Final temple/Battle

[Ike013]

I have all the medaillons and completed the secret temple. I know where the cave with the 7 colored candles is located. But how do you activate the warps?

Or am I missing something else?

I found the solution myself and completed the game with 100%

In shell village talk to the mayor and then do the same in piece of heart village. You'll learn the third song which will open the passage to the final temple
