Dear @ryivhnn, Who invented the drop bear?😳
Koreans coined the term battle koala after seeing the fierce fighting of koalas.😄

Drop bears are a carnivorous version of the koala (they look exactly the same) so-called because they hunt by dropping from trees onto prety passing beneath and have been known to attack humans. They don't like the smell of Vegemite so if you are walking in drop bear territory it's advisable to smear it on the back of your neck and ears to deter them.

they're entirely fictional, it's a joke that Australians like to play on visiting tourists sometimes :)

I understand! Koreans were surprised to learn that koalas are excellent wrestlers.😄
