Whirlpool Waterways "There are six magical whirlpools in the rivers and lakes which connect three warp waterways. If you dive into one of the whirlpools, you will surface in a far away body of water. You can make use of these watery short-cuts once you have Zora's Flippers."
Whirlpool Waterways can transport Link from one body of water to another once he has obtained the Zora's Flippers. There are six Whirlpool Waterways in the Light World and two of them in the Dark World. Each Whirlpool will always take Link to the same preset destination.
↑"One pair of
flippers coming up. I will give you a free bonus with your purchase. I will let you use the magic water ways of the sea folk which link lakes and rivers. When you see a whirlpool, dive into it." — King Zora (A Link to the Past)
