These green behemoths are created by sorcery. They start out four times the mass of a Furre, and stand one and a half times as tall. They are used to dig moats, build castles, and protect forests against logging. As they age, they grow larger, and there are even legends of Curcupines the size of windmills.
Up close, they attack with hard, armor-cutting claws. Their tails can be swung to shoot magical, armor-piercing spikes as long as a Furre's forearm.
They can be peaceful, given care and guidance, but without a caretaker, they become dangerous. If rewarded for it with praise, they learn to love destruction and a Curcupine on the rampage can easily wipe out a village. With effort, they can even claw their way through castle walls.
