Regular Bristle
HP: 2, Attack: 1, Defense: 4 Tattle: That's a Bristle. ...Totally covered in spikes. They're so prickly! AND they're impervious to fire! Even trying to get close enough to whack it with a hammer is dangerous! Seriously, its spikes will totally pop out! So, since you can't jump on it or use your hammer... you'd better use an item!
