Prickly Porcupine

Porcupines show up in nearly every form of media. It seems that porcupines tend to fall under two distinct personality types: They're either A) the Grumpy Bear or The Eeyore, pessimistic and anti-social, or B) The Woobie, shy and lonely because no one wants to go near them.

Many works of media (particularly in Video Games) portray porcupines as being able to shoot their quills as projectiles, even though this isn't true in Real Life (North American porcupines swing their tails at predators to dislodge the quills in their faces, while Old World porcupines tend to charge backwards at their enemies instead).
