The Koala, colloquially known as a "dropbear", is an Oceanykan animal that can grow up to 60cm tall and 18kg heavy. Koalas appear to be cute, Eucalyptus-munching, tree-living creatures with soft fur that couldn't hurt a thing. In reality, they are killing machines. While it is true koalas are gentle and passive animals, their body seems to possess a gland that, when in danger or lacking in protein, activates a "murder hormone". This not only changes its neurological processes to be more aggressive and engage in advanced hunting techniques, but also every cell in their bodies has its metabolism turbocharged. The result is that these fluffy munching bears turn into fat monkeys with the ferocity of wolverines when provoked or hungry. Their colloquial name, dropbear, comes from the fact that they may ambush a ground animal (such as an unfortunate person) from up in their lairs in a gravity-assisted pounce. Any experienced Oceanykan, however, could tell by pure sight when a koala is engaged in its "dropbear" state. Older natives and the like can tell if an area is dangerous by the sound of bubbling saliva and low growls in the trees.
