Or maybe he actually wants people to create their fangames/comics and make the reason themselves; he doesn't seem to have even brought up the Unity port yet despite it being at crazy fast development. But as much as AUs and imagining is cool, the universe seems to be lacking a few things - like a jigsaw where you have all those islands of completed pieces but none to put in the middle and start seeing an actual picture though not the entire thing. I definately don't want him to answer everything myself,but if he could give some hints on how to put it all together and have some semblance of a ground to stand on for backstories and (more concise)lore, it'd be awesome.
The postcredits boss
Is Toby himself as the Annoying Dog. You get him by beating the credits sequence, but his room has 'holes that need to be patched' so you can't engage him iirc. And considering how he treats Papyrus and Toriel (especially in hard mode), he's really the last one you should encounter.
