Koalas just got less cute. br br This clip, filmed in Adelaide, Australia last week, shows a rescued koala named Scar roaring.br br The marsupial's vocalisation sounds a lot like a huge human burp interspersed with a raspy, hissing noise. br br Scar was rescued during the current heatwave and is recuperating in a care centre until the weather cools down when he can be released back into the wild.
