Wombats have fused bone like cartilage in their butts used to block their burrows from predators and apparently will twerk to defend and crush the skulls of the attackers against the burrow walls. https://www.australiangeographic.com.au/topics/wildlife/2020/11/wombat-bums-theres-more-than-meets-the-eye/
so when do the predators grow their own military helmets?😅
@holon42 but now we can say “killer wombat butt” with scientific accuracy.
