The Legend of Zelda: The Wind Waker -
Much like Tetra said, there are two ways to defeat this Bokoblin. One is to use your shield and wait for him to attack. The other is to find a pot nearby with wooden sticks that you can use to attack. Whichever way you choose, pick up a stick and attack the Bokoblin before it attacks you. Recover anything it drops, as it may be a Joy Pendant.
