I was messing around in Shadow of the Colossus being bored and stuff. Agro is my trusty, immortal horse; repeat, immortal. Falling off cliffs usually don't phase him so I ran him off one. But he didn't resprawn. Puzzled, I made my way on foot.
So I was walking around the world for awhile and uh... Found him dead. xD
Note: He keeps haunting me. Everywhere I go, his body appears...
