Mii718 is an unused Mii found in the WaraWara Debug. When the Wii U originally shipped with system version 1.0.0, Nintendo accidentally left in old unused WaraWara Plaza files in a folder labeled "Debug". These were removed in the following system update. Many are in completely different formats than the one used by the final version of the WaraWara Plaza, but it's possible to still extract data from all of them. They, along with another 28 Miis, can be found in a file inside the Wii U NAND named follow_post.xml, with her Mii data file encoded in base64.
As with all WaraWara Debug Miis, they were originally made on a Wii U/Switch (4), their creator name is no name, has Copying turned on, Sharing turned on, the MAC is A4-C0-E1-F8-1B-FF, and unlike the WaraWara Plaza Miis is a valid Mii that can be saved to the Mii Maker. Their Mii name is Mii718 and their Mii ID is D0-00-02-CE. While it may seem possible to calculate a creation date from this, the time/date portion of the Mii ID is the number 718 in HEX, and since the Mii name has the same number, it's likely this is just used as a way to number the Mii rather than a proper time and date. Their height is set to 75 and their build is set to 62. While they do have unused nickname data, it is just junk data that can not be turned into any readable letters.
Their Mii data file does not contain any unused data.
WaraWara Plaza Miis have many different official texts for different official languages. However, as all WaraWara Debug Miis were simply meant to be used for testing, no localization was ever done for them. So, at most, only two entries will be listed - the original text and the text translated into English, should that be necessary.
In the follow_post file, Mii718 will speak with a regular expression and says text. Their post has 3,939 replies.
Their appearance is heavily shared with that of Parental Controls Mii #2 from the WaraWara Plaza. It's clear that Mii718 is an earlier version of Parental Controls Mii #2. However, it's important to note that unlike other WaraWara Debug Miis that later appear in the WaraWara Plaza, Mii718 and Parental Controls Mii #2 have different genders - while Mii718 has their gender set to female, Parental Controls Mii #2 has their gender set to male.
