Rocco the boxing kangaroo pounds the heavy bag

Just a bizarre clip from Australia of a tame "boxing" kangaroo called Rocco striking a punchbag.

Although the scene may seem odd, Rocco's behaviour is actually perfectly natural.

Male kangaroos will square up to anything they think is a threat or rival and try to beat it up.

They may look like they are boxing but actually, they use the front legs to hold and the back legs to kick.
