That's a great picture thanks for sharing
I do recall their being two different placements for Twinkle Eyes hoof stamps. I can't remember if any conclusion was drawn as it was discussed a long time ago, but I do think two runs is likely given how much variation there is. It's not just hair colour, it's eye style and colour as well as hoof stamps that are different.
It might be worth discussing Spain twinkle eye hoof stamps again!
