When you enter the room with the fire breathing snake you will see
five columns around the snake pool. Slash those colums with your
sword or staff and knock them onto the snake. For best results, use
L1 or R1 to move to the next column, then hack away. If you're quick
chance to breathe fire.
After all of the columns fall, the fire will stop and the snake will
start biting at you. Dodge him when he strikes by pressing L1 or R1.
When he starts to swing around the pool strike him in the head. Do
this four or five times and he's dead!
