Seahat
The Sea Hat is a larger version of the common Peahat found only out upon the waves of the Great Sea in The Wind Waker. It is said to be related to Pea Hats, but this is more than likely only based on appearance. Sea Hats congregate in packs, and hover close to islands in a number of areas of the Great Sea. Highly territorial, they will attack anything that gets too close to them.
Sea Hats attack by ramming their own bodies into ships in order to knock its crew overboard, where they are helpless against the Sea Hats' unrelenting attacks. When attacking, the Sea Hats dip their bodies into the water up to their nostrils and propel themselves quickly towards their quarry; however, they do not often gain the element of surprise, as their movement through water creates a strange, motor-like sound as their blades hit the water at rapid speed. They can only move above water.
These flying fish can be killed by use of two Boomerang hits or one hit from any other projectile weapon. With the Boomerang, the first hit will cut its wing-fins off and leave it immobile and helpless in the waters below where it flew — the second attack from a boomerang will kill it. If their fins are chopped off when they are hovering above an island, they will slowly bounce back into the sea.
