Okay, this is gonna sound a bit weird. I was playing OoT (actually on Collectors Edition, but i figured i should post here) and i just got Epona. I exited the ranch from the back wall, not one of the side ones. After the little thing with Link on Epona being all dramatic, I regained control, only to find myself staring at Epona's hindquarters. From that angle, i could clearly see what looked like a tatoo on Epona's belly of majora's mask, in black ink.
Has anyone else seen this? or was it just a trick of the light?
Umm, I'm pretty sure I know what it was. Partly a trick of the light, and partly what i think were black ropes on the bottom of Epona's saddle. Still, go ahead and try. i posted above exactly what i did.
