'm not sure how he would react to a ball dropping from the sky and hitting him in the ribs
Luckily that would only be possible if he stood up on his hind legs and pumped up his chest, which would be quite remarkable.
I laughed very hard when I pictured that from a moment. I was thinking more downward glancing blow from above because their rib cage is a big bulge on the side of their body. I can say I've seen him take multiple headshots, and he was completely unaffected. He's designed for headshots after all.
Hahaha! I guess I starte humanizing the sheep a little too much haha!
His headshots do look beautiful indeed ;<)
