The Legend of Zelda: Ocarina of Time
Link searches for one after being told by Mido that he will not let him pass without a shield and a sword, blocking him from seeing the Great Deku Tree. The first Deku Shield is purchased from the shop in the Kokiri Forest for 50 Rupees.
As well as being able to purchase another, the Deku Shield can also be found inside chests in certain dungeons as a replacement should Link lose his current one. This is in due to the fragility of the shield, which will burn if it comes into contact with fire.
