Uh oh - you neglected him or you treated him harshly, listen to him roar. Oh and now he's sad. He doesn't like to be mad. Watch as he sulks away, maybe if you sing to him or scratch his head he'll be happy again. Oh and watch out, if he knows you're around and you're neglecting him he just may get a little mischievious, and in that case there's no guessing where he'll go!
