Just a bizarre clip from Australia of a tame "boxing" kangaroo called Rocco striking a punchbag. <br /><br />Although the scene may seem odd, Rocco's behaviour is actually perfectly natural. <br /><br />Male kangaroos will square up to anything they think is a threat or rival and try to beat it up.<br /><br />They may look like they are boxing but actually, they use the front legs to hold and the back legs to kick.
