Drop Bear (Australian)
The drop bear (sometimes dropbear) is a hoax in contemporary Australian folklore featuring a predatory, carnivorous version of the koala. This imaginary animal is commonly spoken about in tall tales designed to scare tourists. While koalas are typically docile herbivores, drop bears are described as unusually large and vicious marsupials that inhabit treetops and attack unsuspecting people (or other prey) that walk beneath them by dropping onto their heads from above.
Around the size of a leopard or very large dog with coarse orange fur with some darker mottled patterning (as seen in most Koalas). The creature is told as a heavily built animal with powerful forearms for climbing and holding on to prey. It lacks canines, using broad powerful premolars as biting tools instead.
