First, get the key to open the door
to the fighting arena. After getting the key and
opening the door, go inside and wait for the Boss to
appear. Next, watch were he throws the barrels, and if
they are in the correct location, shoot them back at
him using the buttons on the ground. Note: Watch out
when the Boss throws a lot of barrels -- you cannot
shoot them back at him. Also, watch out for the
coconuts that fall a little while into the fight.
