Heatwave and Quickshadow are so happy. They now have a baby boy who was just born today. They named him Hot shot. But quickly the joy turns to great concern. They are told that Hot shot has several heart defects. He has a two major heart defects teratology of Fallot, transposition of the great arteries, a small right ventricle, a blocked artery, and two holes in his heart. The doctors are stunned he is alive. He was immediately sent to Texas Children's Hospital. They were stunned about Hot shot's heart. But they saw it could be handled with open heart surgery. So Hot shot was going to begin a journey of trying to stay healthy with an unhealthy heart. He makes friends as he grows up at the heart center who also have serious defects. They all become good friends and have many surgeries while they grow up. Soon things were going to get even more hard as they go through this journey of theirs. (Humanized)
