where is the cannon room and which temple
---
i got the wii and the Loz TP
The Cannon Room is right beneath the "Kids'" house in kakariko village. You have to restore power to the dominion rod, and then move the statue.
As stated earlier, do not save and quit in that room otherwise the guy disappears, and then your game glitches... so ya, save after you finish with the room, like when you warp the cannon to lake hylia...hint hint.
