Why can they fly?
Why can sheep fly? Well, why not? This is just another playful sheep that is going against the crowd, by proving than you can be different, even if everybody thinks you´re crazy.
He doesn´t nessesarily think everybody should fly, then it wouldn´t be special anymore. He thinks that by showing the world that he can fly, making it normal, maybe somebody out there will dare to do something that they never thought they could do.
The world might need sheep that stretches the limit of what you can and can´t do, in a peaceful and good way.
What if it was more normal that sheep could fly than not?
