Stalfos Knights appear only in the Ice Palace. They drop down from above, and then begin jumping at Link. If hit by the sword, Boomerang, or certain other weapons, they will collapse into a heap of bones, but will regenerate if not quickly destroyed by a bomb. Interestingly, their collapsed bodies can also be destroyed by a number of other items if struck a very high number of times. The most notable of these is the Boomerang, as it is not limited by ammo or magic; 56 strikes of the Boomerang are required to defeat a collapsed Stalfos Knight.
