Vinnie is a Mii from the Switch.
Vinnie originally appeared as the default Mii for Neksdor town's Prickly Husband role in the files of Miitopia (Switch, Demo), but unused within the demo itself. He later appeared in the full game of Miitopia (Switch). Once the player replaces him with a Mii of their choice, Vinnie would never appear again, unless that Mii is deleted. His Mii data file can be found in \cmn\storedata\npc_default_mii.sarc and is named Town01_Husband.charinfo.
His Mii name in his Mii data file is ギスおっと, which translates to "husband". His height is set to 76 and his build is set to 43. His Mii ID is as follows: 57 1F 30 E0 55 CA 43 97 9D 83 FF 88 8D F8 92 3B
His Mii data file does not contain any unused Mii data.
