Being covered in sharp needles is great, but covering those needles in poison is even better. Hedgehogs perform a ritual called anointing, actively seeking out toxic plant matter to chew into a noxious, frothy paste. They contort their bodies to violently lick the toxic foam all over their spines, upgrading their physical armor to chemical warfare.
