The video explains it all....he is one big gray love bug!
His personality is just so bold, confident, and super friendly to humans.
He hates rain, though. He refuses to go out to graze when it's raining, as you can see in the video. The barn door is wide open.`` He prefers to walk through the barn, harassing Epona, eating hay....and licking and nuzzling his humans. He is soooo weird.
He also hates snow.
