Boo

Boo Buddies, also known as Boos and misspelled as Boo Buddles, are ghost enemies who appear in The Legend of Zelda: Link's Awakening and its Game Boy Color port, The Legend of Zelda: Link's Awakening DX. They are from the Mario franchise, and their appearance is based off their appearance in Super Mario World.

Link only encounters two Boo Buddies during the game, in a dark room in the Bottle Grotto dungeon that has the Power Bracelet. The Boo Buddies are nearly invulnerable in the dark, where they can only be defeated directly if Link shoots four arrows at them or by using the Magic Rod. The Boo Buddies move slowly toward Link even when he is facing them, unlike Boos from Mario franchise, who only go after the player if they do not face them.

Link can use Magic Powder to light the two Lamps, causing the whole room to brighten momentarily. When the room gets bright, the Boo Buddies turn dark and weaken, though when the Lamps' flames die out, the Boo Buddies return to normal. The Boo Buddies act the opposite when the room is bright instead of dark, as they attempt to flee from Link. When both Boo Buddies are in this state, Link can defeat them with a single hit from any weapon. When Link defeats the Boo Buddies or if both flee while the room is bright, a Treasure Chest with the Power Bracelet appears.
