While this isn’t an OC, I recently noticed that Hippogriffs and Seaponies have pupils of a dark color based off their iris. it is not black, and I wanna mention this as many places as I can, as I wanna at least make one Seapony character (not a Hippogriff, purebred Seapony) and also a Hipogriff species swap some day, so I wanna retain this information in my head, and remind others. Cause I think it’s a neat little trait.
