Gonna keep this relatively simple! I know we expand on our eye colours constantly throughout the year, so here's another funky one to add onto it!

With the introduction of BO eye 'fails', these I imagine would work semi similarly!
When breeding a parent who has sectoral eyes, there 'would' be a chance that they can fail sectoral fragmented- A sub-sectoral with the second colour/sect only in one eye rather than both.

I don't know how likely this can be implemented, but since BO Eye Fails already exist, I can't imagine it'd be too hard? Who knows!

Here's some examples (just two . but) of what I had in mind- these aren't exactly from set sect colours, but they at least pose a leetol example!
