How do you defeat the temple of fire in legend of Zelda phantom hourglass?

Answer 1

well...just follow all of the maps and all of those things that you have to slash with your sword and they give you info...and then wham! youre already at the boss! all you have to once u get to the boss is that you have to use your boomerang that you just got and youuse it to bring all three weird things together. sometimes it takes a while, but then the real boss will appear and just keep slashing it with da sword ...then do that a couple more times and then you rescue leaf, the spirit of power. yay!

Answer 2

Ok, if you are talking about the moster at the end then you use what they gave you: the boomarage. Click on the item box at the right or left hand corner and select all three deamons and throw. They will morphore together into the guy again and then ATTACK! Then keep doing this until you kill him.
