In "The Son of Neptune" by Rick Riordan, there's an amusing conversation between Percy and a whale. Percy asks the whale for a ride towards Portland, highlighting his urgency and specific destination. The whale, however, uses playful language, referring to Percy and his companion as seals, indicating their vulnerability in this oceanic environment.

Percy clarifies that they are not seals but mentions he has a satchel filled with macrobiotic beef jerky. This quirky exchange shows Percy's resourcefulness and humor. The whale, initially repulsed by the idea of the jerky, eventually agrees to help Percy and his companion on the condition that they won't try to feed him the jerky, establishing a comical deal between them.
