The Hairy Frog
No, it’s not the hairy frog's hairs that play a part in its chief line of defense. Its main trick is breaking its own toe bones. What does it do with the broken bones? Well, basically, they push them through their skin and use them like crazy as wolverine style claws to ward off would be attackers. Sure, maybe its bones aren’t made of admantium, but it’s still pretty badass nonetheless.
