The background behind this is very interesting.

So if you don’t know, Kangaroos are pretty aggressive, but they aren’t total idiots. They will start an encounter by punching or slapping their opponent to size them up. If the strength of the other Roo’s punch is too hard on them, they will rightfully imagine that their kicks will be much more devastating by comparison. In this instance, the Kangaroo with the weaker punch will likely be intimidating into retreating. If neither of them feel that the punches were strong enough, the kicking will commence.

However, Kangaroos are not particularly suited for punching. Sure, they can, but their body shape isn’t ideal for it, hence the massive legs. Humans, however, are very well suited for punching, and if you’re in decent shape, your punch will undoubtedly be stronger than most any Roo you’ll come across.

For this video, that punch made the Kangaroo realize something: “Dear god, if his punch was that strong, what the hell is his kick like?!” In reality, if you kick a Kangaroo, you will be showing your weakness, and the game is up. But the Roos don’t know that. As long as you can play their intimidation game, you should be alright, but don’t push your luck.

It’s a bold move to be sure, but it paid off in this instance.
