Premise
When 12-year-old Kelly begins to experience changes in her body, she, along with Petey and Oscar, once again visit Dr. Lendon Smith, who uses an animated film that explains in detail (via Smith's narraration) of how teenagers, especially young girls, experience adolescence and how her body changes.

Critical Reception
As with the first outing, it also had its share of criticism for using a daytime program to showcase what they saw as sex education. However, this sequel was not as popular as the first outing.
