I attempted to start yet another comic based on if the Undertale characters could read their fan mail. This is just the first panel. These guys are sitting at Grillby's, chatting about their letters. During their conversation, MK is just kind of doing random stuff on the side (eating fries, dropping the fries, balancing the fries on his nose, etc.)
The conversation turns to how some of Papyrus' letters seem to go missing.
I haven't QUITE figured out how this will end though. XD
