Biography
Shikashi plays a small part in helping Link in his Deku form caused by the Skull Kid. After learning the secret code from the Bombers, Link enters an alley which eventually takes him to the Observatory. Here, he meets Shikashi, looking through his telescope.

When Link speaks to him, Shikashi reveals the Skull Kid was at the observatory recently and threatened to break his instruments and steal his Moon's Tear. He then lets Link look though his telescope, where he sees Skull Kid on top of the Clock Tower.

When Link zooms in on Skull Kid, a tear falls from the moon, which Shikashi lets Link keep for himself and ponders how Skull Kid got on top of the Clock Tower.
