I think you're running off of Miramax's interpretation of Bionicle. You see, Bionicle really looks how you think it should. For instance, there are some who think they look exactly how the sets do (no mouths at all). Others go the Miramax route and make them look similar to the sets but also quite a bit different and more stylized (mouths part of the mask or grates). Others still, including myself, interpret them as being far more organic than biomechanical (mouths separate from the mask). It all depends on how you think the universe appears. The good Doctor runs on the idea that all masks have mouths, I would think.
