In a riff on the classic cautionary tale "The Three Little Pigs," Paul Carrick retells and imaginatively illustrates this story of three robot brothers. When Mother Robot finishes programming them, it’s time to send them out into the world. But she warns them to be careful of Wolfgang the Recycler. If he catches them, he’ll use their parts for his own ill-gotten gains. Rod is a mama’s robot and desperate for nurturing. Slick is vain and easily won over with a compliment. And Dudley is . . . well, a dud who likes mud. Can they protect themselves from the greedy Wolfgang? The illustrations in WATCH OUT FOR WOLFGANG are made of shaped plastic, wires, bits of screen, and other recycled materials.
