Flippers



Zora's Flippers are an item that allows Link to swim, and dive underwater. They have been featured in every 2-D Zelda game except for the original The Legend of Zelda and The Adventure of Link. A similar item known as the Mermaid Suit was found in  Oracle of Ages. The role of the flippers has been filled in the 3-D games by the Silver and Golden Scales in Ocarina of Time and the Zora Armor in Twilight Princess.

A Link to the Past
In A Link to the Past, the flippers cost 500 rupees and were required to reach certain areas of the game. Link could also use whirlpool portals in waterways.
