The film somehow reminds me of an area I know of in suburban Port Macquarie, it's on the way to nearby Lighthouse Beach. My sister and her ex once owned an Italian restaurant there and the area I'm referring to had a "koala hospital" in it. Obviously a veterinary station for wounded koalas because there was a huge population of these chappies along this part of the coast. Also a terrible disease which affects them in a most painful way on a bodily organ which I won't mention was running rampant through the poor critters. Hope they're fine these days though.
The main thing is the bully didn't kick it in this part of its body because all I can say is OUCH! If this had happened I can understand anyone crying like that, especially if the little guy is a male.
BTW my zoological ignorance is why I don't give the furry guys any gender specific pronouns. Not because I don't love mother nature or respect native animals because WE ALL SHOULD. NO MATTER WHAT. Had to throw that in. Too many idiots in Australia think it's nothing to shoot an animal in her/his/their natural habitat or even beat up an LGBT person in her/his/their natural habitat.
