Fran is thrilled when Charlene's scent gland comes in, as that means she'll be able to attract the one male who finds her acrid stench alluring — but Charlene freaks out when that "one male" is the school janitor, Ray and sets out to change it by searching for The MacGuffin Lily.
Tropes:
- Abhorrent Admirer: To her horror, the one attracted to her scent is the boorish school janitor.
- Big "NO!": Robbie gives one upon realizing the usual method to taunt his sister no longer works.
- Boyfriend-Blocking Dad: Earl fully intends to forbid Ray from seeing Charlene at first, but he finds that he and Ray have so much in common they bond instantly.
- Character Development: Charlene's journey not only changes her scent but also makes her immune to Robbie's usual taunting.
- Cool Old Lady: Ethyl agrees to reveal the Lily's location so Charlene won't have to marry a younger version of Earl.
- Flower from the Mountaintop: The MacGuffin Lily, the only known substance that can change a dinosaur female's scent, only grows in a field atop a mountain. Charlene makes it all the way to the top, only to find that the field had been cleared away to make room for a photo booth. When she returns, however, she finds that her scent had changed nonetheless, apparently triggered by her desire to improve herself and not settle.
- It's the Journey That Counts: Even though she failed to get the MacGuffin Lily, Charlene's scent changed on her own, which Ethyl thinks happened because she was willing to change her fate by undergoing the journey in the first place.
- MacGuffin: The MacGuffin Lily, its name a very obvious bit of Lampshading.
