Thanks guys. XD Digi looks just like his mom, Jessie - though she was a bit more goldeny.
When he was little he was basically a little blonde, then a dark stripe appeared down his back and gradually got wider.
It's really weird, one could barely tell he even had a pupil. However if he looks far enough either direction, the white of his eye shows. XD We call it his 'funny eye'. Creative, isn't it?
