Man on a Roof
The Man on a Roof is a Hylian man who somehow managed to get onto the roof of Granny's Potion Shop in Ocarina of Time. He can be found here when Link is a Child, as well as when he becomes an Adult. As an Adult, Link can reach the top of the roof by using the Longshot. While not intended, Link can reach the top of this building as a Child, by climbing to the top of the watch tower in the center of Kakariko Village, and performing a side jump, allowing Link to climb up on top of a fence, where he can then reach the rooftop. Reaching the roof and meeting the man will give Link a Piece of Heart.
