In "The Golf War," Polly begs Big Henry not to go into the depths of the miner hole, due to a deadly gas leak. Henry ignores her and embarks on the suicidal mission. He later peers at a crude drawing of Polly and himself before he dies.
Polly is young, reflected in her small stature, large blue eyes, and orange freckles. She is yellow in color with light red-brown hair worn in pigtails. She wears periwinkle ponytail holders and shoes, and pink overalls with a lavender t-shirt.
