Smasher is the name of a mysterious round creature with dog-like behavior that appears as a recurring mini-boss in and. To attack, it barks and pick up a heavy Ball to throw it at Link in an effort to incapacitate him. Link must reach the ball before he can and throw the sphere back at Smasher with his Power Bracelet, slamming the creature into submission.

Smasher is found in a hidden room in Face Shrine, in one of the "eyes" on the dungeon map. The only way to access this room is to open the wall with Bombs. After defeating Smasher a warp to the entrance of the dungeon will appear and Link can pass through to a room that contains a secret passageway deeper into the dungeon. However, if he cannot find the passageway, the rooms will loop endlessly. Smasher later appears in Turtle Rock along with other mini-bosses, where it will continue to reappear even after being destroyed.

Smasher is found as the mini-boss in the Crown Dungeon on Rolling Ridge. The only major difference from its incarnation is that the ball will disappear after a short while after being thrown and reappear elsewhere.
