A remote control, perhaps a few coins – or some keys.
Fairly standard things you’d expect to find on, or stuffed down the back of, your sofa.
But a koala? That’s wide.
Vicki Haines and her girlfriend Michelle came home on Tuesday to find the creature just chilling on their coach.
‘She was hiding behind a mountain bike wheel and our dog was going crazy.
‘But when things calmed down it was pretty cute, it was just sitting right in front of the heater where I usually sit with my dog,’ Haines told Australian Associated Press.
The koala was nicknamed Tuff Bugger. She was microchipped and then safely released back into the wild.
Koalas are insanely cute, but if they feel intimidated they have long claws which they use to scratch any person or thing they perceive to be a threat.
