One of the ways kangaroos have adapted to fight dingos (their main predators) is by luring them into rivers. When the dingo goes into the river to try and keep hunting, the kangaroo uses all of its limbs to hold the dingo underwater and fucking drown it.

Muscular male kangaroos can grow over 6 feet tall and are more ripped than @Zangief, so drowning a wild dog is pretty easy for them.

Where this gets even more fucked is that Kangaroos will do the same thing to off-leash domestic dogs that harrass them.

…. And also to people who try to save their dogs who are being drowned by a kangaroo.

Do not fuck with kangaroos, comrades.
