now that I think about it, it looks like the monsters have their own number system as well. what if "X" isn't "this could be anytime between 2010 to 2019," like we thought (in other words, a variable), and it's instead actually a NUMBER in the monster system. this also may explain how papyrus is "12 numbers away from double digits" in his follower count on UNDERNET.
