Go to the Mii parade and hold A and B to grab a Mii that's in the parade and then transfer them back to the mii plaza.
You can create lots and lots of mii's and transfer on the mii parade.
Mii was created in 2006.
Mii-dera was created in 672.
To get the Find Mii II Secret Quest, you need to complete Find Mii twice, you also get the Ultimate Helmet when you beat it for the second time.
StreetPass Mii Plaza was created on 2011-02-26.
If it is from one Wii to another specific Wii and not requiring an Internet connection, then you click Transfer Mii, and on the top of the screen, a thing willl pop up, and i represents your Wii Remote. Just point on the Miis that you wish to transfer, hold in B, and drag the pointer to one of the "Remote"'s circles. Then, bring your Wii remote with the Miis on them when you play on the other Wii, go to the Mii Channel, click Transfer Mii, and then drag the Miis off onto the screen with the B button. (These Miis may not appear on the Mii Parade, however. I believe that I have at least once gotten the Miis from just my Wii in the Mii Parade.) If using a Wii-internet connection and the Miis are from randon Wiis, then just connect (the connection details are in the Wii Manual) and click Mii Channel and Mii Parade. There they are.
To unlock mii outfit A, you need to get a gold trophy in the 100cc special cup. To unlock mii outfit B, you need to unlock expert staff ghost data records in all 32 courses.
Yes you can edit your mii, all you have to do is go to the settings in one of the corners,(the corners where the settings button change all the time!)and press delete mii. Then it will ask you do you really want to delete your mii...you say yes, then it will say you have just deleted all of the data and settings and your mii for your wii fit!

In most cases, no you cannot. Most games are separate and are exclusive to either the Wii U or the Nintendo 3DS.However, there are a few games and applications that does allow you to transfer save game data. Monster Hunter 3 Ulimate and Super Smash Bros for 3DS/Wii U will allow you to transfer data from one game to another. You will need to have both games running on both systems before you can transfer. Also, applications such as Mii Maker will allow you to copy your Miis from one system to another.
Save it in your wii mote or send it to the other wii by a friend code. I also think you can send them to mii parade and pick them up in the other wii.
