I’m wondering what other theories might be out there on the ‘waving, clapping, talking miis.” Those miis that clap and wave and then shout (silently) seem to be giving us some clue – I just can’t figure it out yet. It seems that they are positioned near places that turn out to be great cheats (or do we find the cheats because they are there?) One slightly perplexing mii is the one down by the little village near the wind towers (because he is near a door just makes me think that maybe… someday…) Most perplexing to me is the one hiding out up on the ledge that overlooks the ruins road. To be almost hidden up on this out of the way ledge makes me think that we should be up here with a purpose????
Any theories or do I need to just get a life

Ah "grasshopper", we all must get a life. Those Miis are very perplexing for sure. I personally think they are there just to make us think and look and therefore they work. I do agree though that some are in locations that beg to ask "What are you doing here?"

I think all the Mii's are crazy! They run right at you when you're cycling toward them at full speed, fall flat on their faces running on smooth ground and insanely jump around clapping for no reason.

Some of the Mii's seem to point to the way of the balloons and flags. I have noticed that wherever there is a ballooon or flag there is a Mii. Just Mii thought!
