Spinner

The Spinner is a gear-shaped spinning-top item found in.

Location and Uses
The Spinner is guarded by the ghostly entity known as Death Sword in Arbiter's Grounds, the fourth dungeon, though it's unknown how long it has been there. The item also serves as an important weapon against the dungeon's boss, Stallord.

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 essential for fully navigating the Arbiter's Grounds as it allows Link to drift across sand without sinking. The Spinner also features a spin attack that Link can initiate to hurt nearby enemies. Additionally, ifLink uses the Spinner before falling or jumping off a high cliff, he'll be slowed down considerably and take no damage upon landing. He can also control his descent as he falls.

The Spinner is useful to break the defenses of the boss, Stallord, first in its main body, and later on his head. It is also the principal item used to unlock the Mirror of Twilight from within the Mirror Chamber after exiting to the roof of the dungeon. After Link leaves the Arbiter's Grounds, the Spinner is rarely required, with the exception of the City in the Sky. Here Link finds some more mechanisms which must be operated using the Spinner, and it can also be used to safely move over the blue tiles which otherwise fall away soon after being stepped upon. The Spinner is also required to obtain two Heart Pieces hidden in Hyrule Field.

Theory
Because the Spinner is used in the City in the Sky to manipulate and power the bridge mechanisms that connect the various floating buildings, it is theorized that the Spinner is perhaps an Oocca creation.

Trivia

 * The Spinner is the only dungeon item (besides the Light-infused Master Sword) in Twilight Princess that doesn't have a targeting cursor.
