YOU think koalas are cuddly and cute and wouldn't come after you?
You might want to think again after watching this incredible video of a South Australian woman being chased by a koala while she was riding a quad bid.
Ebony Churchill caught the strange experience on camera and posted it to her Facebook page.
It has since gone viral with more than 1.1 million views on the social media network.
"Far out, it's coming!" she is heard saying in the video
After she stopped, the mad marsupial caught up to her and began to climb on to the rear wheel of the motorbike.
"It's on the bike. Piss off!" Ms Churchill said.
"I don't know what I'm going to do now."
"Them drop bears are dangerous," Facebook user Tim Cochrane joked.
Another suggested the koala just wanted a cuddle.
Maybe, but no doubt Australia's reputation for having the world's most dangerous - and crazy animals - has just gone up a notch.
