The Mii Channel is where the Mii Creators see their Miis. The place is considered the pathway to the Mii Creator's personal Mii Plaza. Miis cannot leave the Mii Channel, unless freed upon by the Mii Creator, just like the other Wii Channels.

If a Mii Creator was to press A,B,1 and then hold down 2 he would then be able to move Mii's to the Mii Maker World on the 3DS. This minor glitch also works on the DS.
