So I was going though the websites I had linked in my cool websites page to see if I gotten any replies to my guest book messages and in my message for Alice's website I asked what they used to make thier mii and they replied with a link this mii creator
This mii creator is so cool! They have some custom stuff you can put on the mii too! I didn't see a witch hat to put on my mii but that's fine. I found horns to use instead :3
They have a section where you can pose your mii too and I was having so much fun with it!
The developers havent finished guest mode yet so you will need to sign in using a discord account and join thier discord server for now. And from watching thier video introducing the creator it seems in the future you can use this for thier other apps too which is so cool!
