Wait, what's Gale Boomerang? I know there's a regular boomerang you get as a kid, but I don't remember any Gale Boomerang.
As for me, before I get started on the final portion of the game, I'm want to get the last heart pieces and maybe a few more skulltulas. The latter I'm on the fence about. Because even if you get all 100 skulltulas, all you get is 200 rupees, which is not rewarding at all. I've already got the heart piece to beat 50+ skulltulas, and I've got the biggest extension on the wallet. Other than that, I'm not sure if I'm gonna bother defeating the rest. But I might, just for the sake of completion. As for the heart pieces, I still have 8 more to get. And they're the most pain in the butt to get. Like the Bowling Alley one, and the Dampe's race one. I'm just debating on which to do first. I'll probably get the final boss out of the way first, then go back and get all the heart pieces and skulltulas I missed. And then, it's off to download Majora's Mask.
