Lulu the kangaroo(1) (pictured eating an apple) is one of the amazing animals Brad Steiger talked about. She won an Australian National Animal Valor Award for helping save her master, Len Richards, a farmer who was seriously injured by a falling tree branch. Lulu barked like a dog to call attention to his plight, recounts CNN(2).
