Becky, look at these wombat bums, they're so perfect!
While it may look cute and fluffy, a wombat's bum is their biggest weapon. They're made up of four fused plates surrounded by cartilage, fat, skin and fur.
They can use their bum to block or even potentially to crush the skulls of predators against the entrance of their burrow. 😮
