Location and Uses
The OoT3D: are one of the items necessary to assist in the creation of Biggoron's Sword. They are received from the Lake Scientist after giving him the Eyeball Frog from King Zora, which he initially misinterprets as a gift. After being told that it is meant to be made into Eyedrops for Biggoron, the Lake Scientist takes the Eyeball Frog and uses it to make the OoT3D:. Returning the Eyedrops to Link, the Lake Scientist urges him to hurry to Death Mountain, as the ingredients will spoil within four minutes. If Link tries Warping while carrying the Eyedrops, it will spoil instantly.

If Link manages to return to Biggoron in time, he will thank Link and use the OoT3D: immediately. With his eyes cleared, Biggoron grows excited to return to his work and hands Link a Claim Check with the promise of finishing his work within a few days.
