“I drew a koala for class - then it ate my paper.”
“This here's a rare koala! And just lookit those fangs! Wait... why's it coming at me?”
“Aww, how cuuuu- HOLY CRAP, IT'S EATING HIS FACE”
Koalas are a seemingly harmless species of bears that are cute and cuddly - until they start walking toward you. They do not like shiny objects (including camera lenses) and will attack anyone having such things. They also don't like making eye contact with anyone. Anyone. At all.
Do you want to end up like Steve Irwin?
If you don't, stay away from the koalas.
If you do... I suggest you visit this nice place, called the 'asylum'...
