This definitely reminds me of a oc that I made using this Trixie base on Amino Apps, but with a lighter grayish color, and named her “Mary Sue” as a joke character. It was made because of those random GIF posts with “create your oc” caption, simply by taking screenshots per frame. It didn’t take me long before I removed it from my Wiki Entries but eventually I ended up deleting the post of my drawing on that character, so it’s definitely non-exist of this world.

I can 100% confirm that I wasn’t the one who drew this grayish Trixie.
