Knuckles (The Nut Job)

Knuckles is the newest member of the gangsters ran by King whom he introduces to Lucky and Fingers. He is silent, wears black and doesn't hesitate to do anything for money, even when some lives are on the line. He is also able to hear the dog whistle, which Lucky owned to quiet Precious before he tossed it out and the dog whistle ended up in the paws of Surly and the Liberty Park animals
