Whirlpool

Whirlpools are found all over The Great Sea in The Wind Waker, and in Phantom Hourglass. In The Wind Waker most whirlpools appear with an objective that must be completed before the boat is sucked into the whirlpool's center. However, in Phantom Hourglass they appear as miniature tornadoes on the water that can be destroyed by the cannon. Whirlpools have also appeared in Four Swords Adventures where you would be sucked down to a small underwater cavern.
