The agency pairs them up with a child named Bamm-Bamm, who can only pronounce his own name. Although Bamm-Bamm is initially difficult to control due to being raised by mastodons, and thus has super strength, he eventually warms up to his new family.

Fred promises he will prove himself to her one day.
