Cob, Knob, Drob, Gob and Rob are our neighborhood trouble makers. They all range between 2 and 4 and a half inches, but don’t let their small stature fool you- they pack a big punch. These little guys are known to terrorize backyard critters, primarily Red the Cardinal. No matter how many times Red pecks at them, they’re sure to hold up. Purchase them today, please- we want to get them out of the neighborhood.
