First-time campers in Australia are warned to keep their eyes out for the dreaded drop bear, also known as the killer koala.
These terrifying creatures lurk in eucalyptus trees, eyeing unsuspecting campers strolling through the woods. When you least expect it, they'll pounce on your head, pin you down, claw at your flesh and eat you alive. Luckily, there's a way to keep them away: vegemite. Like mosquitoes and citronella, drop bears can't stand the smell, so to effectively repel these mad marsupials it's advised that you cover your entire body with the thick spread.
Ok, the ruse is up: This is one of Australia's biggest urban legends (but many fall for it, so don't feel bad if you did, too).
However, a similar creature may have once existed on the continent during the last Ice Age. Referred to as the Thylacoleo carnifex, or" marsupial lion" by paleontologists, the creature was believed to be a modified koala that had teeth used for cutting as opposed to grinding and may have eaten other animals' flesh.
