The porcupine represents chance and opportunity. When One Eye hunts in the wild he sees a Lynx attempting to poach a porcupine. The lynx pounces, piercing himself on the spiny creature's quills. One Eye takes advantage of the chance encounter and opportunity, waiting until the porcupine dies of exhaustion to make his move.
