Red kangaroo

Male red kangaroo's are really strong. with one kick could make another kangaroo seriously hurt.

So its a good thing red kangaroo's have a thick layer of skin or something. (I forget)

and those kicks don't hurt as much. when other males try to be the leader of a different group the leader male comes and kick boxes the opponent which means it kicks and boxes the other male. the one who won the battle becomes the leader or stays the leader. The males are red and the females are sorta blue. And females as most of you might know are the only ones with  pouches. Large hawks can carry away a a baby kangaroo (joey) so when they see the danger the joeys hop into their mothers pouches before the hawk can get them. other dangers like dingo's come up to attack the leader rushes the herd to a large pool of water

and then the male tries to drown the dingo. the dingo will soon give up and leave them alone

and the herd will live in peace for a while.
