Creep

Big Keeses, also called Battle Bats  and Bats, also formatted as bats, are a species of Keese which appear in The Legend of Zelda: Link's Awakening. They have a black body with two white and green wings. Big Keeses appear during the fight against the Grim Creeper. During the fight when the Grim Creeper plays his piccolo six Big Keeses appear. He then points his piccolo forward, causing the Big Keeses to dive towards Link. Big Keeses can be hit while diving. If six Big Keeses are defeated when they attack, the fight ends. If any Big Keese fly off of the screen when they attack, the fight continues and six Big Keeses appear when the Grim Creeper plays his piccolo again.

On top of the Eagle's Tower two Big Keeses appear above the Grim Creeper. When the Evil Eagle appears the Big Keeses are blown off the screen.

Zelda Universe

 * "Battle Bats is the name given to the six Keese controlled by the Grim Creeper in Eagle's Tower."

The Legend of Zelda: Link's Awakening

 * Player's Guide: "The Grim Creeper controls the six Bats at once. Destroy all of them before any of them flies away. If one escapes, you must defeat all six again."

The Legend of Zelda: Link's Awakening DX

 * Prima's Official Strategy Guide: "These bats arrive in groups of six when summoned by the Grim Creeper in the Eagle's Tower. Destroy them all quickly or all six will reappear and you'll have to face them all again."

Trivia

 * Zelda Universe accidentally categorizes Big Keeses as enemies appearing in Zelda II: The Adventure of Link.
 * In the Player's Guide for The Legend of Zelda: Link's Awakening, it states that Big Keeses are "known as Keese in some regions of Hyrule", despite regular Keeses appearing in the game, and the book later calling them using the Big Keese name. Zelda Universe refers to Big Keeses as a group of Keeses.
