I think it would only work on statues that have a little hole in the middle for the 'soul' to go in.
Also, for everyone who wants the curse stone, remember: your twilight form may not be a wolf. That's Link, the chosen hero, who transforms into the "Blue-Eyed Beast." I'm just Saiyan.
For me? Hmm… wow… I think I'm only now realizing what a dearth of cool items there was for TP. Gale Boomerang I guess? Well really, I think I'd just love the Hero's Bow. It's been ages since I owned a bow that was big enough for me, and a recurve bow with a high draw weight sounds amazing. Man… i should really get back into archery.
