Where it is

From the official guides

The type that jumps back out of the way when Link swings his sword. The red ones throw bones after they jump, so beat them with the boomerang.

A skeleton that wanders around the room. Hit it with the sword and it backs off. Drive this one into a corner of the room too, and it is easy to beat.
