Wii Menu Mii #1(WaraWara Plaza)
Wii Menu Mii #1 originally appeared as one of the 90 Miis to appear in the WaraWara Plaza when the Wii U is either disconnected to the Internet or can not connect to Miiverse (which nowadays, is always, as Miiverse shut down in 2017). He hasn't appeared in any game since. He, along with the other 89 Miis, can be found in a file inside the Wii U NAND named 1stNUP.xml, with his Mii data file encoded in base64.
As with all WaraWara Plaza Miis, he was originally made on a Wii U/Switch (4), his creator name is NINTENDO, his Mii name in his Mii data file is NINTENDO, has Copying turned on, and Sharing turned off. His height is set to 31 and his build is set to 61.
His Mii data file contains unused data. Specifically, his facial hair color is set to the 2nd option.
Since all WaraWara Plaza Miis are named identically, their names on the Mii Library are using the game/application the Mii normally stands under in the WaraWara Plaza. The numbers use the internal ordering of the Miis in the 1stNUP.xml file. In this case, this Mii stands under the Wii Menu application.
Wii Menu Mii #1 will speak with a regular expression and says text.
Like all WaraWara Plaza Miis, Wii Menu Mii #1 does not appear in any promo art.
