Grim Creeper

Grim Creeper is the mini-boss of Eagle's Tower, the seventh dungeon in The Legend of Zelda: Link's Awakening. It is skeletal in appearance, hence the name, and of an apparently cowardly disposition.

Strategy
Link will encounter Grim Creeper approximately midway through Eagle's Tower. There will be a small introduction, and then Grim Creeper will play a flute to summon a flock of Keese. Link must destroy each of these before they leave the room; if he misses any, Grim Creeper will continue to summon them. Once the Keese have been dispatched, Grim Creeper will flee for a time. He returns for the final boss battle, riding on the Evil Eagle.
