I'm pretty sure the Redeads in
OoT aren't wearing masks. Those are their faces. A mask is made to resemble their face, though.
With ESRB standards going down, I wouldn't be surprised by a T rating. Especially since Zelda has been becoming more mature over time. Though we're still seeing some games like
TMC and
PH on the handhelds that retain the younger feel.
