Other forms: porcupines
A porcupine is a rodent covered in long defensive quills. A porcupine's quills, startle a porcupine, porcupine tracks.
The quills are modified hairs and cannot be shot, whatever the stories say — they detach on contact and are barbed, which makes them very hard to pull out. The name means spine pig, which is exactly what it looks like and not at all what it is.
