It seems like you're asking about a "special code" in a game or story called "Franktown Rocks." However, there's no widely known game or story with that name.

To help me understand your question better, please provide more context:

* Where did you encounter this "special code"? Was it in a book, a video game, a website, a movie, or somewhere else?

* What is the context surrounding the code? Is it a puzzle, a password, a cheat code, or something else entirely?

* Do you remember any other details about the code itself? For example, is it a string of letters, numbers, or symbols?

With more information, I can try to help you find the answer!
