2 shrimp-like creatures, and another that holds a small octopus-like creature. In the 3DS version, there is a frozen Octorok instead, and the shrimp are no longer present.

There is a patch of soft soil outside the laboratory where Link can plant a Magic Bean, enabling access to the roof. The roof can also be accessed by using the Scarecrow's Song. Atop the roof is a ladder that leads to a small platform that oversees Lake Hylia, and it is also where a second Piece of Heart can be obtained.
