METOXLE!
This small, furry mammal is about the size of a badger but possesses webbed feet and a thick, paddle-like tail, allowing it to move quickly through water. Its most terrifying feature is its mouth and tongue. Its teeth are naturally coated with a highly acidic patina that allows it to eat through steel, and its long, slender tongue is coated in a paralyzing neurotoxin that it can launch up to 30 feet to bring down prey.
