A peluda's back and tail are covered in sharp black quills. A creature that strikes a peluda with a melee weapon, an unarmed attack, or a natural weapon takes 2d4 piercing damage from the peluda's quills and risks being poisoned. Weapons with reach do not endanger an attacker in this way. Any creature that grapples a peluda takes 3d6 points of piercing damage and risks being poisoned on its turn each round.
