Boo

Boos, also known as Boo Buddies 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 Boos during the game, in a dark room in the Bottle Grotto dungeon that has the Power Bracelet. The Boos 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, which can only be seen if the room is revisited later in the game. The Boos 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 Boos turn dark and weaken, though when the Lamps' flames die out, the Boos return to normal. The Boos act the opposite when the room is bright instead of dark, as they attempt to flee from Link. When both Boos are in this state, Link can defeat them with a single hit from any weapon. When Link defeats the Boos or if both flee while the room is bright, a Treasure Chest with the Power Bracelet appears.

In the Nintendo Switch remake, a Boo figure is a prize in the Trendy Game, and can be placed on a stand in the northern household of Mabe Village.
