Turn on your 3DS, select mii maker, and select create new mii and select either start from scratch or create from photo. (I personally prefer start from scratch)
Then pick the gender (male or female) and you're ready to go!
just make a mii and go to the plaza and choose the one you want to be the main mii!
mii plaza : 100 Mii parade : Unlimited
Yes you can create Mii's on the Mii plaza on the Wii menu.
Mii Plaza is for Streetpass content. When you pass by another person with a 3DS, the two systems will exchange data, and their Miis will show up at the plaza. Each Mii can be used to play the Mii plaza games, 'Puzzle Swap' is the default game, though more can be purchased.
One of your Wii friends has posted a mii to you, and for some reason, instead of telling you that a wii friend posted you a mii and keeping all your miis, it put the mii posted from your friend into your mii plaza, and took out one of your normal miis. Unfortunately, you will have to delete the posted mii from your friend and make your deleted mii all over again. I don't think you should need a password. I don't know why this happened. Its very, very strange.
Make very awesome miis!
I'm pretty sure all Miis have navy blue pants. Unless you mark them "favorite" which makes their pants red/ The way you see Miis with blue pants is because if you go on Mii Contest Channel, and you go on posting plaza, you see other people's Miis, and because they are other people's Miis they have blue pants. (You can't edit Miis with blue pants)
It is a channel where you can post miis and you can also enter and judge miis in contests. You can see others people's miis that they posted and i have to admit some are pretty good. It is also interesting that some artists are on the wii and make creations using miis. It is a cool channel because you do not have to pay for it. All it does is take up saving space and just a little.
you can have unlimited miis in your parade
Miis with blue pants are miis that do not belong to you. You get these miis from the CHECK MII OUT CHANNEL which you can only get if you have WI-FI!
yes if someone takes your mii from the mii parade and deletes it.
You can create lots and lots of mii's and transfer on the mii parade.
