Title says it all, I'm suggesting a helmet accessory that look like a pair of googly eyes, as it's a accessory it won't change the eye shapes of your actual knight, the pupils are (always black) not affected by your knights personal colour, they can be attached to all helmets, adjusting their size and location according to the helmets eye hole location and placement.
YUS! His approval levels it's + OVER 9000!!!!!!!!!!
