Apparently one tree isn't big enough for two crazy koalas, and they decide it's survival of the fittest.

As the two furry marsupials match each other blow for blow, the one on top clearly has the advantage and pushes his opponent out of the tree and onto the ground. 
Instead of getting back up to show that furry fighter who's in charge, the defeated koala gives up and sits under the tree, crying and thowing a tantrum about the loss.

The video was uploaded by Alicia Alexander on Jan. 2, and according to the Australian Koala Foundation, that's right in the thick of breeding season. Male koalas are working harder to attract the females, so they become louder and more aggressive.

Alexander had good news in the video description. "The little koala won as it had claimed the the tree by nightfall," she said. "I felt so sorry for this poor bubba. It was heart breaking to watch and so hard to not to go comfort it. I try not to interfere where possible."
