Don't mess with the kangaroo.

Kangaroos are animals with professional boxer titles in the animal world, we can see this by how these animals train.

At first glance, kangaroos have the same body posture as humans, it's just that the height of an adult kangaroo can exceed that of an adult. Although kangaroos eat grains, they have a strong instinct for self-preservation. This can be proven because kangaroos have the ability to box both through their hands and feet. The ability to kick from the kangaroo's feet also cannot be underestimated. When kicking the kangaroo usually rests on its tail. This activity is often called “kangaroo boxing”. Usually they box to defend the right to marry female kangaroos in the area.
