This is the sequel to Sarge's Heroes. It introduces several new characters, and the concept of "Plastrification". Plastrification, according to Dr. Madd, is a condition that occurs when a soldier from the "Plastic World" spends too much time in the "Real World" causing the hardening of the limbs and the forming of a plastic base. However, the character Bridgette Bleu has developed a serum that reverses the effects of plastrification.
