Bustard (see Porcupine).

Source: [Anon-Animals]

A porcupine is a rodent that has auto defense in the form of spines that poke his attacker. Although most rodents don’t have much in the way of defending themselves, this fellow is difficult for other animals to do him much harm, and his spines can attack even a much larger predator and leave them wishing they hadn’t messed with him.
