Like the other alpacas, Shammie too was struggling with nervousness. He was afraid he would trip or that people would laugh at his hat or worse that he would simply go in the wrong direction. As he looked at Joey, he thought, hey that kid has a great idea! I'll cover my face with my hat too! Then no one will know who I am and I won't need to be ashamed if I goof up. I knew picking Joey was a smart move...he's smart.
