porcupine quills that make other animals ..... by Work first

Porcupine quills serve as a fascinating defense mechanism, deterring predators and other threats through their sharp and barbed structure. When a porcupine feels threatened, it may raise its quills, making itself appear larger and more intimidating. If the threat persists, the porcupine can release its quills by either lashing its tail or making direct contact with the aggressor.
