The arrow is one of the two things the Gray Fox gives you, along with the Boots of Springheel Jak. The arrow has a key-shaped arrowhead, and, once fired at the lock under the statues, opens the door to the White Gold Tower via a fireplace inside the guards' barracks. It is recommended that the player take a few practice shots before firing it, and fire above were they want it to land.
