Pig Won't is a bad natured, irresponsible, and grumpy pig who is the opposite of his brother, Pig Will. He appears in Richard Scarry's Please and Thank You Book and Richard Scarry's Pig Will and Pig Won't. He also appears in The Busy World of Richard Scarry and Busytown Mysteries. In The Busy World of Richard Scarry, he is voiced by Stuart Stone, even when his voice deepened during the show, just like when he voiced Ralphie on The Magic School Bus. In Busytown Mysteries, on the other hand, he is voiced by Richard Binsley. In the Pig Will and Pig Won't Book, by its end, he becomes Pig Me Too by learning to behave better. The same thing happens in a certain chapter of Richard Scarry's Please and Thank You Book, but in a different plot.
