Hoppers of the world...

General information:
Hoppers of the world... that means the Kangourous. I heard that Australia, where these hoppers come from  have 40 million of them, but just a population of 14 million humans. So the kangourous are the real kings of Australia. 

Types:
There are several types of kangourous - there are smaller and taller ones - and although they look really sweet they are really good boxers. I think you can put them in a ring and they will fight down the Klitschko brothers...
