If you want to add a little spice to your session, pick "Chaz." He makes a cool entry, walking in with his "horn" in a blue case, sets down the case, opens it, and then attaches his horn to his face. If you make a mistake in a program, Chaz will sound a sour note, pull on his horn and then it snaps back and slaps him in the face, or says, "Oh man!"
