Ku

The Ku is an enemy found in The Legend of Zelda: A Link to the Past. They are the Dark World equivalent to the Zora Spawn. These creatures live in the water, and attack by protruding their heads to shoot fireballs at Link. They have one eye, and are a grayish-red color. Ku only move underwater, but can still hurt Link if he swims into them. His only attacks must be done on dry land or shallow water, making it difficult to successfully defeat Ku. Long-range weapons are most effective, however, if Link is lucky he can strike these creatures if they pop up close enough to where he is standing.
