It's possible you're thinking of a different character or a different book in the Percy Jackson series. Could you clarify what you're looking for?
For example:
* Are you sure it's not "Gladiolus"? While not a named character, "gladiolus" is a type of flower mentioned in the book, and it could have been mistakenly remembered as a character name.
* Do you remember any other details about this character? Their appearance, personality, or any role they played in the story?
* Is it possible you're thinking of a different book in the Percy Jackson series?
Once you provide more context, I can help you identify the character you're thinking of.
