It's gotta decode something, right? And probably something in the first half, since "AXOLOTL" is the keyword for the message in the credits.
I'm sort of thinking that the "Hidden deep within the woods..." line that you use to decode the bus seat message is hidden somewhere, and "SHACKTRON" is what you use to decode that. But I've been combing through the whole thing and I'm still coming up empty.
Anyone else trying to track this down?
