Spinner

The Spinner is a gear-shaped spinning top item found in Twilight Princess's fourth dungeon, the Arbiter's Grounds. It is an ancient item created long ago. Link rides the spinner much like a skateboard, except he can only ride on it for a few seconds until the spinner loses its momentum. The device can also be attached to railings located on specific walls and allow Link to travel along the railing. It is extremely useful for navigating the Arbiter's Grounds as it allows him to drift across sand without sinking. The spinner is obtained after beating the mini-boss of the dungeon, Death Sword. The spinner also features a spin attack that Link can initiate to hurt nearby enemies.

The Spinner is the main item needed for defeating the boss in the Arbiter's Grounds, Stallord. It is also the principal item used to unlock the Mirror of Twilight from within the Mirror Chamber after Arbiter's Grounds. Sadly, after completing the Arbiter's Grounds, the item is rarely used.
